Re: iSeries and Sans

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

Mark,

This is where LPAR fits so well. You can create a partition on the i 
that is just used for hosting disk for x and AIX/Linux partitions. Since 
that partition isn't used for development or web serving or Java or C or 
such things, the requirement that it gets the latest greatest PTFs is 
minimal. Routinely we see these partitions running for a year without 
PTFs.  Your dev partitions can be updated and IPLed without so much as a 
hickup on the hosting partition side.

This is clearly the sort of setup I would recommend in your environment.

Hopefully in a soon to be released version IBM will allow i5/OS to be a 
guest of another i5/OS partition.  Now THAT has me drooling at how 
simple it would be to create a new partition!
