Good idea? Dell MD1000 with 3TB SAS drives using a PERC 6/e controller to attach to a PowerEdge R905.

Do I need interposers if I only put SAS drives in there? I was under the impression this was not needed for a SAS only configuration.

Can anyone comment on putting Enterprise grade Seagate Constellation 3TB SAS disks in RAID6 mode in this direct attached storage solution?
