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.
The 'Software Defined Storage' (SDS) as says in its wiki (http://en.wikipedia.org/wiki/Software-defined_storage) is:
"an evolving concept for computer data storage software".
As such any storage vendor and client can see in it different things.
In this blog we give one such an observation of the SDS and how IBM Spectrum Storage™ family offerings, especially the new Spectrum Accelerate fits in.
Some Retro-perspective View:
In the beginning each server/computer had its own [direct... [More]
The countdown is on!
Meet IBM Storage at CeBIT 2015 in Hannover from March 16 to 20!
With IBM System Storage solutions , cost and complexity of managing large amounts of data can be reduced, while productivity of the staff and the infrastructure can simultaneously be increased to keep up with exponential data growth.
At CeBIT 2015, five demo booths for storage hardware and storage software will be showcased to demonstrate IBM’s storage topics, solutions and products:
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]
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]
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]
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.

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:
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]
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. In... [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]
There are two major categories of problems usually reported to the technical support:
Ongoing problems, including problems that happen again and again and problems that can be recreated.
One-time occurrences where a so called root cause analysis (RCA) is necessary.
Technically problems from these both categories could be very similar, but the fact if the support person needs to investigate something in the past or something that will certainly happen again in the future totally changes the necessary approach.... [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]

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]
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]
I was recently involved in some customer engagements and briefings related to secure data access and NFSv4. There seems to be some general misconception that NFSv4 deployments provide much more secure data access than NFSv3 deployments. Here are a few facts which I feel worth to clarify and share:
1. The weakness of machine based authentication
The traditional Unix security model is also referred as machine based or server based authentication. The root user authorizes a user to login on a server by creating a user account which... [More]
