Had not heard of such a beast. Did a simple google, found another one from ?Comtech? at aha.com. If I read the two pages correctly, indranetwork claims 450MB/sec while aha claims 3000MB/sec. Seems like they supply an alternative gzip, "ahagzip", that interfaces to their hardware driver. I suspect you would have to either replace gzip with their version, or recompile amanda pointing it to the accelerated version of gzip. If you go the latter route I'd do the recompile with a configure pointing to a standin for either, like /usr/local/libexec/amgzip. It could start out being a simple copy of /bin/gzip til certain amanda was working. Then replace it with the accelerated version for testing. I'll bet you could contact the companies and tell them you are a contributer to the amanda mailing list. That you would like to do an evaluation of their product to confirm its value and suitability for use in amanda installations. Promise to write an evaluation that you will publish one the list and that you will forward to them a copy. Gee Kai, I'd like for you to be a guinea pig for the list :)) jl -- Jon H.
