We''re preparing to purchase an X4170M2 as an upgrade for our existing X4100M2 server for ZFS, NFS, and iSCSI. We have a choice for CPU, some more expensive than others. Our current system has a dual-core 1.8Ghz Opteron 2210 CPU with 8GB. Seems like either a 6-core Intel E5649 2.53Ghz CPU or 4-core Intel E5620 2.4Ghz CPU would be more than enough. Based on what we''re using the system for, it should be more I/O bound than CPU bound. We are doing compression in ZFS but that shouldn''t be too CPU intensive. Seems we should be caring more about more cores than high Ghz. Recommendations? -- albert chin (china at thewrittenword.com)

I know the Exadata storage cells use them but they aren''t utilizing ZFS in the Linux version of the X2-2. Has that changed with the Solaris x86 versions of the appliance? Also, does OCZ or someone make an equivalent to the F20 now? -Gary
