I've seen estimates for anywhere from 0.3% to 1.6% for metadata, so I'm just trying to get the sizing nailed down before ordering. The other concern is the metadata is only mirrored with this provisional setup. Thoughts about risk?
We have been using 36-bay Supermicro boxes for a while and are happy with them, but for the latest pair of FreeNAS boxes we are looking at the 6049P-E1CR45L+ due to its larger capacity and optional NVMe storage. My big question is with the hybrid storage pools available with TrueNAS CORE, how much SSD space will I need for a metadata VDEV if I have 5 9-wide RAIDZ2 VDEVs? These systems will primarily be used for Veeam backups but will also be hosting misc NFS and iSCSI storage. Thanks in advance!
Provisional storage layout:
45 x 16tb Nearline SAS
768gb memory
2 x 240gb s4510 SATA drives (OS)
2 x 2tb p4510 NVMe (L2ARC)
2 x 375gb Optane NVMe (SLOG)
2 x 7.6tb NVMe (metadata)
