2 x Intel Xeon Gold 6148F 20C40T 2.4GHz US$6,454
2 x Intel Passive/Active Combination Heat-Sink BXSTS300C US$86
1 x Intel 2U Server R2312WFTZS US$2,599
24 x Kingston KSM26RD4/32HAI 32GB DDR4-2666 ECC US$8,913
2 x Intel Data Center P4800X 375GB HHHL NVMe PCIe 3.0x4 SSD US$3,040
1 x APC BACK-UPS Pro 1000VA BR1000G US$180

Questions:
1) Is the RAM compatible with this motherboard?
2) I am planning to run RAID0 for my SSD. Can the onboard RAID turn two SSDs into RAID10 also?
3) What are the benefits of APC SMART-UPS RT ON-LINE 1000VA 2U Rackmount SURT1000RMXL2U US$920 over the current UPS choice? My goal is to run long enough for a clean shutdown. Is BACK-UPS Pro enough?
4) I might add an Nvidia NVLink card later. Does this motherboard supports NVLink? If not, is there an add-on to make it work?

Thanks a lot in advance!
