ABC.com has a DR site 20 miles (30 km) from their production site. Each site has a CX3-40. As
part of the information gathering process, you determine that their RPO is 15 minutes or less.
They have a total of 30 LUNs that will need to be replicated to the remote site. Their application is
sensitive to response times.
You have gathered Analyzer data for a normal working day. You note the following Analyzer
values:
Write response time: 5 ms
Read response time: 14 ms
Write/s: 400
Read/s: 700
Average seek distance: 23 GB
Which solution should you recommend?
A.
Clone each of the LUNs and use SAN Copy to perform a full copy from the clone every 15
minutes
B.
Create a synchronous mirror for each LUN and ensure that they remain synchronized
C.
Clone each of the LUNs and use SAN Copy to perform an incremental copy from the clone
every 15 minutes
D.
Create an asynchronous mirror for ach LUN and set the update interval to 15 minutes
