[Spacewalk-list] Recommended hardware

[Eric]

Hello,

I have been testing Spacewalk with success.
We are looking to have one Spacewalk Server with two Proxy servers.

We have roughly about 500+ Solaris/RedHat servers we want to monitor and 
maintain.

What are typical bottlenecks experienced with Spacewalk/Satellite server?
Most of the (>70%) of the servers are located on our local network.

I assume that it will be one of the following:
  1. Oracle Database (RAC 11gR2)
  2. Physical Memory
  3. CPU
  4  Disk I/O
  5  Network I/O

We are looking at using a server with a single Intel E5640 (Quad core w/ HT) 
2.66 GHz with 6GB of RAM and two 10k RPM SAS drives in a RAID 1 configuration 
for the Spacewalk and the 2-3 other proxy servers.

I plan to have 2-3 proxy servers horizontally tiered to a single Spacewalk 
server.

Thanks in advance,

-Eric
