APPRAISAL DATA Summit7i™ The high-density Summit7i stackable switch delivers non-blocking wire-speed IP/IPX routing and switching to server farms, aggregated switches and network backbones. Available with 28 100/1000BASE-T or 1000BASE-SX ports plus four GBIC-based 1000BASE-X ports, Summit7i provides 32 ports of non-blocking Gigabit Ethernet with full routing protocol support in a compact 4U package. It also comes with optional redundant power supplies for increased fault tolerance.  Switching Co-location and Switching In server farms and data centers, the Summit7i maximizes server availability and performance by combining server load-balancing with wire-speed switching. Auto-negotiating 100/1000BASE-T ports extend the simplicity of Ethernet’s scalable speed from Fast Ethernet to Gigabit Ethernet. The low 7-inch height of the Summit7i also makes it ideal in server farms and data centers where rack space is limited. Scalable Backbone Bandwidth The high port-density of the Summit7i makes it easy and cost-effective to scale backbone bandwidth and aggregate multiple switches. As a “mid-tier” switching solution, Summit7i can aggregate multiple Summit access switches, while providing high-speed gigabit links to BlackDiamond® chassis switches in the core. Utilizing link aggregation, Summit7i can trunk multiple Gigabit Ethernet connections into one high-bandwidth pipe. Capable of scaling backbone bandwidth well into the future, the Summit7i can aggregate up to eight Gigabit Ethernet links into one logical link. Resilient Aggregation Supporting critical redundant link resiliency at Layers 2 and 3, the Summit7i is an ideal high performance aggregation switch. At Layer 2, EXTREME Automatic Protection Switching (EAPS) provides sub-second resiliency necessary to support converged services such as Voice over IP. Additional resiliency options at Layer 2 include Spanning Tree Protocol (STP), IEEE 802.1w Rapid Spanning Tree (RSTP), Per-VLAN Spanning Tree Plus (PVST+), and EXTREME Multiple Instance Spanning Tree (EMISTP) to optimize Layer 2 resiliency and availability. The Summit7i also provides the option for full-bandwidth non-blocking Layer 3 resiliency using OSPF Equal Cost Multi-Path. Pre-installed on every EXTREME Networks® switch, the EXTREMEWare® software suite combines industry standard protocols to ensure interoperability with legacy switches and routers, plus Policy-Based Quality of Service (QoS) for bandwidth management and traffic prioritization in today’s networks. Every switch includes EXTREME Automatic Protection Switching (EAPS) for Layer 2 resiliency which provides very rapid failover necessary to properly support converged services. Optional on Summit7i is a Full Layer 3 EXTREMEWare license which provides a complete set of routing protocols that deliver the Layer 3 routing and resiliency required for aggregation or core deployment.   Summit7i Feature Set Non-stop reliability of critical ENTERPRISE applications through EAPS resiliency 64 Gbps non-blocking switch fabric bandwidth Wire-speed IP/IPX routing at 48 million packets per second Wire-speed RIP v1 and v2, OSPF, BGP4, DVMRP and PIM routing, essential for core or aggregation deployment 32 Gigabit Ethernet ports: 28 auto-negotiating 100/1000BASE-T or 1000BASE-SX ports, plus four GBIC-based 1000BASE-X ports supporting short to long reach Gigabit optics Policy-Based Quality of Service, including bandwidth management and prioritization Access policies for network control and security Server load balancing and web cache redirection Fault tolerant: multiple load-sharing trunks; multiple spanning trees; EXTREME Standby Router Protocol; and redundant, load-sharing power supplies Extensive management through HTTP, SNMP, RMON, and command line interface ESRP provides resiliency at both Layer 2 and Layer 3 VRRP for standards-compliant dual homing Full OSPF, and OSPF Equal Cost Multi-Path routing 4,096 IEEE 802.1Q VLANs IEEE 802.1ad compatible link aggregation Switch and route jumbo frames   Summit7i Product Specifications General   Security -
