It would be quite accurate to state that virtualization technology today is gaining momentum, allowing companies to lower their total cost of ownership (TCO), reduce their datacenter footprint, ensure faster server provisioning, and more. However, implementing server virtualization without accounting for the storage element could cause problems, such as uneven resource sharing, as well as degradation in performance and data integrity.

Various IBM storage systems provide virtual enterprise storage for virtual servers. Specifically, the IBM storage systems work in concert with the following VMware virtualization platforms, standards, and environments:

• VMware vSphere Hypervisor (ESXi)
• VMware vSphere Web Client (vWC)
• VMware vSphere APIs for Storage Awareness (VASA)
• VMware vSphere Virtual Volumes (VVols)
• VMware vRealize Orchestrator (vRO)
• VMware vRealize Operations Manager (vROPs)

To leverage, manage, and centralize this entire connectivity from a single interface, the IBM Spectrum Control Base Edition (SCBE) software package enables a simplified deployment and more efficient integration of different IBM storage systems (also referred to as storage arrays) and the VMware vCloud suite.

IBM Storage with VMware vSphere Web Client (vWC)

Without SCBE, when VMware administrators run out of disk space and request more space from the storage administrators, the storage increase provisioning may take quite a long time to implement and complete. This occurs mostly because of miscellaneous enterprise “red tape” procedures and processes. Moreover, before provisioning additional storage, storage administrators must fully understand the specific needs of the VMware administrators, then find available space on the attached storage systems, create and map storage volumes, and so on.

The SCBE solution uses an abstraction layer through a storage service and pre-defined sets of storage resources (pools) and capabilities (compression, encryption, etc). The services are prepared by storage administrators and provided for VMware administrators for fast and easy self-provisioning whenever required.

IBM Storage with VMware VASA and virtual volumes (VVols)

In the traditional data storage implementations, storage administrators manage multiple VMFS-based datastores with up to 7 TB in size and without explicit indication of storage capabilities. In addition, all VM snapshot and replication procedures are performed on the ESXi server side, without leveraging much faster hardware-based storage system capabilities.

The virtual volume (VVol) approach eliminates the VM granularity by introducing a single large VVol-based datastore with dynamic definition of storage policies (services) for provisioning storage resources exactly according to application requirements.

IBM Storage with VMware vRealize Orchestrator (vRO)

With the IBM Storage Plug-in for VMware vRealize Orchestrator, VMware administrators can include storage discovery and provisioning into their workflows. The plug-in allows issuing automated workflows with storage volumes that are attached to the vRealize Orchestrator server, eliminating the need for manual storage provisioning by storage administrators.

IBM Storage with VMware vRealize Operations Manager (vROps)

Monitoring IBM storage systems without VMware vROPs is limited to information about their physical objects. When using the IBM Storage Management Pack for vROPs, the storage systems are integrated into global monitoring network at the network operations center (NOC). The systems appear on vROPs dashboards, presenting in detail all relations between storage system objects (disks, ports, volumes etc) and VMware objects (datastores and VMs).

You may ask: version 3.2.0 is already available so soon? Our answer: yes. Although earlier this month we released IBM Spectrum Control Base Edition version 3.1.1, version 3.2.0 is a genuine breakthrough, bringing support for the Microsoft PowerShell automation tool, in addition to our already well-established VMware cloud integration offerings. The new IBM Storage Automation Plug-in for PowerShell provides 'cmdlets' for automated storage management, including provisioning, host mapping, volume expansion, and other storage-related tasks.

For the first time, you can download the plug-in from the Microsoft PowerShell Gallery website at: https://www.powershellgallery.com/packages/SpectrumControlBase-Client. For further details about this new version, including fixes and an experimental Flocker feature (might not be included in future versions), check out the IBM Spectrum Control Base Edition 3.2.0 release notes on IBM Knowledge Center at: https://ibm.biz/Bds7gK.

A new version of Spectrum Control Base Edition software (3.1.1) has been released. It replaces version 3.1.0 and brings support for the IBM FlashSystem A9000 and A9000R (12.0.3) storage capacity feature. In addition, it introduces a full compatibility with the current VMware vSphere Web Client Server requirements. For details about this new version, see the Spectrum Control Base Edition release notes on IBM Knowledge Center at  https://ibm.biz/BdswcP.

We are glad to announce the release of  Spectrum Control Base Edition (SCBE) 3.1.

This new version introduces the following improvements:

• Improved handling of VMware virtual volumes (VVols), allowing for multiple VVol-enabled services to reside on a single storage space. Also, a new resource attachment method is used to attach several storage resources from different storage systems to one service.
• Added the availability capability for a storage service, enabling the use of stretched clusters on IBM Virtualize Family systems.
• Added the Quality of Service (QoS) capability for the Spectrum Accelerate Family storage services, enabling the use of volumes or storage resources according to predefined service levels.
• VMware currency for vCenter, vWC, vRO, vROps
• Bug fixes

Spectrum Control Base Edition 3.1 can be downloaded from Fix Central:

We'd be glad to hear your feedback!

VMware administrator, provision new datastores for your applications yourself, using IBM Storage Enhancements for vSphere Web Client. Use abstracted storage services, provided by your storage administrator. The services are consistent with application requirements with extendable storage space and VVol support. IBM Storage Enhancements for vSphere Web Client come packaged with IBM Spectrum Control Base Edition, a nifty storage provisioning tool integrated with a variety of VMware solutions for automation, monitoring, orchestration and native support of VVols and VASA API. Check the solution overview on YouTube at https://youtu.be/tf-0LGABZK8.

To make this happen, IBM has teamed up with VMware, creating a better experience for administrators and end users. We are proud to be one of the first partners in VMware's Web Client Plug-in certification program.
Learn more about the VMware program here: http://vmw.re/1S2FF7B.

If you happen to be using one or more IBM storage systems that are serving your VMware environment, we invite you to check out our recently released ’IBM Storage Integration Server’, a software solution that consolidates all your IBM storage usage through a single backend deployment.

You can add your IBM storage arrays into the scope of IBM Storage Integration Server in just one step, by using your storage user credentials as shown in the following example from the web-based management interface: 

Once added, the arrays would be available to all supported solutions, without having to re-add each storage array separately for each solution or for any future supported solution.

This single integration server reduces the amount of management traffic and shares the queried storage information with all the supported solutions. The first release, version 1.1.0, introduces support for ‘IBM Storage Enhancements for VMware vSphere Web Client’ and for ‘IBM Storage Provider for VMware VASA’.

‘IBM Storage Enhancements for vSphere Web Client’ enables native visibility and provisioning of IBM storage volumes (LUNs) within VMware vSphere Web Client. These enhancements bring the value of the already known and acclaimed IBM Storage vCenter plug-in, formally known as ‘IBM Storage Management Console for VMware vCenter’, to the new web-based VMware vSphere Web Client, which allows the integration of multiple vCenter servers instead of one.

VMware administrators who were previously daunted by the thought of the complex task of connecting and utilizing storage resources through vSphere Web Client – can now be much more relaxed with the ability to easily create and manage storage volumes in delegated storage pools, which were attached by the storage administrators on the IBM Storage Integration Server side. 

‘IBM Storage Provider for VMware VASA’, previously a standalone plug-in, is now a feature of the IBM Storage Integration Server, adding the following enhancements:

·                     Supports the IBM Storwize family in addition to the existing IBM XIV support.

·                     Storage capabilities are automatically defined and assigned, eliminating the need for manual definition and assignment.

That’s about it, for now J

More to come soon!

• Multiple volume creation in one single operation: You can now create a few volumes together, instead of creating each volume separately. You can see how it's done in the example screenshots below, marked in a blue rectangle.
• Consistent volume names across the vSphere environment: In previous versions it was difficult to identify your volumes through VMware vSphere’s panels and wizards due to the long-form name given to them. For example, this is what your Add Storage wizard may have looked like:

But which Disk/LUN is the one I am looking for? Now when you create a volume, the name you provide is used as the VMware’s Disk/LUN name in the vSphere environment, making it much easier to view and manage.

For example, have a look at this ‘Creating 3 new volumes’ operation:  

The volume names in VMware’s “Add Storage” wizard are identical, allowing simple volume identification!

• Simple multipath policy enforcement: This feature enforces the multipath policy either per storage array or per single volume, overriding VMware's defaults.
  

  To set the policy for an entire XIV storage system, go to the IBM Storage tab, right click on the relevant storage system, choose Set Multipath Policy Enforcement, and then select the appropriate option:

  
   

From now on, for each new volume you create on the storage system, the IBM storage plug-in enforces the chosen MP policy. Alternatively, if you choose Disable Multipath Policy Enforcement, no MP policy is enforced  (in such a case, VMware’s default MP policy for the storage array will be in effect).

 

Just note that this feature is designed mostly for ESX/i versions 4.1 or earlier, where the default multipath policy set for the IBM XIV storage system was not Round Robin (RR). In ESXi 5.0 or later, the default is RR.

 

Let’s face it: even the most resilient, robust, and secure storage sites, located above ground or even underground, could potentially be exposed, in a certain degree, to all kinds of disasters that may temporarily or indefinitely halt the site operation. This could be an extreme weather condition or natural disaster (hurricane, tornado, earthquake, etc.), a prolonged and unplanned interruption of power supply (power grid or power station failure), an accident, act of war, cyberattack, and who knows what else – God forbid…

Enterprises that rely on non-stop, continuous, and unbreakable access to data, as well as on the ability to keep existing data integrity in parallel to on-going update/writing operations at the highest possible standards, must have disaster prevention and recovery mechanisms in place, ready to be used at any point in time.

Enterprise-class storage systems, such as IBM XIV Gen3, IBM FlashSystem A9000, and IBM FlashSystem A9000R, provide advanced site mirroring capabilities, either synchronous or asynchronous, including 3-site mirroring for XIV Gen3, and HyperSwap for FlashSystem A9000 and A9000R. These native underlying replication and high availability (HA) technologies allow these IBM storage systems to serve not only conventional hosts and clusters, but also virtual machines in VMware and Microsoft cloud environments, as well as OpenStack cloud nodes.

Virtual machines duplicates can be deployed at a secondary backup site, together with the backup storage systems to serve those sites.

• In a Microsoft Azure environment, automatic failover to the backup or primary site is natively supported by the storage system, by using Microsoft Azure Site Recovery.
• In a VMware environment, virtual machines can be recovered by using VMware Site Recovery Manager (SRM) together with the IBM Spectrum Accelerate Family Storage Replication Adapter (SRA), which also supports – starting from version 3.0.0 – HyperSwap operations.
• OpenStack high availability configurations are also supported.

For detailed information about employing HyperSwap for VMware and Microsoft environments, refer to the IBM Redpaper: ‘IBM HyperSwap for IBM FlashSystem A9000 and A9000R’. Additional data protection scenarios are described in this IBM Redpaper: ‘IBM FlashSystem A9000 and A9000R Business Continuity Solutions’.
