1. Overview
●
Host Interfaces
SAN host interfaces can be selected from FC 16Gbit/s, FC 8Gbit/s, iSCSI 10Gbit/s, iSCSI 1Gbit/s, and FCoE 10Gbit/s.
Up to 16 ports can be installed in a single ETERNUS DX500 S3 and up to 32 ports can be installed in a single
ETERNUS DX600 S3.
NAS host interface can be selected from Ethernet 10Gbit/s and Ethernet 1Gbit/s. Up to 16 ports can be installed
in a single ETERNUS DX500 S3 and up to 32 ports can be installed in a single ETERNUS DX600 S3.
Different types of host interfaces can exist together in the same ETERNUS DX.
●
Cache Capacity
The installable cache memory capacity when the storage system is used as a SAN storage system is up to 64GB
for the ETERNUS DX500 S3 and up to 128GB for the ETERNUS DX600 S3.
●
Model Upgrade
As a support for system scalability after installation, an ETERNUS DX can be upgraded to a higher-end model.
The ETERNUS DX500 S3 can be upgraded to the ETERNUS DX600 S3.
■
High Reliability
The high reliability of the ETERNUS DX enables operations to continue even when hardware fails. The ETERNUS
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 trans-
mission paths to ensure data integrity.
In addition, the T10-DIF function (*2) is supported. The check codes are generated and the data integrity are
checked in the transmission path to the servers in order to verify data. By linking the Data Integrity Extensions
(DIX) function of Oracle DB, data integrity can be ensured in the entire system including the server.
*2: T10-Data Integrity Field. SCSI specifications related to the data protection mechanism set by T10, a Techni-
cal Committee that manages SCSI standards.
●
Pro-Active Monitoring
When a sign of potential drive failure is detected, the data from the suspected drive is restored to the hot spare.
When the restore is complete, the hot spare is switched for the drive with a possible sign of drive failure.
●
Improved Connection Path Availability
Availability for data transfer paths between controllers and drives is now better than older models. Even if an
error occurs in a drive enclosure on a path, reverse cabling ensures continued access by using normal paths to
minimize the effect of the affected areas.
●
Fast Recovery
A RAID level (RAID6-FR) that reduces data recovery times by supporting high speed recovery.
