2.1 DS3000 products
The IBM System Storage DS3000 is a family of storage subsystems supporting up to two
redundant RAID controllers and one of the following host server connectivity options:
SAS on DS3200.
iSCSI on DS3300
FC on DS3400
Each DS3000 is a 2U rack mountable enclosure, containing one or two RAID controllers, two
power supply units and up to 12 SAS disk drives. The disk drives are installed at the front, as
shown in Figure 2-1.
For larger disk configurations, you can attach up to three EXP3000 SAS expansion
enclosures for a maximum of 48 disk drives. When using 300 GB SAS disk drives, the
maximum storage capacity exceeds 14 TB.

RAID controllers and power supply units are installed in the rear, as shown in Figure 2-2.

RAID controllers support RAID levels 0, 1, 3, 5 and 10. Each controller has 512 MB of cache
(upgradeable to 1 GB) and a cache battery. The battery can maintain the data in cache for up
to three days in the event of power outage.
In dual controller configurations, the left controller is A and the right is B, when seen from the
rear view of the subsystem.
Dual controller configurations offer redundant access to disk storage. In case of controller or
I/O path failure, the other controller will continue to provide access to disk drives.
DS3000 RAID controllers have connectors for the following ports:
Host server attachment ports (SAS, iSCSI or FC)
Drive side SAS ports
