We are seeing a lot of these - anyone else?

You have a failing DIMM - totally normal...call dell and get it replaced.

Yes we have opened cases with Dell

We've had 5 of these in two weeks

Seems like too many...

You may have caught a bad lot. I have seen this kind of issue where issues will "cluster" around a set of systems deployed from a lot that was purchased at the same time. Dell should be able to square you away.

While we dont use R900s for virtulization, we do use them for other stuff, and have also seen much higher than average failure rates.

We have logged 24 memory events on 4 R900’s since in the last 3 months - we escalated to a Dell technical acct mgr and were told today this issue has to do with the memory brand itself which is “Hynix”.

Stay tuned!

Just had an MPmerory error in one of our brand new PE R900 server.

MPmemory error: Southbridge CRC Error (XMATS32 FAIL).

We are also using 4 GB Hynix memory modules (HYMP151F72CP4N3 - Y5)

Escaleted to Dell technical account manager

Maybe these are the problems only apply to certain batch of R900. I have 3 of my R900 running for a year now and never experienced the issues reported here.

According to Dell the plan is to replace any of the memory in the servers that falls within a certain manufacturing date window and on some of the servers it involves a complete memory swap.

dmidecode will give you the spec on the memory:

Handle 0x1101

DMI type 17, 28 bytes.

FYI,

the dell rep is recommending we replace 237 four Gigabyte (Hynix) Dimms from the dmidecode analysis -

I think we'll be getting that platinum uplift for free now - this is a big problem - even with vmotion zero downtime it will take days.

you need a 10gb connection for your Vmotion, that will really help :smileygrin:
