Maybe it's the wrong question, but I remember from other drive types that once you drop into start-stop mode (or shuffling), the throughput goes through the floor. Our SE thought that a 7000 being fed below streaming speed might be actually slower than a 4000 being fed at the same speed.
I agree that network backup is not great, but we're managing (just about) to get it to work at the moment using amanda and exabytes. I'd like to keep to one system, so we'll probably modify amanda to use the DLT (either locally or on the filer).
Has anyone any hard figures for backup speeds both locally on a filer and remotely via 100Mbps ethernet and rmt or rsh? We don't have anything that supports NDMP at the moment, but might consider Budtool, though it doesn't support all the machines we have at the moment.
Our main interest in the 7000 is capacity (single tape backup at the moment), rather than speed.
Bruce> PS - Is the 7000 even supported on the F230?
I'm told that they've now released a wide card supported on the F230 in the latest release, so you can attach a 7000. -- Alan
