Norco backplane safety

Featured Replies

I have a NORCO 4220 with backplane version SAS 3505 version 3.5.   I have read multiple reports of poor MOSFET quality on certain versions of the backplane not being able to support the current of newer drives.

I previously had this backplane functioning with 1TB drives, fully populated, but I now wish to use it with 8TB drives, and need to understand if It will damage the drives and/or the backplane.

 

Anyone have evidence or response from Norco (already emailed them) about which versions of the backplane are susceptible to damage?

I'd wait for a response from Norco. I don't recall which backplane version I have - but mine is fully populated with 24 8tb drives and I have been able to hot swap without any damage to any drives or the backplanes. Mine use a single 4 pin molex power cable each. I know there were variants with SATA, and dual 4 pin molex prior to mine. I bought the case ~4 years ago now.

Mine has two molex'es per backplane, and a single miniSAS that addresses the whole backplane  (which is really nice cause my controller has that too, so less cables)
