We are proud to announce that the IBM Storage Driver for OpenStack has been recently upgraded to a new version - 1.6.0. This version brings support for OpenStack Liberty release, as well as for DS8870 microcode version 7.5 SP3 and DS8880 version 8.01. In addition, this release introduces the XIV and Spectrum Accelerate support for the OpenStack consistency groups. It also brings in the RESTful API that replaced the Java-based ESSNI driver in DS8000 storage systems.

IBM Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service, version 4.11.0.
A new version of IBM Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service has been released. This is version 4.11.0, which introduces support for the following storage system microcodes:
Also, version 4.11.0 adds support for temporary (non-persistent) read/write access to a snapshot.
IBM Spectrum Control Base Edition has been upgraded to a new version - 2.2.1. This release replaces the previous version (2.2.0). It introduces support for the VMware virtual volume (VVols) and Storage Policy Based Management (SPBM) technologies for the storage systems that run the IBM Spectrum Virtualize software with microcode version 7.6.0. These are:
Additional changes include support for new data encryption method used by the Spectrum Virtualize software and ability for a storage resource attached to a VVol-enabled service to use other storage resources for VVol snapshots if it has reached its capacity.
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 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.
IBM Spectrum Control Base Edition continues its evolution with a new version - 2.2.0. This release brings support for VMware VASA 2.0 without virtual volumes for DS8870 7.5.x (using patch DS8870_REST_API_7.7.51.xx.zip) and adds support for IBM Spectrum Accelerate version 11.5.1.x.
Additional changes include ability to manage storage resources directly from the pool list per storage system or storage service, using the Spectrum Control Base GUI. Also, starting from version 2.2.0, DS8870 storage systems make use of the RESTful API client to simplify the Spectrum Control upgrade and installation procedures, eliminating the need for previously used JRE extension bin files.
In general, IBM Spectrum Control Base Edition became a more robust, use-friendly and fault-tolerant solution for managing multiple IBM storage platforms.

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.

We've just released the IBM Storage Driver for OpenStack v.1.3.0, get it
now while it's hot from the oven!
IBM Storage Driver for OpenStack v1.3.0 package now includes:
* OpenStack Havana Support (Including Volume migration)
* IBM DS8000 Storage System in addition to the IBM XIV Storage System
* In addition to Ubuntu 12.04 x64, we now also support RHEL 6.4 x64
* The driver package now includes a script for creating OpenStack Cinder Volume types. Read about Openstack Cinder volume types here.
Lets look at an example of the Volume types script we mentioned:
Assuming you have the following two backends configured in your cinder.conf file:
You can now run the 'create_volume_types.sh' script, to automatically create volume types to point to these backends.
After running this script, you can see your automatically created Volume types by running:
This is it!, your volume types are set and you can now use them when creating volumes:
#cinder create --volume-type IBM-XIV_hostdev31f.xiv.ibm.com_vwc_iscsi --display-name vol_hostdev31f 5

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.
