Network availability questions

+ How do you backup your network today?• Spanning Tree (too complex? slow convergence time? Does it even work?)

• Stacking, Distributed link aggregations, active-active server topologies?

+ What happens when parts of your network are down?

+ What is the cost of downtime today? And tomorrow?

+ How critical is the network uptime? Single points of failure?

NETGEAR Stacking = Virtual Chassis

Stacking benefits

Highly Scalable:

• Switches can be ‘stacked’ with high-speed shared bandwidth

• Dedicated ports for stacking connectivity; don’t waste valuable user ports

• Support distance / remote stacking needs across multi-sites

Intelligent and Easy Management:

• Single IP Address management for entire stack

• Stack-master maintains configuration for all members

• Stack-master automatically synchronizes software for all members

Highly Redundant

• In Ring configuration, stack stays alive in case of failure of any switch

• Failover mechanism in case master fails

• Hot swappable solution

Stacking:Limitations

+ Resources are reduced to master of the stack.

+ Proprietary solution

Education on Availability

+ All about how to get rid of Spanning Tree ‘backup’

+ Spanning Tree is slow and too complex for midsize networks

+ Stacking allows for distributed link aggregations hence providing load-balancing AND redundancy / failover capabilities

+ Stacking is all about how FAST the recovery must be

Education on Availability

+ Stackable Smart Managed can offer ‘reduced’ downtimes

+ Stackable Fully Managed can offer NSF sub-second failovers’

+ Chassis Switches will allow for Non-Stop-Forwarding in any situation with added predictability over stack (fixed architecture) and more efficient N+1 power redundancy

Stacking Availability – facts

+ What is your downtime expectation for devices and clients connected to the stack in case of a switch failure?
