Chapter 1 Overview
■ Operability
●
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.
●
Virtualized environment integration
Various functions that are provided by Oracle VM, VMware, and Microsoft are supported to configure and
operate virtualized environments.
A more effective use of resources and the integrated management of virtualized environments can be
achieved by offloading the server load to the ETERNUS DX Disk storage system in collaboration with
servers.
●
Storage virtualization
Virtualization technology enables a larger capacity than the physical disk capacity to be shown to the
server. Multiple physical disks are collectively managed as a disk pool and the necessary capacity is flexibly
allocated according to write requests from the server.
The ETERNUS DX Disk storage system 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.
●
Automatic layering
The ETERNUS DX Disk storage system supports automatic storage layering. This function detects data
access frequency and redistributes 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 disks in
collaboration with ETERNUS SF Storage Cruiser. Server settings do not need to be changed after
redistribution.
●
Connectivity
OSes such as UNIX, Linux, Windows, and VMware are supported. The ETERNUS DX Disk storage system can
be connected to various UNIX servers and industry standard servers by Non-Fujitsu manufacturers as well
as Fujitsu servers such as PRIMEQUEST and PRIMERGY.
●
Backup
Data can be replicated at any point with high speed by using the Advanced Copy functions in conjunction
with software such as ETERNUS SF Advanced Copy Manager.
Data can be replicated between multiple ETERNUS DX Disk storage systems without affecting the
performance of the server by using the remote copy functions.
●
Stabilization of processing performance
When loads from one application are high in a storage integrated environment and sufficient resources to
process other operations cannot be secured, performance may be reduced remarkably.
The QoS (*5) function can be used to stabilize performance by setting the load upper limit for each
application to secure the processing performance of the server that needs to be processed preferentially so
that workload fluctuations do not affect other applications.
*5: Quality of Service
