Fibre Channel Trunking (Aggregation): Better Performance, Higher Bandwidth (>1 Tb/s)

We are all knowing LACP on ethernet network but Fibre Channel and SAN network providing multipathing I/O by using logical and physical paths as single device on operating system and also using path selecting policies for using I/O paths optimized. But if server using 16Gb/s FC HBA, so there is no bandwidth aggregation. Server can generate bandwidth for each port up to maximum speed of port and also path selecting has performance impact of server when large paths are presented to server. Months before, I was thinking about FC port aggregation and did many searches but I didn’t find anything until now.

We had 6th generation of blade servers and the first virtual desktop infrastructure farm hosted by the servers in Iran and even Middle East. Now I didn’t find any official information about HPE Blade System retirement but after BL6xx server are retired and BL4xx servers released by some limitation compare to Synergy servers, it was clear.
