Did you know?

The RackSwitch G8052 is designed with line-rate throughput and low latency of less than 2 microseconds.

The RackSwitch G8052 includes redundant and hot-swappable power supplies and fans.

The RackSwitch G8052 is designed specifically for the data center environment with server-matching airflow, high-availability hardware and software features, rich Layer 2/3 functionality, and ease of management.

The RackSwitch G8052 is SDN ready with its OpenFlow support. With OpenFlow, you can easily create user-controlled virtual networks, optimize performance dynamically, and minimize complexity when it is used with an OpenFlow controller.

The RackSwitch G8052 is also cloud ready with its VMready® switch-resident software that helps reduce the complexity of configuring and managing virtual machines throughout the network, making it VM-aware.

The RackSwitch G8052 supports stacking for up to eight switches by using a single switch image and configuration file that shares one IP address and one management interface for simplified management.

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

Key features

The RackSwitch G8052 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 wanting to simplify management by stacking up to eight switches and managing them as a single entity
  • Customers who want to implement a converged infrastructure with NAS or iSCSI

The switch offers the following key features and benefits:

  • High performance

    The RackSwitch G8052 provides up to 176 Gbps throughput and supports four SFP+ 10 Gb uplink ports for a low oversubscription ratio and a low latency of 1.8 microseconds.

  • Lower power and better cooling

    The RackSwitch G8052 typically uses only 130 W of power, a fraction of the power consumption of most competitive offerings. The G8052’s rear-to-front or front-to-rear cooling design reduces data center air conditioning costs by matching airflow to the server’s configuration in the rack. Variable speed fans assist in automatically reducing power usage.

  • VM-aware network virtualization

    VMready software on the switch simplifies configuration and improves security in virtualized environments. VMready automatically detects VM movement between physical servers and instantly reconfigures each VM’s network policies across VLANs to keep the network up and running without interrupting traffic or affecting performance. VMready works with all leading hypervisors, such as VMware, Citrix Xen, Red Hat KVM, and Microsoft Hyper-V.

  • Layer 3 functionality

    The RackSwitch G8052 includes Layer 3 functionality, which provides security and performance benefits and the full range of Layer 3 static and dynamic routing protocols, including Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP) for enterprise customers at no extra cost.

  • Stacking support

    Supports up to eight switches that use a single switch image and configuration file that shares one IP address and one management interface for simplified management.

  • Fault tolerance

    These switches learn alternative routes automatically and perform faster convergence if there is a link, switch, or power failure. The switch uses proven technologies, such as L2 trunk failover, advanced VLAN-based failover, VRRP, Hot Links, IGMP V3 snooping, and OSPF.

  • OpenFlow enabled

    The RackSwitch G8052 offers benefits of OpenFlow. OpenFlow is the open application programming interface (API) that enables the network administrator to easily configure and manage virtual networks that control traffic on a “per-flow” basis. It creates multiple independent virtual networks and related policies without dealing with the complexities of the underlying physical network and protocols. The G8052 can be used with any industry compliant OpenFlow controller.

  • Seamless interoperability

    RackSwitch switches interoperate seamlessly with other vendors' upstream switches.

  • Transparent networking capability

    With a simple configuration change to Easy Connect Mode, the RackSwitch G8052 becomes a transparent network device that is invisible to the core and eliminates network administration concerns of Spanning Tree Protocol configuration and interoperability and VLAN assignments and avoids any possible loops. By emulating a host NIC to the data center core, it accelerates the provisioning of VMs by eliminating the need to configure the typical access switch parameters.

Rack installation

The G8052 switch includes a 2-post rack mount kit.

For 4-post rack installations, the G8052 switch supports the optional adjustable 19-inch, 4-post rail kit and the air inlet duct (optional for the 4-post rail kit; supported only with the models with rear to front airflow).

When the G8052 switch (front to rear airflow) is installed in the Intelligent Cluster Rack (Machine Type 1410) or Enterprise Rack (Machine Type 9363) as a part of a NeXtScale System solution, the recessed 19-inch 4-post rail kit and the switch seal kit are required.  The seal kit includes enough switch seals for six switches.

The following table lists rack installation options for the G8052 switches with rear to front and front to rear airflow.

Warranty and maintenance

The RackSwitch G8052 comes with a 3-year Customer Replaceable Unit (CRU) hardware limited warranty with 9x5 Next Business Day (NBD) Parts Delivered and includes a 3-year software license, which provides entitlement to upgrades over that period. The options that are installed in the switch assume the switch’s base warranty and any Lenovo warranty service upgrade for the switch.

Some countries might have different warranty terms and conditions than the standard warranty. This is due to local business practices or laws in the specific country. Local service teams can assist in explaining country-specific terms when needed. Examples of country-specific warranty terms are second or longer business day parts delivery or parts-only base warranty.

If warranty terms and conditions include onsite labor for repair or replacement of parts, Lenovo will dispatch a service technician to the customer site to perform the replacement. Onsite labor under base warranty is limited to labor for replacement of parts that have been determined to be field-replaceable units (FRUs). Parts that are determined to be customer-replaceable units (CRUs) do not include onsite labor under base warranty.

If warranty terms include parts-only base warranty, Lenovo is responsible for delivering only replacement parts that are under base warranty (including FRUs) that will be sent to a requested location for self-service. Parts-only service does not include a service technician being dispatched onsite. Parts must be changed at customer’s own cost and labor and defective parts must be returned following the instructions supplied with the spares parts.

Also available are Lenovo Services warranty maintenance upgrades and post-warranty maintenance agreements, with a well-defined scope of services, including service hours, response time, term of service, and service agreement terms and conditions.

Lenovo warranty service upgrade offerings are country-specific. Not all warranty service upgrades are available in every country. For information about Lenovo warranty service upgrade offerings that are available in your country or area, refer to the following resources:

In general, the following Lenovo warranty service upgrades are available:

  • Warranty and maintenance service upgrades:
    • 3, 4, or 5 years of warranty service coverage
    • 1-year or 2-year post-warranty extensions
    • Foundation Service: 9x5 service coverage with next business day onsite response
    • Essential Service: 24x7 service coverage with 4-hour onsite response or 24-hour committed repair (available only in select countries)
    • Advanced Service: 24x7 service coverage with 2-hour onsite response or 6-hour committed repair (available only in select countries)
  • Premier Support

    Premier Support service offers direct access to Lenovo’s most advanced technicians for faster troubleshooting with single point of contact for end-to-end problem resolution and collaborative third-party software support.

  • Basic Hardware Installation Services

    Lenovo experts can seamlessly manage the physical installation of your server, storage, or networking hardware. Working at a time convenient for you (business hours or off shift), the technician will unpack and inspect the systems on your site, install options, mount in a rack cabinet, connect to power and network, check and update firmware to the latest levels, verify operation, and dispose of the packaging, allowing your team to focus on other priorities.
