Hi Jeff,

After meeting with NOAA/FSL folks today, I find that I need to update
some comments I sent to you this morning.

re:
>The only comment I would like to make is that the UPC is moving towards
>64-bit systems, and Xeons are 32-bit.

This is incorrect.  The Dell PowerEdge 2850 Xeons are apparently 64 bit
processors.  This was news to me.

re:
>The configuration of the V20Zs we have is:
>
>dual 2 Ghz Opteron
>4 GB RAM
>dual 72 GB 10K RPM SCSI (I am not positive on the disk space here)
>cost of $3000 under an educational discount program that has now ended
>unit is in a 2U box

Our machines have dual 36 GB 10K RPM SCSI disks, not dual 72 GB ones.
Also, the V20Zs are 1U not 2U.

Sun has a newer version of this box out that has faster Opteron
processors, dual 72 GB SCSI disks, but not as much RAM (2 GB vs 4 GB)
for -- I believe -- $3500.  Your PowerEdge 2850 specs has a lot of
disk, and that will significantly bump the cost of a machine.  We don't
need much disk on our IDD relay machines, so we were not concerned with
purchasing added capacity.

The rest of my comments stand:

- we have found the V20Zs to be excellent performers for LDM relay
  activities
- we really like Fedora Core 3 64-bit, and were informed that RedHat
  Enterprise WS 4 is essentially FC3 turned into a supported distribution
  by RH
- the V20Zs do not perform well as user workstations since its video
  support is poor
