The longer the day goes it seems to get slower. Students on the outside of the network on the internet complain more than the students behind the firewall on the inside network do.
Base Unit:
PE R515 with up to 8 Hot Swap Hard Drives, LED and AMD Opteron 42XX Procs (225-2372)
Processor:
AMD Opteron 4162EE, 6C 1.7GHz, 2M L2/6M L3, 1333Mhz Max Mem (317-5456)
AMD Opteron 4162EE, 6C 1.7GHz, 2M L2/6M L3, 1333Mhz Max Mem (317-5465)
Memory:
32GB Memory(8x4GB),1333MHz Dual Rank LV UDIMM for 2 Procs,Sparing (317-5503)
Our setup is like this: we have 2 R515's with 32 gig of RAM each
1 Tera of HD in a RAID 5 configuration.
The Servers are configured with ESXi 4.01 and one server with our web on it and the other is the db. Both servers are running Cent OS 5.7, with Zend php and MySQL. We have a Vcenter server running another box.
Running th preformanc.php file gave me these numbers
