ABC.com is planning a second data center 20 miles (30 km) away. The second site is intended as
both a disaster recovery (DR) site and a second tier data repository for less important data.
Average latency between sites is less than 20 ms.
As part of the information gathering process, you determine that this customer can accept up to 30
minutes of data loss. The company has a total of 120 LUNs that will need to be replicated.
You have gathered Navisphere Analyzer data for a normal working day. You note the following
values:
Write response time: 5ms
Read response time: 14ms
Write/s: 400
Read/s: 700
CLARiiON CX3-80 in both data centers
FLARE 26
No clones will be used
Which solution do you recommend?

A.
UseMirrorView/S to replicate data to the DR site

B.
Use Incremental SAN Copy to make incremental copies to the DR site every 30 minutes

C.
Clone each of the LUNs and useMirrorView/A to perform an incremental copy from the clones
every 30 minutes

D.
UseMirrorView/A to replicate production data to the DR site
