You are designing SRDF/S over Fibre Channel between two VMAX3 arrays. The production and remote data centers are 100 km apart. What is the expected write response time delay due to latency?
You are designing SRDF/S over GigE between two VMAX3 arrays. The production and remote data centers are 100 km apart. What is the expected write response time delay due to latency?
A customer wants to implement SRDF/S for an application. The application is performing at 12,000 IOPS and is using many volumes. The size of the I/O is 4 KB. Thirty percent (30%) of the IOPS are writes. Assume an RA can handle a maximum of 4,000 4 KB IOPS.
Based on best practices, how many RAs should be recommended?
