Hello Community,
Can i get Propositions about a VDEV Layout…
Available Disks:
22 2,4 TB SAS 10k Drives
2 1,92 TB SATA SSDs
2 128 GB NVME Drives
Server should have a good Balance between Redundancy and Speed.
Its “only” for Nextcloud and Network Storage
Thought to go with 3 raidz2 7 wide, one Spare
the NVMEs in Mirror for LOG
the SSDs for Cache.
Is think im not completly wrong with the Config, or am i?
Danke für die Unterstützung! ;
Are you using block storage? I.e. iSCSI or NFS for VMs? If it’s really only Nextcloud, an SLOG will be of absolutely no use.
EDIT: similarly a cache (L2ARC) vdev might actually degrade performance depending on the amount of memory the system has got. How much are you planning?
I’d consider a separate mirrored SSD pool and place the database on that. Perform hourly snapshots and replication to the HDD pool.
With 7 wide vdevs I would also consider RAIDZ3. Then again with the small drives you are using 4x 5 wide RAIDZ1 with two spares will give better performance with moderate risk.
Thank you for the Hint to go with two Pools,
i was so fixed on one Config.
ill go with the raidz1 Version.
