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.
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]
Will you be attending the 2014 IBM Systems Technical University (STU) in Istanbul next week?
If you’re not registered yet, you better hurry up now!
The STU is the perfect venue to ramp up quickly on smarter computing implementation, gain an in-depth look at the latest innovations from IBM Systems, learn about recent product announcements, exchange insights with colleagues and learn from the ESCC experts!
To be honest, we are certainly quite proud that a significant portion of the... [More]
Flash storage, cloud and data analytics are three technologies which impose significant change to storage. All three cover three different aspects. I have noticed that a clear definition of these topics is beneficial for discussions about storage. Here are my definitions:
1. Cloud Storage
Cloud (storage) is imposing disruptive change to IT by offering a very cost effective delivery model which forces vendors, providers and customers to optimize hardware, software and operations for the new cloud delivery model. This... [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…)
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]
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 .
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]
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]
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 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]
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]
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]
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]
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.
