Datasheet

The SAN32M-2 Express Model was
designed specifically for use as the
SAN switch in this type of configuration.
It is easy to install and easy to manage.
The tan, green and blue servers repre-
sent heterogeneous server types which
are members of the same SAN and
share capacity of the large disk system.
The SAN32M-2 Express Model can be
upgraded to 32 ports and is future-
ready to support 4 Gbps servers and
storage devices as they are introduced.
Its flexible design allows participation
with other SAN m-type switches in fab-
rics that evolve as requirements
change. And it supports advanced
functions to enable participation in
complex fabrics including cascaded
switches and ISL trunks.
High availability SAN configuration
Many applications require continuous
operation. A common design approach
to achieve that objective is to run multi-
ple instances of the application across
a cluster of servers. When a server fails
or must be taken offline for mainte-
nance a backup server is available to
continue operation with a minimum of
impact. Redundant paths to data are
usually configured in a clustered server
environment for the same reasons in an
effort to provide continuous access to
data. Each server is configured with
redundant Host Bus Adapters. And
each Host Bus Adapter is connected to
a different SAN switch, and each switch
is connected to a different controller in
a disk system. Every effort is made to
provide continuous application access
to data.
The SAN32M-2 Express Model is an
excellent switch to use in a clustered
server environment. Separate SAN
switches enable two separate SAN fab-
rics, which are desirable as a means to
minimize or eliminate single points of
failure. The tan cluster shown above
provides redundant components at
every level and is designed to minimize
application outages.
Business continuity solution
Many small and medium size compa-
nies want to implement a business con-
tinuity or remote backup capability to
meet strict new regulatory require-
ments. The SAN32M-2 Express Model
can provide the SAN connectivity
required for these environments. The
diagram on the following page is
intended to represent two different
sites. The blue side represents the pro-
duction site and the green side repre-
sents the remote or backup site.
