Storage Oversubscription ratio

Considerations
• Switches are rarely the bottleneck in SAN implementations
• Device capabilities (peak and sustained) must be considered along with network oversubscription
• Must consider oversubscription during a network failure event

Recommendation:

Use of Port-Channels and F-Port Channels with NPIV to provide the bandwidth to meet oversubscription ratios
