A group blog about IBM storage, storage news, hints and technical discussions by EMEA storage experts. The postings on this site are our own and don't necessarily represent IBM's positions, strategies or opinions.
We are excited to introduce you to this new group blog of IBM storage experts from EMEA (Europe, Middle-East and Africa).
Storageneers is for "storage engineers" and that's already pointing to our main topics: Technical information, hints, news, opinions, and discussions about storage.
Being the first post in a group blog, we will update this one from time to time to introduce the new bloggers. (Updated on Dec. 3rd 2013)

As Sebastian mentioned in the first post of this new blog you will
find some cool information about IBM Storage Products and their
surroundings. I am Hannes, working for IBM as second level support
for IBM XIV Storage systems for nearly five years. For a long time I
thought a blog would be a cool/nice add-on to my daily work in order
to deliver some insights into our business and products.... Now I
made it ;) Here is my first post:
On the 11th of March 2013 IBM released Version 2.0 of
its Host Attachment Kit (HAK) for IBM... [More]
In general Storage Area Networks (SAN) and Multipathing Software can cope with permanent errors quite well.
For example if one specific path stops working due to a permanent cable or SFP error, the system will switch over to the alternative redundant path.
In turn the defective path will be taken offline. Now if the system detects later that the offline path is available again, the path will be set online again.
XIV HAK news
On June 26th IBM announced a Version 2.1 of the IBM XIV Host Attachment Kit! It's available again via FixCentral and we recommend to update to the latest version.
The main feature is the support for 11.3 Code on XIV Storage Arrays and the IBM Hyper-Scale Mobility (formerly known as OLVM) feature; we will publish another blog post soon on this topic. In addition it gives a couple of small fixes and a new rule-set for the previously mentioned xiv_host_profiler feature.
So if you like the xiv_host_profiler... [More]
I recently read a wikibon article I must have missed two and a half months ago when it was published. Scott Lowe wrote IBM’s FlashSystem Isn’t For Mainstream CIOs…yet . In summary he appreciates IBM's efforts to drive flash technology forward but he clearly sees all-flash arrays being in the early adopters phase and only interesting for special clients with special workloads (other than "mainstream CIOs" ). The world doesn't seem to be ready for flash.
But it really is.
IBM Hyper-Scale Mobility
IBM Hyper-Scale Mobility is a no-cost feature introduced in XIV Storage System software version 11.3. This level of software is available since May 2013. Prior releasing this software the naming was changed from OLVM (Online Volume Migration) to IBM Hyper-Scale Mobility, which is now the official name.
The feature allows users to move volumes from one XIV System Gen3 to another XIV System Gen3 with no interruption before, during, and after the migration.
Field of application for this feature is... [More]
There it is again: one of those supposed-to-be-rhetorical headlines Betteridge's law is all about. Well of course, your storage environment could be robust enough. But let's have an honest look on it.
Working in the storage support I often come across little misconfigurations or other for itself minor conditions (like stuck VCs ) causing problems. Keeping in mind that - in most of the cases - a storage environment is designed with dual fabric redundancy it should not really be a problem to do... [More]
Tape storage has been around since more than 60 years now. Since 1952, to be exact, when IBM invented the concept of magnetic tape storage. There have been many great inventions and improvements in that time frame, and although the statement "Tape is dead!" was exclaimed quite regularly over the last two decades, tape storage is still here! And I believe it's here to stay, at least for as far into the future as I dare to look.
Let me explain, why:
Nobody in the storage industry would deny that tape still has a... [More]
It's like big family which gathers for an annual reunion, and by saying big, I mean really big. More than 250 customers, business partners and IBMers gathered for the fifth "SVC & Storwize User Day" in Mainz, Germany with attendees from all over Germany, Switzerland and Austria.
Speakers from those countries but also from Israel, USA and UK gave insights on history and future of the SVC & Storwize product family. Several customers from small to big business presented their experiences of implementing their storage... [More]
In 2011 a DS8000 client changed from IBM to a different service provider in order to service his DS8000 machines.
As they were out of warranty this was a legal way to go.
Just recently the client has signed again new maintenance-contract with IBM.
Shortly after signing the contract several DS8000 boxes reported defective battery-sets.
These battery sets are needed in case of an AC power-loss to preserve client data.
What happened ?
Whilst the maintenance was done by the service provider, client... [More]
Last week IBM released a security bulletin named " Unauthorized access exposure on IBM SAN Volume Controller and Storwize Family ". It's about vulnerabilities in Apache Struts that could allow a person with access to the IP interface of a Storwize family product to gain 'superuser' rights on said machine. Being a superuser you can configure the machine and yes, with the sufficient amount of criminal energy you could even delete the whole configuration. Given the... [More]
We have great news: There is an excellent replacement alternative for IBM Information Archive (IA) and DR550 as well as for new archiving solutions: the SSAM solution . System Storage Archive Manager (SSAM) is a variation of Tivoli Storage Manager (TSM) which is made for compliant archiving and is key component in IA and DR550. SSAM solutions can be well positioned as DR550 / IA replacement and for new archive solutions based on three invincible arguments:
SSAM is certified for compliance according to international laws and... [More]
Cloud storage is an often discussed topic in various industries. There are various solutions being evaluated for cloud storage, but only a few seem to consider the usage of tape technology. By ignoring tape, you miss a great range of potential advantages.
Let me describe some use cases with LTFS EE (Linear Tape File System, Enterprise Edition) technology, based on a technical paper summarizing “ Applications of LTFS for Cloud Storage Use Cases ”, which was published by the Storage Networking and Industry Association (SNIA)... [More]
Several times in a row, Mainz once again had been selected to become the core ITSO Redbooks site for the updates of the main DS8000 Redbooks publications. In Q4/2012, we had hosted the Redbooks for the first generation of DS8870. In Q2/2013, updates on the Easy Tier Redpapers were done. along with the Copy Services books. Now October and November 2013, the updates dealt with the second generation of DS8870 (sixth generation of DS8000), which has been announced 19 November 2013 .
The English translation of the assessment report for System Storage Archive Manager 6.3 (SSAM) is available now. This is an important milestone, because SSAM has been certified for compliance according to international laws and regulations .
System Storage Archive Manager (SSAM) is a variation of Tivoli Storage Manager (TSM) which is made for compliant archiving. SSAM provides... [More]
