Collection of useful, relevant or inane places on the the Internets for 23 Sep 2011:
- OpenFlow Symposium – Applied OpenFlow – Packet Pushers & Tech Field Day – Gratuitous plug for an event I’m organising on OpenFlow and Software Defined Network. Juniper, NEC, Google, Yahoo and more will be attending and talking about their OpenFlow plans and how to use it in real life.
Packet Pushers will be hosting the event in two panel discussions. Greg Ferro, Ethan Banks and Ivan Pepelnjak will acting as hosts and moderators. The event will be held in San Jose and live streamed from the Tech Field Day site using the TechFieldDay professional video crew.
We are planning two panel discussions with one focussed on technology, and the second focussed on Business Applications and Design Scenarios.
- How to reset Grace Licensing in Cisco SAN-OS –
Now I ask that no one do something stupid like try to run this in production. This is for LAB study. This takes time, its not fun to do. However, I will tell you that the average SAN study student will only need to do this at most 1 time. I believe it takes roughly 350-500 hours of on rack time to be fully prepared for the CCIE Storage lab. 120 days of actual runtime is ALOT more than that. So no worries.
Excellent find for people studying FC/FCoE. A valuable addition to building your own lab.
- ASA Bridge Groups – Colby does a great post about using Bridge Groups in the latest verson of ASA to provide a "bump in the wire" firewall. Diagrams, configs. Good to see.
- 365 Days of Blogging – Tom talks about his reasons for blogging. If you want some where to blog, PacketPushers.net is accepting contributions from anyone, feel free to ask how!
- Broacde – Data Center Fabric – Best Practices Guide – Cabling the Data Center. (PDF) – I've found some storage administrators have odd ideas about cabling for SANs. This guide is an excellent reference and demonstrates best practice for setting up a structured cabling system.
- HP Blogs – VXLAN: consider the network virtualization technol… – The HP Blog Hub – Vishwas Manral of HP points out the VXLAN is probably more resource expensive in terms of power consumption and CPU time than the EVB standard. Waiting for the IEEE might require a lot of patience. They haven't delivered much in the last five years.
BTW, we should not forget about the ongoing associated power and cooling costs. The VXLAN solution can lead to considerably higher costs when compared to the EVB solution.
This is not to say VXLAN is never useful. There are certain advantages in the VXLAN solutions too. But before rushing in, vendors trying to use the solution should look at the cost they may have to incur with the increased server usage or increase in the number of servers that may result when the VXLAN solution is implemented.
- Cloud That Shit | Evil Routers –
Like Myspace, Flickr, and Twitter, though, I think the time has come that we begin using “cloud” as a verb:
“The application was moved to an AWS private cloud, defining a new paradigm of increased security best practices and providing a web-scale RESTful API on top of the elastic services FCoTR VPN which, thanks to the on-demand scalability expertise, has resulted in a service-oriented ecosystem with seamless capacity and sustainable ROI.”
Don't think I invented the term "blah blah cloud" I might have heard it somehwere else but I agree with the sentiment. Cloud is boring.
- FCoE: I’m not Dead! Arista: You’ll Be Stone Dead in a Moment! « The Data Center Overlords –
So no, I don’t think FCoE is dead. No-hop FCoE is certainly successful (even Arista’s CEO acknowedged as such), and I don’t think even multi-hop FCoE is dead, but it certainly hasn’t caught on (yet). Will multi-hop FCoE catch on? I’m not sure. We’ll have to see.
I've been saying this since April 2008, and it still hasn't caught on. Neither the Storage or Network markets want to deploy it.
- Cisco IOS Hints and Tricks: You don’t need OpenFlow to solve every age-old problem – People need to keep reinventing the wheel. Ivan points out the LLDP shoul dbe used more often. This means _instead_ of CDP.
LLDP has been standardized years ago and is available on numerous platforms, including Catalyst and Nexus switches, and Linux operating system (for example, lldpad is part of the standard Fedora distribution). Not to mention that every DCB-compliant switch must support LLDP as the DCBX protocol uses LLDP to advertise DCB settings between adjacent nodes.
- Voice Girl Goes to Storage Day « Just another day at the office… –
Contrary to popular sysadmin belief, we network folks are capable of reading and do in fact know what a manual looks like. Contrary to network admin belief, server guys do know what they are doing and don’t just break crap on purpose. Given shrinking IT budgets, device consolidation, and technology overlap, our tiny sandbox has only gotten tinier and now it looks like we’re going to have to share the dump truck and not just the buckets. (the dump truck was always my favorite)
Good summary of TechFieldDay experience. Eye opening. Can't wait for network Field Day next month.
