We are currently running 3 TSM servers at Version 5.5, two on z/OS and
the third on a Solaris 10 box.  We have been tasked to combine these
into one.

The current Solaris system is on a Sun V240 w/8GB memory:

   Around 400 clients (combined) including a 3TB Exchange system, and a
      fairly large SAP implemtation in development on MS SQL Server,
      several Oracle boxes, and a large number of Windows servers.

   Total database size (Solaris) is around 80GB, expiration runs about
      two hours.  z/OS databases total 50GB.

   8 TS1120 tape drives in a 3494 ATL.

   1.2TB array for storage pools and database on the Solaris server
      which we are currently trying to separate.

   Total daily backup volume is around 1TB with additional weekly
      backups of 9TB.

I am the TSM guy and the z/OS systems programmer and as such don't
really have a feel for hardware sizing or configuration on the Unix side
of things and so have to rely on our Unix guys.  I suggested that AIX
would be the preferred platform for this implementation with another
Solaris box having the advantage of not requiring converting the exist-
ing one.  They came up with the following options with their favorite
being the x86(HP) with Linux because it is much cheaper and they claim
would be more powerful. The AIX and Sun configurations are similar in
price at around 5 times the x86.

Thought, comments, considerations? What are people using for disk
storage pools and would the internal drives on these boxes be adequate?
I'm also in the process of freeing one array on our ESS800 (Shark) for
fiber connection to this configuration.

Here are the proposed options:

IBM Power 550 Express                HP DL380 G5
Up to 8 cores and 256GB RAM          Up to 8 cores and 64GB RAM
Six 300GB internal SAS 15k drives    Eight 146GB internal SAS 15k drives
Three PCIe and two PCI-X slots       Four PCIe slots
Dual port 10 GB Ethernet card
4 GB fiber channel cards - x2
