Virtualization and the ISP (part 2)

Saturday, October 4th, 2008

Ah, the dreaded part 2 of the series.

I ordered my test system from Dell on Tuesday, September 30th, 2008, and the box shipped on Thursday, October 2nd, 2008. I am excitedly waiting for it.

The box I ordered is to test out the I/O performance for the mail server virtualization, the config is:

  • Quad Core Xeon E5420, 2.5Ghz, 2×6MB L2 Cache, 1333Mhz FSB
  • 16GB (8×2GB FBDIMM)
  • Quantity 4 146GB, 15K RPM SAS disks
  • PERC6/i RAID controller
  • Dual Port Intel 1000PT

So, not a huge machine, though not small either. If this works out well, then I’ll order up 8 of them to start the compression of my physical servers into virtual servers.

  • POP/IMAP servers
  • Apache based web servers
  • SMTP (inbound, delivery, outbound) servers
