hawihoney Posted January 9, 2019 Share Posted January 9, 2019 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 Quote Link to comment

hawihoney Posted January 9, 2019 Author Share Posted January 9, 2019 Thanks. My MB does not support bifurcation. Do you think two of these PCIe adapter cards with one M-key M.2 per card would work? Quote Link to comment
JorgeB Posted January 9, 2019 Share Posted January 9, 2019 Yes, you can get something like this: https://www.amazon.com/Lycom-DT-120-PCIe-Adapter-Support/dp/B00MYCQP38 Quote Link to comment
hawihoney Posted January 10, 2019 Author Share Posted January 10, 2019 Did order two of these cards plus two Samsung 970 EVO to build up a cache pool. Will report. Quote Link to comment
tjb_altf4 Posted January 10, 2019 Share Posted January 10, 2019 (edited) Should work, I used one of the HyperX PCIe M.2 SSDs in my previous unraid build (x58 board), which has this kind of adaptor. Edited January 10, 2019 by tjb_altf4 Quote Link to comment
