RAID Configuration Suggestion - Help, please

I have a new Prolaint ML 350 Gen9 with 8 x 300 GB SAS HDD using the onboard Smart Array P440ar controller.  It's more storage than we require (nice bonus) so I would like to take advantage of RAID 1+0.

 

Which would be better? Reliability, Redundancy, & Performance are my priorities.

Windows Server 2012 R2 will be on the system drive, and we'll be using two Hyper-V servers.

 

Option 1

8 x 300 in RAID 10 = 1200 GB, then use Windows Disk Management to partition into 300 & 900 GB drives.

 

Option 2

2 x 300 in  RAID 1 =  300 GB

6 x 300 in RAID 10 = 900 GB

 

 

Any other suggestions?

Is the onboard RAID powerful enough for this?  Our vendor said it was.

 

Thanks,

- Ken

Hi,

 

I would go with Option 2.

 

Option 3 would be to create the following:

2 x 300 in  RAID 1 =  300 GB

5 x 300 in RAID 10 = 900 GB

1 x 300 as global online spare.

 

Refer to QuickSpecs of P440ar.

 

Fault Recovery

On-Line Spares: There is no limit to the number of spare drives that can be installed prior to drive failure. If a failure occurs, recovery begins with an On-Line Spare and data is reconstructed automatically.
