Hey all,
So I'm finally in the process of upgrading my FreeNAS box to a Supermicro 846E16 Chassis which is a 24 drive case (up from my 15 drive case in my signature). This will be the first time I'm working with SAS though.
While I'm still unsure if I will be going with the 120mm fan hack that is available for this case in place of the stock fans (though I did order the SQ power supply version since I got the case barebone and will be migrating my existing motherboard over) the existing motherboard does not have SAS connections on it and for my existing setup, was using a separate SATA card and the onboard SATA. I'm currently using 13 drives but might add 6 more drives as a separate new vdev to the existing pool.
I'm thinking about just getting rid of the SATA card and using the existing two SAS connectors (the backplane is a BPN-SAS2-846EL1 and has two SFF8087 connectors coming from it) into maybe this card (https://www.ebay.com/itm/HP-H220-6G...0-IT-Mode-for-ZFS-FreeNAS-unRAID/162862201664)
This seems fine, however since I have no experience with working with SAS cards, I've been reading that these things can generate a lot of heat and have seen pictures of people adding 40mm fans to the heatsinks to keep them cool.
While I more than likely will just have one of these in the system, is cooling really a huge problem with these cards?
Just in case though, I did see a post that recommended a SFF8087 to 4x SATA breakout if I wanted to use my existing hardware, so I got two of them. However if it's better to go the SAS HBA rout then sure.
