Secure your data with industry-standard data-at-rest encryption with no performance impact .
With the ever-growing landscape of national, state, and local regulations, industry requirements, and increased security threats, ensuring the protection of an organization’s information is a key part of operating a successful business.
Encrypting “data at rest” is a key element when addressing these concerns.
Here are a few key facts about XIV encryption:

Cloud computing is defined as the use of computing services and resources (hardware and software) that are delivered over a network, typically Ethernet. OpenStack is being developed as an industry standard Cloud computing project. OpenStack is a global collaboration of developers and cloud computing technologists producing the ubiquitous open source cloud computing platform for public and private clouds. To learn more about OpenStack, refer to the project website at: www.openstack.org

Today, the changes in our world include the instrumentation, interconnectedness, and intelligence of our environments. Such changes combine to produce a massive glut of new useful information, from new and existing sources, with new ways to use it. These pressures typify a few of the storage challenges that we dealt with for some time now, but on a whole new scale. Businesses face a tidal wave of information and data that seems to increase daily. The ability to successfully and efficiently manage information and data has become imperative.... [More]

This Big Data Networked Storage Solution for Hadoop Redpaper provides a reference architecture, based on Apache Hadoop, to help businesses gain control over their data, meet tight service level agreements (SLAs) around their data applications, and turn data-driven insight into effective action.
I was in Las Vegas during Edge2013 and had a chance to talk to the IBM Product Manager of Storage for Big Data Analytics and HPC. I had printed a hardcopy of this Redpaper to give to him and just as... [More]
A draft of the Flash or SSD? Why and When to Use IBM FlashSystem IBM Redpaper publication was published on June 4 th , 2013.
Read this guide to learn about why and when to use FlashSystem storage and how it compares to other storage technologies such as hybrid arrays, PCIe Express products, and hard disk drives (HDDs). It also helps explain the differences between FlashSystem products, solid-state drives (SSDs), and other types of flash storage implementations.
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]
All communication between the XIV GUI, XCLI, Multi-System Manager and XIV systems utilize Secure Sockets Layering (SSL) via x509 certificates.
Beginning with XIV Storage System Software version 11.2 and XIV Storage Management Software version 4.1, you have the flexibility to install and use your own x509 certificates in addition to the built-in certificate. You can choose to use a certificate that is signed by either a trusted Certificate Authority (CA) vendor or your organization’s own private CA server. There are four steps required to... [More]

Since I have been involved in developing Redbooks and Redpapers for IBM® Storage, Storage Cloud, Storage Systems and Solutions the past few years I have noticed a theme that continues to grow with each project: IBM General Parallel File System (GPFS™). GPFS is more than storage it is about data management. The initial GPFS support in the OpenStack® Cinder Havana Release is evidence of the growing value of GPFS in the Cloud Infrastructure.
If you are thinking it is time to learn more about GPFS here is... [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.
Announced on October 6 ( 2014), the DS8870 Release 7.4 (Licensed Machine Code 7.7.40.xx.xxx) brings enhanced replication options, improved synergy with System z, additional flash optimization, and new capacity options as well as an improved DS GUI .
The planned availability date is December 5 , 2014.
New replication options :

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.

The port to local node communication is used for mirroring write cache as well as metadata exchange between nodes and is critical to the stable operation of the cluster. The DH8 nodes with their 8-port and 12-port configurations provide an opportunity to isolate the port to local node traffic from other cluster traffic on dedicated ports thereby providing a level of protection against misbehaving devices and workloads that could compromise the performance of the
Additionally, there is benefit in isolating remote... [More]
Prior to the version 7.2 SAN Volume Controller software release, stretched cluster configurations did not provide manual failover capability, and data being sent across a long distance link had the potential to be sent twice. The addition of 'site awareness' in version 7.2 routes I/O traffic between SVC nodes and storage controllers to optimize the data flow, and it polices I/O traffic during a failure condition to allow for a manual cluster invocation to ensure consistency.
The use of Enhanced Stretched Cluster continues to... [More]

I was flying above the clouds headed for Tokyo after working on our Redbooks Publication IBM SmartCloud Storage Access V1.2 Implementation Guide in Shanghai. It was a very uneventful flight and then I saw something looming in the distance rising up through the clouds. Although I tried to tie the object up ahead to an analogy of my storage cloud work I quickly figured out that we were doing an amazing fly by of Mt. Fuji from 20K+ ft.
Recently, I published a draft of a new Redpaper,... [More]
No, this is not a pre-announcement of the death of Lotus Notes. Nope, what this is is something that came out of a discussion we were having on a residency that I am running about some whizzy new hardware that will be announced very shortly. While I was waiting for what seemed like an eternity for Lotus Notes to wake up and open itself, one of the residents said "have you upped the JVM memory setting?". What, says I in my best I haven't got a clue what you are talking about expression.
So, a few clicks later and a restart of... [More]
