September 29, 20196 yr Hi, I am upgrading to two parity drives and would like to know the best way to do this performance wise please? I have a S3008 with port going direct to the backplane of my 24 disk rackmount serving the first 4 bays and the other going to a RES2SV240 extender serving the other 20 bays. I currently have the parity drive in the first 4 bays port, would I benefit from connecting the 2nd parity to the same port or off the extender or will it not make any difference either way? Many Thanks in advance for any advice!
September 29, 20196 yr Overall won't make different. In your case, I will connect parity under expander.

October 1, 20196 yr With 20+ data drives, and upgrading from one-parity to two-parity, there could be a prior/intervening performance bottleneck. Do you have sufficient (single-core/thread) CPU power? I.e., can you generate enough parity data (fast enough) to justify/validate your stated question? -- "If you push something hard enough, it will fall over." Edited October 1, 20196 yr by UhClem
