The ODX function offloads the processing load for copying and transferring files from the server CPU to the
storage system.
Space Reclamation
•
The Space Reclamation function automatically releases areas that are no longer used by the OS or applica-
tions.

integrated tool set for the management of applications and services.
SCVMM is a component of System Center 2012 that performs integrated management of virtualized environ-

3.10.4

OpenStack Linkage

ETERNUS OpenStack VolumeDriver is a program that supports linkage between the ETERNUS DX and Open-
Stack.
By using the VolumeDriver for the ETERNUS DX, the ETERNUS DX can be used as a BlockStorage for cinder.
Creating volumes in the ETERNUS DX and assigning created volumes to VM instances can be performed via
an OpenStack standard interface (Horizon).
3.10.5

Logical Volume Manager (LVM)

The Logical Volume Manager is a management function that groups the save areas in multiple drives and
partitions and manages these areas as one logical drive. Adding drives and expanding logical volumes can
be performed without stopping the system. This function can be used on UNIX OSs (includes Linux).
LVM has a snapshot function. This function obtains any logical volume data as a snapshot and saves the
snapshot as a different logical volume.
