ServerNet Adapters
Types of ServerNet Adapters
The following ServerNet adapters are currently supported on the NonStop S-series
server:
Table 2-1. HP ServerNet Adapters (page 1 of 2)
Adapter Description
ATM 3 ServerNet
adapter (ATM3SA)
Provides connectivity between NonStop S-series servers
and asynchronous transfer mode (ATM) networks. It
features one port per board. The ATM3SA uses the ATM
subsystem to deliver ATM connectivity. ATM is a
networking technology that relays fixed-sized cells as
opposed to frames or packets. This cell-relay model
reduces processing time in the switching hardware,
making ATM a high-bandwidth networking option.
Ethernet 4 ServerNet
adapter (E4SA)
Provides connectivity between NonStop S-series servers
and Ethernet 802.3 LANs. It features 4 ports per board,
with each port supporting communications speeds of 10
megabits per second (Mbps). The E4SA uses the SLSA
subsystem to deliver external LAN access. The SLSA
subsystem is described in ServerNet LAN Systems
Access (SLSA) Subsystem on page 2-11.
Fast Ethernet ServerNet
adapter (FESA)
Provides connectivity between NonStop S-series servers
and Fast Ethernet 802.3u LANs. It features a single-port
adapter supporting communication speeds of 100 Mbps
and 10 Mbps. The FESA uses the SLSA subsystem to
deliver external LAN access. The SLSA subsystem is
described in ServerNet LAN Systems Access (SLSA)
Subsystem on page 2-11.
Gigabit Ethernet
ServerNet adapter
(GESA)
Provides Gigabit connectivity between NonStop S-series
systems and Ethernet LANs. Two versions of the GESA
are available based on the transmission medium: copper
or fiber. GESA also provides an open interface for an
Asynchronous Wide Area Network (AWAN) and
ServerNet Wide Area Network (SWAN) attachment to a
ServerNet interconnect.
GESA is supported by SNMP and WAN Wizard Pro.
The data transfer rate for SWAN is 10 Mbps and 10/100
Mbps for SWAN 2. (This feature applies to GESA-C
only.)
