Hi Joe You guys ever mount your racks on Barry mounts= vibration mounts..with so many shakes you may need to. RD

We had a 6.2 last year in Costa Rica... We immediately regretted where we had placed our racks and are almost finished a project to move them to a concrete floor (rather than that compressed cardboard stuff). Lost a lot of hard drives that day! We regularly have quakes between the 4-5 region here. By regularly, i mean a minimum of 5 times a year in different parts of the country.
If there is interest in data centre provisioning or construction, disaster planning or inside/outside plant strategies intended to mitigate damage by earthquakes then the NZNOG list might well be a good English-language place to get some advice.
Earthquakes of magnitude 4 and up happen pretty regularly (several times per week is common).

Can someone from the Cogeco NOC please contact me off-list at roccap2005@yahoo.com? I have tried ipservices@cogeco.net and 1-905-333-7055 without luck. Thank you.

Very interesting to see about A10's performance- I've heard mixed things about them.
Just an FYI, the newer F5 platforms don't utilize the ASIC's- the performance curve of general-purpose CPU's has once again eclipsed what can be done with specialized silicon without aggressive (and expensive) revision cycles. The ASIC's also could only be used in simpler virtual server configurations and with certain subsets of iRules.
That said, nothing else I'm aware of provides the functionality of iRules. I've used netscalers only a relatively small amount- and they are nice- particularly if your requirements are within their feature set- but my experience has been that things I take for granted using an iRule are seriously painful to implement on a netscaler.

When we put them head to head A10 AX3200 vs F5 6400 ltm (note: 6400 was what we were looking to replace)
Test: 1000 concurrent users from Gomez's Networks Loadtesting platform hitting as fast as the requests would close, going through our standard vip config on the f5, and the A10 engineering teams 3 best efforts to beat that config that balanced between two Identical Dell 1950 servers serving a php page that responded with a random number (to avoid caching). The 6400 we used was in production at the time, and was older so we were expecting to get blown away, see the results here:
F5 - Peaked 160k completed transactions a minute sustained for 10 minutes, 0 errors, 112ms average transaction response time A10 - Held 60k completed transactions a minute sustained for 10 minutes, 0 errors, 360ms average transaction response time
If anyone is interested in the graphs I think I can still pull them out of gomez. Though notable that this was all done a year ago, so things might be different now.

Does anyone have any experiences good/bad/indifferent with this company and their products? They claim 2x the performance at ? the cost and am a bit leery as you can imagine.
We are looking to replace our aging F5 BigIP LTM's and will be evaluating these along with the Netscaler and new generation F5 boxes.

Yes, agreed. I think the Netscaler falls into the category of the Cisco in this respect <ducks>. Seems the F5 gear is the 1000lb gorilla in this category and for the most part we have no reason to look anywhere else other than doing our own due diligence with respect to the other vendor offerings in this space.
