EMC Fibre Channel Storage-System Configuration Planning
About Fibre Channel Storage Systems and Networks (SANs)
Fibre Channel Storage Components
A Fibre Channel storage system has three main components:
• Server component (host-bus adapter driver package with adapter
and software)
• Interconnect components (cables based on Fibre Channel
standards, switches, and hubs)
• Storage components (storage system with storage processors —
SPs — and power supply and cooling hardware)
Server Component (Host-Bus Adapter Driver Package with Software)
The host-bus adapter driver package includes a host-bus adapter and
support software. The 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).
One or more servers can use a storage system. For high availability —
in event of an adapter failure — a server can have two adapters.
Depending on your server type, you may have a choice of adapters.
The adapter is designed for a specific host bus; for example, a PCI bus
or SBUS. Some adapter types support copper or optical cabling; some
support copper cabling only.
Interconnect Components
The interconnect components include the cables, Fibre Channel
switch (for shared storage), and Fibre Channel hub (for unshared
storage).
Cables Depending on your needs, you can choose copper or optical cables.
