2.3 600 GB FC disk drive module
The DS5000 offers a 600 GB FC enhanced disk drive module (E-DDM). The dual port FC
DDM operates at 4 Gbps FC speed. It is designed to fit into the EXP810, EXP5000, and
EXP520. However, the drive requires a certain enclosure service module (ESM) firmware and
controller firmware (CFW) version to be recognized by the DS5000 subsystem. See the latest
ESM readme to verify compatibility with your subsystem.
The drive is also available as an FDE Drive.
The DDM characteristics are:
600 GB capacity
15,000 RPM (15K)
Hot swappable
Dual FC interface to EXP
2.4 1 TB SATA enhanced disk drive module
The DS5000 offers a 1000 GB (1 TB) SATA enhanced disk drive module (E-DDM). The disk
drive operates at 3 Gbps SATA speed. The ATA interposer card on the DDM converts the ATA
protocol of the drive to the 2 or 4 Gbps Fibre Channel protocol, so that the DDM module fits in
every EXP810, EXP5000, and EXP520. However, the drive requires a certain enclosure
service module (ESM) firmware and controller firmware version (CFW) to be recognized by
the DS5000 subsystem. See the latest ESM readme to verify the compatibility with your
subsystem.
The DDM characteristics are:
1000 GB capacity
7200 RPM
Hot swappable
Dual FC interface to EXP
2 and 4 Gbps FC speed
2.5 IBM System Storage DS5020 storage subsystem and
EXP520
The IBM System Storage DS5020 storage system (Machine Type 1814-20A) is designed to
provide solutions to meet the needs of midrange/departmental storage requirements,
delivering high performance, advanced function, high availability, modular and scalable
storage capacity. It also provides SAN-attached 8 Gbps Fibre Channel (FC) and 1 Gbps
iSCSI connectivity, and support for RAID levels 0, 1, 3, 5, and 6 up to over 49 terabytes (TB)
when using 450 GB Fibre Channel hard drives and up to 112 TB when using 1 TB Serial
Advanced Technology Attachment (SATA) Enhanced Disk Drive Modules (E-DDMs).
