hotswap - Are all SAS drives hot-swappable?




Can get a 300GB Cheetah 15K SAS 3.5 disk for quite a bit cheaper through another supplier vs. Dell's out-of-warranty depot (for an aging PowerEdge server). Specs are identical, wondering if there's any difference that I'm not seeing as far as hot-swappability (<-- just made that up).



Assuming it's more of the controller/connector vs. the drive?


Answer



Yes, they're hot-swappable...



The drives are usually compatible and the hot-swap ability is built into the SAS specification. The SFF-8482 connector on the drives is a standard and there's nothing physically unique to Dell drives versus the OEM.



I'd still prefer to use the manufacturer drive part number before going OEM, though. If you dig a bit harder (eBay, refurbished, liquidators), you'll be able to find the Dell-specific drive you need at or below the cost of the OEM.
