Stack 5412 Chassis

Stack 5412 Chassis

Hi,

I have two 5412 chassis in a MDF and I would like to stack them. I believe there are a couple of ways or maybe more of doing this:

1. 10 Gig DAC cables - Is there an down-side of using this option. Would I ever get hit the bottle neck and/or peak out at 10 Gig? We currently have Cisco 3750 stacks and these stacks have I believe a through-put of 16/32 Gigs.

2. 40 Gig links - this is an option by using 40 gig links/VSF.

Thoughts,

P

Re: Stack 5412 Chassis

VSF is supported on Aruba 5400R zl2 Switch Series (latest 16.0x software branches) and its deployment require you to follow precise guidelines and respect listed restrictions.

Both 10G/40G physical interfaces can be used as (member of) VSF port...DAC included (which, I think, are better than SFP+ Transceivers plus fiber optic patch cables), not only SFP+ and 10GBase-T.

Look for 5400+VSF (or 5400+redudancy) related topics already discussed here on the HPE Community.

Re: Stack 5412 Chassis

Just to clarify - are you saying DAC cables would be better? Also - having DAC 10 Gig cables - would you ever hit the 10 Gig limit which connects both of the chassis? Is there any way to see throught-put on Cisco stack?

Thanks,

Re: Stack 5412 Chassis

Well, yes...DAC Cable IMHO is better than SFP+ Transceivers coupled through a fiber optic/copper cable (look for DAC cabled versus SFP+).

Regarding your second question consider that - if budget/planning permits - multiple, up to eight (better of different modules), physical interfaces can be aggregated together to form the VSF logical port (that way you're introducing resiliency on the VSF link and, concurrently, enhancing bandwidth between both VSF members).
