Thin provisioned snapshot space and it is writable. Snapshot space sits at the same RAID group of the volume that the snapshot is taken against. Therefore when you expose the snapshot into a virtual disk, it becomes a thin-provisioned Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.
You can set as many as 16 policies for each RAID group. When space usage ratio grows over the threshold set in the policy, the action will be taken and event log will be generated. Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.
Applications that spread metadata across the entire volume will obviate the advantages of thin provisioning. Some applications that expect the data to be contiguous at block level are not good candidates for thin provisioning as well. Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.

LACP packets to the peer. Theoretically, LACP port can be defined as active or passive. Qsan controller implements it as active mode which means that LACP port sends LACP protocol packets automatically. Please notice that using the same configurations between Qsan controller and gigabit switch.

LACP. Otherwise, host cannot connect the link with storage device. Dual Controllers The Qsan storage system supports dual controllers of the same type for redundancy. Controller 1 (CTRL 1) is the master controller and controller 2 (CTRL 2) is the slave by default.
SATA drives are not necessary. The differences between single and degraded are described on the following. There is no error message for inserted one controller only. I/O will not force to write through. And there is no ownership of RAID group. Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.
Snapshot virtual disk is allocated within the same RAID group in which the snapshot is taken, we suggest to reserve 20% of the RAID group size or more for snapshot space. Please refer to the following figure for snapshot concept. Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.
There are two methods to take snapshot. In Virtual Disks tab, selects a virtual disk. And then click ▼ -> Take a Snapshot or in Snapshots tab, click Take a Snapshot button. Enter a Snapshot Name. Click OK button. The snapshot is taken. Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.
There are two methods to cleanup snapshots. In Virtual Disks tab, selects a virtual disk. And then click ▼ -> Cleanup Snapshots or in Snapshots tab, click Cleanup Snapshots button. Click OK to apply. It will delete all snapshots of the virtual disk and release the snapshot space. Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.
00:00. Rollback The data in snapshot can rollback to the original virtual disk. Please follow the procedures. In Snapshots tab, selects a snapshot. And then click ▼ -> Rollback. Click OK to apply. Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.
To avoid this data inconsistent issue between snapshot and original data, user has to make the operating system flush the data from memory of host (write caching) into disk before taking snapshot. Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.

Fast Rebuild TIP: With less changed partition, the Fast Rebuild feature may go faster. If the virtual disk is full of changed partition, the rebuild may take the same time without Fast Rebuild feature. Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.
Thus, the performance of random write in a clean partition would be worse. CAUTION: The fast rebuild should not be enabled for a virtual disk whose access pattern is random write. Copyright@2004~2014 Qsan Technology, Inc. All Rights Reserved.
