Dell R910 with Integrated PERC H700 Adapter
- by Alex
I am in the process of designing an architecture based around a single Dell R910 server running Windows Server 2008 Enterprise.
I would like the server to have 8 RAID1 pairs of spinning disks, so I intend to implement:
Dell R910 Server
Integrated PERC H700 Adapter with 1 SAS expander on each SAS connector (so 8 expanders in total)
7 RAID1 pairs of 143Gb 15K HDD, each paired on one connector using an expander
1 RAID1 pair of 600Gb 10K HDD, paired on the remaining connector using an expander
My main concern is not to introduce bottlenecks in this architecture, and I have the following questions.
Will the PERC H700 Adapter act as a bottleneck for disk access?
Will using SAS expanders for each RAID1 pair cause a bottleneck or would this be as fast as pairing disks directly attached to the SAS connectors?
Can I mix the disks, as long as the disks in each RAID1 pair are the same? I assume so.
Can anyone recommend any single-to-double SAS Expanders that are known to function well with the H700?
Cheers
