  • Storage Virtualization – Part 2

    ORIGINALLY POSTED 19th August 2007 11,419 Views on developerworks Cornerstone #1 – Online data migration It’s always nice to influence peoples lives in a positive way. Thoseof you reading this have no doubt had the fun of being ‘on call’ foryour respective company. That frantic storage call at 3am on a Sundaymorning when things haven’t quite gone to plan. Wouldn’t it be great ifthe tasks that storage administrators usually spend the wee small hours of aSunday morning doing could be done during the normal working day. Chuck Hollisi s one of the first to acknowledge that today’s storage has a… [Read More]

  • Innovation, Invention and Intellectual Property

    ORIGINALLY POSTED August 12th 2007 6,472 Views on developerworks I’ve seen a few comments in blogsphere relating to my ‘Master Inventor’ status and figured it was worth clarifying that this is an internal IBM accolade relating to services rendered in the area of innovation, invention and Intellectual Property (IP). Although in the last few years the US patent office has stopped officially releasing their top 10 lists, IBM has long been #1 with the most patents filed annually – in most years more than double that of the company in the #2 spot. Within IBM’s research and development labs disclosure… [Read More]

  • So just what do I mean by Storage Virtualization

    ORIGINALLY POSTED August 10th 2007 13,146 views on developerworks Less than one week into my blogging career, why not open a huge can of worms and let the ‘fishermen’ fight over the big fat juicy ones… I changed the title of this post several times before settling on the phrase “what do I mean” – this way I’m not dictating anything to anyone other than what I picture when talking about Storage virtualization and what this blog is intended to explore. Some months ago while meandering through Wikipedia I found a rather stubby Storage virtualization topic with a two line… [Read More]

  • SVC Questions and Answers 2007

    ORIGINALLY POSTED 9th August 2007 12,805 views on developerworks John and the OSSG have been discussing various aspects of SVC and Virtual SANs and I thought it was worth answering some of these questions in depth as well as clarifying some of OSSG’s answers. “It’s essentially a Linux server cluster” While this statement is kind of true, it also has some nasty implications without further clarification. In actual fact SVC does use a cut down version of Linux, the Linux kernel is simply used to bootstrap the box and then map all hardware into user-space, thus giving the SVC code… [Read More]

  • SATA Performance

    ORIGINALLY POSTED 4th August 2007 15,247 views on developerworks 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 low level data integrity of the drives, I believe that SATA may well suffer more than SCSI or FC with ‘missed-write’ issues (where the drive claims to have written the data but does not) however my gripe with SATA is the performance. While SATA… [Read More]

  • A place to call my own

    ORIGINALLY PUBLISHED 4th August 2007 10,328 views on developerworks Welcome. One of the good things to come out of the recent banter started by Chuck that dragged in Tony and Barry Burke, regarding the ‘relevance of SPC’ and storage benchmarking in general was a comment from BarryB regarding me having my own blog… So here it is. To set the record straight, from the start, I do not intend this to be a marketing driven blog – like statistics, you can market a product in almost any way you want – using Blogs as a means to ‘ignore the truth’… [Read More]
