Multiple E200i Cache Module failures in BL460c G1 servers
In the past 12 days, we've had 3 servers go down, due to what appears to be bad controller cache modules. Last night alone, we had 2 go down. Since it was after hours and the servers and the TS farm they're a part of were not in use, I was able to do a lot of troubleshooting. I swapped parts between the working and non-working servers and pin-pointed it to the controller cache modules. The batteries are fine, the controller/backplanes are fine, etc etc. Everything works in the other servers, except the cache modules. The error follows the cache modules... The error is that the controller failed the self-test. It also appears there is no way to boot these servers with out a working cache module.
The blade servers have been in use for about 2 years now. Are we just hitting the life expectancy for the cache modules? Was there maybe a bad batch of cache modules? Any one know what might be going on? 1 failed after just a system reboot and the 2 last night went down after I installed more RAM.
I already contacted support and we have 2 more modules on their way, but I'd like to know for the future what may be causing the failures. Maybe we need to purchase a couple extra modules to keep on hand? We have 40 blades right now, so I'd just like to get tot he bottom of this before I have to go through 40 tech support calls and getting fired for having 40 servers fail in the next month. ;)
The servers are all BL460c G1's with e200i controllers.

Also, since it will probably help... the cache modules are part number 413486-001. The 128MB modules with the attached battery pack.
