EMC CLARiiON CX300, CX500, CX500i, and CX700 Storage Systems Configuration Planning Guide
If your servers and storage systems will be far apart, you can place
the switches closer to the servers or storage systems, as convenient.
A switch is technically a repeater, not a node, in a Fibre Channel loop.
However, it is bound by the same cabling distance rules as a node.
EMC CX300, CX500, and CX700 disk-array storage systems, with
their storage processor (SPs), power supplies, and cooling hardware
form the storage component of a Fibre Channel system. The
controlling unit is a CX300 or CX500 disk processor enclosure (DPE2)
or a CX700 storage processor enclosure (SPE). A CX700 SPE, outside
of its cabinet, is shown in Figure 1-6.
CX700 Storage Processor Enclosure (SPE)
Each CX300 (DPE2), CX500 (DPE2), and CX700 (SPE) has two SPs.
The number of ports for each SP varies between storage systems.
Table 1-3 lists the number of ports per SP for each system.
