A customer wants to connect two data centers for disaster recovery purposes using asynchronous mirroring. The customer is about availability and cost of dark fiber between the two sites.
Which IBM Storwize family feature should the IBM representative highlight to ease customer concerns?
A . High availability architecture
B . Cascading FlashCopy
C . Three site disaster recovery
D . IP-based replication
Answer: D
Explanation:
IBM Storwize Family Software V7.2 introduces replication over IP networks that is easy to configure in existing IP infrastructures. This is a lower-cost alternative to the Fibre Channel-based and FCoE-based replication, eliminating the need for FCIP routers and dark fibre. By placing the IP replication function in the Storwize Family Software, server CPU and management overhead is freed up, and a single point of replication control is available for all server types. This release also includes SAS migration capability for the Storwize V5000, Storwize V3700, and Storwize V3500.
