Large buffers
provide graceful congestion management
Connectivity
Flexible 10 Gbps Ethernet connectivity
up to four optional 10-Gigabit ports (SFP+ and/or 10GBASE-T)
Two-port stacking module with up to 40 Gbps/port
optional two-port stacking module allows stacking of up to four switch units into a single virtual device
Auto-MDIX
automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports
IPv6
IPv6 host
allows the switches to be managed and deployed at the edge of IPv6 networks
Dual stack (IPv4/IPv6)
provides transition mechanism from IPv4 to IPv6; supports connectivity for both protocols
MLD snooping
forwards IPv6 multicast traffic to the appropriate interface; prevents IPv6 multicast traffic from flooding the network
IEEE 802.3at Power over Ethernet (PoE+)
provide up to 30 W per port that allows support of the latest PoE+-capable devices such as IP phones, wireless access points,
and security cameras, as well as any IEEE 802.3af-compliant end device; eliminates the cost of additional electrical cabling and
circuits that would otherwise be necessary in IP phone and WLAN deployments
Pre-standard PoE support
detects and provides power to pre-standard PoE devices
Dual-personality functionality
includes four 10/100/1000 ports or SFP slots for optional fiber connectivity such as Gigabit-SX, -LX, and -LH, or 100-FX
Performance
Energy-efficient design
High-efficiency power supplies
80 PLUS Silver Certified power supply increases power savings
Energy-efficient Ethernet (EEE) support
reduces power consumption in accordance with IEEE 802.3az
HP ProVision ASIC architecture
is designed with the latest HP ProVision ASIC, providing very low latency, increased packet buffering, and adaptive power
consumption
Selectable queue configurations
allows for increased performance by selecting the number of queues and associated memory buffering that best meet the
requirements of the network applications
Software-defined networking
NEW OpenFlow
supports OpenFlow 1.0 and 1.3 specifications to enable SDN by allowing separation of the data (packet forwarding) and control
(routing decision) paths
Convergence
IP multicast snooping and data-driven IGMP
automatically prevent flooding of IP multicast traffic
