Hi All,
I'm in the process of setting up a new system as a backup storage for Veeam.
Supermicro SSG-640P-E1CR36L, CPU Xeon Gold 6326 CPU 2.9GHz 16C, 256 GB RAM ECC, 4x 10GE NICs
OS disks 2x SSD (mirrored by TrueNAS setup)
DATA disks 22x HDD 20 TB (each vDev by 6 disks RAIDz2, plus hotspares)
CACHE 2x Intel SSD/P5520 3.84TB U.2
I'm looking for suggestions to setup the ZFS filesystem to reach the maximum performance writing backup data through S3 (Minio).
Veeam Backup and Replication V12 is set to write 1MB data chunks as default, but can be tuned.
an then...
Regards.
Stefano

- It is safe to use a single P5520 as SLOG?
- May I use a TrueNAS to manage the mirroring of the P5520s to provide redundancy, or better use VROC?
- Do I need to change the tunable vfs.zfs.dirty_data_max_max ?
- There are other tunables to consirer?
- It's better to set the volume Sync policy to Disabled?
- Do I need to change the Record Size to fit Veeam settings? And S3 is going to change the data block size?
- Better to turn off LZ4?
Regards.
