Need your advice guys,
We have a design with cisco UCS B series dual Fabric interconnect and dual MDS san switch with one storage VNX5500.
I am actually doing the zoning but i need to determine what is the best practice cabling and zoning. and i don't have powerpath installed in the vmware side:
1st Design :
The zoning will be
Is there a best practice ? what is the advantage of 1st or 2nd design, what is the best for performance or redundancy ?
A second question is does Vhba1 and Vhba2 will work simultaneously ? if yes what about round robin, is it just about fc path ?
My choice actually is the first one because if we loose mds1 we still have a path from Vhba2 via md2 to SPB so LUN can stay on SPB and no risk for LUN trespass or huge use of BUS cmi between SP. Please confirm if i am right
you are correct, definitely option 1. VMware native MPIO will do a pretty good job of load-balancing I/O so by having SPA and SPB ports on each fabric you will engage both HBAs in round-robin fashion. UCS FIs in host-end mode ?
