Flexible Volume 

Allocation

HDD Management

QTS 4.1.2 allows creating multiple volumes 
on the Storage Pool for various applications 
in typical business environments with 
different workgroups. Each data volume and 
LUN can be extended without interrupting 
services.

IT administrators can view the HDD 
information to check the HDD allocation 
status for RAID group. With the information, 
it can be ensured that there is no idle HDD 
for the maximized utilization of the storage 
resources.

Efficiently use storage spaces with incremental allocation.

Allocate all spaces specified and they cannot be used by other 
volumes or LUNs.

Thin provisioning

Over-allocation allows a server to view more 
storage capacity than has been allocated in the 
storage pool. Furthermore, the  physical storage 
capacity is used only when files are written by the 
application, thereby improving utilization rates.

Thick provisioning

The physical storage capacity is dedicated up front when 
the storage volume is initially allocated.

Storage Pool

IT administrators can aggregate multiple 
RAID groups into a big storage pool to 
flexibly utilize the storage capacity as a 
whole, protect them using redundancy 
and allowing for better protection against 
multiple disk failures for large-capacity 
environments. Multiple volumes can now 
be created on the Storage Pool to provide 
flexible deployment.
