What is the minimum bandwidth requirement for replicating volumes between PowerFlex clusters?

Question

Options

• A1 Gbps
• B10 Mbps
• C100 Mbps
• D10 Gbps

• A
  86% (43)
• B
  8% (4)
• C
  4% (2)
• D
  2% (1)

Explanation

PowerFlex requires a minimum of 1 Gbps of dedicated bandwidth between clusters to support volume replication reliably - this ensures sufficient throughput for continuous data synchronization without becoming a bottleneck during peak I/O workloads.

• 10 Mbps (B) is far too low for enterprise storage replication and would cause severe lag or replication failure under any meaningful workload.
• 100 Mbps (C) might seem plausible for smaller setups, but PowerFlex is an enterprise-grade platform where 100 Mbps would quickly become a bottleneck.
• 10 Gbps (D) is a reasonable network speed in modern data centers, but it is not the minimum requirement - it exceeds what the spec mandates.

Memory tip: Think "1 Gbps = 1 Gig minimum for replication." PowerFlex is enterprise storage, so associate it with enterprise-grade networking - anything below 1 Gbps belongs to a different era.
