Two years of trouble with S5000PSL

Problems:

Occasional Crashes: BSOD, hangs, or restarts: most of the time after crash/restart one or more Drive Cages is missing. Need to pull the power-cables. Wait a few minutes. Connect cables, boot and drives are back.

Most of the time No crash information in Windows.

Restart in OS: often one or more Drive Cages are missing (after restart NOT A CRASH). Need to pull the power-cables. Wait a few minutes. Connect cables, boot and drives are back.

RMM2: no remote console posible (Vista/MacOS/XP, can login to RMM2)

RMM2: first page of SEL log not visible

Intel Management: software interferes with windows OS: unable to install and use Intel Management

OS:

Windows Small Business Server 2008 SP1 (64 bit)

Windows Small Business Server 2003 R2 SP2 (32 bit) (replaced by SBS 2008)

Hardware (Intel):

Chassis: SC5400LX

Motherboard: S5000PSL

RMM: RMM2

Drive cages: AXX4DRV3GEXP and AXX6DRV3GEXP

Firmware/Drivers:

all components have latest versions

Intel Support:

Dozens of emails: problem still exists

So far I tried:

- Replaced all Harddisks (found several problems with Seagate Barracuda 7200.11 SATA II Disk Drives)

- Replaced Drive Cages's EXP4 and EXP6

- Replaced RAID controller (Intel SRCSAS18E -> Adaptec 5805) (both crash in the same way)

- Replaced OS (new clean installations): before SBS 2003 -> now SBS 2008 (both crash in the same way)

- Replaced RAM

Please help,
