Explanation

Simplifying the data center network architecture In the core of the network, HP 12500 switches can be deployed in conjunction with IRF to completely eliminate the aggregation layer found in conventional three-tier data center networks. IRF overcomes the limitations of legacy spanning tree networks by fully leveraging all network connectivity (no inactive backup paths) and by providing rapid failover to dramatically improve network utilization and performance in the network core. A collapsed, two-tier data center network architecture enables direct-flight server- to-server performance, requires significantly fewer connections and port counts (no aggregation switches), streamlines provisioning and network management, and reduces capital expense and energy consumption (D). In addition, these two- tier networks provide large Layer 2 domains to enable VM migration across the data center (move workloads from one server to another server in the same VLAN/IP subnet.)
