ISCSI Switching - Transmitted Paused Frames
I'm no ISCSI expert having mainly worked with Fiber Channel.
Today I'm looking through some performance issues with a Dot Hill San and VM's hanging for a couple of seconds every now and then. One of the things I have noticed is there is some Transmitted Pause Frames on the ISCSI Switching (dedicated HP 1810-24G - Jumbo Frames Enabled).
Its not a huge amounts of packets considering the numbers of transmitted but I'm not sure if its a factor?
Ports 1-4 are trunked to a seperate switch which is seeing pretty similar numbers
Are these switches struggling to process the traffic?
