One final comment came from a list member who speculated that the larger
disks would cook because the SBB modules were not designed to dissipate the
heat.
This reminded me to emphasize the risk in going the unsupported route.
Anyway, some quick research turned up that the 140/10krpm gig ibm drives and
the 180 gig/7.2krpm seagate drives use about 10 watts at idle and 15watts
operating. This number is in line with the equivalent 36gig drives.
Thanks to all again.

Well,
I got several responses.
Hpaq supports a 36gig drive in the RA8000.
Hpaq doesn't support anything larger in that cabinet.
Hpaq supports a 72gig drive in the MA8000.
Hpaq doesn't support anything larger in that cabinet.
There is a 72 gig drive available in an SBB, a DS-RZ1GC-VW, $1500.
This is not supported by Hpaq in the RA8000.
One brave soul, has removed the smaller drive from an SBB and
replaced them with 180gig Seagate drives and is running quite happily with
them for several months in an RA8000.
For me, It is necessary to go the unsupported route. I'll probably
get a couple of seagate 180/7200rpm or ibm 140gig/10krpm drives ($1000each),
test them out on various configurations and deploy them as necessary. I'll
be relying on the raid controllers and good backups to provide the support I
need.
Thanks to all who responded!

Subject: HSG80 disk drives.
I have several HSG80/RA8000 storage systems. I am running
Tru64/4.0G/5.1A/Openvms7.2-1/AIX4.3/NT4.0 connected to these devices via SAN
Fabric/Fibre Arbitrated loop. The 36gig drives I'm using are not keeping
up with the growth.
Are there plans to support 72/144gig drives?
I've cracked open the plastic SBB modules and replaced some
of our old 9 gig drives with 36gig ibm sca drives with great success
(unsupported). If I have to, I'll buy a couple of 72/144gig sca drives and
test them out.
