Probably works at a big hosting provider or colo or something, like me, though as far as I've heard we only have a handful of 5508-Xs in use; we mostly pushed people to the 5515-X as our entry level. Whatever the case, godspeed, 5508 guy. Godspeed.

Home depot has a gigantic wifi deployment, maybe that's it.

edit: scratch that wifi talk, thought he was referring to the WLC for some reason

Also there's a rumor that the 6800 will have an early EOL and nexus will become a datacenter and campus switch. Sucks to those who bought in.

Heard the same from a rep in the federal space a few months ago. Told us that 6500 and 6800 was getting abandoned sooner rather than later.

To be honest if you are a mid-level network engineer why would you EVER have bought into the "6800" in the first place?

Dedicated hosting.

They're the new 'low-end' high throughput firewall my company offers to customers since the 5510-5550's are EOL.

You probably got them for a refresh if Cisco had a sweet bundle price for them at any point

Well when my Cisco SE was pitching the 6800's to refresh our Datacenter 6509's I laughed at him as a mid-level engineer, and we went with Nexus instead. The final say wasn't mine, but my laughter was taken into consideration.

For access, we went 4510's IIRC.

If you were building out a new small datacenter environment, would you go with two independent 10Gbe switches and use nsx or something similar to build layer two overlays, would you go with a chassis switch like a 9k, or would you do two independent 10Gbe switches and use mlag or VPC? I know leaf spine and layer 2 overlay is the new hotness, but I don't want to do something unnecessary here.

Assume the following:

12 VMware hosts (6 for VDI and 6 for server virtualization)
2 HA SANs, and 4-5 metro ethernet carriers
No more than 25% growth over the next 5 years
We do a lot of virtual routing already with VyOS/quagga

I know this is a complicated question, I'm just looking for some general thoughts.

# ? Feb 11, 2017 19:51

psydude: Apr 1, 2008; Heartache is powerful, but democracy is *subtle*.

NSX is a pretty expensive solution for 12 VM hosts and no real need for microsegmentation.

I thought vmware recently dropped the price considerably, is it still pretty expensive even after that?

# ? Feb 11, 2017 21:23

psydude: Apr 1, 2008; Heartache is powerful, but democracy is *subtle*.

More expensive than just using 9ks like you mentioned, yes. I don't see what benefit you would get from NSX in an environment that small unless you're trying to meet strict security requirements or are hosting multiple subsidiaries' applications and environments that need to be kept separate in ways that the traditional DC network you detailed cannot.

That's actually what I wanted to hear. I was mostly worried that I was considering "the old way" when I should have been looking at the newer poo poo instead. Good to know that some designs are timeless.

I love neat next generation networking poo poo as much as the next guy, but sometimes networking is just networking and all you need is a non-blocking 10GB switch that can do fabricpath or TRILL. Or none of that because most of the time traditional L2 networking is sufficient.

Really don't even need fabricpath or trill. EVPN is pretty much supported on every vendor now and gets you the same sort of capability.

The 6800/6500 platform is basically the cornerstone of the enterprise product line. The NEXUS code is no where near as stable or feature-complete to be a drop-in replacement.

The 6500 was - and is, still - the swiss army knife of the networking world, it does everything at a reasonable price. If they discontinued that product line I have no idea what's going on at CISCO but it's bad.

The 6k's been around since 1999, it's time to let go. They tried to keep it relevant by ditching classic bus and doubling up on fabric channels (hooray, now you have DFCs everywhere which doubles line card costs) but as a flagship product it's days are numbered unless they do a ground up rebuild (and at that point just make a new product and be done with it). VSS is inferior to vPC, and routing BU withdrew their support for the platform when they moved to ezchip and doubled down on the 9k. If they do replace it, I imagine we'll see something built primarily around merchant silicon with a custom ASIC for features, but DC switching has a few years on them in that department.

VPC better than VSS? Whaaaat

If you're just using it as a switch then yeah the 7k is better but the 6800/6500 is (or was, at least) far superior as a routing platform which is what made it so desirable.

Ethernet is so ubiquitously deployed that there's only need for switches to do dumb transport. Everything else can be done on hosts.

To each his own, but you're still using a switching-oriented platform to do routing and you're stuck on classic IOS to boot. If I wanted a modular router I'd be looking at something like ASR 1000 or 9000.

I thought the 4500 was supposed to replace the 6500 for Enterprise LAN Switching. Or was there some kind of inter-BU fuckery that torpedoed that idea?

I agree, but if I'm not mistaken the price of the ASR range is orders of magnitude higher.

edit: just looked, and yeah an ASR eclipses the 6800 line in price. An ASR1004 without any linecards or licensing any of the 10G ports costs over twice as much as a 6840.

Sure, the ASRs go a lot higher but there are closer alternatives to be used for this example like an ASR9001. Not that they're directly comparable anyway, the 6840 has more port density, but I was mainly just lamenting using a classic IOS platform at this point.

We use VyOS pretty heavily, and it works great. We still have fortigates for perimeter firewall, but do our BGP exchange on VyOS (and have for years).

For a data center you can do most of everything you'd need to do on a 7k/9k. We've been doing a lot of Nexus and Arista in the data center and doing HP, Brocade and occasionally Juniper for campus. It's worked out well for us!
