Hello everybody,
this is my first post, so sorry if this is the wrong place.
a customer will receive two Nimble Storage Systems that will run a sync between them.
To realize this, we will use 2x Aruba CX 8320 in a stack, in each datacenter that are connected to each other with 4 (or more) 10gbe. They should also have a uplink to the existing coreswitches (Aruba 5400R zl2), which are also connected to each other.
Now the idea was to only Tag the required VLAN for the Nimble sync on the interconnect between the two CX 8320 stacks, which should avoid a loop and with that the blocking of that interconnect via STP.
But i am not sure if that actually works.
Coreswitch1 <> Coreswitch2 (trk1 every vlan except 999)
Switchstack1 <> Switchstack2 (trk4 only vlan 999)
Switchstack1 <> Coreswitch1 ((trk2 every vlan except 999)
Switchstack2 <> Coreswitch2 ((trk2 every vlan except 999)
The end goal is to have every link active to reduce latency for the Nimble Sync and avoid bottlenecks for the server traffic.
Thank you for the help.
