Switch Options

Not sure if I'm in the right place but I'm looking for some switch advice. I'm currently looking for a switch for our MSA/VMware storage network. We're switching from 1G Copper to 10G Fibre iSCSI traffic. My current thought is a pair of 5406R ZL2 using a J9993A fibre module. The switch gives me some possibility for future expansion and I'm thinking I can use it to handle the main access and vmotion networks as well?

This is just my thought I'd be interested in what others think of utilizing this setup or what other switches would be recommended?

Thanks

Re: Switch Options

Do you mean deploying the pair Aruba 5400R zl2 as a VSF or just using two standalone Switches?

I saw some Validated Reference Designs (one is here) using two Aruba 8320 (I think not deployed as a VSX...which is somewhat strange IMHO) along with two Aruba 3810M for management...it could be overkill (especially using Aruba 3810M just for management and not using VSX on ToR Aruba 8320). Another interesting guide is this one. you will notice how ethernet portions (the isolated ethernet network - for iSCSI over 10Gbps interfaces - placed between VMware Hosts and HPE MSA and ethernet network - for frontend connectivity - placed between VMware hosts and its clients) are implemented without indicating a particular switch series (nor brand)...the focus was on the Fibre Channel side on that guide. You can use also HPE FlexNetwork (with deep buffers for iSCSI!) switch on the VMware Hosts <--> MSA portion...of any other deep buffer switch series...I'm not totally sure that positioning there two modular Aruba 5400R zl2 will be wise...better two Aruba 3810M (if Aruba 8320s are out-of-budget). The frontend net could instead a good place for Aruba 5400R zl2...but you should also consider new series like Aruba 6300F/6300M and 6400M recently presented.

Re: Switch Options

Sorry for the delay getting back to you; I've been away over the Holiday period. Thanks for the excellent advice; keeping the iSCSI traffic isolated does sound like the best course of action. The 2x Aruba 8320 (JL479A) seems like the best option if I can get the budget signed off else the 3810M seems to be a good backup option.

Thanks again.
