Barry Whyte is a 'Master Inventor' working in the Systems Group. Now based in Auckland New Zealand, Barry is working for the IBM ATS team covering Storage Virtualization for the AP region. Previously Barry was based in IBM Hursley, UK. Barry primarly works on the IBM SAN Volume Controller and Storwize family of virtual disk systems. Barry graduated from The University of Glasgow in 1996 with a B.Sc (Hons) in Computing Science. In his 18 years at IBM he has also worked on the successful Serial Storage Architecture (SSA) and the IBM DS8000 range. Barry joined the SVC development team soon after its inception and has held many positions before taking on his long running role as performance architect. In 2015 Barry moved to New Zealand, but maintains a part-time working role for the Hursley team working as a performance consultant. Outside of work, Barry enjoys playing golf and all things to do with Rotary Engines.

While catching up on some old and new posts out here I came across an interesting article from Chris Mellor discussing a report about various PCIe card benchmarks performed by the Swiss National Computing Centre (CSCS).
I was going to reply to his post but as I started typing realised I had a... [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...

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]
These days I'm spending more and more of my time with customers visiting Hursley wanting to hear
about our smart planet initiatives, how we can help to make their infrastructure dynamic and of course
most of my involvement in this is around presenting how and where SVC and storage... [Continue Reading]
2000-2007 The "Virtual" Storage - SAN Virtualization Appliance Years First of all thanks again for all the feedback regarding this series of posts, great that people are enjoying a bit of a history lesson, or even a reminder into your own histories!
So where was I... The Hursley team... [Continue Reading]
So after all the EMC hype, and all the claims that the DS8000 was "pushing up daises" it seems
that IBM have managed to announce the GA of ship our sub-lun hot-spot management, aka Easy Tier before EMC
have shipped their FAST function. Now, before you all jump and say EMC have been... [Continue Reading]
As you may or may not have seen, IBM has agreed to acquire Texas Memory Systems : http://www-03.ibm.com/press/us/en/pressrelease/38594.wss This has many implications (all good) for SVC, Storwize V7000, and Pure Systems. Better integration with existing RamSan products, and of course integrated... [Continue Reading]
Last week I had a couple of meetings in Manchester (UK) with some SVC and V7000 end users, as well as the chance to pop in and say hi to our team in the IBM Manchester labs. About two days before heading up the M6 I was asked if I'd like to join in a roundtable session with UKFast - discussing the... [Continue Reading]
The Serial Storage Architecture Years - 1990-1998 Its been a crazier than ever year. All will become clear soon. But one of the things I wanted to discuss with you all is just what kind of history comes with the team of ~150 storage people that I work with on a daily basis. Of course there are a...

Hi all, Happy New Year (are we almost in February already!)
This is just a quick heads up, the next UK based SVC, Storwize family User Group meeting is planned for the 8th of May 2013. To register, see here :... [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]
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 am still alive. I know I've been crap at posting for the last year or so, and really when it comes to it, I'm not going to say I'm sorry... for those of you that like sci-fi, and are of a certain age... those of you that watched Star-Trek Voyager when it first aired, will remember the half...

While googling I spotted an interesting topic from Chris, discussing the application of SATA drives in the enterprise. Quite rightly for years most vendors have been telling their customers that SATA is no replacement for SCSI or Fibre-Channel enterprise class disks. I don't know enough about the...

Cornerstone #5 The potential to increase system performance While this topic directly corresponds with ‘Cornerstone #5’ it does also contribute #2 Simplification of storage management and #4 Increased storage utilization Pooling and Striping Most enterprise level controllers, the likes of DS8000,...
