UCS C220M3 + 9266 massive failures, help

[joel.sersol]

Hi all,

We recently purchased 70 Cisco UCS C220 servers with the LSI 9266 8-port card.  These are specced as follows:

* 2x E5-2680 processors

* 8x SFF 1TB HD's

* Basic networking (2 ethernet, 1 CIMC)

* 128GB of RAM

* LSI 9266 - RAID5 across 7 disks, 1 hotspare

* Firmware: 1.5(3d)

* Operating System: RHEL 6.4

* megaraid_sas version:  2.6.32-358.el6.x86_64

We have recently run into alot of issues with these systems where under full load the system will stop responding because the OS thinks the RAID card has gone away and the CIMC even reports this.

What I would like to know is if anyone else has had issues with these? if so what revision is the RAID card.

Thanks,

-Joel

Ok we will space them, we have rack space for these since they are a bit power hungry.

Glass door on a rack huh?  must be for showing off ot execs?  I wouldnt have done that personally or professionaly since it would surely impede airflow..  I guess everyone has different needs for these.

Thanks again Kenny:

That was my post :-)   There was no deliberate choice of glass for the door, it was just that the cabinet was that way from new - and it hadn't been a problem before.  Having the C220 installed in an engineering/test rack like that which is easily accessable and allows us easy access to the hardware has been very useful in the short term for testing/training etc.
