I don't think I've ever seen any SAS drives that actually have jumpers. Any drive is supported for raid 5 (it's not a feature of a drive, but of the raid controller). Some drives are raid certified as such, but if it's a SAS drive, that's automatically the case. If you don't have the need to keep data, you can just shut down the server, pull the 3 x 146, put in 3 x 300, power up and use the PERC bios to create a raid 5 with the 300GB drives.
Hi All, I have a dell poweredge 1900 tower with three TN937 146GB 15K SAS 3.5" HD's.  Are these drives a straight swap with Dell HT954 300GB 15K SAS 3.5 HD's? Is there anything to configure on the drives before installation in terms of jumpers? Are the HT954 Hard drives supported by raid 5? Thanks for any info in advance, or even links to information.
