September 21, 20205 yr 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!
September 21, 20205 yr 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.
September 21, 20205 yr Author 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.

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.
April 2, 20215 yr 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.

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.
November 27, 20232 yr Author @Heffe there should be an option for "personality mode", it's under that.
