KERNSAFE - iSCSI SAN Software and Storage Virtualization

After create a storage pool, user need to create volume to use the storage pool, while creating volumes, use can choose whether to create iSCSI target or not.

Choose Storage Pool, to create volume from which pool.

Input Volume Name

Specify Capacity

Specify Quota, Note, Quota is used for saving additional data of the volume, for example, the volume create a snapshot, it may use double times (maximum) of the space, but more snapshots more space will need. Furthermore, for Log Structured Volume, need around 20% more space even no creating snapshots.

Specify Volume Type, currently we support three volume type: RAW, Thin Provisioning and Log Structured.

RAW will use the static allocated space crossing multiple devices, it is fastest but not support to create snapshot.

Thin Provisioning is dynamically allocating space while using, it supports unlimited zero-copy snapshots, and it is same performance after all data allocated.

Log Structured is almost the same as Thin Provisioning, but all data writing is sequential, it is write optimizing for HDDs.
