Hi Everyone,

Just seeing if anyone has deployed the Nexus 6000 switches. We deployed two Nexus 6001 as our main core in our data center and are really happy with them. We didn't have space for the Nexus 7000 and these worked out well. We are now upgrading our blade chassis to 10GB for more throughput.

Let me know if your using 6000 in your data center.

Nexus 6001 is a good switch, although I kinda wish that it supports 1G as well for connecting devices like router on a routed port. Did you run into any limitation using 6001 at the core? Which N2K do you have connected?

We bought some glc-t spf and used them to connect our Brodcade FCIP routers (ick, long story on fight with the SAN guys on converged networks) to our Nexus 6000's. Seems to work pretty well other then the price for a Cisco GLC-T spf.

Currently we are running Nexus 2248TP for our FEX. One gotcha that we all missed when designing is you can't hook another switch to a FEX. We currently have Cisco switches on our Blade chassis. There is a work around by disabling bpduguard.Not the best solution but those blade chassis will be going away.

I just looked and it seems 6001 does support 1G. I could have sworn it didn't when first came out.
Yes.. N2K is meant for end host only as BPDUGuard is enabled by default. You can disable BPDUGuard to connect a switch (although not recommended) as long as there is no redundant links otherwise, without STP, you might create a switching loop.
Also just saw 6001 also support PBR now, a feature that is still missing on N5K.

Also one the feature missing that I found out is there is no netflow currently. From what I have heard its on the road map but no ETA on when it will get released.

Hi Guys,

Thanks for the info regarding Nexus 6001. I was actually looking at a Cisco Nexus 5548 for a collapsed Aggregation/Core switch as I was planing to use FabricPath with some Nexus 5548 configured as access switches. The only problem I saw with the 5548 was the L3 throughput which is limited to 160 Gbps (240 Mpps). Then I saw the 6001 and the price difference is not so huge (around 10K $) including L3 licenses and FP. The 6001 has line rate L3 forwarding so I think, woww, that is quite impressive! And 1G support is great, was not supported before.

My concern is regarding the ports buffer capacity when comparing 5548 to 6001. Especially when going from 10G to 1G. Do you have any experience to share regarding that ?

Also, you are more than welcome to share your general experience with the 6001.

Regards,
Laurent

Laurent, I have looked at the pricing between N5K/6K especially with the 2K bundle and they come out very close like you said. 6K has most 5K features except the native FCoE support. Regarding the port buffer, could you share some detail as far as how much of a difference they are?
