Hi Derek

I have the 3ware 9xxx-series SATA II RAID card -- it's actually a 9550SX-4LP.

I am using four drives (500GB Seagate SATA II 3GBit) with 3 of the disks as RAID 5 with the 4th as a Hot-spare. Instead of 2TB disk space I end up with about 1TB and a live fail-over drive (supposed to be completely hardware controlled in the 3ware RAID card bios...)

I have three servers, more or less identical, each has 8GB ram with 2 280s; here is a general breakdown of the specs:

Debian 4; 2.6.18-5-amd64 (SMP)

Processors 4
Model Dual Core AMD Opteron(tm) Processor 280
CPU Speed 2.39 GHz
Cache Size 1024 KB
System Bogomips 19137.72
PCI Devices 00:07.1 IDE interface: Advanced Micro Devices [AMD] AMD-8111 IDE
00:07.2 SMBus: Advanced Micro Devices [AMD] AMD-8111 SMBus 2.0
00:0a.1 PIC: Advanced Micro Devices [AMD] AMD-8131 PCI-X IOAPIC
00:0b.1 PIC: Advanced Micro Devices [AMD] AMD-8131 PCI-X IOAPIC
01:03.0 RAID bus controller: 3ware Inc 9550SX SATA-RAID
02:09.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet
02:09.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet
03:05.0 Mass storage controller: Silicon Image, Inc. SiI 3114 [SATALink/SATARaid] Serial ATA Controller
03:06.0 VGA compatible controller: ATI Technologies Inc Rage XL
03:08.0 Ethernet controller: Intel Corporation 82557/8/9 [Ethernet Pro 100]
IDE Devices hda: Slimtype DVDRW SSW-8015S
SCSI Devices AMCC 9550SX-4LP DISK (Direct-Access)
USB Devices Linux 2.6.18-5-amd64 ohci_hcd OHCI Host Controller
Linux 2.6.18-5-amd64 ohci_hcd OHCI Host Controller

The actual drive performance has been very similar among the systems and except for a weird BIOS issue I have been very happy overall.
