Re: IMPL of P0 partition

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

Why is this a lie?  There is no disk controller, no disks, no LAN card, 
slots used. No i5/OS maintenance or security. Nothing to load when you 
get the machine like a P0 partition, the FSP code is already there. The 
FSP sits in a reserved slot leaving all other resources for your use. In 
addition many FSP fixes can now be loaded concurrently without taking 
down any partitions at all. This is a great improvement over LPAR on 
pre-i5 machines. Granted it's not perfect and you do have to restart all 
partitions during an FSP Version upgrade, but it's certainly better and 
is improving. It's clearly not a lie.
