Hello!
Please, need some advice about the best way to configure 9x4TB HDs for my needs. My use of the pool would be:
- I'm working directly with the files (shared with NFS), so really need the best possible random RW speed. The server and the (unique) client are connected by 10GBe
- My storage requirements are only of about 10TB
So, I'm thinking this:
plus:
The idea is to work directly with the files in 'pool', and configure 'pool-backup' in FreeNAS as a replication of 'pool', with a frequent snapshot policy (commented at the end).
Others (more simple) alternatives would be, always looking for the best random RW speed, maybe:
or:
For backups, I'm thinking of NOT to use an external backup system and rely entirely in snapshots. In reallity, in a very agressive periodic snapshot policy, very frequent. Something like:
- Periodic snapshot 'pool' every 5 minutes, with 2 day lifetime
- Periodic snapshot 'pool' every 1 day, with 15 day lifetime
- Periodic snapshot 'pool' every 1 week, with 2 month lifetime
What do you think? Is this reasonable? Please, comments, advices, THANKS!!
