PowerEdge 6800 drive configuration
My customer has a PowerEdge 6800 rack mounted with PERC 4e/Di RAID Controller, 4GB RAM, Small Business Server 2003 R2. Device manager shows Adaptec 3920A Ultra SCSI Card (Listed twice). Processor is Xeon CPU 3.00GHz (4 entries showing this). The front bezel shows bays 0-3 have green lights and 4-7 show no lights. On the front of 3 of the drive bays is written 73GB 10K Ultra320 SCSI. I assume that this means there are 3x 73GB 10000RPM Utra SCSI drives behind these labelled bays.
The Windows Disk Management shows only a single Drive 0 with a Drive C of 12GB, a drive D of 192GB and drive E of 16GB. C & D are coloured blue (ie Primary Partitions).
I am trying to work out whether there ARE 3 drives and if there is any RAID set up. My ignorance says if there are 3 drives, why don't they show in Disk Management as 3 drives? - unless the RAID controller 'camouflages' them. Then my ignorance says if they are RAID 5, why doesn't Disk Management show 66% of the total drive space (ie 73GB + 73GB = 146GB and 73GB lost to parity)? Any ideas what I actually have? Are there 4 processors present? Are there 2 SCSI cards present? Thanks guys.

If you boot the server you can see how many and what the processors are, it will show you can see how many scsi adapters and you can go into the raid configuration program and view the actual config and the drives. DO NOT CLEAR it but you can just view it. So if you can find some down time to reboot the server you can see everything you are asking about.
