Hi all, I currently have a OCZ Vertex 4 SSD as a ZIL device and am well aware of their exaggerated claims of sustained performance. I was thinking about getting a DRAM based ZIL accelerator such as Christopher George''s DDRDive, one of the STEC products, etc. Of course the key question i''m trying to answer is: is the price premium worth it? --- What is the (average/min/max)

Hey folks, We've got some new hardware and are trying to figure out what best to do with it. Either run CentOS right on the bare metal, or virtualize, or several combination options. Mainly looking at : - CentOS on bare metal - CentOS on ESXi 4.0 with local disk - CentOS on ESXi with 1 VM running Openfiler to serve disk to other VMs And want to benchmark these 3 scenarios So far all we

Hello. I am looking to see if performance data exists for on-disk dedup. I am currently in the process of setting up some tests based on input from Roch, but before I get started, thought I''d ask here. Thanks for the help, Janice

Hi there Is it fair to compare the 2 solutions using Solaris 10 U2 and a commercial database (SAP SD scenario). The cache on the HW raid helps, and the CPU load is less... but the solution costs more and you _might_ not need the performance of the HW RAID. Has anybody with access to these units done a benchmark comparing the performance (and with the pricelist in hand) came to a conclusion.

on Solaris 10 5.10 Generic_118822-23 sun4v sparc SUNW,Sun-Fire-T200 I run #iostat -xn 5 to monitor the IO statistics on SF T2000 server. The system also have a heavy IO load, for some reason iostat donot refresh (no any update). It seems like iostat is calling pause() and stucked there. Also my HBA driver''s interrupt stack trace indicates there is a lot of swtch(), the overall IOPS
