Most of the procedure for installing a SPOFless cluster is

Another factor concerning the installation of FC Array

is advisable to install a copy of the client on each cluster

during periods of network instability.
RS/12FC External Shared Storage Configuration
The FC Array Assistant utility is used to configure, manage

mode is recommended because it provides more control

to download the firmware individually to each controller.

Also, when flashing the firmware on the controller, the
