Verifying the Emulex HBA driver settings on FC systems
Controller 1 owns the disks where the LUN for Server 1 is currently located. This process can be initiated from the local host or remote hosts. Server 1 is allowed to connect over both Fabric A and Fabric B. I do the same on my storage system which has also got redundant HBA ports.
Configure Emulex HBA to Boot from SAN
Servers' access to their storage will invariably be mission critical for the enterprise, so we're not going to want to have any single points of failure.
I work in education and we are currently having issues with our SAN cluster. TPGs can be used to control which ports initiators can access the storage target on. The Brocade and HBAs are available through retail channels only.
In our opinion, the current Emulex HBA product family is mature, robust, and well suited for large to small enterprise Fibre Channel deployments. Want the complete course? Each product takes a different approach to many of the day-to-day HBA administrative tasks. This allows for failover in the event of a failure along one path and can provide for load balancing across multiple paths.
Brocade ESCM can be installed on a host that does not have Brocade HBAs installed, and it can manage remote hosts by adding the remote hosts as described previously.
Fibre Channel SAN Part 3 – Redundancy and Multipathing
HBAs are a part of the complete multipathing solution and are typically certified to work with various multipathing solutions from operating system vendors, file system vendors, storage vendors and others. Multipathing is deployed in many Multiapth Channel storage environments in order to provide more than one path between the server multipathh the storage.
Viewed times Community Rating: ESCM has a function to add remote hosts to its internal discovery list. The dual-port tests were run with the Emulex and Brocade dual-port cards with both ports active. I also need to configure my Fabric B switches. The current Emulex HBA product family is qualified and supported by all the major server, operating system and storage vendors. A series of IOMeter tests were run spanning a wide range of block sizes for reads and writes.
This would be disastrous. In this video I cover the redundancy options available for Fibre Channel, and how clients multpiath choose the paths to their storage through multipathing.
Emulex has a proven HBA customer support center with a great deal of expertise and history. Emulex and Brocade have apparently taken two somewhat different philosophies for the installation of HBA drivers and HBA management software.
Emulex HBAs have been qualified, sold and supported mkltipath every major server and storage vendor. A single click can switch between Host View and Fabric View as shown below. Nultipath addition to the form factor required for tower and rack servers, blade servers often have their own special form factor, requiring a somewhat specialized HBA.

The two fabrics are kept strictly physically separate from each other which is signified that the big red line up the middle of the diagram.

See the full May article at Demartek. Switches are dedicated to either Fabric A or Fabric B.
The first port is connected to Fabric A and the second multipayh is connected to Fabric B. Mhltipath is critical in large environments where server reboots are not tolerated in certain circumstances.
In Ethernet, if you want to connect a client to a server, you have to point the client at the server's IP address. I configure that on one of the two Fabric B switches, and it will propagate it to the other Fabric B switch.
