Why ``Rightsize'' ?
Despite the commonly held view that there is no very long-term future for large scale services based on VMS, the Division has publicly committed to running a VXCERN service for the lifetime of the LEP experiments (at least until 1998). The VAX mainframe and associated HSC hardware are rapidly becoming outdated and are starting to look more and more expensive from the point of view of maintenance costs. The implications of not upgrading the existing hardware are financially very unattractive in the medium term.
A rightsizing will leave us with a Mixed Architecture VMS Cluster (MAVC) of VAX and Alpha workstations. A VAX component is retained since VAX binary compatibility will be essential for some applications during the transition phase to Alpha. A major cost saving is achieved by replacement of the RA-series disk subsystem by modern, cheap SCSI units.
