The Question is:
What is the largest file supported from VMS?
From the OpenVMS FAQ it appears that the largest
disk volume is 1TB but the documentation about
binding volumes together doesn't discuss the
largest bound volume which can be created nor
does it address the size of the largest file
which can be created.
The Answer is :
From the FAQ:
"RMS can store individual files of a size up to the maximum supported
volume size. Under OpenVMS V6.0 and later, the volume size and the RMS
maximum file size limit is 2**31 * 512 bytes -- one terabyte (1 TB)."
From the System Manager's Manual:
"Use a volume set to provide a large, homogeneous public file space.
You must use a volume set to create files that are larger than a single
physical disk volume. (The file system attempts to balance the load on
the volume sets, for example, by creating new files on the volume that
is the least full at the time.)"
Also from the System Manager's Manual:
"You can add volumes to an existing volume set at any time. The maximum
number of volumes in a volume set is 255."
Multi-file databases can potentially permit data stores larger than a
single volume, as well.
