Data Center testing

Does any one know of any data centers that do failure testing of their networking equipment regularly? I mean to verify that everything fails over properly after changes have been made over time. Is there any best practice guides for doing this? Thanks, Dan

Re: Data Center testing

I know Peer1 in vancouver reguarly send out notifications of "non-impacting" generator load testing, like monthly. Also InterXion in Dublin, Ireland have occasionally sent me notification that there was a power outage of less than a minute however their backup successfully took the load. I only re

Re: Data Center testing

We have done power tests before and had no problem. I guess I am looking for someone who does testing of the network equipment outside of just power tests. We had an outage due to a configuration mistake that became apparent when a switch failed. It didn't cause a problem however when we did a p

Hello all, We are working on fine tuning drop profiles for customer edge routers (Juniper J-2320 in almost all cases) and I was hoping for some input from those who are smarter and have done this before. Basics: - Sites each have a single T1 into a service provider L3 VPN - Queue depth is 5

FCCs RFC for the Definition of Broadband

I read an article on DSL Reports the other day ( http://www.dslreports.com/shownews/FCC-Please-Define-Broadband-104056), in which the FCC has a document requesting feedback on the definition of Broadband. What are your thoughts on what the definition of Broadband should be going forward? I would a

RE: Alternatives to storm-control on Cat 6509.

In my opinion the Sup32 platform has some limitations when the technology is considered for high data rate, deterministic carrier customer-facing scenarios. Cisco sells the Sup32 as a wiring closet aggregation switch the main purpose of which is to connect desktop users to central core switches. In

RE: Data Center testing

Thanks for the kind words Ken. Power failure testing and network testing are very different disciplines. We operate from the point of view that if a failure occurs because we have scheduled testing, it is far better since we have the resources on-site to address it (as opposed to an unplanned
