My ramblings on the stuff that holds it all together
Link here – good visualisation about 10mins in of how their new Chicago data centre is laid out internally.
With virtualisation breaking the traditional hardware/OS ties; this is becoming an increasingly appealing way of managing commodity compute grid resources for large organisations. Mike makes some good points about the de-comissioning of servers on a large scale where you are adding 10’s of thousands on a regular basis – you need to take them out at some point too, and that’s time consuming. at this scale of operation It’s more efficient to make the the container and/or datacentre the field replaceable unit (as I discussed a while back) in this scenario.
Also interesting point that water consumption may be the next environmental touch paper for legislation and disclosure for IT shops.
VMWare are shaping up to have a really good set of management tools – lab and site recovery manager are of particular interest to me for several projects I’m working on.
There is a new site here (disclaimer: it does seem to be promoting a commercial service, but has some useful information that has been put into the public domain); describing some methods to roll your own P2V backup approach; I’ve not read in detail yet; but looks like Frane Borozan has solved some of the challenges I’ve encountered in the past automating the Free VMWare Convertor tool.
When I get some time I will revisit my build a better test lab series (and update it!) I hope to be able to integrate some of Frane’s ideas.
Thanks to Techhead for passing on the link; we worked together on the platform underlying the Build a better test lab series and he did a lot of work on the P2V and post-P2V automation tasks – he’s got a lot of handy scripts for doing this on an HP platform
Virtualized DR is going to be big this year; I have a long line of customers with this high on their list of priorities… Both for cross site 100% VMWare implementations and for the ability to backup/restore physical platforms to VMWare grid in a DR situation.
It just makes so much sense; no delay whilst racking & stacking recovery kit or problems restoring to different hardware etc. your admin’s can even do it from home – which can have some significant advantages in the event of a natural disaster like Katrina or floods like we had over the last couple of years in the UK
PlateSpin Forge is something we are seriously looking at as well as Symantec Backup Exec System Recovery Server Edition (who win a prize for extending the longest, most annoying product name! despite acquiring it from Veritas).
Will be an interesting year; I’m sure Sungard and all those recovery centre facilities will be moving to a grid/resource rental model rather than pure rack/floor space and retained hardware on-contract.
