Wishful Thinking: The Nexus 1000V Edition
So, here we are again with another”Wishful Thinking” post because, yet again, someone would rather hurry to TGI Fridays for their appletini fix, than take the time to do some due diligence. Or, perhaps they can’t come up with anything useful to say about their own products and decided to make stuff up about ours.Anyway, lets tackle some of the rumors, whispers and innuendo our customers are hearing around the Cisco Nexus 1000V. The most popular assertion seems to be something along the lines of:
- The 1000V only works with Nexus switches, so you have to upgrade your network
- The 1000V requires you to use that new-fangled FCoE
- The 1000V requires you to replace your server’s network adaptors
- The 1000V can only be configured while wearing special slippers (OK, I made this one up, but its about as valid as the other things I have heard)
So let’s be clear: if your infrastructure can run ESX+vSwitch, it can run ESX+1000V without changes. The switch will run over GbE or 10GbE. The switch will run with your existing network interface (assuming it is on the ESX HCL–and if its not, you have larger problems). The Nexus 1000V will happily work with whatever upstream switch you have in place now–Catalyst, Nexus, whatever. Finally, the Nexus 1000V does not require FCoE, and, of course, your choice of footwear is your own. I’d say the Nexus 1000V is one of the most agnostic products we have every shipped.In fact, I’ll take this a step further on the issue of openness and compatibility. The Nexus 1000V will concurrently work across multiple server vendors and multiple form factors (blade, rack, multi-RU), which is something that not everyone can say. In short, if your infrastructure supports the next version of VMware ESX, it will support the Nexus 1000V.The second assertion is that there really isn’t any problem for the Nexus 1000V to solve, which is kinda funny, since we created the switch in partnership with VMware. In reality, I think anyone that has any kind of sizable VM deployment or has aspirations for a sizable deployment sees the immediate need for the Nexus 1000V both in terms of the VN-Link features it offers (VM-level config and troubleshooting, policy portability, etc) as well the streamlining of operations and coordination between server and network teams…or at least that has been my consistent experience talking to dozens of customers over the last year or so. I’d love to be able to wrap with some firm details on availability, pricing, etc, but, alas, we are not quite there yet. We are chugging along through the beta and we are currently on target to hit our goal of first half of this year.Stay tuned for details.
