High Reliability - Fujitsu ETERNUS DX60 S3 Overview Manual

Chapter 1 Overview
●
Cache capacity
The cache memory capacity for each controller is 2GB.
●
Model Upgrade
As a support for system scalability after installation, an ETERNUS DX can be upgraded to a higher-end model.
The ETERNUS DX60 S3 can be upgraded to the ETERNUS DX100 S3 .
■

High Reliability

The high reliability of the ETERNUS DX enables operations to continue even when hardware fails. The ETER-
NUS DX also protects data and provides high speed data access.
●
Data Integrity
The ETERNUS DX adds check codes to all data that is saved. The data is verified at multiple checkpoints on
transmission paths to ensure data integrity.
●
Monitoring for Signs of Failure
When a sign of potential drive failure is detected, the data from the suspected drive is restored to the hot
spare. When the restoration is complete, the hot spare is switched for the drive with a possible sign of drive
failure.
●
Fast Recovery
A RAID level (RAID6-FR) that reduces data recovery times by supporting high speed recovery.
■
Security
Security and compliance are essential for the globalization of business activities and for the company's re-
sponsibility in society.
Support of Secure Socket Layer (SSL) and Secure Shell (SSH), which enable encryption of the network data
that is transferred between the ETERNUS DX and the operation terminals, prevents any fraudulent access,
alteration, and information leakage from occurring.
■
Cloud Platform
Optimal storage virtualization that supports cloud computing can provide a flexible ICT environment.
The system administrator can assign virtual disks 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 virtu-
al 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).
