Lenovo RackSwitch G7028

Brand: Lenovo
Model Number: G7028

Introduction

The Lenovo RackSwitch™ G7028 is an inexpensive, 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 for customer solutions that require greater I/O bandwidth. The RackSwitch G7028 is an ideal solution for data center customers who need an economical 1 Gb and 10 Gb connectivity solution.

The RackSwitch G7028 (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 24x 10/100/1000BASE-T RJ-45 ports and four 10 Gigabit Ethernet SFP+ ports standard, while typically using only 45 watts of power. The RackSwitch G7028 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.

 

Key features

The RackSwitch G7028 switch is considered particularly suited for the following customers:

  • Customers who want to use GbE in their infrastructure (servers and networking)
  • Customers who are implementing a virtualized environment and require multiple GbE ports
  • Customers who require investment protection for 10 GbE ports
  • Customers who want to reduce total cost of ownership (TCO) and improve performance while maintaining high levels of availability and security
  • Customers who want to avoid or minimize oversubscription, which can result in congestion and loss of performance
  • Customers who want to implement a converged infrastructure with NAS or iSCSI

The G7028 switch offers the following key features and benefits:

  • Increases network performance

    The RackSwitch G7028 provides up to 128 Gbps of switching throughput, supports four SFP+ 10 Gb uplink ports for zero oversubscription, and has a port to port latency of 3.3 microseconds.

  • Lower power and exceptional cooling

    The RackSwitch G7028 typically uses only 45 W of power. Unlike side-cooled switches, which can cause heat recirculation and reliability concerns, the RackSwitch G7028 switch's rear-to-front cooling design reduces data center air conditioning costs by matching airflow to the server’s configuration in the rack.

  • Fault tolerance

    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.

  • Seamless interoperability

    RackSwitch switches interoperate seamlessly with other vendors' upstream switches.
