[AusNOG] 10Gb Switching and HP COMOS5 vs 7

[Jiri Kosar]

Hi All,

from Brocade if you want high-density 10G, I can recommend VDX as well (we do use internally VDX6740) and it has 40G ports too, some nice virtualization/hypervisor and ethernet fabric features, active-active links between fabric members and you can grow-up or scale-down as you like, but it is also worthwhile to mention ICX7750 or ICX6650 as they have 10G or/and 40G ports as well and some IPv6 routing features which are due to be introduced to VDX platform in next few months.

To the list you mentioned, I’d like to also add Arista Networks. It does 10G, 40G and it is ultra-low latency. Additionally, If you have a linux background, you would love EOS operating system (firmware). You can go to linux shell directly from cli on a switch, install RPM packages, do python scripting and you have still your 10G performance and 380ns/less latency between ports. I do have 7124sx at the office and to demonstrate switch flexibility, I have managed to run Windows 8 on a switch using KVM hypervisor ☺))

There is a lots of features what I can talk about, but you can find it on a manufacturer website and I have just mentioned what I thought could be relevant.

I've used Brocade ICX and VDX kit for 10Gbps switching. My preference is their VDX kit, it has been faultless since installation.

Hey all,

Just looking at upgrading some A5820's with A5900's...

Anyone done this and know the differences between COMOS5 and COMOS7?  HP say its backwards compatible, but I am wondering if there are any stories - good or bad - out there about doing it.

Also - what do people think in the 10Gb switching space?

- HP A5900 (48 ports)
- Juniper EX4550 (32 ports)
- Cisco 4500-X (32 ports)
- Brocade equivalent?
- Others?

The HP A5800 has 2mb packet buffers, the A5900 is 9mb.. the Cisco 4900 might have around 17mb, but I can't figure out what the Juniper has... nothing is listed here: http://people.ucsc.edu/~warner/buffer.html to even guess with.
