I know its been a long time since I posted the first to parts in my "optimal performance" series, and I've been promising parts 3 and 4 for some time, but they are more or less written - well the basic information has been distilled into a presentation...
The world... [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]
“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... [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 -

It is hard to look anywhere these days without seeing Flash being used. I think the word that marketing like to use, unless it has fallen out of favour is "pervasive". Mind you in the hands of some people it is definitely moving from "pervasive" to "invasive" but... [Continue Reading]
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... [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]
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]
I was recently interview by Antony Ashead at ComputerWeekly to fill in some details behind IBM's recent FlashSystem announcements. To see Antony's write up, check out his article :

We are delighted to announce an exciting addition to the distribution channel of IBM Redbooks – now available at the Apple iBookstore is the ability to download, for free, (I probably should add some disclaimer about network charges may apply so this is it!) selected books. Not all books... [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... [Continue Reading]
A quick update from IBM Edge2013 at the Mandalay Bay, Las Vegas, and we are very pleased to have launched, announced, published as a draft paper the results of work that we have been doing with a company called Bridgeworks, and their SANSlide product. They are here at Edge and we were able to fine... [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]
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...
