The HP 5120 EI Switch Series is comprised of Gigabit Ethernet switches that support static Layer 3 routing, diversified services, and IPv6 forwarding, as well as provide up to four 10-Gigabit Ethernet (10GbE) extended interfaces. Unique Intelligent Resilient Framework (IRF) technology creates a virtual fabric by managing several switches as one logical device, which increases network resilience, performance, and availability, while reducing operational complexity.

These switches provide Gigabit Ethernet access and can be used at the edge of a network or to connect server clusters in data centers. High scalability provides investment protection with two expansion slots, each of which can support two-port 10GbE expansion modules.

High availability, simplified management, and comprehensive security control policies are among the key features that distinguish this series.        

Funkce

Quality of Service (QoS)

Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic
Advanced classifier-based QoS: classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information; applies QoS policies such as setting priority level and rate limit to selected traffic on a port, VLAN, or whole switch
Powerful QoS feature: supports the following congestion actions: strict priority (SP) queuing, weighted round robin (WRR), and SP+WRR
Traffic policing: supports Committed Access Rate (CAR) and line rate

Management

Friendly port names: allows assignment of descriptive names to ports
Remote configuration and management: enables configuration and management through a secure Web browser or a CLI located on a remote device
Manager and operator privilege levels: provides read-only (operator) and read/write (manager) access on CLI and Web browser management interfaces
Command authorization: leverages HWTACACS to link a custom list of CLI commands to an individual network administrator's login; also provides an audit trail
Secure Web GUI: provides a secure, easy-to-use graphical interface for configuring the module via HTTPS

Connectivity

Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
Flow control: provides back pressure using standard IEEE 802.3x, reducing congestion in heavy traffic situations
Jumbo packet support: supports up to 9216-byte frame size to improve the performance of large data transfers
High-density connectivity: provides up to 48 fixed 10/100/1000BASE-T ports in a Layer 2/Layer 3 switch
Optional 10GbE ports: deliver, through the use of optional modules, additional 10GbE connections, which are available for uplinks or high-bandwidth server connections; flexibly supports copper, XFP, SFP+, or CX4 local connections

Performance

Nonblocking architecture: up to 192 Gbps nonblocking switching fabric provides wire-speed switching with up to 143 million pps throughput
Hardware-based wire-speed access control lists (ACLs): help provide high levels of security and ease of administration without impacting network performance with a feature-rich TCAM-based ACL implementation
