The Question is:
Can you use volume shadowing to mirror two set disks connected to two separate
ALpha systems over a 10 KM distance?
The Answer is :
Assuming the two systems are clustered, yes.
For details of the OpenVMS Cluster distance requirements, please
see the OpenVMS Cluster Software Product Description (SPD) -- the
current maximum cluster node separation support limits are rather
further apart than 10km -- both for the standard clustering and
for the disaster-tolerant cluster configurations.
