Windows Server
The ETERNUS DX supports the following functions in Windows Server.
•
Offloaded Data Transfer (ODX)
The ODX function of Windows Server 2012
or later offloads the processing load for copying and transferring
files from the CPU of the server to the storage system.
•
Thin Provisioning Space Reclamation
The Thin Provisioning Space Reclamation function of Windows Server 2012 or later automatically releases
areas in the storage system that are no longer used by the OS or applications. A notification function for the
host is provided when the amount of allocated blocks of the TPV reaches the threshold.
•
Hyper-V
Hyper-V is virtualization software for Windows Server.
By using the Hyper-V virtualized Fibre Channel, direct access to the SAN environment from a guest OS can be
performed. The volumes in the ETERNUS DX can be directly recognized and mounted from the guest OS.
•
Volume Shadow Copy Service (VSS)
VSS is performed in combination with the backup software and the server applications that are compatible
with Windows Server VSS while online backups are performed via the Advanced Copy function for the ETERNUS
DX.

System Center Virtual Machine Manager (SCVMM)
System Center is a platform to manage operations of data centers and clouds. This platform also provides an
integrated tool set for the management of applications and services.
SCVMM is a component of System Center 2012 or later that performs integrated management of virtualized envi-
ronments. The ETERNUS DX can be managed from SCVMM by using the SMI-S functions of the ETERNUS DX.
OpenStack Linkage
ETERNUS OpenStack VolumeDriver is a program that supports linkage between the ETERNUS DX and OpenStack.
By using the VolumeDriver for the ETERNUS DX, the ETERNUS DX
can be used as a Block Storage for cinder. Creat-
ing volumes in the ETERNUS DX and assigning created volumes to VM instances can be performed via an Open-
Stack standard interface (Horizon).
Logical Volume Manager (LVM)
The Logical Volume Manager is a management function that groups the save areas in multiple drives and parti-
tions and manages these areas as one logical drive. Adding drives and expanding logical volumes can be per-
formed 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 snap-
shot as a different logical volume.
