switch or a small fabric to manage,
EFCM Basic capabilities and functional-
ity can help simplify management of
your SAN solution.
Pay-as-you-grow scalability
The FlexPort Expansion feature is
designed to support scalable switch
upgrades. The FlexPort feature provides
an activation key and eight shortwave
SFPs which upgrades the switch in
eight-port increments while helping
avoid fabric disruption. The ability to
increase switch capacity while maintain-
ing service helps customers implement
a pay-as-you-grow strategy while mini-
mizing impact to applications.
High performance
The SAN32M-2 Express Model pro-
vides 4 Gbps performance on all ports.
Each port auto-negotiates to 4, 2 Gbps
or 1 Gbps, full duplex depending on the
capabilities of the attached device or
switch. Up to 256 Gbps aggregate
throughput is possible with 32-port
configurations.
Network performance can be enhanced
with Open Trunking feature which
automatically balances performance
throughout a network while minimizing
storage administrators’ involvement.
Open Trunking is designed to optimize
the total throughput between two
switches automatically by redirecting
traffic from high-utilization links to links
with available bandwidth. Open
Trunking is designed to continuously
monitor loads on all links, detect con-
gestion and automatically balance traffic
across available ISLs without operator
interaction. Based on constant traffic
monitoring, Open Trunking acts to help
improve throughput and reroute traffic
efficiently.
High-availability
Medium-size and enterprise businesses
require high-availability switch fabric
solutions. The SAN32M-2 Express
Model uses advanced application-
specific integrated circuits (ASICs) to
help minimize the number of internal
components and thus improve reliability.
The SAN32M-2 Express Model is
designed to provide hot-swappable,
load-sharing dual power supplies
designed to allow the switch to remain
online if one power supply fails. Dual
power cords allow attachment to sepa-
rate power sources to help improve
availability. Hot-swappable power sup-
plies with integrated cooling compo-
nents help eliminate downtime for
service when replacing a failed compo-
nent and help reduce or eliminate the
risk of erroneously cabling a replace-
ment switch because of a simple com-
ponent failure. Failed power supplies
require IBM service or switch replace-
ment and hot-pluggable optical trans-
ceivers can be replaced without taking
the switch offline.
FlexPort technology is designed to sup-
port switch port upgrades without fab-
ric disruption. In addition, HotCAT
online code activation is designed to
allow firmware to be downloaded and
activated while the fabric switch
remains operational. Redundant
switches can be deployed for high-
availability clustering applications.
Advanced solution management
Open System Management Server
(OSMS), a standard feature, is an ANSI
(American National Standards Institute)-
based capability that supports SAN
management software from vendors
such as VERITAS™, Tivoli and BMC.
OSMS is designed to extend the
switch’s capability to include in-band
management with an open systems
host-based application. OSMS allows
the fabric switch and devices attached
to it to be “discovered,” or seen in a
fabric through a framework software
application.
