Beechglen has worked with the same family of HP platforms since 1988. That continuity is the reason we can still diagnose, host, protect and extend environments the wider market has stepped away from.
An HP3000 or HP9000 environment is a host, an operating system, storage underneath it, applications above it, interfaces around it and a recovery position behind it. We work across all of them, which is why problems stop being passed between vendors.
A short conversation about your platform, versions, storage and applications is usually enough for us to say where the risk sits and what we would address first.
