Chapter 1 Overview
■
Cloud Platform
Optimal storage virtualization that supports cloud computing can provide a flexible ICT environment.
The system administrator can assign virtual resources flexibly on an on-demand basis according to operation
load regardless of the physical devices by virtualizing all of the servers and storage systems and setting up a
virtual resource pool.
●
Disk Volume Virtualization
"Thin Provisioning", which is storage capacity virtualization technology, can reduce unused physical disks by
allocating only the required capacity as logical disks. This reduces the operational burden and the initial cost
that is required for upgrading the storage capacity (small start).
The ETERNUS DX has a function that balances writing areas on a volume basis to prevent concentrated access
to a specific RAID group in multiple RAID groups that configure a disk pool.
●
Virtualization Integration
Various functions that are provided by Oracle VM, VMware, and Microsoft are supported to configure and op-
erate virtualized environments.
Linkage with software allows the backup of virtual environments (VMware/Hyper-V) without stopping the vir-
tual machines. A more effective use of resources and the integrated management of virtualized environ-
ments can be achieved by offloading the server load to the ETERNUS DX.
VMware vSphere's Virtual Volumes (VVOLs) that manage volumes for each virtual machine are also suppor-
ted. Finely tuned backup operations and resource management can be achieved according to the operational
requirements for each virtual machine.
■
Operability
By using a virtual environment, the ETERNUS DX is able to utilize its resources more efficiently. In addition,
various connectivity options are provided and integrated storage management is available.
●
Unified Storage
The ETERNUS DX provides SAN and NAS functions and enables a SAN/NAS storage integrated environment.
In a SAN environment, block data transfer is performed via FC, iSCSI, and FCoE.
In a NAS environment, the ETERNUS DX can be used as a file server to transfer file data by using the NFS
protocol and the CIFS protocol via Ethernet.
In addition, by installing ETERNUS SF Storage Cruiser (storage management software), integrated monitoring
of SAN and NAS environments is available.
●
Automated Storage Tiering
The ETERNUS DX supports Automated Storage Tiering. This function detects data access frequency and redis-
tributes data between drives with various drive types according to the policy that is set. The most suitable
cost effective performance can be realized by moving frequently accessed data to high performance SSDs and
less frequently accessed data to cost effective Nearline SAS disks in collaboration with ETERNUS SF Storage
Cruiser. Server settings do not need to be changed after redistribution.
●
Easy Operation Management
Operation management can be easily performed with ETERNUS Web GUI by using a Web browser or with
ETERNUS CLI by using commands and command scripts.
