Thanks, Everyone for your input and its very useful.

Hi Donald, Some of the reasons for the consolidation is for Data Center effectiveness such as Power, Space and Cooling + going green. Analysis is still going on to find different solutions available with pros/cons. ESX 3.5 with multiple VM Hosts for the Windows (SQL, AS) and Linux (Oracle) servers using SAN is one of the options; Blade is also being considered with no Vmware solutions for the Production Servers; Development could sit on VM solution for the Windows but how to handle Oracle on VMWare is another question.

Thanks, Again for the inputs.

We recently moved several databases from HP rp5450 (L2000) servers running four PA8600 processors (single-core) to Oracle Linux on Dell 2950s running dual quad-core Xeon X5450_at_3GHz processors, so the Oracle licensing was the same since we went from 4 single cores to 8 multi-cores after the .5 licensing multiplier for Intel procs.

The new system is MUCH faster - my database refreshes via exp/imp used to run in about 2-3 hours and now run in 15-30 minutes. This is even with running on top of VMWare ESX 3.5.

We did also upgrade from 8i to 10g and switched to a new SAN at the same time, so it's not exactly apples to apples, however the 8i to 10g change shouldn't make that much difference on exp/imp (no, I'm not using datapump), and the SANs we moved from/to were pretty similar in performance so I don't think that accounts for much of the difference either.

Regards,
Brandon

Also, Looking to move the hardware from HP PA RISC architecture to x86 using Linux. What is the equivalent of 4 Dual Core PA8900 processeors compared to the HP Machines especially DL-G Series.
