Host, Network, and Drive Tray Ports and LEDs

The controllers are equipped with specific interfaces for connecting, powering,
configuring, and managing the storage system. The component LEDs display the
operating status of the storage system.

Front-end modules

The front-end modules (FEMs), also called channel boards (CHBs), control the transfer of
data between the host and cache memory. VSP G130, G/F350, G/F370, G/F700, G/F900
storage systems support Fibre Channel (FC) and iSCSI FEMs for attachment to host
servers. The front-end module LEDs indicate the operating status of the module.
