Overview

The ETERNUS DX is a family of storage systems that utilize common software and provide block storage and, with some models, file access. The current hardware models are designated by a generation number, with S5 being the latest generation. There are a number of different models in the DX family as listed:

High-End Enterprise
• DX8900 S4 – 2 to 24 controllers, block access
• DX8700 S3 – 2 to 8 controllers, block access

Midrange Enterprise
• DX900 S5 – 2 to 4 controllers, block access
• DX600 S5 – dual controllers, block and file access
• DX500 S5 – dual controllers, block and file access

Entry Enterprise
• DX200 S5 – dual controllers, block and file access
• DX100 S5– dual controllers, block and file access
• DX60 S5 – dual controllers, block access

The Fujitsu ETERNUS DX family of storage systems are designed for enterprise and distributed environments requiring high reliability, availability and serviceability features. The family of ETERNUS DX systems varies in scale of the number of controllers, capacity, and interfaces.

The ETERNUS systems support connectivity via FC, iSCSI, SAS, or FCoE for block mode and Ethernet for file access. The systems vary in the size of the enclosure for the base unit with additional 2U expansion trays for 2.5” or 3.5” devices and a high-density 4U enclosure.

With the S3 and S4 generation of ETERNUS DX systems, Fujitsu offers extended cache beyond the DRAM cache using PCIe flash cards installed in the system. The S5 generation added support for NVMe cache devices. Up to 25.6 TB, 51.2 TB for the DX900, or 307.2 TB for the DX8900 of flash cache called Extreme Cache is supported. The S4 generation moved to the next generation of Intel processors and added larger capacity device support. The S5 generation followed this trend, adding more processing power and system memory.

The Fujitsu DX line of systems share hardware and software features across the lineup, with higher end systems typically offering more cache, ports and total capacity. Common elements include drive trays, management GUIs and support for replication between systems.

The ETERNUS Snapshot Manager uses CommVault IntelliSnap technology to create periodic snapshots and maintain a catalog of all snaps for near real-time recovery of data.

Additional cost items include support for local copies and mirrors, as well as remote replication and advanced management software options.
