  • Cloning in progress…

    Hi all, if you have been re-directed here from the old developerworks blog site, you will need to search here again for the topic you wanted as they could only setup a re-direct to the home page for any of our old content. Update as of 8th January 2020 I’m still cloning the old content across and thus far have made good progress … but have about 50 more posts of still relevant topics to submit, keep checking back and hopefully we should be up to date by the end of the month!

  • Configuring IBM Storwize V7000 and SVC for Optimal Performance – Part1

    DISCLAIMER – Please note that the RAID discussion, in terms of number of arrays matching cores is no longer relevant if you are using Distributed RAID (DRAID) – where a single DRAID array can use all the available cores. BW Dec 2019 For more updated DRAID information see ‘Configuring RAID/DRAID Best Practice’ ORIGINALLY POSTED 20th April 2012 TOP 5 POST 103,444 views on developerworks I’ve been involved in a quite a few pre-sales, proof of concept and after-sales accounts where people have setup their V7000 and then wondered about the performance they are achieving, is it optimal, can they do… [Read More]

  • Chilling with Infosmack

    ORIGINALLY POSTED 18th February 2012 9,587 views on developerworks A couple of weeks back I got together with Nigel and Rick over at Infosmack, spending some time discussing what got me into computing, how I ended up in storage and what its like to work in IBM.I have to admit that I did go and get my old BBC Model B out the attic and have a night or too messing around with old classics like Elite. You can listen or download the podcast from :http://infosmackpodcasts.com/chillin-with-barry-whyte-from-ibm/ [Read More]

  • Breaking the 500,000 IOPs SPC Barrier

    ORIGINALLY POSTED 3rd February 2012 20,233 views on developerworks Well, i guess I should first wish, any readers I still have left a Happy New Year.Not only are we now into 2012, but hey its February too, where did January go… must be some kind of temporal locality thing going on (private joke – sorry, all will become clear all too soon) For those of you that haven’t seen, we’ve just been credited as the fastest storage product ever, (again), with a new world record Storage Performance Council SPC-1 published result. The first product to breech the 500,000 SPC-1 iops… [Read More]

  • Announcing IBM Storwize V7000 Unified & v6.3.0 Software

    ORIGINALLY POSTED 11th October 2011 Top 20 Post : 28,837 views on developerworkls Its just about year to the day since IBM announced the IBM Storwize V7000, today we’ve announed the next major step in the evolution of the product, and the SVC code base at its heart. The IBM Storwize V7000 Unified. This integrates IBM’s Common NAS software which is used in the enterprise level SONAS product with the block based Storwize V7000. While the Storwize V7000 is block based at its heart, the addition of the new File Modules as interfaces to the V7000 means users can consolidate… [Read More]

  • The Gotchas of NAND

    ORIGINALLY POSTED 1st October 2011 14,765 views on developerworks 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 lot to say and was worthy of a blog in itself. SSD, and in particular NAND flash has various foibles as we all know, it has wear out characteristics, it has distinctly different read and write characteristics, and… [Read More]

  • Out of hiding. Farley becomes Poulton…

    ORIGINALLY POSTED 17th September 2011 12,995 views on developerworks  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 season that covered “the year of hell” – well it feels like we all woke up from something similar a few months ago… after the effort that was put in to get… [Read More]

  • [GUEST POST] – Storage Buddhist – To Infiniband and Beyond…

    ORIGINALLY POSTED 28th June 2011 22,983 views on developerworks Greetings this week from the Storage Buddhist as I do a guest spot on this blog for Barry. I’m wondering if he’s a little sensitive about Nigel Poulton‘s recent Infosmack jibe about how often this blog gets updated, so I’m stepping in while Bazza contemplates possible topics for his next blog entry. Personally I’d be interested in Barry’s thoughts on data compression… Anyway, the thing that caught my interest this month is InfiniBand. After a ten year gestation it seems to be cropping up more and more. Infiniband began to take shape back in… [Read More]

  • IBM at 100

    ORIGINALLY POSTED June 11th 2011 10,824 views on developerworks When Nigel asked the question about IBM’s age in Infosmack 101 I was initially amazed hat everyone didn’t instantly know that IBM is 100 this years young this year, next week infact. I guess internally we’ve had a lot more press about this than there has been externally. Anyway, on 16th June 2011 IBM as we ‘kind of’ know it, will be 100 years old. I say ‘kind of’ because there is a lot of pre-history before 1911, when Charles R. Flint merged the International Time Recording Company, the Computing Scale… [Read More]
