ZFS esxi: auto tier, snapping service, scrubbing service ...?
Posted on 2013-01-06
Hi,
I see Nexenta ZFS has a lot of "services", as mentioned in this title and below in screenshot.
How should I configure them best practice?
Auto tier? Can do it locally or remotely, I guess that's also some kind of backup?
Snapping? Understand what it can do but I have the option to snap every hour(?!), won't impact be drastic on performance and where does it keep the data (I'd need massive extra storage right)?
Scrubbing? Here I have the option to do this weekly by default?

Best Practices: Using NexentaStor for VMware Customers
Auto-Tier = Incremental File-Level Snapshot Backups.
Snapping = ZFS Snapshots are kept in the ZFS volume, so yes, your storage will be used, if you decide to use Snapshots for Restore.
Scrubbing = ZFS Scrubs allows you to schedule and manage scrubs on a ZFS volume. Performing a ZFS scrub on a regular basis helps to identify data integrity problems, detect silent data corruptions caused by transient hardware issues, and to provide early alerts to disk failures. If you have consumer-quality drives, consider a weekly scrubbing schedule. If you have datacenter-quality drives, consider a monthly scrubbing schedule.

*Auto tier isn't relevant here to activate then?
*By default snapping shows option for every hour. What would you recommend + will it impact performance heavily?
*Scrubbing: ok, I'll activate it once a week
