Is it the collapsed optical backbone switch, or the upstream L3 element, or perhaps both? I am talking about the matter that the following topology: server - 5 meter UTP - switch - 20 meter fiber - switch - 20 meter fiber - switch - 5 meter UTP - server has worse NFS performance than: server - 25 meter UTP - switch - 25 meter UTP - server Imagine bringing this into metro with 1-2ms delay instead of 0.1-0.5ms. This is one of the issues that the server/storage people have to deal with. -- Mikael Abrahamsson email: [email protected]
