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.

Did you know?

The RackSwitch G7028 is designed with non-blocking, line-rate throughput.

The RackSwitch G7028 supports an optional external redundant power supply with the Lenovo RackSwitch G7000 Redundant Power Supply option.

The RackSwitch G7028 is designed specifically for the data center environment with server-matching airflow, cost-effective Layer 2 switching and ease of configuration management.

Networking Operating System software features deliver seamless, standards-based integration into upstream switches.

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.

The RackSwitch G7028 supports an optional external redundant power supply with the Lenovo RackSwitch G7000 Redundant Power Supply (RPS) option that is shown in the following figure.

Lenovo RackSwitch G7000 Redundant Power Supply

Figure 2. Lenovo RackSwitch G7000 Redundant Power Supply

The G7000 RPS option has the following features:

  • Form factor: 1U rack mount
  • Power connections: Four DC connections in the rear of the rack to connect to the G7028 and G7052 switches; one AC inlet connector to connect to the power source (rack PDU or wall connector)
  • Airflow: Rear-to-front cooling
  • Power: Approximately 55 - 276 W, which varies depending upon operating conditions and number and types of switches connected
  • Rack installation: Generic rack-mount kit (2-post); optional flexible 4-post mounting option for the server rack and the communications rack
  • LEDs: System LEDs to indicate status

Transceivers and cables

With the flexibility of the G7028 switch, customers can choose the following connectivity technologies:

  • For 1 GbE links, customers can use RJ-45 UTP cables up to 100 meters. Customers that need longer distances can use the 1000BASE-SX transceivers in the SFP/SFP+ ports, which can drive distances up to 220 meters with 62.5 µ multi-mode fiber (OM1) and up to 550 meters with 50 µ multi-mode fiber (OM2), or the 1000BASE-LX transceivers that support distances up to 10 kilometers with single-mode fiber (1310 nm).
  • For 10 GbE links (supported on SFP+ ports), customers can use direct-attached copper (DAC) SFP+ cables for in-rack cabling for distances up to 7 meters or SFP+ active optical cables (AOCs) for distances up to 20 meters. These cables have SFP+ connectors on each end, and they do not need separate transceivers. For distances up to 30 meters, the 10GBASE-T SFP+ transceiver can be used with Category 6a or 7 RJ-45 UTP cables.

    For longer distances, the 10GBASE-SR transceiver can support distances up to 300 meters over OM3 multimode fiber or up to 400 meters over OM4 multimode fiber. The 10GBASE-LR transceivers can support distances up to 10 kilometers on single mode fiber.

The following optional warranty and maintenance upgrades are available for the RackSwitch G7028 through Lenovo service upgrade offerings:

  • Warranty service upgrades (3, 4, or 5 years):
    • 24x7 onsite repair with 2-hour target response time
    • 24x7 onsite repair with 4-hour target response time
    • 9x5 onsite repair with 4-hour target response time
  • Maintenance (post-warranty) service offerings (1 or 2 years):
    • 24x7 onsite repair with 2-hour target response time
    • 24x7 onsite repair with 4-hour target response time
    • 9x5 onsite repair with 4-hour target response time
    • 9x5 onsite repair with next business day target response time
