樓主留意哦, 塊server board似乎唔支援PCIe M.2 SSD RAID.

P.62 (6.2.1.1)有講.

P.61說可以兩個M.2行ERST RAID

P.62說可以四個PCIE行RST RAID

但不能U.2

P.61 ERST 祗 for SATA mode(<600MB/s), PCIe mode唔得
P.62 PCIe行RST RAID要駁 OcuLink

暫時知道以下兩種方案可行到RAID10.
(1)SATA mode:
8x 500GB(or 4x 1TB) SATA SSD 行RAID10
(2)PCIe mode:
4x 1TB U.2 NVMe 1TB 行RAID10
要另買OcuLink Cable x 4, VROC(Virtual RAID on Chip) Upgrade Key(P.65-67)

同埋留意兩個M.2喺PCIe mode係唔等速的, 一個PCIe x4, 一個PCIe x2 (P.62, Figure 28). 唔知係咪呢個原因PCIe mode行唔到RAID.

咁我可以買四個P4800X加OCULINK就可以RAID10 PCIE???

同埋呢個係部server嘅 Hot Swap Backplane

睇到有8 x OcuLink connectors, 2 x miniSAS connectors

睇spec應冇問題.

除了買oculink cable仲要買upgrade key(p.66-67)

RAid10可能唔得. 我睇漏左4個oculink分別屬兩粒cpu.
CPU_1: Oculink_0, Oculink_1
CPU_2: Oculink_2, Oculink_3
有文話BOOTABLE raid唔可以across CPUs. 所以on-board Oculink衹可行RAID 0,1

要行PCIE RAID10就要考慮呢D方案了

但要留意，暫時衹知張卡支援intel ssd.

算不算SOFTWARE RAID10就可以?

好像用MDADM可以四隻P4800X RAID0
