I can set the MTU of Best Effort however my understanding is Fibre Channel traffic within the UCS will use the Fibre Channel system class.įurthermore I noticed I can set the Maximum Data Field Size on the vHBA's within the UCS manager however my understanding is the maximum this can go up to is 2048.The CVD program consists of systems and solutions designed, tested, and documented to facilitate faster, more reliable, and more predictable customer deployments. However in the UCS manager when I go to QoS System Class, the option to set the MTU for Fibre Channel is greyed out and it doesnt look like there's anyway to override the preset frame size. For example on the NetApp gear I can set the MTU per interface, on the Cisco MDS I can set the MTU per vsan. I've read these two articles which provide some excellent information on implementing Jumbo Frames and Fibre Channel Jumbo Frames:Įverything within the SAN I'm administrating has the ability to set the MTU up to 9036 except for the UCS. I was wondering if it's actually possible to have Jumbo Fibre Channel Frames running on a UCS?
