The following excerpts from recent press release shows the current state of art in memory

• On the top-end 16-way p5 570, IBM installed AIX 5L V5.3 and DB2 8.1, crammed 512GB of main memory into the box (as much as IBM and rivals were able to support last year on 32-way and 64-way servers) …

• This server had an unbelievable 614.3TB of disk capacity, which is an absurd amount.

• But it would be interesting to see, for instance, what a p5 570 with 16 cores activated would do in terms of TPC-C performance with fewer than 1,640 15K RPM Fiber Channel disk drives whirring around under their frames. Say, with something closer to 5TB or even 10TB of disk capacity, which would still be a lot of capacity for a database server.

• Perhaps disk capacity is as far ahead of server needs as memory capacity is behind it.
