What is Plogi and Flogi?

Fabric Login (FLOGI): This is performed between an N-port and an F-port. Port Login (PLOGI): This is performed between an N_port and another N_port in order to establish a session. With this login, there is a simple exchange of PLOGI and ACC frames between the nodes.

What does Flogi stand for?

Fabric Login
Fabric Login (FLOGI) When you connect your server or storage, it will send a Fabric login (FLOGI) request. This FLOGI request serves two purposes: Fibre Channel ID is the WWPN connection to this port from the FLOGI server. Exchange buffer credits with the switch.

What is Fcid storage?

The FCID is similar to an IP address in Ethernet. It’s used by Fibre Channel switches to route traffic between servers and their storage. Switches maintain a table of FCID to WWPN address mappings and what port the host is located on. The Fibre Channel switches share information with each other.

What is Plogi SAP HR?

PLOGI is a standard Organizational Management Transparent Table in SAP Basis application, which stores Table Index HRP* data. You can use the transaction code SE16 to view the data in this table, and SE11 TCode for the table structure and definition.

What is hard zoning and soft zoning?

Hard zoning is zoning which is implemented in hardware switches. In comparison, soft zoning uses World Wide Names (WWNs) to set up the zone, and device assignments can be changed to respond to the varying demands of servers in a network.

How does FC work?

How FC Works on the Switch. The switch connects devices that support FC and Ethernet (such as FCoE servers on an Ethernet network) to an FC SAN, thus converging the Ethernet and FC networks on a single physical network infrastructure.

What is Wwpn storage?

In computing, a World Wide Port Name, WWPN, or WWpN, is a World Wide Name assigned to a port in a Fibre Channel fabric. Used on storage area networks, it performs a function equivalent to the MAC address in Ethernet protocol, as it is supposed to be a unique identifier in the network.

Where is soft zoning preferred over hard zoning?

i) Soft zoning is also WWN zoning and it is preferred when user need flexibility to physically move attached nodes between switch prt cable the SAN, that may take place during switch maintenance and repair without reconfiguring the zone information. This is possible because the WWN is static to the node part.

How many devices can be connected in FC?

127 FC devices
An FC-AL natively uses the SCSI-3 (SCSI FCP) protocols and can address 127 FC devices or nodes within the limitations of the 30-meter copper cable or the 10km optic cable. (A SCSI connection can handle only seven devices, excluding the computer.) FC-AL is a simple closed serial loop.
