We run Cloverleaf 3.8.1P on Tru64 4.0g in a non-clustered environment. Currently it seems to be running fairly well, but as I understand it this is the last Tru64 version supported. We are investigating HA options, probably looking at either HP/UX or Linux. I really like Tru64 and feel that it would probably work as well as any other OS or better, but the lack of support will probably drive us to another OS….
