Would like to add 2x M.2 SSD as cache. How?


Recommended Posts

I just bought a used storage system. This is populated with 24 drives. What I forgot: I need two additional cache devices. What's the best solution?

 

Cables in this system are hand-crafted and fit perfect. So there's no room to add additional power plugs. I was thinking about a PCIe 3.0 M.2 riser card because this MB has plenty of PCIe 3.0 x16, x8 and x4 slots free.

 

For two SATA SSDs I would need to redo the cabeling completely or bring additional external power into that case.

 

Is there a PCIe M.2 adapter with two M.2 slots that will work with Unraid?

 

Many thanks in advance.

 

Case: Supermicro SC846E16
Backplane: BPN-SAS2-846EL1
MB: Supermicro X9DRi-F Dual LGA 2011
CPU: 2x Intel Xeon E5-2609 V2 4 Core
RAM: 64GB DDR3 ECC REG (4 x 16GB)
HBA: LSI 9300-8i
