UCS C series maximum hard drive size

[jebyers]

Looking for info on the maximum hard drive size support on teh UCS C series.  I have a C200M2 that I added a 4TB drive, I have updated the server to the latest firmware and BIOS however the server shows the drive size is 2TB.

Hi!  and welcome to the community mate!

Here is the table that shows the supported disk's PID for the C200 server:

If you successfully installed ONE HDD of 4GB and made it work, you were lucky cause I don't see any disk with that size, I have not even seen a disk of that size for UCS yet.

I am wondering if perhaps you installed 4 disks of 1TB and configured them in RAID 1 which would explain the reason for the size to go down to half of the capacity of the array as RAID 1 is a mirror.

Let me know if I misunderstood you.

Can you clarify a few things

1. What RAID level is this 4TB drive set up for?

- What size and speed are the hard drives? (1 TB 7.2k RPM SATA, 300 GB 10k RPM SAS)

- How many drives are installed in the C200? 

2. What RAID controller is installed on the server? 

3. What do you mean by "server" here? 

- UCS CIMC showing 2 TB? 

- Operating system showing 2 TB? 

4. What operating system is installed on the server?
