NOw you are logged to the first-time console look like below

Virtual Appliance contains all required software except 3rd party storage APIs which cannot be freely distributed, they must be installed manually, refer to your storage installation.

Note: STOR2RRD is installed under user lpar2rrd in Virtual Appliance.

Configure the Storage

Now we have set passwordless ssh access to storage from our STOR2RRD appliance

  • Do all actions below under stor2rrd account (lpar2rrd on the Virtual Appliance) unless is explicitly specified root in the procedure, here use lpar2rrd since we use the virtual appliance
  • Create user stor2rrd on the storage with browse role and allow it for all domains.

Login to 3PAR Storage using putty and create using below command

# createuser -c "password" "username" all browse

 

Under lpar2rrd account create config entry

# su - lpar2rrd (user stor2rrd if it is not an Appliance)
#vi /home/stor2rrd/stor2rrd/etc/storage-list.cfg

Open port 22 to the storage and test its working or not

$ perl /home/stor2rrd/stor2rrd/bin/conntest.pl "3PARIP" 22
  Connection to "3PARIP" on port "22" is ok

Create a key pair using the ssh-keygen utility in case you do not have a one in /home/stor2rrd/.ssh

Type enter instead of a passphrase, if you have more than one storage provide another file name

$ ssh-keygen -t rsa -N ""
  Generating public/private rsa key pair.
  Enter file in which to save the key (/home/stor2rrd/.ssh/id_rsa):

$ cat ~/.ssh/id_rsa.pub

Exchange the ssh public key (import it on the storage under stor2rrd /lpar2rrd account)

# ssh lapr2rrd@3par_storage stor2rrd@3par_storage password: "password"

#setsshkey

Enter the SSH public key below. When finished, press enter twice. The key is usually long.
It’s better to copy it from inside an editor and paste it here. (make sure there is no extra blanks)

 sshrsa AF5afPdciUTJ0PYzB6msRxFrCuDSqDwPshqWS5tGCFSoSZdE= stor2rrd pubic key
 SSH public key successfully set!

Check the storage connection, you should log in without password prompt

$ ssh stor2rrd@3par_storage

Check storage connectivity

$ cd /home/stor2rrd/stor2rrd
$ ./bin/config_check.sh 
  =====================
  STORAGE: 3par01: 3PAR
  =====================
  ssh -o ConnectTimeout=15 -i /home/stor2rrd/.ssh/id_rsa  lpar2rrd@3PARIP  "showuser"
  connection ok

Schedule to run storage agent from stor2rrd crontab (lpar2rrd on Virtual Appliance, it might already exist there)

$ crontab -l | grep load_3parperf.sh
$

Add if it does not exist as above

$ crontab -e

# HPE 3PAR storage agent
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/load_3parperf.sh > /home/stor2rrd/stor2rrd/load_3parperf.out 2>&1

Assure there is already an entry with the UI creation running once an hour in crontab

$ crontab -e

# STOR2RRD UI (just ONE entry of load.sh must be there)
5 * * * * /home/stor2rrd/stor2rrd/load.sh > /home/stor2rrd/stor2rrd/load.out 2>&1

Let run the storage agent for 15 – 20 minutes to get data, then:

$ cd /home/stor2rrd/stor2rrd
$ ./load.sh

Wait for few minutes and refresh the web console and you can start the performance monitoring

 

Reference

Conclusion

We have successfully deployed STOR2RRD appliance in our environment to monitor the 3PAR storage system, it really awesome product it was the solution to our monitoring challenge, every time any issue comes we have to open a case with HPE for performance report and fight with application team to make them understand storage is working fine. After deploying STOR2RRD it really provides a capacity overview, utilization of CPG, IO utilization, etc and it really helps us to resolve many issues.

HPE 3 PAR With VMware Virtual Volumes (VVols)

ارسال شده توسط admin | در دسته بندی Uncategorized

HPE 3 PAR With VMware Virtual Volumes (VVols)

 

VVols is  was a new storage architecture introduced in vSphere 6 and further enhanced with vSphere 6.5. HPE is a key design partner with VMware who selected HPE 3PAR StoreServ as the Fibre Channel (FC) reference platform for VMware’s engineering team. HPE 3PAR StoreServ provides a tightly integrated experience that does not require an additional plug-in or software piece to enable VVols and to support VMware’s VASA 3.0 specification. HPE 3PAR delivers unique capabilities, like ASIC-based Zero Detect for space reclamation and tiered snapshots, which can be assigned on a per-VM basis through VMware’s Storage Policy Based Management (SPBM).VVols eliminate the need to provision large datastores (LUNs) for VMFS volumes; storage provisioning now happens automatically on a per-VM basis. Each VM is assigned its own unique VVols, which is equivalent to a traditional storage LUN. With the tight integration with HPE 3PAR StoreServ Storage, customers will be able to deploy VVols, in parallel with VMware’s Virtual Machine File System (VMFS) where necessary. VVols introduces two big benefits: (1) VM-level granularity by introducing a one-to-one mapping of VMs to storage volumes, and (2) support for VMware’s Storage Policy Based Management (SPBM) to simplify storage management and automate storage provisioning and space reclamation. Before the introduction of VVols, storage arrays primarily integrated with vSphere at the datastore level using VMware’s VMFS.Moving forward, users can choose to use VMFS or VVols (or both), with VVols offering more advanced capabilities.

Comparison Between Tradition VMFS  Datastore and VVols

Architecture overview of VVols on HPE 3PAR

VMware Virtual Volumes with HPE 3PAR StoreServ Storage changes the storage architecture of vSphere from LUN-centric to VM-centric and allows storage arrays to become VM-aware. HPE 3PAR StoreServ integration with VVols shifts many common storage operations from the
vSphere host to the HPE 3PAR StoreServ array and enables the VMware vSphere VASA client to do the following:

 

• Dynamically create and manage HPE 3PAR StoreServ volumes
• Create, snapshot, clone, and delete HPE 3PAR StoreServ array volumes
• Discover HPE 3PAR StoreServ storage capabilities available for VVols
• Discover compliance issues with requested capabilities for VVols
• Automatically reclaim space when VMs are deleted or moved

The technology shift from a SCSI LUN-based model to an object-based model is the core difference introduced with vSphere 6 and VVols. VVols are object storage access, different from traditional block storage (LUN). Instead of the traditional approach of simply presenting a LUN (a linear range of Logical Block Addresses [LBAs]), vSphere 6 now manages data placement and access, giving the HPE 3PAR StoreServ Storage visibility into what LBAs correspond to objects such as a VMDK, configuration, swap, or clone.

VVols with the VASA Provider providing control path and the Storage Container on HPE 3PAR StoreServ Storage

HPE 3PAR StoreServ Storage supported features with VVols

The following HPE 3PAR features are supported with VVols

• Array-based snapshots
• Space reclamation (UNMAP)
• Array-based thin provisioning
• Thin deduplication
• Array-based replication
• Auto Zero Detect
• Adaptive flash cache

Each of the features listed above are resource intensive when performed by the host. By shifting them to the storage array using VVols, they are performed faster and more efficiently and help to increase available host resources.

For VVols replication – HPE 3PAR StoreServ and VMware VVols Replication Implementation Guide

Note :-
VMware VVols 2.0 (VASA 3.0) was released as part of vSphere 6.5, which is supported for HPE 3PAR OS 3.3.1 and higher and includes support for array based replication. VVols eliminate the need to provision large datastores for ESXi hosts, and offer more flexibility in managing storage
associated with virtual machines.

HPE 3 PAR With VMware VAAI (VSphere Storage APIs For Array Integration)

ارسال شده توسط admin | در دسته بندی Uncategorized

HPE 3 PAR With VMware VAAI (VSphere Storage APIs For Array Integration)

 

VAAI (vSphere Storage APIs for Array Integration) The vSphere Storage APIs are a set of technologies and interfaces that enable vSphere to leverage storage resources to deliver the efficiency, control, and ease of customization that clients demand of their virtual environment. The vSphere Storage APIs for Array Integration (VAAI) is one of these technologies. Under the VAAI initiative, APIs have been introduced to improve performance, resource utilization, and scalability by leveraging more efficient array-based operations.

vSphere 5 and 6 provide enhanced support for the T10 SCSI standard without the need to install a plug-in, enabling vSphere to directly utilize more advanced features of the storage array. Native T10 support is built into HPE 3PAR OS 3.1.1 and greater, allowing the ESXi host to communicate directly to HPE 3PAR StoreServ Storage without a VAAI plug-in.

Some of the important hardware primitives that VAAI enables are documented below:

Hardware Assisted Locking eliminates SCSI reservation contention by providing a fast, fine-grained locking mechanism. The ATS (“Atomic Test and Set”) command verifies that a block of metadata is what is expected (test) and then replaces it with an updated block (set) in a single, atomic operation. Using this command, the ESXi host can lock a portion of a LUN related to a single VM instead of locking the whole LUN as seen inFigure 9, thereby allowing other VMs on the same LUN to continue operating normally. The implementation of ATS on HPE 3PAR StoreServ Storage arrays uses the HPE 3PAR StoreServ ASIC to further improve performance. The combination of ATS and the HPE 3PAR StoreServ ASIC allows an increase in VM density per LUN and greater scalability for vSphere deployments.

Fast Copy uses the XCOPY command to improve the performance of common storage operations, such as VM cloning and Storage vMotion,by performing large data movement operations directly within the storage array. By not requiring each block to make a round-trip to the host,the time required for these operations is significantly reduced and storage network traffic minimized. When combined with HPE 3PAR Thin Persistence Software, drive I/O and storage capacity can also be reduced since blocks of zeros are not written due to the array’s Zero Detect capability, which is integrated into the HPE 3PAR StoreServ ASIC.Block Zeroing uses the standard SCSI command WRITE_SAME to offload large, block-level write operations of zeros from the host to the storage array. Block zeroing improves host performance and efficiency when allocating or extending Eager Zeroed Thick (EZT) virtual disks, or on initial access to a block on a non-EZT virtual disk. When combined with built-in Zero Detect and EZT virtual disks, storage array bandwidth, disk I/O bandwidth, and disk consumption is minimized. Initializing EZT virtual disks in seconds rather than minutes eliminates the tradeoff between fast VM creation and more predictable run-time performance

HPE 3PAR storage system supports VAAI using the “esxcli storage core device list” command

VAAI UNMAP command

Note
With vSphere 6.5, UNMAP commands may be issued by the guest OS (with the restrictions listed below), and no CLI operations are necessary to reclaim space when these conditions are met.

UNMAP is a SCSI primitive that allows VMFS to communicate to the storage target that certain blocks are no longer used on a LUN backing a datastore. Using the UNMAP command, vSphere can issue a command to the storage array to deallocate blocks of storage freed by vSphere,for example from a deletion of a VM, and return it to the storage array’s resource pool without the involvement of a storage administrator.
For vSphere 6, it is now possible for a guest OS to issue an UNMAP command to reclaim space. There are several prerequisites that must be metto allow UNMAP to run:

• The VMDK for the VM must be thin provisioned.
• The VM hardware version must be 11 (ESXi 6.0).
• The ESXi host advanced setting EnableBlockDelete must be set to 1.
• The guest OS must be able to identify the disk as thin.

Note : Windows 2008 and above is able to detect that the disk is thin provisioned.
SPC-4 SCSI command support was added in vSphere 6.5, allowing UNMAP commands to work with compatible Linux guest filesystems.UNMAP priority can be configured via the GUI or CLI: esxcli storage VMFS reclaim configuration set

HP StoreVirtual Multi-Path Extension Module (MEM) For VSphere

With the release of LeftHand OS 12.0, HP have introduced a Multi-Path Extension Module to replace the previously recommended path selection policy being ‘Round Robin’ and Storage Array Type Plugin VMW_SATP_DEFAULT_AA .By default Round Robin would send 1,000 I/O down each path , Reference –  Verify Mutilpath Policy IOPS  .

HP StoreVirtual Multipathing Extension Module (MEM) for VMware vSphere – Reduce latency and improve performance in VMware vSphere environments. The MEM also optimizes data-path traffic in multi-site (or stretch-cluster) configurations .

Download MEM for vSphere 6.5

Here we explains with a example of 2 nodes cluster .

we have two cluster nodes, A and B. When the first volume is created it is ‘owned by a master node’ in this case ‘node A’.  When the second volume is created it is owned by ‘node B and so on, as shown below.

  • Volume 1 – Node A
  • Volume 2 – Node B
  • Volume 3 – Node A
  • Volume 4 – Node B

Using the recommended bonding method of ‘Adaptive Load Balancing’ SCSI read and write commands are issued on all NIC’s in the bond which can result in data being accessed from a non-authoritative node, which means a trip across the network to the authoritative node.

This was rather inefficient and meant that random reads (which are served from disk) could be accessed from a non-authoritative node.  This is where the StoreVirtual Multi-Path Extension Module (MEM) steps in.  It has knowledge on where the data resides and ensures that all:

  • Read I/O’s are always serviced by the storage node that holds the authoritative data.
  • Write I/O’s are always serviced by the storage node that receives a mirror copy of the data ensuring data integrity.  Remaining copies are then forwarded to the remaining storage nodes.

This results in the following data flow architecture.

VMFocus HP StoreVirtual MEM Diagram

The installation guide for HP StoreVirtual Multipathing Deployment Guide is fairly straight forward.  The only issue I ran into was ‘could not find trusted signer’ when trying to install the vib.

This was resolved by adding –no-sig-check to the end of the command esxcli software vib install -v /HPMEM.vib –no-sig-check

Once installed, you will need to change the path selection policy for your datastores to HP_PSP_LH

HPE 3PAR StoreServ Block Storage Concepts And Terminology

ارسال شده توسط admin | در دسته بندی Uncategorized

HPE 3PAR StoreServ Block Storage Concepts And Terminology

 

The HPE 3PAR StoreServ array is comprised of the following logical data layers

• Physical disks (PDs)
• Chunklets
• Logical disks (LDs)
• Common provisioning groups (CPGs)
• Virtual volumes (VVs)

The relationship between system data layers is illustrated in Figure 1. Each layer is created from elements of the layer above. Chunklets are drawn from physical disks. Logical disks are created from groups of chunklets. Common provisioning groups are groups of logical disks. And
virtual volumes use storage space provided by CPGs. The virtual volumes are exported to hosts and are the only data layer visible to hosts.

Physical disks

A physical disk is a hard drive (spinning media or Solid State Drive) located in an HPE 3PAR StoreServ drive enclosure.

Cage

Cage is a legacy HPE 3PAR term and is interchangeable with “Drive Enclosure,” “Enclosure” and “Drive Shelf.”

Chunklets

Physical disks are divided into chunklets. Each chunklet occupies physically contiguous space on an FC, NL or SSD disk. On all current HPE 3PAR StoreServ all chunklets are 1 GB. Chunklets are automatically created by the HPE 3PAR OS, and they are used to create logical disks. A chunklet is assigned to only one logical disk.

Logical disks

A logical disk is a collection of chunklets arranged as rows of RAID sets. Each RAID set is made up of chunklets from different physical disks.Logical disks are pooled together in common provisioning groups, which allocate space to virtual volumes.The underlying logical disks are automatically created by the HPE 3PAR OS when you create VVs. The RAID type, space allocation, growth increments, and other logical disk parameters are specified when you create a CPG or can be modified later. The HPE 3PAR StoreServ supportthe following RAID types:

• RAID 1 aka RAID 1+0
• RAID 5 aka RAID 50 (must be enabled from the CLI for NL or FC drives)
• RAID Multi-Parity (MP) aka RAID 6 or double parity
• RAID 0 (must be enabled from the CLI and provides no data protection from failed drives).

Virtual Copy

Virtual Copy is a legacy HPE 3PAR term and is interchangeable with “Snapshot.”

CPGs (Common provisioning groups)

A CPG is a template for the creation of logical disks that allocate space to virtual volumes on demand. A CPG allows up to 65,536 virtual volumes to share a CPG’s assigned resources. You can create fully provisioned virtual volumes (FPVVs), Thinly Deduped Virtual Volumes (TDVVs) and
Compressed VVs that draw space from a CPG’s logical disks. It is important to note that if no volumes of any type have been created in a CPG, it consumes no space.

VVs (Virtual volumes)

VVs (Virtual volumes) draw their resources from the LDs in CPGs and are exported as LUNs (Logical Unit Numbers) to hosts. Virtual volumesare the only data layer visible to the hosts. You can create clones (previously known as full copies) or snapshots (previously known as virtual
copies) of virtual volumes. Clones remain available if the original base volume becomes unavailable. VVs can be created using the CPGs created at installation time or user defined CPGs.

Exporting virtual volumes

For a host to see a VV, the volume must be exported as a LUN. Volumes are exported by creating VV-LUN pairings (VLUNs) on the system.When you create VLUNs, the system produces both VLUN templates that establish export rules, and active VLUNs that the host sees as LUNs as attached disk devices. A VLUN will be created for each path available to the host for each VV exported.

FPVVs (Fully provisioned virtual volumes)

A FPVV virtual volume is a volume that uses logical disks that belong to a CPG. Unlike TPVVs or TDVVs, fully provisioned virtual volumes have a set amount of user space that is allocated for user data. The fully provisioned volume size is allocated and consumed at the time of provisioning, size limits range from 256 MB to 64 TB (Compressed and Dedupe VVs have a maximum size of 16 TiB). The volume size can be increased at any time (provided free space is available) up to the maximum 64 TiB size without any downtime however, the VV size cannot be decreased below the initial allocation.

TPVVs (Thinly provisioned virtual volumes)

A TPVV is a volume that uses logical disks that belong to a CPG. TPVVs, TDVVs, or DECO VVs (deduped and compressed) associated with the same CPG draw space from those CPGs’ LDs as needed, allocating space on demand in 16 KiB increments for each VV. As the volumes that draw
space from the CPGs’ LDs (including compressed and deduped) require additional storage the HPE 3PAR OS automatically creates additional logical disks or expands the size of existing LDs and adds them to the CPG until the CPG reaches a user-defined growth limit, if one has been set,
or the system runs out of space.

TDVVs (Thinly deduped provisioned virtual volumes)

In addition to the features and functionality of TPVVs; TDVVs go through an additional process before allocating space on a disk. All data writes with a block size 16 KiB or greater have a unique hash generated and the resulting value is compared to a hash lookup table to determine if the
data has already been stored. If the data is a duplicate of existing data, an entry is added to the destination volume’s lookup table but no data is written. Otherwise it is written to disk. For more information on this, refer to the HPE 3PAR Thin Technologies white paper located here.

Clones (also known as Physical Copies)

A clone duplicates all the data from a base volume to a destination volume. The base volume is the original volume that is copied to the destination volume. The clone on the destination volume remains available if the original base volume becomes unavailable.A clone requires the destination volume have usable capacity equal to or greater than the usable capacity of the base volume being cloned. As of HPE 3PAR OS 3.2.1 the clone can be exported immediately after creation, while the data copy continues in the background.

Snapshots (also known as Virtual Copy)

Unlike a clone, which is a block for block duplicate of an entire volume, snapshots preserve a bitmap of a VV at a particular point in time.Updates to VVs are written to SD (Snap Data) space and the bitmap (Snap Admin space) of the VV.

Snapshots for FPVVs, TPVVs, dedupe compressed and DECO clones and other snapshots are created using copy-on-write techniques available(aka Virtual Copy) snapshots for TDVVs are created using ROW (Redirect On Write). Hundreds of snapshots of each virtual volume can becreated assuming that there is sufficient storage space available. It is worth noting that snapshots do not consume any space unless data on the base volume has been updated and the original data copied to the SD (Snap Data) space. Changed data is copied only once regardless of thenumber of snapshots taken. Snapshots are particularly useful for test/dev environments as they can be created in seconds and exported while not effecting production data. Also, testers and developers can be granted the ability to create snapshots while not having any ther administrative privileges, lowering administration requirements (see the HPE 3PAR CLI guide for correct usage for granting the updatevv privilege). Snapshots can now be updated without the requirement to unexport and re-export the VV. For more information on snapshot/Virtual Copy technologies refer to the white paper here .

File Provisioning Group

A File Provisioning Group (FPG) is an instance of the HPE intellectual property Adaptive File System. It controls how files are stored and retrieved. Each FPG is transparently constructed from one or multiple Virtual Volumes (VVs) and is the unit for replication and disaster recovery for File Persona Software. There are up to 16 FPGs supported on a node pair.

Virtual File Server

A Virtual File Server (VFS) is conceptually like a server; as such it presents virtual IP addresses to clients, participates in User Authentication Services and can have properties for such characteristics as user/group Quota Management and Antivirus policies.

File Stores

File Stores are the slice of a VFS and FPG where snapshots are taken, capacity Quota Management can be performed, and Antivirus Scan Services policies customized.

File Shares

File Shares are what provide data access to clients via SMB, NFS, and the Object Access API, subject to the share permissions applied to them

HP INFOSIGHT COMES TO 3PAR AND GETS AI

HP INFOSIGHT COMES TO 3PAR AND GETS AI

 

HPE Discover is due to kick off in Madrid next week and HPE have continued their current tradition of releasing all the big news before the show.

I’ve been lucky enough to attend a few Discovers now and I have noticed some interesting trends in the type of announcements. Previously it was all about physical products, what were the newest models what were the hardware innovations in these products. This year all the key announcements are software based and focus on enhancing user experience.

INFOSIGHT

Ironically for many years whilst storage systems stored lots of data on them, the data analytics for managing the systems was somewhat lacklustre. Data was gathered from these systems and sent back to base but it was a simple affair which alerted you to failed components such as a disk. Nimble Storage saw a unique opportunity in this area and acted upon it by developing their class leading InfoSight analytics platform.

Like other storage systems Nimble sends data home, but where things get different are in the breadth of statistics collected and what happens to them once they are sent back to base. Nimble realized that by taking the data from their entire install base and then using machine learning against this, insights could be developed to predict issues before they even occur. I have two impressive stats to back this up; 86% of issues are being detected and fixed before the customer even knows about it and 54% of issues resolved are outside of storage. This ability to diagnose issues outside of storage closed what Nimble termed the app data gap.

INFOSIGHT ADDS AI

The first major announcement from HPE Discover is that InfoSight is now able to utilise AI. We discussed previously how Nimble had built a cloud analytics platform from all the data that was being sent home. InfoSight was able to analyse and predict future patterns using machine learning. The introduction of AI allows this to be taken to the next level by enabling more complex issues to be automatically addressed.

Recommendations will go beyond simple problem prevention to include resource optimisations, ensuring you getting the most from your system. Again this is not just for the storage itself but the whole ecosystem for example it may recommend the movement of a VM to a different volume. The name of this new AI functionality “AI recommendation engine” clearly indicates its future direction for further automation.

You can see more about the AI capabilities in the video below:

INFOSIGHT COMES TO 3PAR

The second piece of InfoSight news is that it is coming to 3PAR. 3PAR has always had a rich amount of telemetry being sent home but up until now it has arguably not been fully utilised. But of course lots of data without the tools to interpret and act upon it is not much use and this is what InfoSight has enabled.

3PAR InfoSight

Like the Nimble system before it InfoSight on 3PAR will not just report on the storage itself but down to the application level. To benefit from InfoSight on 3PAR you need to be running 3PAR OS 3.3.1 have an active support contract and of course have your 3PAR configured to dial home.

WRAP-UP

The Nimble AI recommendations and 3PAR InfoSight are both free for customers with a active support contract and are expected in January 2018

I’m sure that the HPE engineering team are working at a furious pace to get InfoSight out across to as many products, as quickly as possible. It’s clear to see that improved analytics would not only reduce operational issues but that the introduction of AI driven resource recommendations will drive the move to an automated data centre. It seems obvious that automated resource allocation recommendations would fit in nicely with Synergy where the ability to spin up and down workloads dynamically could then be orchestrated intelligently.

HPE StoreVirtual VSA Software & Components

ارسال شده توسط admin | در دسته بندی Uncategorized

HPE StoreVirtual VSA Software & Components

 

HPE StoreVirtual VSA Software transforms your server’s internal or direct-attached storage into a fully-featured shared storage array without the cost and complexity associated with dedicated storage. StoreVirtual VSA is a virtual storage appliance optimized for VMware vSphere.  StoreVirtual VSA creates a virtual array within your application server and scales as storage needs evolve, delivering a comprehensive enterprise-class feature set that can be managed by an IT generalist. The ability to use internal storage within your environment greatly increases storage utilization. The unique scale-out architecture offers the ability to add storage capacity on-the-fly without compromising performance. Its built-in high availability and disaster recovery features ensure business continuity for the entire virtual environment.

Simple and Flexible to Manage

Enjoy all the benefits of traditional SAN storage without a dedicated storage device. HPE StoreVirtual VSA Software allows you to build enterprise level, highly available, shared storage functionality into your server infrastructure to deliver lower cost of ownership and superior ease of management.

All StoreVirtual VSA nodes in your environment, onsite or across multiple sites, can be managed from the Centralized Management Console (CMC). The CMC features a simple, built-in best practice analyzer and easy-to-use update process. Add more internal storage capacity to the cluster by simply adding servers with StoreVirtual VSA installed. No external storage device required: Create shared storage out of internal or external disk capacity (DAS, SAN); (FC or iSCSI).

Snapshots provide instant, point-in-time volume copies that are readable, writeable, and mountable for use by applications and backup software. Avoid data loss of any single component in a storage node with StoreVirtual’s multi-fault protection. Remote Copy enables centralized backup and disaster recovery on a per-volume basis and leverages application integrated snapshots for faster recovery.

Network RAID stripes and protects multiple copies of data across a cluster of storage nodes, eliminating any single point of failure in the StoreVirtual array. Applications have continuous data availability in the event of a disk, controller, storage node, power, network, or site failure. Create availability zones within your environment across racks, rooms, buildings, and cities and provide seamless application high availability with transparent failover and failback across zones—automatically.

Increase Scalability and Storage Efficiency

Use StoreVirtual VSA with solid-state drives (SSDs) to provide a high-performance storage solution in your environment. Create an all-flash tier for maximum performance or use a lower cost alternative with StoreVirtual Adaptive Optimization to create automated tiers with an optimized amount of SSDs. Maximize storage utilization by deploying high-performance arrays at the main site and cost-effective appliances at remote sites. Use management plug-ins for VMware vCenter. Lower storage costs and achieve high availability with as few as two nodes that easily scale from within Scale-out storage architecture allows the consolidation of internal and external disks into a pool of shared storage. All available capacity and performance is aggregated and accessible to every volume in the cluster. As storage needs grow, the cluster scales out linearly while remaining online.

Components

Built on an open-standards platform, StoreVirtual VSA software can run on any modern x86-based hardware in VMware vSphere, Microsoft Hyper-V, and Linux KVM hypervisors.

StoreVirtual technology components include targets (storage systems and storage clusters) in a networked infrastructure. Servers and virtual machines act as initiators with access to the shared storage. The LeftHand OS leverages industry-standard iSCSI protocol over Ethernet to provide block-based storage to application servers on the network. And for high availability it uses fail over manager or Quorum Disk’s.

HPE Store Virtual Software

HP StoreVirtual VSA is a proper virtual storage appliance (VSA) suppor

ted in production environments providing block-based storage via iSCSI.

A VSA is a virtual appliance deployed in a VMware environment which aggregates and abstracts physical underlying storage in a common storage pool which will be presented to the hypervisor and can be used to store virtual machine disks and related files.

StoreVirtual VSA can use both existing VMFS datastores and RDM (raw LUNs) to store data and it can be configured to support sub-volume tiering to move data chunks across tiers. StoreVirtual VSA as the “physical” HP StoreVirtual counterpart is a scale-out solution, this means that if you need to increase storage capacity, resilience or performance other StoreVirtual VSA nodes (i.e. virtual appliances) can be deployed.

Storage System or Storage Node

A storage node is a server that virtualizes its direct-attached storage. In the case of StoreVirtual nodes, each one includes controller functionality—no external controllers needed. Storage nodes require minimal user configuration to bring them online as available systems within the Centralized Management Console (CMC).

StoreVirtual Cluster

Multiple StoreVirtual VSAs running on multiple servers create a scalable pool of storage with the ability to make data highly available. We can aggregate two or more storage nodes into a flexible pool of storage, called a storage cluster.

Multiple clusters can be aggregated together into management groups. Volumes, clusters and management groups within the shared storage architecture can be managed centrally through a single console.

Management groups

A Management Group is a logical container which allow the management of one or more HP StoreVirtual VSAs, Clusters and Volumes. Management group will have credentials set on the configuration time .And these credentials will be used for any management task of any HP StoreVirtual belonging to this specific Management Group.

FOM & Quorum Disk

The Failover Manager (FOM) is designed to provide automated and transparent failover capability. For fault tolerance in a single-site configuration, the FOM runs as a virtual appliance in either a VMware vSphere, Microsoft Hyper-V Server, or Linux KVM environment, and must be installed on storage that is not provided by

the StoreVirtual installation it is protecting.

The FOM participates in the management group as a manager; however, it performs quorum operations only, it does not perform data movement operations. It is especially useful in a multi-site stretch cluster to manage quorum for the multi-site configuration without requiring additional storage systems to act as managers in the sites. For each management group, the StoreVirtual Management Group Wizard will set up at least three management devices at each site. FOM manages latency and bandwidth across these devices, continually checking for data availability by comparing one online node against another.

If a node should fail, FOM will discover a discrepancy between the two online nodes and the one offline node – at which point it will notify the administrator. This process requires at least three devices, with at least two devices active and aware at any given time to check the system for reasonableness: if one node fails, and a second node remains online, the FOM will rely on the third node to maintain quorum, acting as a “witness” to attest that the second node is a reliable source for data.

In smaller environments with only two storage nodes and no third device available to provide quorum, we can implement with any one of the below two option.

  1. Supply a third node onsite with StoreVirtual VSA installed and use FOM to maintain quorum
  2. Set up 2-Node Quorum on a shared disk, using LeftHand OS 12.5 or later versions

StoreVirtual 2-Node Quorum is a mechanism developed to ensure high availability and transparent failover between 2-node management groups in any number of satellite sites, such as remote offices or retail stores. A cost-effective, low-bandwidth alternative to the FOM, the feature does not require a virtual machine in that site, relying instead on a centralized Quorum Witness in the form of an NFSv3 file share as the tie-breaker between two storage nodes as shown below .

Quorum Witness uses a shared disk to determine which of the two nodes should be considered a reliable resource in the event of a failure. The shared disk is an NFS share that both nodes in the management group can access.

Volume

It is basically a shared volume crated with help of Network Raid protection. Network RAID (so the data protection level) can be set per volume. So multiple volumes can co-exist on a StoreVirtual cluster with different Network RAID levels. This Volume can be accessed through iSCSI protocol.

Network RAID protection which basically spreads data between different VSAs as the common RAID spreads data across different physical disks within the same array.

CMC (HP StoreVirtual Centralized Management Console)

All StoreVirtual VSA nodes in your environment, onsite or across multiple sites, can be managed from the Centralized Management Console (CMC). The CMC features a simple, built-in best practice analyzer and easy-to-use update process
