Re: [j-nsp] high 10GE port density in EX switch?
Only thing with the EX4550's is that they're only supported by latest (read: bleeding edge) code. Nonetheless, I'm adding them in multiple VC's in two locations where we had only EX4500's. Not the perfect switch, but the VC tech has been sound for years with EX. If you're really curious, ask me in two weeks how those implementations go (one is two VC's of 3 ex4550's, and another is two vc's of 1 ex4550 with 6 ex4200's.

With 10GE and VC modules released. The 40GE module should debute somewhere this year (so they keep telling me). If you're going the _physical_ VC route with VCP ports it would give you 2.5:1 oversubscription (32 x 10Gbps vs 4 x 32Gbps). Going VCPe you can do a bit better with 2:1 oversubscription. If doing that look into the traffic patterns to figure out how far you can stretch the Virtual Chassis (max 10 members) before creating contention. I haven't seen official specs for the EX9200 yet, but supposedly that should fill the gap between EX8200 and MX I'm told. Apart from Qfabric itself, the QFX3600 with MC-LAG might also be a nice consolidation layer with its 16 QSFP+ ports between an MX and a bunch of VC'd EX4550's. Don't know if the routing on there (with VRRP and filtering) is beefy enough for the needs. In the end it boils down to not just the port-count, but the traffic and usage patterns. Unfortunately those aren't always that clear up front (or even in hindsight ;D).

There is always the EX4550, 32 10Gb ports in 1U, with a module to add 8 more I believe On Sat, Feb 2, 2013 at 1:43 PM, Eugeniu Patrascu wrote: > On Sun, Dec 16, 2012 at 4:13 AM, Michel de Nostredame > wrote: >> Hi There~ >> >> One of my customers has some Cisco Nexus 7K but budget wise prevents >> him from buying N7K in new locations.

It's oversubscribed 5:1 in 5x8 port groups. Another option for a lot of 10G ports would be a stack of EX4500 switches, but you would still be limited by the Virtual Chassis available bandwidth (128Gbps Half-Duplex) - but if you can get some flexibility as you can try to mix and match servers that talk to each other on the same switch in order to have line rate 10G traffic and avoid VC traffic. You can use the up-link modules to populate them with 10G ports and do a MC-LAG to the MXs. Even with the QFabric, you would still need to run a lot of 40G interconnect ports in order to have a high throughput fabric backplane. Other vendor that might do (you should check with them) full line rate 40+ 10GbE ports is Brocade with the new VDX 8770-8 switch (they claim 4Tbps/slot and 384 ports per 15U chassis).

[j-nsp] high 10GE port density in EX switch?
Hi There~ One of my customers has some Cisco Nexus 7K but budget wise prevents him from buying N7K in new locations. His environment is pretty simple and straight forward. Lots of 10GE ports (around 2200 ports) divide into around 30+ VLANs. Then uplink to two MX routers (the border) and go to Internet. Previous setups were using N5K as L2 access switch and aggregate to N7K as core L3 switch, then multiple 10GE L3 uplinks to MX480. The N7K is doing VLAN routing and lots (total 3+ thousand lines) of ACL. The QFX total solution looks pretty interesting, but does not have too significant price difference compares to Nexus solution. Will Juniper ship new switch fabric on EX 8000 series to support line-rate high port density 10GE? (for example, 40 port line rate 10GE per slot.)
