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!
My wife was born in New Zealand and spent much of her youth there, with most... [Continue Reading]
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... [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. It feels more like being back in Scotland where we... [Continue Reading]
I see that EMC have finally pushed yet another technology family on its customers. Extreme I/O arrays. So now you have to decide which one of these things do I want.
OK, let me buy an all flash array, so how will that fit with my VMax and VNX estate - oh it wont -

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:

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... [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... [Continue Reading]
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... [Continue Reading]
