High intelligence, high availability, and high reliability are the characteristics of multi-layer intelligent optical fiber switch. Although its technology is not very mature yet, it has been recognized by people. Cisco Systems recently announced that it will launch the CiscoMDS9100 series of multi-layer smart Optical Fiber switches this fall to meet the needs of

If the company decides to deploy an optical fiber channel storage area network (SAN), then it should determine the supplier of the switch, because it is unwise to mix different brands. Fiber Channel switches need to communicate and cooperate with each other to manage the entire network. To ensure that the switches comm

In addition to FCIP, another method is iSCSI, which converts user requests into SCSI code and encapsulates data into the IP package for transmission over Ethernet. To connect a geographically dispersed SAN, the FCIP Protocol can only be used for Fiber Channel Technology connections. In contrast, iSCSI can run on an existing Ethernet. SAN connections, such as FCIP and iSCSI protocols, can provide higher perf

, the traffic originally assumed by the port will be allocated to other normal ports through the traffic distribution algorithm again. The traffic distribution algorithm is determined by the switch hardware.To make the port channel work normally, the member ports of the port channel must have the following attributes: All ports are in full duplex mode; The port speed is the same; The port type must be t
