Datasheet

Switch investment protection
SAN b-type switches and directors use
common firmware—from the sixteen-
port switch to the 256-port director—
which helps simplify SAN fabric
expansion. Common firmware supports
forward and backward interoperability
of the SAN16B-2 Express Model switch
and helps simplify deployment with
existing SAN infrastructures. ISL trunk-
ing can interoperate with existing
2 Gbps switches. Since the SAN16B-2
Express Model switch can operate at
up to 4 Gbps, it is ready to operate
with future 4 Gbps capable server
adapters and storage devices when
they become available.
Multiple management options
In addition to Web Tools EZ, the
SAN16B-2 Express Model fabric switch
provides advanced options to help
manage the SAN. Switch fabric man-
agement is available through various
interfaces including GUI, SNMP, Telnet
and serial port. Remote access and
remote management is also available.
Advanced Zoning
Advanced Zoning provides hardware-
enforced zoning that helps protect
against unauthorized or unauthenti-
cated storage network access, non-
secure management access and World
Wide Name (WWN) spoofing.
Optional features
B16 4-Port Express Model
Activation
Enables upgrade from 8 to 12 to
16 ports. The base model activates the
first eight ports (0 to 7). The first 4-Port
Activation feature activates ports eight
to eleven (first four-port increment) and
the second 4-Port Activation feature
activates ports twelve to fifteen (second
four-port increment).
B16 Full Fabric Activation
The switch by default can connect to
servers and storage. Full Fabric
Activation is required to enable E-Ports
capability to allow connection to other
switches via Inter-Switch Links (ISLs).
Full Fabric Activation is a prerequisite
to Advanced Security Activation,
Performance Bundle Activation and
Performance Monitoring.
B16 Extended Fabric Activation
Extended Fabric Activation enables the
Extended Fabric capability within the
SAN16B-2 Express Model firmware.
Extended Fabric is designed to provide
extensions within switch internal buffers
to maintain performance over distances
between ten and eighty kilometers by
maximizing data buffering on switch
interconnect links (ISLs).
B16 Fabric Watch
Fabric Watch is designed to enable
real-time proactive awareness of the
health, performance and security of
each switch and automatically alert net-
work managers of problems in order to
avoid failures.
B16 Advanced Security Activation
Advanced Security Activation is
designed to enable policy-based secu-
rity mechanisms integrated with Fabric
Operating System. All switches and
directors within the SAN fabric must be
configured with their respective
Advanced Security Activation feature.
B16 Performance Monitoring
Activation
Performance Monitoring Activation
helps to identify end-to-end bandwidth
usage by host/target pairs and is
designed to provide information for
capacity planning.
B16 Enhanced Trunking Activation
Enhanced ISL Trunking is supported
between a SAN16B-2 Express Model, a
SAN16B-2, a SAN32B-2 Express
Model, a SAN32B-2, a SAN64B-2 or a
SAN256B and enables Fibre Channel
(FC) Packets to be distributed across
up to four 4 Gbps capable ISLs for a
combined bandwidth of up to 16 Gbps.
ISL trunking eliminates rerouting and
possible application downtime arising
from link failure.
