I Keep on having problem where The Server Keeps freezing, at this point i only could point finger to instability to the RAID card, so i would like to replace it with something else that could handle 16 HHDs.
I’ve been using LSI/3ware cards for years without issues. Only “issues” I’ve encountered is that not all of them will allow direct pass through to FreeNAS, but that’s not their fault. That said, I haven’t worked with anything newer than 9560 cards, everything since has just been an onboard controller for JBOD to FreeNAS.
The newer LSI cards have RAID 5 or RAID 6 built into the hardware. I’ve never had any throughput issues, and as far as I know, AVID technologies still uses LSI cards in their video servers. You may also want to get the battery backup module.
Again, just my personal use cases have directed me to this brand.
And you may want to get a 24 or 32 drive card so you can expand to a second/bigger chassis if you need more drives. Most of these will break out with a multi-lane cable of some sort.
