For example, one university in the Washington, D.C, area charges outside users according to a two-factor formula based on how many "VAXcluster
CPU minutes" and "Disk Kilo-block days" they use.
An NFS File Server was added to VAX 8800 software in stress analysis so that the Hewlett-Packard and Apollo workstations could use the VAXcluster
's shared disk drives for data storage.
The Jnet software running on the university's now-four-machine VAXcluster
is virtually transparent to most users.
configuration of dual VAX 11/785 processors.
The IBM Sysplex and original Digital VAXcluster
typify this design.
However, we have recently accomplished our goals by linking six VAXstation 2000s and a MicroVAX II into a VAXcluster
. Within this cluster, the MicroVAX II serves as a central node and is the only machine that needs a copy of the system software and the Tutor software.
This trend toward generalization in SAN systems was also seen more than 15 years ago in Digital Equipment Corp.'s VAXclusters
, which first used a proprietary physical interconnect (VAX-CI), then moved to the more standard and more general-purpose Ethernet .
The most relevant paper, which inspired the best of the algorithms that we propose, describes the adaptive locking algorithm used by Digitars Rdb/VMS system for VAXClusters
Integrated networks, such as Locus , Apollo Domain , Newcastle Connection , VAXclusters
, and Eden , provide transparent access to network computing or storage facilities.
