Your SAN environment must meet certain requirements to support the use of the
system.
Before you begin
To install a
system into an existing SAN that is in use during installation, you must first ensure that the
switch zoning is set to isolate the new system
connections from the active
part of the SAN.

Procedure
- Consider the design of the SAN according to your requirement
for high availability.
-
Identify the operating system for each host system that will be connected to the
system. Ensure
compatibility and suitability by completing the following steps:
-
Specify the host bus adapters (HBAs) for each host.
-
Define the performance requirements.
-
Determine the total storage capacity.
-
Determine the storage capacity per host.
-
Determine the host LUN sizes.
-
Determine the total number of ports and bandwidth that are needed between the host and the
system.
-
Determine whether your SAN has enough ports to connect all hosts and back-end storage.
-
Ensure that the existing SAN components meet the requirements for the system
by completing the following
steps:
-
Determine the host system versions.
-
Ensure that the HBAs, switches, and controllers are at or above the minimum requirements.
-
Identify any components that must be upgraded.
