I was looking to buy a few Dell servers and install xcp-ng on them and use local storage to run some VM’s
The spec of the servers is this.
Dell R740XD 2U Rackmount Server
24 x 2.5” NVMe Chassis
Dual x Intel Xeon 6240C 2.6GHz 18C/36T CPU
256Gb DDR4 Ram
10 x 1.6TB NVMe SSD
Dell PERC S140 OB Raid Controller
Broadcom 57416 DP 1GB/ DP 10GB Nic
For all previous kit we setup either spinning or SSD drives to use RAID 50 but the S140 doesn’t support anything other than RAID 1 and I’m being told that using RAID will kill the performance of the nvme drives. Does a raid card exist that does this that I’m missing.
What configuration would you run this in so that we can survive a disk failure without killing everthing. Lots of RAID 1 groups seems a bit sill as well. Any recommended reading or vidoes on nvme and RAID ?
