Testbed and Methods
The following benchmarks were used:
- IOMeter 2003.02.15
- WinBench 99 2.0
- FC-Test 1.0
- Intel SC5200 system case
- Intel SE7520BD2 mainboard
- Two Intel Xeon 2.8GHz CPUs (800MHz FSB)
- 2 x 512MB PC3200 ECC Registered DDR SDRAM
- IBM DTLA 307015 hard disk drive as the system disk (15GB)
- Onboard ATI Rage XL graphics controller
- Windows 2000 Professional with Service Pack 4
The controller’s firmware was version FE9X 3.08.02.005 and the driver version was 3.00.02.140. 3DM version 2 was used for monitoring and synchronizing the arrays.
The controller was installed into a PCI Express x8 slot but the 3DM program reported that it worked in PCI Express x4 compatibility mode then. Well, the 10GBps bandwidth available in that mode was quite enough for our arrays that consisted of a maximum of 4 disks.
We didn’t test RAID6 because the 3Ware 9650SE-16ML didn’t allow us to build a RAID6 array out of four disks.
The Western Digital WD740GD (Raptor 2) hard disks were installed into the standard boxes of the SC5200 system case.
The controller was set at the Performance mode for maximum performance during the tests. This mode allows deferred writing and look-ahead reading for both the controller (in its own buffer memory) and the disks. The Performance mode should not be used without a cache battery because there is a high risk of losing data in case of a power failure.
