3.4.7 DS5000 storage subsystem host-side connections
The DS5000 storage subsystem integrates the host-side and drive-side connections into the
controller itself. DS4000 models use built-in host ports while DS5000 models use flexible Host
Interface Cards that can be replaced by IBM service personnel only. Each DS5000 controller
holds up to two Host Interface Cards (HICs) (see Figure 3-28).
These HICs are currently available:
򐂰 4 Gbps FC HIC (four ports per HIC)
򐂰 8 Gbps FC HIC (four ports per HIC)
򐂰
1 Gbps iSCSI HIC (two ports per HIC)

The HICs noted as (2) are shown in Figure 3-28. Thumb screws (3) support easy
replacement. Different faceplates (6) are used to describe the LED status of the host port
LEDs. The faceplates are described in Figure 3-22 on page 48, Figure 3-23 on page 48, and
Figure 3-24 on page 49.
