Smart Array 641 unreliable on ML370G4 - what to replace it with?
I have an ML370G4 which has been having problems recently with random freezes (current MTBF 2 days), and I notice that when it is frozen, one of the status LEDs (the rightmost of 8, marked MSB) on its Smart Array 641 controller is turned amber, so I'm assuming I need to replace that board. First, am I right? Second, that particular controller seems to be discontinued for a long time, so does anybody have any suggestions as to what I should replace it with?
Thanks for any help.

Re: Smart Array 641 unreliable on ML370G4 - what to replace it with?
HI Tony,
This could be a number of issues, here are a couple of things to try before spending any cash.
1: move the 641 to another alot.
2: Reseat the SCSI cables.
3: If it's got the 128MB cach upgrade module & you arent running any RAID 5 arrays try removing this module and leaving it to run off the onboard 64mb read cache.
4: Run the smart array diagnostics for your o/s and see if the board has captured any historical errors that might point to a likely culprit.
If none of these work then replacement 641/642 controllers are available on eBay these days for pennies as ar the beefier 6402's. The other less desirable option is that the nmotherboard is faulty & these still command a fair price.
Hope this helps.
Cheers
Mark

Thanks a lot.
I'll take advantage of downtime to try those things one by one, and I've bought a used controller as well, which will be handy to have anyway.
Tony.
