    Hardware choice: 4 single core 32bit Xeon CPU or 2 single core 64bit Xeon CPU?

      Hi there!

       

      I'm quite a newby with virtualization, I did some tests on a HP Proliant DL380 G3 server with serveral products and I'm really satisfied about ESXi.

       

      Now I would like to build a server with 4 virtual machine: 3 of them will use 3 different Linux distributions and 1 will use Microsoft Windows Server 2003 R2 32bit edition. One of these machine will be used as a VoIP PBX.

       

      I've got 3 servers available:

      - HP Proliant DL560 G1, with 4 x 32bit 3Ghz Xeon CPUs with HyperThreading, FSB 533Mhz, 4MB L3 cache, 8GB DDR RAM, 2x146GB HD, Raid 64MB

      - IBM xSeries 346 8840, with 2 x 64bit 3Ghz Xeon CPUs with HyperThreading, FSB 800Mhz, 2MB L2 cache, 8GB DDR II RAM, 3x73GB HD, Raid 256MB

      - IBM xSeries 346 8840, with 2 x 64bit 3.2Ghz Xeon CPUs with HyperThreading, FSB 800Mhz, 2MB L2 cache, 8GB DDR II RAM, 2x146GB HD, Raid 256MB

       

      I'm wondering if I will have the best results with a dual single core but 64bit CPU server or with a quad single core 32bit CPU server.

       

      I browsed this community and I found several experiences posted by users, but I didn't understand wich could be the best solution

       

      Thanks to everybody that will help me!!
