Specs: 48x 1-Gigabit-Ethernet-(GbE-)RJ45-Ports und vier 10-GbE-SFP+-Standard-Ports
Frei wählbare Luftstromrichtung für wesentliche Einsparungen bei den Kühlkosten
Geringe Stromaufnahme von 130 W und variable Lüftergeschwindigkeiten, um den Stromverbrauch zu reduzieren
Integrierte redundante Lüfter, Netzteile und Softwarefunktionen für Hochverfügbarkeit (Standard)

Der Lenovo RackSwitch G8052 verfügt über 48 RJ45-1-Gigabit-Ethernet-(GbE-)Ports und 4 10-GbE-SFP+-Ports in einem flexiblen 1-HE-Switch.
Alle Ports sind standardmäßig vorhanden, die SFP+-Ports können bei Bedarf auch 1-GbE-SFP unterstüzen.
Der G8052 ist auf Höchstleistung ausgelegt und zeichnet sich durch High-Bandwidth-Switching in Leitungsgeschwindigkeit, Filtering und Traffic-Queuing ohne Datenverzögerung sowie große Puffer aus, damit der Datenverkehr im Rechenzentrum reibungslos abläuft.
Redundante, Hot-Swap-fähige Netzteile und Lüfter sorgen neben zahlreichen Hochverfügbarkeitsmerkmalen dafür, dass der G8052 zu jeder Zeit für geschäftskritischen Datenverkehr verfügbar ist.

Scalability and performance:
Media access control (MAC) address learning with automatic updates
Static and LACP (IEEE 802.3ad) link aggregation
Broadcast/multicast storm control
IGMP snooping for limit flooding of IP multicast traffic
IGMP filtering to control multicast traffic for hosts participating in multicast groups
Configurable traffic distribution schemes over trunk links based on source or destination IP or MAC addresses, or both
Fast port forwarding for rapid STP convergence
Availability and redundancy:
IEEE 802.1D STP for providing L2 redundancy
IEEE 802.1s Multiple STP (MSTP) for topology optimization
IEEE 802.1w Rapid STP (RSTP) (provides rapid STP convergence for critical delay-sensitive traffic, such as voice or video)
Per-VLAN Rapid STP (PVRST) enhancements
Layer 2 Trunk Failover to support active/standby configurations of network adapter teaming on servers
Hot Links provides basic link redundancy with fast recovery for network topologies that require Spanning Tree to be turned off
VLAN support:
Port-based and protocol-based VLANs
Up to 4094 VLANs supported per switch (2048 active VLANs), with VLAN numbers 1 - 4094
802.1Q VLAN tagging support on all ports
Ingress VLAN tagging support to tunnel packets through a public domain without altering the original 802.1Q tagging information
802.1x with dynamic guest VLAN assignment
Private VLANs support as defined in RFC 5517
OpenFlow 1.0 and 1.3.1 support
Virtualization:
Virtual link aggregation groups (vLAGs)
Two switches (vLAG peers) act as a single virtual entity for a multi-port aggregation
vLAG Peer Gateway for improved usage of the inter-switch link between the vLAG peers
Two-tier vLAGs with VRRP enables active/active VRRP support to reduce routing latency
Supports 802.1Qbg Edge Virtual Bridging (EVB) which is an emerging IEEE standard for allowing networks to become virtual machine (VM)-aware:
Virtual Ethernet Bridging (VEB) and Virtual Ethernet Port Aggregator (VEPA) are mechanisms for switching between VMs on the same hypervisor.
Edge Control Protocol (ECP) is a transport protocol that operates between two peers over an IEEE 802 LAN providing reliable, in-order delivery of upper layer protocol data units.
Virtual Station Interface (VSI) Discovery and Configuration Protocol (VDP) allows centralized configuration of network policies that persist with the VM, independent of its location.
EVB Type-Length-Value (TLV) is used to discover and configure VEPA, ECP, and VDP.
VMready support:
Up to 1,024 virtual entities (VEs)
Automatic VE discovery
Up to 1,024 local or distributed VM groups for VEs
NMotion® feature for automatic network configuration migration

Traffic shaping and re-marking based on defined policies
Eight priority queues per port for processing qualified traffic
