rattlehead05 Posted September 21, 2020 Share Posted September 21, 2020 Hi all! I got my hands on a LSI Megaraid 9460-16i card recently, and it supports 1xNVME/4xSAS/4xSATA on each of its 4x SFF-8643 connectors. I was thinking of using a pair of NVME disks for a mirror cache pool, and using the remaining 8x SAS/SATA connections for my storage pool, like what's shown in the picture but with SATA disks. Is there any reason this would give me issues? I have never used NVME before, and know SSD's are not recommended for the storage pool disks. Thanks! Quote Link to comment
JorgeB Posted September 21, 2020 Share Posted September 21, 2020 That's a RAID controller, better option would be the 9400-16i, doesn't mean it won't work, just that's it's not recommended. Quote Link to comment
rattlehead05 Posted September 21, 2020 Author Share Posted September 21, 2020 It's got a software switch to change it to "JBOD Mode". Plus I got it for free from a machine that was getting scrapped, so it's the card I have haha. Quote Link to comment

The card itself is fine, unfortunately it doesn't support NVME with the cables, it requires a backplane with come circuitry. I have been using 2x SAS 12Gbps Seagate ssd's for cache drives, and it's been just fine. Quote Link to comment
dlbogdan Posted April 2, 2021 Share Posted April 2, 2021 A bit late but, to use NVMe drives (U.2) with that card you need special U.2 Enabler cables from Broadcom. Go and have a look on their site. Quote Link to comment

My work was throwing out a Dell Precision 5820 and it has this card in it...…how do you turn the disk into JBOD mode? I can't seem to find any info on it. Quote Link to comment
rattlehead05 Posted November 27, 2023 Author Share Posted November 27, 2023 @Heffe there should be an option for "personality mode", it's under that. Quote Link to comment
