No dedicated storage cost. We use a single SAN for everything, its cost is shared. Cost of P6? Around 400K. For a box that runs at last count 12 partitions inside it, each is a db server or app server. With plenty of room to spare. It sits in a standard rack using up 6 pizza slots so infra-strucutre costs are quite low.

Yeah, and it's running one system/db/app. I'd like to see it running 12, with spare capacity...

Last week in our Wintel cloud box. We also run a very large HP Intel VMWare-based "private cloud". All the Wintel stuff runs on it. That's all the MSSQL servers plus all app and web servers. Quite a few. That box cost us a LOT more than the P6...

No way. Any similarity between an original RS6K Power box and the current P7s
for example is pure coincidence. They have also evolved, as dramatically as PCs
or even more.
The big decider has always been how much one can stash inside one of these
boxes. 10 years ago they were dedicated to a single server. Nowadays,
everything is either lpars or vio partitions. With room to spare.
Sorry, don't know what SUN is doing in that front: it's been more than a decade
since I last touched one of them. They never overly impressed me...
