About CX300, CX500, CX500i, and CX700 Storage Systems In Figure 1-4, Server 1 has access to one SP in storage systems 1 and 2; it has no access to any other SP. Server 1 Server 2 Server 3 Adapter Adapter Adapter Zone Switch SP SP SP SP SP SP Storage System 1 Storage System 2 Storage System 3 EMC1806 Figure 1-4 A Switch Zone To illustrate switch zoning, Figure 1-4 shows just one HBA per server and one switch. Normally, such installations include multiple HBAs per server and two or more switches. If you do not define a zone in a switch, all adapter ports connected to the switch can communicate with all SP ports connected to the switch. However, access to an SP does not necessarily provide access to the SP's storage. Access to storage is governed by the Storage Groups you create (explained in Storage Groups on page 1-15. Fibre Channel switches are available with 8, 16, 32, or more ports. They are compact units that fit into a rackmount cabinet.
