Multipath Failover with 2 Switches

[michi616]

so, i have testing the other stacking port and that was more better. At the moment i think that a Switch have a problem with one of the stacking ports. Tomorow i become a another switch, so that i can make more tests.

But a another Question:

I have install Open-E VSS6 up90 and this have a better performance as the up95 version.

Iometer in a VM on up95:
I/Os / second = ca. 6000
Total MB / second = 96MB/s

Iometer in a VM on up90:
I/Os / second = ca. 8000
Total MB / second = 125MB/s

Why is there so a big difference?

Is as posible to optimate up95?

EDIT:
Is it normal, whan a switch go down (in multipath configuration) that i must wait 2 minutes for a normal work?

thanks.

Check your spanning tree configuration on your ports. Make sure you turn on portfast or if you are using RSTP, that you make your ports edge ports.
You can also adjust the iscsi client timeouts as well. This can improve the speed of recovery when you loose a link.
