• Question 151:

  How many linked targets, per source, are allowed when using TimeFinder SnapVX?

  A. 128

  B. 256

  C. 512

  D. 1024

  Correct Answer: D

  To access a point-in time-copy, create a link from the snapshot data to a host mapped target device. SnapVX supports up to 1,024 linked targets per source device. Links can be a permanent copy on a target device, or a temporary copy that no longer retains the point-in-time copy of the data once the link is removed.
