Openstack Linkage - Fujitsu ETERNUS DX100 S4 Design Manual

3. SAN Functions
Server Linkage Functions
■
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 notifica-
tion 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.
ETERNUS VSS Hardware Provider is required to use this function.
SnapOPC+ and QuickOPC can be used as the copy method.
To use the ODX function, the controller firmware version of the ETERNUS DX must be
V10L80-2000 or later, or V10L81-2000 or later.
■
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 2016 that performs integrated management of
virtualized environments. The ETERNUS DX can be managed from SCVMM by using the SMI-S func-
tions 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. Creating volumes in the ETERNUS DX and assigning created volumes to VM instances
can be performed via an OpenStack standard interface (Horizon).
