back-end storage connections. Each I/O module contains four 8 Gb/s Fibre Channel ports.
• I/O module carrier, containing two Fibre Channel I/O modules (one for each director) for intersite and
intrasite communication. Each I/O module provides four Fibre Channel ports.
• CPU module.
• Two 30 GB solid state drives (SSDs), one for each director.
• Two management modules
• Two redundant power supplies
• Four fans
Standby power

Provides backup power (through a pair or redundant modules) that allows an engine to ride through transient
(30 seconds or less) power loss.
