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 ?
Very often I get questions on how to configure the XIV when... [More]
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 catalogs in a parallel sysplex environment. The... [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.
This Redguide publication explains how the... [More]
My colleague Jon Tate recently posted information on the IBM Request For Enhancement Community.
For all you Tivoli Storage Productivity Center enthusiasts, you can search the submitted Tivoli Storage Productivity Center RFEs or submit a new RFE through the Service Management Connect Team Blog.
The Tivoli Storage Productivity Center on the Service Management Connect Team Blog has the links to the Wiki, Forum, Blog and Support Portal. It also contains useful information like Tivoli Storage Productivity Center release... [More]

And, if you are serious about trying to extract as much as possble out of IBM Storwize V7000 and SVC, then this is a must read for you:
Configuring IBM Storwize V7000 and SVC for Optimal Performance ... parts 3 and 4
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 media, and so on, that can connect you a lot... [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 called extents . Easy Tier is based on algorithms that... [More]
All, I just announced this residency: Best Practices for SVC/Storwize V7000 including RtC, ST-3D30-R01 .
It will be hosted by IBM Israel in their Tel Aviv offices.
The book that we are updating is: IBM System Storage SAN Volume Controller Best Practices and Performance Guidelines .
I know it is 4Q and if you have problems getting time away from the office, then I might be able to accommodate remote participation.
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 idea if Netscape ever ran on OS/2 but I know that... [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 things you should know about integrating IBM... [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 V6.3 , SG24-7938-01, contained the following...

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.
If latency, or I/O wait time, is limiting the speed of your database, consider upgrading your storage. Faster processors and increased bandwidth might be wasted if applications still wait on storage. Storage efficiency is often measured in input/output operations per... [More]
Now that you have implemented IBM Scale Out Network Attached Storage (IBM SONAS), you may be at the point where you are interested in Best Practices for daily administration and monitoring of the SONAS. There is a new draft available of the IBM SONAS Best Practices , SG24-8051.
This IBM Redbooks publication documents these Best Practices available for SONAS based on experience gained from actual implementations and daily administration .
