Network Resiliency 2 x 5400zl

[KeithHubner]

Hi,

I have 2 x HP Procurve 5400zl 's with the premium license. I am interested to know recommendations on how to use these for best resiliancy? I have two buildings and was thinking of using VRRP to allow routing failover.

My concern is whether this will lose performace as I am currently using an HP P4500G2 iSCSI SAN with 2x1Gbps NICs. Would dual homing, one in each switch, mean that I would only get 1Gbps throughput on the SAN?

Thanks,

Keith

BUMP Anyone? Please???

Hi,

When you say you have two buildings do you mean you have one 5400 in each and how are they connected at present? Also how is your SAN switch currently connected to your switch(es)?

To give you an answer in generic terms VRRP can be quite useful but you have to ensure your switches that are connected to your 5400s have a route to both otherwise there's not much point in running it.

With regards to connecting the SAN switch to both you could do this using distributed trunking on the two 5400s which should give you some level of load-balancing (i.e.. not restrict you to just one active 1Gb interface) but there are a few caveats for setting up DT so I'd recommend reading through the port trunking pages in the manual (chapter 11 under the management & configuration guide).
