Re: Flex 10 transfer speeds
Some really pedantic questions, but the topology goes 10G from the chassis to the 5400, and 8x1G links directly from the same 5400 to the equallogic device right? And there is not even the physical possibility that some other uplink besides the port with the CX4 running at 10G is in use to the 5400?

Re: Flex 10 transfer speeds
I have tested both a bare iron computer running windows and a Blade with ESX running windows and both gave about the same results.

Re: Flex 10 transfer speeds
Do the port stats on the 5400 for its CX4 port show traffic when you are running the tests?

Re: Flex 10 transfer speeds
Yes the CX4 ports show traffic on the ports when doing the tests.

Re: Flex 10 transfer speeds
Other pseudo-random questions - what are the specific IP and MAC addresses involved? I don't know the details of the packet scheduling algorithm(s) in the 5400 but someone else watching might and knowing the addressing involved would be helpful.

Re: Flex 10 transfer speeds
http://cdn.procurve.com/training/Manuals/3500-5400-6200-6600-8200-MCG-Sept09-12-PortTrunk.pdf
talks about the traffic distribution algorithm for trunks on the Procurve 5400.
basically, for IP traffic it uses the last 5 bits of the source and destination IP address to determine which link to use.

Re: Flex 10 transfer speeds
When I run testes on the storage I see traffic on all of them.

Re: Flex 10 transfer speeds
gbic slots 1 and 4 share a 14.4gb channel and 2 and 3 share another, so in practice your 10gbe connections in slots 1 and 4 are only 7.2gb a piece at max, if you want the full 10gbe uplink you either have to leave slot 4 empty.
