Re: 64 BIT ADSM API in ADSM 3.1.2.30 /40

64bit processors (called RS64) today are only available in IBMs "high-end"
models labeled e.g. H70, S70 or (soon) S80. All other processors inside RS/6000
systems are "only" 32bit. Therefore it seems that you have to put your ADSM
server on a S70 or the like to exploit the 64bit features. But I assume that a
perfectly sized, configured and tuned I/O subsystem (including adapters, disks,
tapes etc.) on a 32bit machine will give you more power compared to an
"out-of-the-box" 64bit system

Subject: 64 BIT ADSM API in ADSM 3.1.2.30 /40
Hi all,
could somebody elaborate on the 64 bit API used in ADSM 3.1.2.30 /
40.
The 604E processor on our RS6000/ F40( As well as most models) is , I
believe a 32 bit processor.
And as per figures obtained from the internet many of the processors of
RS6000 seem to be 32 bit.
Would I be correct in presuming that there may not be performance benefit on
most RS6000 models until we upgrade it to a 620 processor.?
Sincere regards
sri
