Hi, After speaking with a number of people offlist after the discussion of low-cost, carrier grade, high-redundancy hardware for Asterisk, I decided that the fastest option would be to take it into my own hands and have a solution designed and manufactured. We are near completion of the solution; which is based upon carrier-grade blade's, which hot-plug into chassis. This allows for both small scale development and large scale expansion. From the basic chassis, with one hot-swap PSU, to the top line chassis with 3 hot-swap PSU's. Blades can be dedicated to specific tasks - like an engine just for Asterisk, an engine just for MySQL and billing, an engine for files storage (voice mail etc) and so on. The basic chassis starts with 4 slots, so an engine running Asterisk, and 3 communications cards. Or 3 networking cards for integration into bigger networks! We're also looking into ways of getting Digium Wildcard's intro the chassis, which will help keep the price point for E1/T1 solutions even lower. Of course, the primary factor is cost; and the intention from the outset was to find a solution that could be something for everybody. And it look's like it can be. Upgrading chassis is a minimal cost too - significantly less that buying replacement servers and switches. And it has high-redundancy. In fact, we are planning to use the smaller profile chassis solutions as web servers and also expand our public VoIP gateways (which are co-located in our web data centre). Send me a mail if you want to be kept uptodate with the progress, or if you are interested in participating in the beta program. Regards, Ad.
