A comment by Brook Reams on my recent blog post was a fantastic surprise: Brocade is the first vendor that actually shipped a VXLAN VTEP controlled by a VMware NSX controller. It’s amazing to see how Brocade leapfrogged everyone else (they also added tons of other new functionality in NOS releases 4.0 and 4.1).
2014-04-23T06:33Z: updated the blog post to mention Arista's IP MC VTEP and Nuage VSG 7850
The really interesting part
Every other shipping hardware VXLAN gateway (Arista and F5) that integrates with vSphere environment implements multicast-based VXLAN.
Brocade decided to skip the multicast VXLAN support and implemented only VMware NSX gateway functionality. Obviously they don’t believe in viability of Cisco’s Nexus 1000V (or VMware’s vCNS).
- Arista has a shipping L2 VTEP that uses IP multicast. They might have OVSDB agent (which is needed to work with the NSX controller), but it’s not yet documented in public EOS documentation.
- Nuage VSG 7850 is also shipping, but does not work with either multicast-based VXLAN or NSX controller. It uses MP-BGP to integrate with other controllers within the Nuage's Virtual Services Platform (VSP).
- Cisco is going its own way with ACI.
- Dell seems stuck – the Z9000 documentation published on their web is almost a year old, everything else is older.
- HP claims hardware VXLAN support on FlexFabric 5930AF switches (which probably means “we’re using Trident-2 chipset”); haven’t found anything VXLAN-related in their manuals.
- Juniper is promising VXLAN on QFX5100 and MX-series routers; it looks like they haven’t shipped yet.
The Data Center Fabrics update session in May 2014 will cover new data center switches and software functionality introduced by Arista, Brocade, Cisco, Juniper, and maybe one or two other vendors in the last 12 months.
Do I have to mention that you get immediate access to all existing materials and videos of the Data Center Fabrics webinar when you register for the update session?
