Specifications

OpenVMS VAX Operating System, Version 5.5-2 SPD 25.01.37
In-cabinet upgrades are supported with OpenVMS li-
censing. When upgrading a processor, the customer
is required to upgrade the operating system licenses.
For OpenVMS, this is accomplished with a BASE up-
grade license that upgrades the O/S BASE license and
permits the use of all "specified quantity" (e.g., 4 user)
interactive licenses on the processor. For unlimited user
licenses, an additional upgrade license for Unlimited In-
teractive User is required.
The OpenVMS O/S Base and Interactive Use licenses
are not supported by VMS or OpenVMS operating sys-
tem releases prior to OpenVMS Version 5.5.
Digital provides the proper license type with the pur-
chase of the system. Not all OpenVMS license types
are available for all system models.
License Management Facility Support
The VMS Operating System supports the License Man-
agement Facility.
If no VMS license is registered and activated using the
License Management Facility, then a single login is per-
mitted for system management purposes through the
system console (OPA0:).
Several of the VAX VMS and OpenVMS license types
are based on the number of concurrent users, called an
activity license. Every product has the option to define
an activity as related to the License Management Facil-
ity. OpenVMS defines activities, sometimes referred to
as an OpenVMS "user," as follows:
• Each remote terminal connection is considered an
activity. This is true even if you set host to your local
node (SET HOST 0).
• Each connection from a terminal server is considered
an activity.
• A multiple-window session on a workstation is con-
sidered one activity, regardless of the number of win-
dows.
• A batch job is not considered an activity.
• A remote network connection that is a connection
other than a remote terminal connection, is not con-
sidered an activity.

SUPPORTED HARDWARE FOR VMS, VMS
DECwindows, VAXcluster, and DECnet–VAX
This section of the SPD contains four parts: Hardware
Charts, Appendix A, Appendix B, and Appendix C.
The charts list the hardware that VMS, VMS DECwin-
dows, DECnet–VAX, and VAXcluster Software supports.
Combinations of hardware options are subject to limi-
tations such as bandwidth, physical configuration con-
straints, and electrical load and power supply.
Appendix A describes system-specific restrictions for
the configurations listed.
Appendix B describes Digital terminals, disks, tapes,
controllers, communications options, and VAXcluster
options. Some restrictions for specific devices are listed
if applicable.
The content of this hardware configuration appendix is
intended to specify the device limitations and provide a
general guide. It does not describe all possible hard-
ware configurations or circumstances. Any particular
configuration should be discussed with Digital. Contact
Digital for the most up-to-date information on possible
hardware configurations.
Digital reserves the right to change the number and
type of devices supported by VMS, VMS DECwindows,
DECnet–VAX, and VAXcluster Software. The minimum
hardware requirements for future versions and updates
of VMS, VMS DECwindows, DECnet–VAX, and VAX-
cluster Software may be different from current hardware
requirements. For configuration details about VAX hard-
ware, refer to the VAX System and Options Catalog and
the Networks and Communications Buyers Guide.
Refer to the individual SPDs for DECnet–VAX (SPD
25.03.xx) and VAXcluster Software (SPD 29.78.xx) for
detailed product information.
How to Read the Charts
The first column lists the VAX system, the media (tape,
disk, or compact disc) from which the VMS Operating
System can be loaded onto the system disk, and the
maximum number of busses supported on the system.
The second column lists the disk controllers and drives
that can be used on the system. A disk controller can
be used with any disk drive listed next to it: for example,
on a Micro/VAX II or VAXstation II system the RQDX3
