1 Introduction to the FCSA
This section provides an introduction to the Fibre Channel ServerNet adapter (FCSA)
for I/O Adapter Module (IOAM) enclosures.
Overview of the FCSA
The M8840 FCSA provides fibre-channel connectivity between:
•
A NonStop S-Series system and an Enterprise Storage System (ESS)
•
An Integrity NonStop S-Series system and a disk drive enclosure containing M8xxx
fibre channel disks.
•
An Integrity NonStop NS-Series system and a disk drive enclosure containing
M8xxx fibre channel disks.
•
An Integrity NonStop NS-series system and an ESS
•
An Integrity NonStop NS-series system and a M8201 Fibre Channel to SSCI
router, a device that allows connection to N1525A tape drives.
When you connect a NonStop system to an ESS, the FCSA, allows you to connect
either directly (direct connect) or through a storage area network (SAN) (switched
connect). (In this manual SAN refers to a storage area network and ServerNet SAN
refers to a ServerNet system area network.)
The FCSA has two ports that allow connection to external, fibre-channel-enabled
devices. Figure 1-1 shows the ports on the FCSA.

Note. In this manual, the term port refers to the physical connector on the adapter to which
the cable is connected and is used for hardware discussions such as adapter location and
connectors. The term ServerNet addressable controller (SAC) refers to the software
presentation of the port (the I/O controller) and is used when discussing configuration.
Caution. Do not use the Ethernet ports on the FCSA. The Ethernet ports are not compatible
with the FCSA fibre-channel ports. Port 1 and Port 2 in
Figure 1-1 are available on an FCSA.
