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 would like to share the first preliminary results (see figure 1) of our Proof of Concept (PoC) running Tivoli Storage Manager (TSM) workloads on Elastic Storage with GPFS Native RAID (GNR) over 40 Gbit Ethernet connections. Thanks to Sven Oehme from IBM Research who provided us with the infrastructure and expertise configuring the GNR and TSM server systems.
The peak throughput results are amazing as you can see below:
The ‘IBM Spectrum Scale / Elastic Storage / GPFS Expert Workshop 2015’ was a 2-day workshop delivered by experts for experts. This year we had again a mix of speakers ranging from customers and business partner to IBM technical services, development and research.
Before the official start Frank Krämer warmed up at 8.30am with ‘IBM Spectrum Scale for Beginners’. I was not able to join, because I had a customer briefing in parallel, but I was told that this session was very well attended. I like Frank’s... [More]
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]
Recent news about the new IBM System z13 were the initiator to look back over the last years and summarize IBM synergies between IBM Storage and System z mainframe computers.
IBM System Storage synergy with System z has long tradition at IBM, resulting in many benefits like improved application efficiency, performance and highest possible system availability, due to resiliency functions like remote copy, which are managed by System z software and services packages for effective DR setups.
Already in the 1980s IBM... [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]
I would like to share some experiences configuring Information Lifecycle Management (ILM) with Elastic Storage GPFS 4.1, in particular regarding automatic migration with more than two storage pools and tape being one of them. The ILM function in GPFS allows to seamlessly and transparently migrate data from one file system storage pool to another. A file system storage pool is a collection of storage devices with the same characteristic.
GPFS ILM Function and Policies
For example a file system might have two... [More]

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]
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)
Hannes Bellmer is an IBM Product Field Engineer... [More]
When we look at IBM’s strategy for Software Defined Storage (SDS), then the clear focus lies on Elastic Storage .
Elastic Storage is a proven, scalable, high-performance data and file management solution, based upon IBM General Parallel File System (GPFS) technology. It provides simplified data management and integrated information lifecycle tools capable of managing petabytes of data and billions of files.
Today I want to focus on the fact that Elastic Storage supports Flash, Disk and Tape under a single name space. This is a... [More]
Just recently, Gartner published a report, titled “Magic Quadrant for Deduplication Backup Target Appliances”. This is a completely new analysis, so I’d call it a “Gartner’s first look” on this market.
Strangely enough, the large majority of products were ranked as “niche players”. While this might be an obvious choice for many of the products, I was quite astonished to see IBM’s ProtecTIER solution also ranked as “niche player”.
In the report, Gartner mainly describes... [More]
I have recently supported an implementation of System Storage Archive Manager (SSAM) with storage pools on N series Snaplock volumes. I would like to share some experiences especially when event based retention is used with SSAM.
The drawing below shows the system architecture. The SSAM software runs on AIX in this example. The AIX server is connected via 10 GBit Ethernet to the N series which is configured to provide NFS shares based on snaplock volumes. The SSAM DB is stored on internal mirrored disk of the AIX server. The storage pools... [More]
The product line of the IBM System Storage DS8300 and DS8100 machines has been among the most successful in the history of IBM storage, and along with their smaller sister DS6800, we still have many customers enjoying these products in the field, typically using extended warranty contracts by now.
As per the announcement http://www.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_ca/7/897/ENUS915-087/index.html (for Europe, cf. http://www.ibm.com/common/ssi/printableversion.wss?docURL=/common/ssi/rep_sm/6/877/ENUS2107-_h06/index.html ),... [More]
Security as an Inhibitor to Cloud Adoption
"50% of executives stated that security concerns were the key inhibitors of cloud services usage" says a recent report by IDC.
Taking on this central concern brought Dominik Brugger, Erik Rüger, Marcus Breuer, Thorsten Mühge, Itzack Goldberg and Matthias Seul together - working cross-team, cross-division and even cross-geography. As Cloud is one of IBM's central business plays it was obvious that creating trust in the safety of data wherever it may be was the key... [More]
Just recently, Storage magazine/SearchStorage.com published the results of their ninth annual Tape Libraries Quality Awards. The results were derived out of 473 evaluations from 321 users, covering five main quality categories. So I believe there’s sufficient market insight and user experience behind the results.
In the “Enterprise Tape Libraries” category, IBM’s TS3500/TS4500 was compared against Hewlett-Packard’s ESL/EML Series and Oracle’s StorageTek SL3000/SL8500, among other competitors.
The emerging field of "brain inspired computing" has the potential to revolutionize the computer industry. So why is it so promising to design new computers inspired by the human brain?
Current computer processors are based on the “Von Neumann”-architecture that originates from 1945. This design is extremely powerful for analytic tasks like calculations, regression analysis etc. State of the art computers can execute tasks with ultra-high speed of up to 5 Ghz or an equivalent of 0.2 nano-seconds per operation.
