fibre channel vs iscsi

First, the basic architecture of Fibre Channel FC-4 Upper Layer Protocol:scsi,hippi,sbccs,802.2,atm,vi,ip FC-3 Common Service FC-2 Framing Protocol/flow Control FC-1 Encode/decode FC-0 media:optical or Copper,100mb/sec to 1.062gb/sec Describe: FC-0: Physical layer, customized to different media, transmission distance, signal mechanism standards, also defined fiber and copper interface and electrical

The Hyper-V virtual Fibre Channel feature for virtual machines enables virtual machines to access Fibre Channel-based storage devices. This feature enables enterprises to virtualize workloads that require Fibre Channel usage, and

Failure phenomenon: VNX the Fibre Channel interface configuration instructions on Mirrorview. Solution: The 1 Vnx block system supports up to 1 FC based MIRRORVIEW/S interfaces (one per SP). This FC port number is specified the first time a front-end FC port is configured, regardless of whether mirrorview/s is turned on or configured. The mirrorview/s port number in the Vnx product Rimmer is considered

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
