I completely missed the announcement a couple of weeks ago for version 7.8.1 of the Spectrum Virtualize software. Traveling too much at the end of last month and forgot to post an update on whats new. This release I am dubbing the ‘customer council’ release. Last year we started a...   [Continue Reading]

Here’s another topic I often get asked about. Things used to be quite simple and I covered this for many years in my Configuring for Optimal Performance series of technical university presentations (also here on the blog - parts 1, 2, 3) - and the basics are still the same when configuring...   [Continue Reading]

Spectrum Virtualize Quorum Happy New Year to all. I’ve been getting a few questions relating to quorum devices, and in particular the IP quorum and what happens when various different failure scenarios occur. I thought it was worth detailing things here. So first some background. What are...   [Continue Reading]

 Today we are lucky to have the first in a series of guest posts from Dr Bill Scales. Bill is one of the lead product architects in the storage team in Hursley.

Yesterday I spent an hour or so looking for something I knew was out in the blogosphere so I could pull down the reference to it, its frustrating that even when you know something is out there, and no amount of google search phrases can find it for you. But what I did find was a couple of my old...   [Continue Reading]

Just to make life as difficult as possible for the development and test teams, and not content with refreshing the lower end Storwize V5000 products earlier this year, today IBM is announcing a refresh to the Storwize V7000, FlashSystem V9000 and SVC platforms, some new all-flash variants of...   [Continue Reading]

A few weeks back myself and Lloyd Vickery, from the IBM NZ Systems team, attended an IDG run CIO roundtable event. The insights from those attending give a great view into the concerns and needs of CIO's today - when it comes to data, getting useful information from the data, and the ethics...   [Continue Reading]

New “Differential” Licensing Over the years its become clear that a TB isn’t what it used to be, for example the maximum tier of SVC license capacity back in 2003 was 32TB… so things have changed. We wanted to reflect this in the managed (mdisk) capacity licensing. Not all...   [Continue Reading]

Last week I covered some of the main updates in the 7.7.0 release of Spectrum Virtualize, this week I am in IBM RTP in North Carolina and can fill you in on yet more!

Hi all, I know over the years I've had hundreds of enquiries regarding the XML statistics, what they contains and how they can be decoded. Some of you have written your own parsers and need to know when new things have been added or items changed. Google isn't much help as it finds, the old...   [Continue Reading]

Its that time again, another six months since our last software update and we bring you version 7.6 of the Spectrum Virtualize software. Applicable to all SVC and Storwize systems currently supported out there, but not the end of life for support of 8G4 and 8A4 systems in the RFA details issued last...   [Continue Reading]

I think its true to say that the SVC and Storwize User Groups that IBM has helped to setup and run has created a real community of users and partners around the globe. There are very active groups in the UK, Germany, France, Belgium, Sweden and Finland and of course the USA. (Sorry if I missed some)...   [Continue Reading]

Over two weeks ago, we released v7.5.0 of the recently re-branded 'Spectrum Virtualize' software, that software that we all know as the code running in both SVC and Storwize products. The major new feature in 7.5.0 is HyperSwap - which you can think of as a new and improved Stretched Cluster...   [Continue Reading]

Hi all,   A quick update to let you know of a new blog here on developerworks that should be worth adding to you RSS feeds/reader.

I do have a good excuse this time for the short hiatus in posts, as things have been a bit more crazy than normal, but to be expected when you up and move the whole family, literally to the opposite side of the globe!

In this very concise IBM Redpaper we describe the procedure for making use of an IBM SAN Volume Controller (SVC) Standby Storage Engine in a SAN which is not a part of any cluster, but is a candidate and able to join a cluster at a moment’s notice. The purpose of this is to reduce the impact...   [Continue Reading]

With half term week here in the UK and preparations for next months travels, I almost forgot that yesterday we announced the contents of version 7.4.0 of the SVC and Storwize software that will be GA'd on 28th November. The full RFA can be viewed here , but here's a quick summary....   [Continue Reading]

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...   [Continue Reading]

I guess a few folks will comment that I'm raising my head again at announcement time, and true, but thats part of the problem on working on new and exciting stuff, I can't talk about it until days like today where we have announced two major new engines in the SVC and Storwize family. I even...   [Continue Reading]

I think that this Heartbleed bug is going to be an observational comedian's dream. Well I guess one that is a bit of an IT geek anyway. Not quite sure what the Pub Landlord will make of it, but I am sure that he will have some kind of an opinion. Probably not fit to print. Anyway, on to the...   [Continue Reading]

Starting with IBM Storwize Family Software V7.2, including IBM SAN Volume Controller, we introduced native replication over IP networks. As this IBM Redpaper describes, you will see that it is easy to configure in an existing IP infrastructure. This is a lower-cost alternative to the Fibre...   [Continue Reading]

I think I missed January, it certainly seems like February has snuck up on us - maybe its because every day here in the UK is merging into one... since us Brits love to talk about the weather... its been kinda boring, rain rain, oh look its raining.

As most people are aware (see Barry's post) we just announced the Storwize V5000. It fits neatly between the Storwize V3700 and the V7000. And of course no product is complete without an accompanying IBM Redbook.   So, here goes:   One new one:  ...   [Continue Reading]

Some of you may have spotted we release another Storwize Family member back in July, but in limited geographies. Today IBM announced world-wide availability of the IBM Storwize V5000. As the name suggests, this product sits firmly between the Storwize V3000 and Storwize V7000 ranges, in terms of...   [Continue Reading]

I know, I promised this some months ago, and I've been enjoying my spare time too much, and not blogging enough! So rather than keep you all waiting even more, here is a PDF of the presentation I gave at IBM Edge 2013 in Vegas. Hopefully most of it is self-explanitory, and I WILL post some more...   [Continue Reading]

For the last few years we have often talked about 'flexible hardware' options for SVC. While we have offered the internal SAS HBA and SSD attachment within the nodes, and a 10Gbit iSCSI/FCoE capable upgrade, we've never quite made it to true flexible hardware, with respect to Fibre...   [Continue Reading]
