Direct-management method:
This method uses Ethernet connections from a management station to each
controller. You must install at least one management station. The management
station can be the host or a workstation on the Ethernet network. A management
station will have the client software installed. Attach Ethernet cables to each
management station (one pair per storage server). You will connect the cables to
each controller later when you install the storage server. Figure 18 shows the direct
management method.

Storage subsystems
Fibre Channel connections
The storage server Fibre Channel consists of a host Fibre Channel loop and a drive
Fibre Channel loop. The host Fibre Channel loop provides the fibre path for host
attachment. It can consist of Fibre Channel cables, SFPs, host bus adapters, Fibre
Channel switches, and RAID controllers. The drive Fibre Channel loop provides the
fibre path to the hard disk drives (HDDs). The drive Fibre Channel loop consists of
Fibre Channel HDDs and optional drive expansion units, Fibre Channel cables, and
SFPs.
The FAStT600 Storage Server supports redundant disk-drive-loop configurations.
Each RAID controller has three SFP ports. These SFP ports are labeled

or more expansion units to the redundant RAID controllers. Then, use dual
