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.
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]
In classical IT, every data set expires at some point in time. “But not anymore!” I hear those Big Data analysts shout! “We want to store as much data for as long as possible, just in case we find an attractive use case for it in future!” Or, stealing a line from my favorite comic strip, “Calvin and Hobbes”: In Big Data, there’s treasure everywhere! (By the way: You might want to visit http://www.ibm.com/analytics/us/en/index.html to find out how IBM helps you to uncover that treasure…)
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)

Moving to software defined cloud environment, there is no way to get around OpenStack. OpenStack is an open source infrastructure as a service (IaaS) solution that basically is able to control and manage entire IT infrastructures.
It is a component based solution that includes the following major components:
Storage: BlockStorage: Cinder
Storage: Object Storage: Swift
From the very beginning OpenStack is designed to be massively scalable from small to ultra large... [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]
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]
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]
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]
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.

Elastic storage lives from its use cases. One use case has been around for years: Running TSM servers on GPFS storage.
We would like to elaborate on this use case and demonstrate some outstanding performance test results.
For those who don’t know those product, IBM® Tivoli® Storage Manager products provide backup, archive, recovery, space management, database and application protection, and bare machine recovery and disaster recovery capabilities. They can help protect a wide... [More]
The new LTFS Enterprise Edition (LTFS EE) release 188.8.131.52 is now available. There are many new functions in this release . I want to show you the most exciting ones, some of them I tested in our Lab.
Tape Libraries TS4500 and TS3310 are supported: In addition to the TS3500 two new IBM tape libraries are supported. The TS3310 allows creating small LTFS EE solutions, perhaps leveraging the LTFS EE entry configuration bundle . With the TS4500 enterprise solutions with LTFS EE can be established.
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 .
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]
True flash architecture – that means being designed for the purpose of ultra-high performance from scratch, and not being limited by a Device Adapter, or FC-AL shortcomings. If you look at the specs of typical SSDs of today, each single drive could do tens of thousands of IOps, but when it comes to creating a RAID across a small pack of these, then we see the real results. Traditional architectures often also call themselves “flash”, but in fact were just using SSDs and kept putting them behind the same Device Adapters that... [More]
