We are happy to announce that we have released several drivers to support the new version of the OpenStack Cinder project: Ocata. This, however, is not an ordinary release, and here's why: previously, the drivers for IBM SAN Volume Controller, IBM Storwize Family, and IBM FlashSystem V9000 storage systems were the only ones included in the OpenStack community source code. Now, this latest release is a huge step forward aimed to include IBM FlashSystem A9000 and A9000R, IBM XIV, IBM Spectrum Accelerate (deployable software), and IBM DS8000 Family systems in the community source code as well, moving from proprietary code to being fully open-source. So henceforth, the IBM Storage Driver for OpenStack is part of the OpenStack Cinder repository. Accordingly, the driver documentation has also migrated from IBM Knowledge Center to the OpenStack community website: https://docs.openstack.org/ocata/config-reference/block-storage/drivers/ibm-storage-volume-driver.html
This release was developed in accordance with the OpenStack Ocata specifications, emphasizing our continuous commitment for providing IBM storage customers with cutting-edge OpenStack capabilities. In addition to the aforementioned integration in the community source code, this driver version includes enhancements in replication functionality (also known as "cheesecake") of the supported IBM systems, as well as improvements in multipath support, and auto-selection of I/O groups for Storwize storage systems.
As always, we are here to help with deployment and operation of our OpenStack drivers. Your feedback is important to us, and we'll be happy if you let us know what you think about this milestone release.
The IBM Flash Centers of Competency has posted a very good blog about our latest SCB version

To all our blog followers,
It may have slipped your radar (mostly because we haven't advertised it yet...), so we're happy to let you know about the YouTube channel of the Cloud Storage Solutions developer teams in Tel Aviv and Shanghai:
The content of this YouTube channel is produced and brought directly by the group developers themselves, so just be aware that the videos are provided on "as-is" basis.
At this point, the channel contains videos about IBM Spectrum Accelerate Family Provider for Microsoft Windows Volume Shadow Copy Service (applies to IBM XIV, IBM Spectrum Accelerate, and IBM FlashSystem A9000 and A9000R), and about IBM Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service (applies to the Spectrum Virtualize family storage systems).
We strive for improvement and enhancement, so please feel to post your comments on any particular video, and if you would like to see videos on solutions that are not yet on the channel, please let us know.

It's been a while, but now we're back with our brand new IBM XIV Host Attachment Kit 2.0.0!
You probably noticed that we made the jump to version 2.0.0, and for a very good reason: We have an exciting new feature we've been developing for the last 6 months - xiv_host_profiler.
xiv_host_profiler introduces a new approach in the way we provide support to hosts connected to XIV systems. The utility gathers information about your host's configuration, analyzes it against a set of best-practice rules, and enables pre-emptive identification of storage connectivity problems. And this is exactly why we recommend running it on a regular basis.
This feature is also tightly integrated into our latest XIV System release 11.2. By default, when using xiv_host_profiler, the collected information gets uploaded to your XIV System for further analysis. This ability will assist our technicians to ensure your hosts' health before commencing XIV System upgrades or other procedures.
For privacy reasons, the information collected by xiv_host_profiler is only related to your host's storage connectivity status - items such as the host's HBA model, installed OS version and the configuration state of the multi-path framework.
After collecting the information, xiv_host_profiler is also able to analyze it against a bundled set of rules:
The rules against which we analyze the host's configuration will be updated regularly and can be downloaded from Fix Central
As mentioned before, it's best to run xiv_host_profiler at least once a week (in order to keep the data as up-to-date as possible). We provide an easy way to do so - simply run 'xiv_host_profiler --create-scheduled-task'.
As usual, you can read more about xiv_host_profiler (and other HAK utilities) in the Host Attachment Guide and Release Notes, as well as in the man pages included in the HAK package (how? simply run 'man xiv_host_profiler').
We believe HAK 2.0.0 and the included xiv_host_profiler will further improve on the way we support our storage systems and the hosts connected to them. We'd love to hear more from you about your needs and expectations in the comments.
In the meantime, you can download yourself a copy of the Host Attachment Kit for your favorite host's operating system, right here

Hi Everyone !
It's HAK release time again !!
As part of our ongoing efforts to keep the IBM XIV Host Attachment Kit up to date and provide enhanced and new functionality, we are proud to announce the latest Host Attachment Kit version 1.9.0.
In this new version we have added support for several new platform versions:
Solaris 11, the recently released Red Hat Enterprise Linux 6.3 and the latest AIX 5.3, AIX 6.1 and AIX 7.1 Service Packs which introduce IBM XIV LUN 0 support.
But we did more than that. We have also enhanced the current HAK functionality by providing our UNIX & Linux users with manual pages accessible by using the 'man' command. Now you can access the documentation for each HAK command by executing 'man <HAK command>'.
In addition, in AIX OS, 'xiv_attach' is now capable of automatic discovery of connected XIV systems and host definition on the connected XIV, by utilizing the latest AIX 5.3, AIX 6.1 and AIX 7.1 SP, in which XIV LUN0 support was added. This aligns the XIV support in AIX OS with that of other supported OS-s. Moreover, LUN0 support also introduces a new HAK utility to AIX HAK users - 'xiv_syslist' , which you can read more about here
The log collection utility, 'xiv_diag', was enhanced and now can be executed in unattended mode by providing the command with the destination path for the compressed log collection package as a command line argument.
Finally, additional bugs and known issues were resolved, and you can read more about them in the Release Notes.

Get your hosts ready, as the new HAK is in now available! The latest 2.9.0 release improves connection stability when attaching hosts to storage systems in IBM HyperSwap and Hyper-Scale Mobility deployments.
As in the last few releases, HAK is available for Windows, Linux, or AIX hosts. A quick reminder for HAK newbies: it allows your hosts to easily connect to volumes on IBM Spectrum Accelerate Family storage systems (FlashSystem A9000 and A9000R, XIV, Spectrum Accelerate deployable SW) over iSCSI or Fibre Channel.
Version 2.9.0 also supports the 1Q18 milestone software release of FlashSystem A9000 and A9000R, version 12.2.1, as well as the RedHat Linux 6.9 and 7.4 releases.
You can download HAK 2.9.0 from IBM Fix Central. Check out the HAK version 2.9.0 documentation on IBM Knowledge Center, which includes the HAK lifecycle and compatibility matrix, latest release notes, and user guide, which now - by the way - has additional info and references regarding host multipathing with FlashSystem A9000 and A9000R. Also, if Microsoft Windows Server is the OS of your hosts, check the new list of required hotfixes (KBs) page (previously listed in the release notes) for error-free operation of your hosts.
As always, your feedback is always welcome.

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’.
