I am not convinced that old gear offers much in the way of value. ![]() and fits inside the typical host, reducing power and complexity. It offers Spaceballs-class "Ludicrous Speed" compared to a shelf of two dozen SAS HDD's. SAS drive prices tend to be out of line: a DAS RAID controller with a quartet of 1TB SSD's is less than $3000. We used to buy drive shelves like the MSA7o in order to build up IOPS capacity for spinny drives an individual drive might only have 100 IOPS but 24 of them would be 2400 IOPS aggregate! But now it is all screwy. The build quality of the HP gear is very good but with their recent firmware upgrade policy change we won't be buying their servers. Geekbench 3 results are around 11000 for these. With four 3.5" 7200 RPM HDD's (FreeNAS! Yay!) and running the CPU full out I can get these up to 110, 120 watts MAYBE. We've also got some X9SCi-LN4F with E3-1230 running as ESXi hosts. Geekbench 3 results are around 6000 for such a machine. Even with the HE CPU's these things average 250 watts. We've got some HP D元65G1's (~2008-2009 era) running as ESXi hosts, dual Opteron 2346 HE (8 cores at 1.8GHz).
