Zpool wizard

This function allows you to create pools, that will be named as "zpools".

Pools are used for grouping disks that belong to storages.

1. - CREATE DATA GROUP - provides information of all hard drives that are connected to the storage server. To add first Data Group to your zpool please select disks on the list on the left, select redundancy type and click "Create group" button.

It is also needed, to define to redundancy level for the created group. Available redundancy groups are :

• Single - each disks works as a single drive
• Mirror - All data that are stored on disk "A" will be automatically mirrored on the disk "B". At least two disks are needed for creating a mirror. They need to be the same size.

2. CREATE WRITE LOG - allows to configure the write log function, using a redundancy level (mirror or single drive).

A separate-intent log device. If more than one log device is specified, then writes are load-balanced between devices. Log devices can be mirrored. However, raidz vdev types are not supported for the intent log.

3.CREATE READ CACHE - A device used to cache storage pool data. A cache device cannot be configured as a mirror or raidz group.These devices provide an additional layer of caching between main memory and disk. For read-heavy workload,where the working set size is much larger than what can be cached in main memory, using cache devices allow much more of this working set to be served from low latency media. Using cache devices provides the greatest performance improvement for random read-workloads of mostly static content.
