Volume Shadowing Per-Disk License

HIGHLIGHTS

o  Per-disk licensing now available for both OpenVMS VAX and OpenVMS AXP
   platforms

o  Capacity licenses still obtainable for users with large disk farms

PRODUCT DESCRIPTION

With the release of the OpenVMS V6.1 operating system, volume shadowing now
is available via both per-disk and capacity licenses on the OpenVMS VAX (SPD
27.29.xx) and OpenVMS AXP (SPD 47.04.xx) platforms.

The availability of both per-disk licensing and traditional capacity
licensing gives users a choice: They can either purchase capacity licenses
for each CPU that accesses shadowed data or purchase licenses for each disk
that they wish to include in a shadow set. If they purchase the latter way,
each disk in a shadow set will require one per-disk license regardless of
the size or type of the disk.

Per-disk licensing is based on the concurrent use method, but instead of
people being counted, disks are counted. A two-member shadow set requires
two per-disk licenses, and a three-member shadow set requires three per-disk
licenses. Purchasing one per-disk license per shadow set is not sufficient.

For further information, please consult the "Volume Shadowing for OpenVMS
AXP V1.5" article in the October 25, 1993, issue of Digital's Customer
Update.
