UCSC 240M4X TRC for UC Apps

[madhav.kumar.bhardwaj12]

We are using UCS C240 M4X for our UC applications. It says that UCS C 240 M4X is TRC server for UC applications.

Above guide says that to use Four virtual drives (VD) with RAID-5 and Each VD has five 300-GB hard drives. But in our UCS 240M4X we only see 6 driver with each 900 GB space then how we can make each VD with five 300-GB HD ?

We are using Cisco 12G SAS Modular Raid Controller (SLOT-HBA) in our UCS 240 M4X.

PID says that it is UCSC-C240-M4S and i can see 20 core on it so i assume it is UCS C 240M4X

TRC doc says to use Four virtual drives (VD) with RAID-5 and each VD has five 300-GB hard drives.That makes total 4X5X300=6000 GB

With 6 drive on my UCS =6X900=5400 GB

If your server does not have 20 x 300 Gb drives then it would not be TRC deployment and perhaps it was purchased as Spec based. The current and previous TRC models with part numbers are listed here and I don't see any of the C-series servers with larger than 300 GB drives:

+5 for Chris !!

Thanks for response Chris. So if i use Virtual Disk group 1  containing 2X900GB with Raid 1 for Vmware and Virtual Disk Group 2 containing 4X900 GB with Raid 5. Will this configuration supported  by TAC ? As i read somewhere that if you are not using Cisco guideline on Raid configuration then Cisco TAC support will not provide any support for cases related to server.

In my case as my server is not TRC bases according to you ( which i agree), there should not be any TAC support problem if i use my mentioned raid configuration. Correct ?

If your hardware/configuration is different from the TRC then you are under the Spec-Based guidelines and you are still supported by TAC assuming the Spec-based requirements are met:
