Dell PowerEdge 2950 SAS to SATA
Hello,
I just received my Dell PowerEdge that came with (3x) 147GB SAS drives in a RAID 5 configuration. I would like to replace the SAS drives with SATA drives but am not sure what this involves besides getting the drives.
Can someone share some experiences and/or suggestions on how to move forward.
Thanks.

So if you want to 'migrate' from SAS drives to SATA drives, you'll need to back up your data (e.g. tape, network share, etc), remove the SAS drives, put in the SATA drives and create a new raid container (keep it below 2TB as you won't be able to go beyond 2TB (usable) and boot to the disk). Reason for this is that virtual disks over 2TB will have to be converted to GPT instead of MBR (supported by Windows 2003 SP1 and later and by Linux with the 2.6 kernel (so no support by Windows 2000, XP, VMware ESX, Netware)) and you cannot boot to GPT disks (a bios cannot boot to a GPT disk, instead you'd need an EFI, which is only used on the Dell Poweredge servers that use Itanium processors).
If you're wanting to set up 3 750GB SATA drives in a raid 5, don't worry about the GPT/2TB part of my post, as 3x750GB in raid 5 yields about 1380GB or so of usable disk space. Even 3 x 1TB drives doesn't go beyond 2TB. However, if for some reason you want to set up a raid 0 (would strongly recommend against this on any production servers), you'll need to keep the 2TB limit in mind.

This whole business of deliberately withholding certain parts so that you have to pay grossly inflated prices for something you could get elsewhere for about half the price, is really annoying. At the end of the day I'll probably spend more because of the time I'm having to invest in this versus just bending over the log and getting it over with, but at least Dell won't get rewarded for trying to hold me hostage.

Interposer board NOT required.
Bought the caddy and boards just in case, but tested without and they work perfectly fine.
The caddy has a screw slot further back, use this.
P.s. I now how 6 interposer boards available!
