H3C Intelligent Resilient Framework (IRF2)
Intelligent Resilient Framework 2 (IRF 2) is H3C patented virtualization technology that can virtualize multiple switches into one logical unit and provides the following benefits:
Easy management—IRF 2 provides a single point of management, enables switch plug-and-play, and supports software auto-update for software synchronization from the master to the new member devices. It brings business agility with lower total cost of ownership by allowing new switches to be added to the fabric without network topology change as business grows.
High availability—The H3C proprietary routing hot backup technology ensures redundancy and backup of all information on the control and data planes and non-stop Layer 3 data forwarding in an IRF 2 fabric. It also eliminates single point of failure and avoids service interruption.
Redundancy and load balancing—The distributed link aggregation technology supports load sharing and mutual backup among multiple uplinks, which enhances the network redundancy and improves link resources usage.
Flexibility and resiliency—The switch uses standard 10G Ethernet ports instead of specialized ports for IRF links between IRF member devices. This allows customers to assign bandwidth as needed between uplink, downlink, and IRF system connections. In addition, an IRF fabric can span a rack, multiple racks, or multiple campuses.
Abundant Data Center Features
The switch supports abundant data center features, including:
EVB—The switch realizes the traffic forwarding between virtual machines (VM) and solves the connection and management boundary between the VM and the network via Virtual Ethernet Port Aggregator (VEPA) mode.
TRILL—Helps set up a large, resilient, high-performance Layer 2 network with support for long-distance VM mobility and data mobility.
VXLAN—The switch can operate as a high-performance VXLAN hardware gateway to support multitenant data center services. In conjunction with the H3C cloud management platform, the switch can be used to set up an agile, resilient, highly available high-performance Layer 2 network, with support for long-distance virtual machine mobility, data mobility, and business continuity.
FCoE—Allows transmission of FC packets over Ethernet so that FC SAN services and LAN services can run over the same network infrastructure.
PFC, ETS, and DCBX—Helps provide FC storage and high-performance computing services with low-latency and no data loss.
Flexible Choice of Airflows
The switch provides a front-rear air aisle. By using different fan trays, the switch can provide field-changeable airflows, from front to rear or front rear to front.
The switch provides abundant QoS features, including:
Packet filtering based on packet header fields from Layer 2 through Layer 4.
Traffic classification by source MAC, destination MAC, source IP, destination IP, TCP/UDP port number, protocol type, and VLAN.
The switch uses removable power modules and allows you to select AC or DC power modules as required. The power modules available for the switch have a self-protection mechanism to prevent overcurrent, overvoltage, and over temperature conditions. The switch can detect faults in power modules and fan trays and will generate an alarm when a fault occurs.
The switch supports diverse link redundancy technologies such as H3C proprietary RRPP, VRRPE, and Smart Link. These technologies ensure quick network convergence even when large amount of traffic of multiple services runs on the network.
Outstanding Management Capacity
The switch improves system management through the following ways:
Provides multiple management interfaces, including the console port, mini USB port, USB port, and two out-of-band management ports.
Supports configuration and management from CLI or a mainstream network management platform and H3C IMC Intelligent Management Center.
Supports multiple access methods, including SNMPv1/v2c/v3, Telnet, SSH 2.0, SSL, and FTP.
Supports standard NETCONF APIs that allow users to configure and manage the switch, enhancing the compatibility with third-party applications.
Provides a variety of traffic monitoring and analytic tools, including sFlow, NetStream, SPAN/RSPAN/ERSPAN mirroring, and port mirroring to help customers perform precise traffic analysis and gain visibility into network application traffic. With these tools, customers can collect network traffic data to evaluate network health status, create traffic analysis reports, perform traffic engineering, and optimize resource allocation.
Comprehensive Security Control Policies
The switch supports AAA authentications (including RADIUS authentication) and dynamic or static binding of user identification elements such as user account, IP address, MAC address, VLAN ID, and port number. Using the switch in conjunction with H3C IMC, you can manage and monitor online users in real time and take prompt action on illegitimate behaviors.
The switch offers a large number of inbound and outbound ACLs and VLAN-based ACL assignment. This simplifies user configuration while saving ACL resources.
