If you have a poweredge 2950, then you have a perc 5 card, no doubt. If your internal drive slots (front of the machine) are all maxed out, I think you need to buy another perc card to control something external.
I don't think fibre channel is in use for these, unless you were to use some sort of SAN. In which case, I'm sure you have no choice about underlying hardware. If you're buying DAS from dell, I think your choices are SATA vs SAS. For a small number of disks, there are performance improvements with SAS, but if you're putting a whole bunch of disks into an array together, both the SATA and SAS disks will max out the 3Gb bus. So then you might as well save the money and go with SATA. That's what I do, and that's what I recommend. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Scott Ehrlich > Sent: Monday, August 20, 2007 4:23 PM > To: [email protected] > Subject: [BBLISA] RAID storage - SATA, SCSI, or Fibre Channel? > > I have a Dell PowerEdge 2950 and am looking to add more > storage.
