What is the recommended solution?
A customer needs to configure SRDF/S between two sites 10 km apart. The customer connected the R1 ports to fabric-A at site 1 and the R2 ports to fabric-B at site 2. The customer does not want to merge the two fabrics between sites.
What is the recommended solution?
What is the expected write response time delay due to latency?
You are designing a Symmetrix VMAX SRDF/S over Fibre Channel solution. The production and remote data centers are 50 kilometers apart. What is the expected write response time delay due to latency?
What is the expected write response time delay due to latency?
You are designing a Symmetrix VMAX SRDF/S over GigE solution. The production and remote data centers are 100 kilometers apart. What is the expected write response time delay due to latency?
How many T3s links would you recommend?
You are designing an SRDF/S solution. The workload profile is:
Total I/Os per second = 10000
Write % = 25
Read block size = 8 KB
Write block size = 8 KB
Network bandwidth can be purchased in increments of single T3 (45 Mb/s) links. Data compression is not in use. How many T3s links would you recommend?
What will significantly improve the link service time between the 2 sites?
A customer is using SRDF/S to replicate a Symmetrix VMAX at the production site to the VMAX at the DR site. The sites are connected using a dedicated T1 link and are 38 km apart.
What will significantly improve the link service time between the 2 sites?
How many OC3 links would you recommend?
You are designing an SRDF/S solution. The workload profile is:
Total I/Os per second = 30000
Write % = 20
Read block size = 4 KB
Write block size = 4 KB
Network bandwidth can be purchased in increments of single OC3 (155 Mb/s) links. Data compression is not in use. How many OC3 links would you recommend?
