Shared Storage Pools - five videos to Get You Started Today

If you read this blog regularly then you will know I am a fan of the VIOS Shared Storage Pool technology.
It is a major peice of the "Making PowerVM and VIOS - easier to live with and reduce the man-power" story and it is hard to believe that we started withPOWER4 virtualisation in 2000 and VIOS in 2005. This does mean that the tools we use (HMC and VIOS padmin) need a bit of an update and I know these are in plans for the future. Even now we can start using SSP to save lots of system admin time and be more flexibly and for sure SSP is a large part of the future.
I have just released four new videos that cover SSP and a month ago one covers the new SSP phase 3 features. Some are about SSP directly but others are about how SSP can really improve fexibility (LPM is so easy with SSP, moving LPARs from a crashed machine in a minute and Assimilating older disk technology LPARs to give them LPM and a performance boost). Also don't forget SSP offers snapshots - this is really cool for trying upgrades and instany rollback (if you have a problem or want to script it and get it right) - OK it does take 1 minute to reboot the LPAR but the SSP roll-back is sub-second.
Here are links to the four new videos and the SSP3 new feaures one - all on YouTube :
I am looking forward to beta testing the next SSP release as there are lots of new features and I would like to tell you about them ... but I am not allowed. I will blog about them as soon as I can. Cheers, Nigel
ps: If you have large stable production workloads with high disk I/O rate requirements then stick with what you have and are familiar with - if it ain't broke etc. For workloads that need remote disaster recover disk environments wait for the next SSP release or use SSP with a SVC. But for all the other virtual machines / LPARs I would today recommend SSP. Put it this way - I am moving all my LARs to SSP. This assumes your VIOS is current 2.2.2.x, has FC adapters and you have a few TB spare on the SAN disks.
