Enterprise ChassisLenovo Flex System Carrier-Grade ChassisProduct Guide

Flex System is the next generation of blade technology with more performance and bandwidth and far more capability to consolidate and virtualize than previous systems.Introducing the Lenovo Flex System Carrier-Grade Chassis, a new version of the Flex System chassis that is de-signed for the telecommunications industry where tolerance of harsher environments is required. This Carrier- Grade Chassis is designed to NEBS level 3 and ETSI certification levels and for operation within Earthquake Zone 4 areas. The chassis also includes dust filters and -48V DC power operation, as required for many Central Office telco environments.

Figure 1. Flex System Carrier-Grade Chassis

Did you know?The chassis is ASHRAE 4 compliant, meaning it allows normal operation in temperatures of up to 45 °C (113 °F), with temporary elevated temperature excursions of up to 55 °C (131 °F) for as long as 4 days. This is a key requirement for industries, such as the telecommunications industry where the harsher environments in central offices (COs) require IT equipment that operate on -48V DC power and can tolerate higher temperatures.

Key featuresSimilar to the Enterprise Chassis, the Flex System Carrier-Grade Chassis is a simple, integrated infrastructure platform that supports a mix of compute, storage, and networking resources to meet the demands of your appli-cations. The solution is easily scalable with the addition of another chassis with the required nodes. With Lenovo XClarity Administrator, multiple chassis can be monitored from a single window. This flexible 14 node, 10U chas-sis is designed for a simple deployment now and to scale to meet your needs in the future.

A single chassis or a group of chassis can be fully customized to the specific needs of the computing environment. IT can meet the needs of the business by using a single system across multiple operating environments.

The system monitors and manages power usage on all major chassis components so you have total control over power consumption. With -48V DC power supplies and N+N or N+1 redundancy, the chassis integrates into telco environments, such as those in central offices. The chassis design also optimizes cooling with cooling zones with-in the chassis. There is sufficient cooling throughout the chassis to allow normal operation in temperatures of up to 45 °C (113 °F), with temporary elevated temperature excursions of up to 55 °C (131 °F) for as long as 4 days.

The system manages the fan modules based on the node configuration within the chassis. Therefore, the system can increase the speed of certain fan modules to cool potential hot spots and use lower speeds for other fan modules where appropriate.

Easily scalable with simple administrationBecause the Carrier-Grade Chassis is an all-in-one solution, it is designed for growth from a single chassis to many. Adding compute or networking capability is as simple as adding nodes or modules. The simple, highly in-tegrated management system allows you to use the Chassis Management Modules that are integrated into each chassis to administer a single chassis, and the new Lenovo XClarity Administrator offers agent-free hardware management for compute nodes and networking.

95Y3309 is the part number for the base physical device, and it comes with 14 internal 10 GbE ports enabled (one to each compute node) and ten external 10 GbE ports enabled.49Y4798 (Upgrade 1) can be applied on the base switch when you take full advantage of four-port adapter cards installed in each compute node. This upgrade enables 14 additional internal ports, for a total of 28 ports. The upgrade also enables two 40 GbE external ports. This upgrade requires the base switch.88Y6037 (Upgrade 2) can be applied on top of the Upgrade 1 when you need more external bandwidth on the switch or if you need additional internal bandwidth to the compute nodes with the six-port capable adapter cards. The upgrade will enable the remaining four external 10 GbE external ports, plus 14 additional internal 10 GbE ports, for a total of 42 internal ports (three to each compute node).

Flexible port mapping: With Networking OS version 7.8 or later clients have more flexibility in assigning ports that they have licensed on the EN4093R which can help eliminate or postpone the need to purchase upgrades. While the base model and upgrades still activate specific ports, flexible port mapping provides clients with the capability of reassigning ports as needed by moving internal and external 10 GbE ports, or trading off four 10 GbE ports for the use of an external 40 GbE port. This is very valuable when you consider the flexibility with the base license and with Upgrade 1.

Note: Flexible port mapping is not available in Stacking mode.

With flexible port mapping, clients have licenses for a specific number of ports:

• Convergence and lower acquisition and operational costsOne of the key trends that is driving the transformation of the data center is converging to a simplified networking infrastructure, which collapses Ethernet and Fibre Channel at the server and the edge of the network while maintaining connectivity upstream to existing LANs and SANs. The CN4093 Converged Switch supports multiple protocols, including Ethernet, Fibre Channel, iSCSI, and FCoE; Omni Ports give customers the flexibility to choose between 10 Gb Ethernet external connections to the top-of-rack switch and 4/8 Gb Fibre Channel for flexible and scalable access to FC storage.

• Increased performanceWith the growth of virtualization and the evolution of cloud, many of today’s applications require low latency and high bandwidth performance. The CN4093 is the embedded 10 GbE switch for a Flex System chassis to support sub-microsecond latency and up to 1.28 Tbps, while also delivering full line rate performance on Ethernet ports, which makes it ideal for managing dynamic workloads across the network. In addition, this switch provides a rich Layer 2 and Layer 3 feature set that is ideal for many of today’s data centers. It also offers industry-leading external bandwidth by being the integrated switch to support 40 GbE external ports.

• Pay-as-you-grow investment protection and lower total cost of ownershipThe CN4093’s flexible port mapping allows customers to buy only the ports that are needed and when need-ed. The base switch configuration includes 22x 10 GbE port licenses that can be assigned to internal connec-tions and external SFP+, Omni Ports, or 40 GbE QSFP+ ports (by using four 10 GbE licenses per one 40 GbE port). Customers then have the flexibility of turning on more internal 10 GbE connections and more external ports when needed by using Features on Demand licensing capabilities that provide pay-as-you-grow scal-ability without the need for more hardware.

• Cloud ready, optimized network virtualization with virtual NICs

With most IT organizations implementing virtualization, there is an increased need to reduce the cost and complexity of their environments. Lenovo is helping to address these requirements by removing multiple physical I/O ports. Virtual Fabric provides a way for companies to carve up 10 GbE ports into virtual NICs (vNICs) to meet those requirements with Intel processor-based compute nodes.

To help deliver maximum performance per vNIC and to provide higher availability and security with isolation between vNICs, the switch uses the capabilities of its Networking Operating System. For large-scale virtual-ization, the Flex System solution can support up to 48 vNICs by using a pair of CN4058S 10Gb Virtual Fabric

Adapters in each compute node and four CN4093 10Gb Converged Scalable Switches in the chassis.

The CN4093 offers the benefits of next-generation vNIC, which is Unified Fabric Port (UFP). UFP is an ad-vanced, cost-effective solution that provides a flexible way for clients to allocate, reallocate, and adjust band-width to meet their ever-changing data center requirements.
