Network Integration and Scalablity

• In-path – Installs transparently in-line and provides automatic fail-to-wire

• Out-of-path – “One arm” attachment to routers/switches with direct configuration, WCCP, policy based routing, and L4 switch redirection modes

• Multi-port Interfaces – 4 Port GigE Card available (optional, all models). Up to twelve Ethernet ports per Steelhead appliance (3010 and 5010) support scalability and redundant WAN router and switch configurations

• Asymmetric Routing – Connection forwarding for support of incoming and outgoing route asymmetry

• Network Topology – Full mesh, hub and spoke, and multi-drop topologies supported

• Clustering – Serial (in-path), Parallel (out-of-path), or Virtual In-Path clustering for massive scalability

 Management and Policy

• Configuration – Web UI, command line interface, and Central Management Console (CMC)

• SNMP – SNMPv2 support for monitoring and statistics gathering via MIB II and enterprise MIB

• Comprehensive Logging – Local, CMC, and Syslog support with configurable logging levels

• Marking – DSCP, port, and VLAN mapping and/or preservation

• Reporting – Robust performance statistics gathering, export, and graphical reporting

• Policy – Per-application admission and optimization controls

• Rate Limiting – Settable WAN bandwidth rate control

High Availability and Security

• Fail-to-Wire – Dual watchdog timers ensure no loss in network connectivity in the event of hardware or software failure

• N:1 and 1:1 Redundancy – Hot-standby redundancy and N:1 clustering for in-path and out-of-path configurations

• Redundant Disk and Power – Available RAID and dual power supplies protect the system from hard drive or power supply failure

• Authentication – RADIUS and TACACS+ support for authenticating access

• Encryption – Configurable IPsec encryption for Steelhead to Steelhead communications

• Dual Image SW Upgrades – Scheduled over-the-wire software upgrades with dual image, rollback, and scheduled restart/reboot
