IBM System Storage DS3000: Introduction and Implementation Guide
Figure 2-5 DS3200 RAID controller with three SAS host ports
The DS3200 single controller version does not provide redundant host attachment, therefore
we recommend to use the dual controller setup whenever possible.
2.1.2 IBM System Storage DS3300
The DS3300 offers iSCSI host servers connectivity for System x and BladeCenter servers.
Each controller has two 1Gbps iSCSI host ports (shown in Figure 2-6) that can be used for
host server attachment. You would normally use Ethernet switches between the host servers
and DS3300 controller iSCSI ports in order to establish Ethernet-based SAN. Up to 32 hosts
and 16 maximum host types can be attached.

2.1.3 IBM System Storage DS3400
The DS3400 can have one or two RAID controllers. Each controller has two 4 Gbps capable
FC ports for host server attachment. You need to install an SFP module in each FC
connector. The FC ports can operate at 2 or 4 Gbps, depending on the SFP module installed.
You can attach up to two host servers directly, but a SAN switch infrastructure is required for
more than two servers.
Figure 2-7 shows the DS3400 RAID controller. The arrows point to two FC host ports.

As with the DS3200 and DS3300, we recommend using the dual RAID controller
configuration. This will provide redundant disk storage access to the host servers.
2.1.4 IBM System Storage EXP3000
The EXP3000 is a 2U rack-mountable SAS disk drive enclosure. It supports up to 12 SAS
3.5” disk drives. If you use 300 GB disk drives, the maximum storage capacity in a single
