Chapter 3. IBM System Storage DS4000 and DS5000 hardware 99
As part of the base machine functionality, the DS5000 controllers and EXP5000 are designed
to support integration and use of up to 448 high-performance Fibre Channel or high-capacity
SATA disk drive modules (DDMs).
When configuring more than 48 SATA DDMs on the DS5000 controllers and EXP5000s, one
or more SATA Disk Drive Attachment features need to be selected to maintain entitlement and
support. The SATA Disk Drive Attachment features have been withdrawn from market as of
January 2009. Customers are now entitled to attach as many SATA drives as they want, up to
the maximum of 448 drives.
3.9.1 EXP5000 and EXP520 Storage Expansion Unit
The EXP5000 (1818-D1A) and EXP520 (1814-52A) Storage Expansion Units are each
packaged in a 3U rack-mountable, high-capacity 16-drive bay enclosure containing dual
switched 4 Gbps ESMs, dual power supplies, and redundant cooling. EXP5000s connect to
DS5100 and DS5300 controllers through high-speed 4 Gbps FC disk expansion ports and
have a physical storage capacity of up to 16 TB per enclosure, using 1000 GB SATA DDMs
(disk drive modules) and up to 9.6 TB per enclosure, using 600 GB FC DDMs. It is also
possible to mix SATA and FC drives in the same enclosure. The EXP520 uses the same disk
types and sizes, but only connects to DS5020 storage controllers.
The EXP5000 Expansion Unit (1818-D1A) and EXP520 (1814-52A) base model includes a
3U, rack-mount 16-bay disk enclosure, two software SFP transceivers, dual power supplies,
redundant cooling, rack mounting rails, softcopy documentation, and two rack PDU power
cords (36L8886). Any country-specific wall outlet power cord is obtained through feature
number 98xx.
Both expansion units support the following drives:
146.8 GB, FC 4 Gbps, 15000 rpm (FDE and non-FDE)
300 GB, FC 4 Gbps, 15000 rpm (FDE and non-FDE)
450 GB, FC 4 Gbps, 15000 rpm (FDE and non-FDE)
600 GB, FC 4Gbps, 15000 rpm (FDE and non-FDE)
750 GB, SATA, 7200 rpm
1000 GB, SATA, 7200 rpm
76 GB, FC, solid state drive (only in EXP5000)
