About CX300, CX500, CX500i, and CX700 Storage Systems
Fibre Channel Storage Components
A Fibre Channel storage system has three main components:
◆
Server component (host bus adapter driver with adapter and
software)
◆
Interconnect components (cables based on Fibre Channel
standards, and switches)
◆
Storage component (storage system with storage processors,
power supply, cooling hardware, and disks)
Server Component (Host Bus Adapter and Driver)
The host bus adapter is a printed-circuit board that slides into an I/O
slot in the server’s cabinet. It transfers data between server memory
and one or more disk-array storage systems over Fibre Channel — as
controlled by the support software (adapter driver).
Interconnect Components
The interconnect components include the optical cables between
components and any Fibre Channel switches.
The maximum length of optical cable between a CX300, CX500, and
CX700 storage system and a server or switch ranges from 150 to 500
meters (165 to 550 yards), depending on the type of cable and
operating speed. With extenders, connections between servers,
switches, and other devices can span up to 60 kilometers (36 miles) or
more. This ability to span great distances ia a major advantage of
optical cable.
Details on cable lengths and rules appear later, in Chapter 6.
Fibre Channel Switches
A Fibre Channel switch, which is required for switched shared
storage (a storage area network, SAN), connects all the nodes cabled
to it using a fabric topology. A switch adds serviceability and
scalability to any installation; it allows online insertion and removal
of any device on the fabric and maintains integrity if any connected
