Looking for suggestions around mixing 3Gb and 6Gb SAS shelves. Currently have a dual controller FAS2240 with a separate SAS and SATA shelf with 6Gb SAS. I have another 3Gb, DS4243 15k SAS shelf which I would like to add to the 2240. I know this will reduce the SAS speed down to 3Gb. Is this a bad idea? Am I likely to suffer a performance hit?
You are allowed to have one transition between 3Gbit & 6Gbit modules within the same stack. In theory performance shouldn't suffer in most circumstances, however some people were saying they had problems.
