Switch configuration best pratices with 4x E2910al

[Ralf Gerresheim]

Hi,

I'm planning a highly redundant P4000 System: 2 Datacenters, in each 2 E2910al LAN-switches and 2 P4500 Multi-site nodes.

How should I interconnect the 4 switches? Each switch with all other 3 switches? Or one switch in one datacenter to a switch in the other datacenter? And how to connect then the storage nodes?

Thanks in advance.

If you are going to have two 2910-AL's in each DC then you can connect them together with a static LACP trunk using either multiple 1000Mbps ports or alternatively you could install a CX4 10G module and connect them together with a pair of CX4 cables at 10Gbps (still using an LACP trunk).
