Hi everyone, we have some great news for VMware SRM 4.1.x users.
The new IBM XIV Adapter for VMware vCenter SRM 4.1.x was released!
The IBM XIV Adapter version 4.1.0 adds support for XIV's GEN3 systems, and also fixes a couple of bugs.
So if you are using SRM 4.1 - you can now use it with both XIV GEN2 (microcode version 10.2.x) and XIV GEN3 (microcode version 11.x)!
You can download the IBM XIV adapter software package from the SRM 4.1.2 download page (after clicking the View Downloads button, the IBM XIV adapter is listed on the page).
Feel free to ask us any question.

The new version adds the following enhancements for XIV users:
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).
These enhancements also apply to other IBM storage systems that the plug-in supports. In addition, version 3.0.0 introduces support for IBM Storwize V7000 Unified and IBM Scale Out Network Attached Storage (SONAS) as well as various bug fixes. You can check out the release notes for more details.
After you’ve heard all that, you can now go ahead and download the IBM Storage Management Console for VMware vCenter version 3.0.0 along with its documentation from the IBM Fix Central.
We’d love to hear your thoughts and comments, so please share them with us!
We are happy to announce the release of an updated OpenStack Cinder driver for IBM Spectrum Virtualize, Storwize Family and FlashSystem V9000. This release complies with OpenStack Liberty specifications, emphasizing IBM's continuous commitment to making the cutting-edge OpenStack features available for IBM storage customers.
Another change is the enabling or disabling the fast format option during thick volume creation. As some volume operations are disabled until fast format is completed, the customer can now skip the fast format, when creating a thick volume. This makes the volume operational immediately after its creation.
Version 7.6 of IBM Spectrum Virtualize and Storwize Family will be supported after its release with no additional Cinder driver code change.
We are excited to announce release of IBM XIV SRA 2.1.0 that is compatible with VMware Site Recovery Manager 5.0.
About SRM 5.0:
Site Recovery Manager 5.0 includes three major additions to the workflow capabilities:
About IBM XIV SRA 2.1.0 with VMware SRM 5.0:
The IBM XIV SRA extends SRM capabilities and allows it to seamlessly employ XIV replication and mirroring as part of the SRM comprehensive Disaster Recovery Planning (DRP) solution.
Using the IBM XIV SRA, VMware administrators can automate the failover of an XIV system at the primary SRM site to an XIV system at a recovery (secondary) SRM site. Immediately upon a failover, the ESX/ESXi servers at the secondary SRM site start using the replicated datastores on the mirrored volumes of the secondary XIV system.
That's great ! But where can I get It ?
It's already available at the VMware download page of SRM 5.0.1 (You can click on the "Show Details" link inside the "Components" section to reveal the list of SRA components with IBM XIV SRA included)
We would love to hear from you, please leave you questions and comments below.

We worked hard and it finally happened! Our own IBM XIV Storage Replication Adapter (SRA), version 2.2.2 is fully certified to operate with the following releases of the VMware vCenter Site Recovery Manager: 5.5, 5.5 Update1, 5.8, 6.0 and 6.1. Although this version is considered a minor release, making the SRA work with all the latest SRM versions was a challenging goal, involving a battery of compatibility tests and closely tied cooperation between the IBM and VMware interoperability teams.
Time to do some XIV mirroring :).
We are proud to announce that the IBM XIV Host Attachment Kit has been recently upgraded to a new version - 2.5.0. This release brings support for XIV microcode version 11.6.x, IBM Spectrum Accelerate 11.5.1.x, and RHEL 7.1. In addition, this version introduces a hot feature - the host-side acceleration (HSA) for improved iSCSI communication between Spectrum Accelerate and a host.
Another change is a deprecation of the -L option of the xiv_iscsi_admin and xiv_fc_admin commands, reserving the ability to list the attached storage devices for the xiv_syslist -L command only.

It's been a long 9 months since the release of the IBM XIV HAK 2.2.0 and we're back with a new exciting release - IBM XIV HAK 2.3.0 .
Example 1: Cleaning up a stale device
The next feature is also a response to customers needs. People using Veritas Dynamic Multi-Pathing (DMP) had issues running xiv_attach, as it always configured and initiated the native multipath framework. Two multipath frameworks on the same host is like having two managers not speaking to each other, each pulling in another direction.
Example 2: xiv_attach in presence of Veritas DMP
A third feature relates to the new release of XIV Microcode 11.5 and a feature we call Multi-Tenancy. Let's say you have two companies working on the same storage, each with it's own data that should never ever get to the other company. The storage can be divided into domains so that each is maintained by separate people, unaware of each others work. From the point of view of the storage administrator running xiv_attach or xiv_iscsi/fc_admin, he just uses his credentials to connect to the storage and everything behaves as expected. In case a user is able to see more than one domain (e.g. in case of domain per department) he is able to specify the domain the host should be using via a flag in the xiv_iscsi/fc_admin command line.

It's been 4 months since the release of the IBM XIV HAK 2.1.0 and we're back with a new release - IBM XIV HAK 2.2.0.
So what's new in this release? We won't bother you with all the changes and fixes - you can find the detailed list in the Release Notes document coupled with the software package. We would however like to point out that the new release supports a new operating system - Microsoft Windows Server 2012 R2 - an important step by itself. But the main feature of this release is related to xiv_host_profiler and the way 'analyze' operates.
Since the addition of xiv_host_profiler utility in the HAK 2.0.0 release, we see growing interest in this application. Administrators want to know that the system they are working on is configured right and how to improve their settings. Makes sense, doesn't it?
The problem was that the analysis was based on the latest microcode released, and this is not the common situation in the field. Following the famous "if it ain't broken don't fix it" approach, upgrading the storage microcode is not done as frequent as we'd like it to happen. So for example, although a microcode version 11.1.x is used, the administrator would get the analysis results of 11.2.0 (HAK 2.0.0) or 11.3.0 (HAK 2.1.0) which have different rules.
To solve this problem in the new HAK release we collect the microcode versions of the connected XIV storage and the analysis is based on these versions. So if your host is connected to 10.2.4 or to 11.2.0 or 11.3.0, you can expect different results. In the following example you can see the same host running against two different microcode versions with two different analysis results.
And what about testing your configuration against a different microcode version? For example, if you have an XIV system running microcode 11.2.0 and you want to upgrade to 11.4.0 - will your host configurations still be valid? So we added an option for the user to specify the microcode version he is interested in.
