The Lenovo RackSwitch G7052 is a low-cost, entry-level Layer 2 1/10 Gb Ethernet switch that is designed for the data center. Data center customers continue to deploy applications by using 1 GbE networking switches while 10 GbE continues to grow upstream in the network as clients require greater I/O bandwidth. The RackSwitch G7052 is an ideal solution for data center customers who need an economical 1 Gb and 10 Gb connectivity solution.
The RackSwitch G7052 (see the following figure) is a top-of-rack data center switch that delivers excellent non-blocking, wire speed performance at an attractive price point. It supports 48x 10/100/1000BASE-T RJ-45 ports and four 10 Gigabit Ethernet SFP+ ports standard, while typically using only 76 watts of power. The RackSwitch G7052 is also designed with rear-to-front airflow, which allows for flexible mounting of the switch in a rack cabinet and provides convenient cable management and significant savings in cooling costs.
The RackSwitch G7052 switch is considered particularly suited for the following customers:
The switch offers the following key features and benefits:
Increases network performance
The RackSwitch G7052 provides up to 176 Gbps of switching throughput, supports four SFP+ 10 Gb uplink ports, and has a port to port latency of 3.3 microseconds.
Lower power and exceptional cooling
The RackSwitch G7052 typically uses only 76 W of power. Unlike side-cooled switches, which can cause heat recirculation and reliability concerns, the RackSwitch G7052 switch’s rear-to-front cooling design reduces data center air conditioning costs by matching airflow to the server’s configuration in the rack.
These switches learn alternative paths automatically and perform faster convergence if there is a link, switch, or power failure. The switch uses technologies, such as Virtual Link Aggregation, L2 trunk failover, and Hot Links.
RackSwitch switches interoperate seamlessly with other vendors’ upstream switches.
Additional Power Supply
The RackSwitch G7052 supports an optional external redundant power supply with the Lenovo RackSwitch G7000 Redundant Power Supply (RPS) option.
