When scripting a snapshot of a 5 TB database, how much time should be allocated for the creation of a mountable copy for streaming out to tape?
A customer, George Adams, of Stimnex, has an XIV system installed at 7001 Lake Circle, and a second XIV system installed at4685 International Parkway, and would like to mirror the two systems. The two locations are approximately 15 kilometers (10 miles) apart. Which mirroring scheme would be the best solution for this customer?
Identify two ways reserved physical disk capacity is used on the XIV system? (Select two)
