Can you use SVC with XIV as storage ?
YES , you can !
XIV and SVC can be a great combination, we have many customers using this combo.
Why ? flexibility and support for operating systems the XIV does not support.
But don't you have to pay twice for licenses if you want to do mirror data ? NO, its a special XIV license for the SVC which includes all the features that comes with the XIV, but for the SVC instead, neat isn't it ?

DFSMS is the standard methodology worldwide for managing enterprise data and storage on the z/OS platform. It provides an automated, centralized, policy-based solution for z/OS storage management. While there are many new enhancements in z/OS V2.1 DFSMS – the following are 5 of my favorite.
RLS support for catalog
This DFSMS release introduces RLS usage for ICF... [More]
We recently published the IBM® Redguide™ Taming the Data Beast with Tarmin GridBank and the IBM XIV Storage System to coincide with the IBM XIV® Storage System announcement on October 8. One of the key concepts (aha moment) for me while working on this Redguide was the opportunity to scale the data and the management of the data using the grid-based products together.
My colleague Jon Tate recently posted information on the IBM Request For Enhancement Community.

While bimbling around in developerWorks the other day I stumbled across something that I had long forgotten about. Well I am not entirely sure that I had ever seen it but I like to convince myself I know what is going on !
Anyway, sometimes we get spoiled in IBM having access to development at the click of a button so there is usually no need for us to utilize any other means to start a dialogue with them. Of course there are user groups, focus groups, informal and formal networks, social... [More]

Recently we published an IBM Redbooks Solution Guide on Implementing IBM Easy Tier with IBM Real-time Compression.
IBM® Easy Tier® is a performance function that automatically and non-disruptively migrates frequently accessed data from magnetic media to solid-state drives (SSDs). In that way, the most frequently accessed data is stored on the fastest storage tier, and the overall performance is improved.
How does it work
Every volume is split into logical units... [More]

Many of you may have heard of "diskcore" (and tapecore too) and always wondered what it was and how you might be able to use it, or whether it was some uber-secret society that if you had to ask to join, then you weren't going to get in, or you needed a funny handshake to be invited. Not so.
When Tim Berners-Lee (before he was knighted) and an untold number of "geeks" were still playing around with HTTP, possibly using a Netscape browser that ran on OS/2 (I have no... [More]
Complex, aging, and inflexible IT infrastructures create business challenges and raise administration costs. Low utilization, low efficiency, and storage and performance bottlenecks create additional limitations. IBM FlashSystem storage products can be used with IBM PureFlex Systems to create seamless hardware integration across server, storage, and networking. PureFlex Systems also provide centralized management on the compute, storage, and network layers.
Here are 5... [More]
“To err is human; to forgive, divine.” Alexander Pope.
Well we are mixing up poetry and Star Wars here today (or tomorrow, if it is already tomorrow where you are), and finish it off with a cryptic message.
Anyway, let's cut to the chase here: a long time ago, in an IBM Redbook far, far away (December 2011), in an effort to get out timely information to the field, the first draft (which was a pre-review version), of the IBM Redbook Implementing the IBM Storwize V7000... [More]
The Faster Microsoft SQL Server Performance with IBM FlashSystem Storage, TIPS 1038 IBM Redbooks Solution Guide describes techniques for improving SQL database performance by integrating FlashSystem storage into your environment.

This IBM Redbooks publication documents these Best Practices available for SONAS based on experience gained from actual... [More]
As 2013 draws to a close and travel gets harder as 4Q rapidly approaches, I have decided to try something a little different (yes, yes, I know we have done it in the past but normally only after some on-site attendance has taken place) and I am going to consider/pilot remote participation for some applicants for my residencies until year end.
So, if you have seen this residency: IBM Storwize V7000 Unified Redbook Update, ST-3D36-R01 you may have noticed this... [More]

The TS3500 Shuttle Complex can access over 300,000 tapes and is now supported by IBMs Tape System Library Manager ( TSLM ) and High Performance Storage System ( HPSS ). Here is a figure from the book of the TS3500 Shuttle Complex. Select the link above to the... [More]
Just over a week or so ago we completed the ITSO Redbook residency to create a book based on the SAN Volume Controller and the IBM FlashSystem 820. Now, normally we like to get these things out very quickly and the team, Danny Bryant, Christian Burns, Joao Marcos Leite, and Denis Senin worked very long hours to make this happen. As is always the case they were helped by those awfully nice developers at IBM Hursley in the UK, the home of storage virtualization.
What they could not have... [More]

Early adopters of virtual desktop infrastructures (VDIs) that relied on hard disk drives (HDDs) were disappointed by the lack of performance of the solution:
Response times suffered because of the unique nature of the I/O demand that VDI places upon the storage subsystem.
Scaling the infrastructure meant adding expensive, yet inefficient, tier-one storage to handle the additional I/Os, even if capacity were not an issue.
Management of the infrastructure sprawl became... [More]
