Introduction

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. Flex System is anchored by the Flex System Enterprise Chassis which enables high-speed performance with integrated servers and networking. Furthermore, its flexible design can meet the needs of varying workloads with independently scalable IT resource pools for higher utilization and lower cost per workload.

The Flex System Enterprise Chassis is shown in Figure 1.

Did you know?

In addition to the Flex System Enterprise Chassis, Lenovo also offers the Carrier-Grade Chassis for installations requiring tolerance to higher temperatures or for use in environments without filtered air. For information about the Carrier-Grade Chassis, see https://lenovopress.com/tips1285.

Key features

The Flex System Enterprise Chassis is a simple, integrated infrastructure platform that supports a mix of compute, storage, and networking resources to meet the demands of your applications. 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 screen. This flexible 14 node, 10U chassis is designed for a simple deployment now and to scale to meet your needs in the future.

Flexibility and efficiency

The 14 bays in the chassis allow the installation of compute or management nodes, with networking modules in the rear. 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 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. Available power supply options are AC and -48V DC. AC power options can be configurable in either a single or three-phase power domain. The chassis supports N+N or N+1 redundant power supplies and an entirely passive mid-plane to meet your reliability needs. The power supplies are 80 PLUS Platinum-certified indicating high energy efficiency. The chassis design also optimizes cooling with cooling zones within the chassis. The system manages the fan modules based on node configuration within the chassis. So, 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 administration

Because the Flex System Enterprise 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 additional nodes or modules. Compute nodes and I/O modules connect to a midplane and are designed to be inserted or removed while the chassis is running. The use of the midplane means that the compute nodes and I/O modules do not need their own power cables and do not need network cables or transceivers to connect to each other within the chassis. These features make it easy to add or replace compute nodes and get them operational quickly.

The simple, highly integrated management system allows you to use the Chassis Management Modules 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.

Designed for multiple generations of technology

The Flex System Enterprise Chassis is designed to be the foundation of your IT infrastructure now and into the future. Compute performance requirements are always on the rise and networking demands continue to grow with rising bandwidth needs and a shrinking tolerance for latency. The chassis is designed to scale to meet the needs of your future workloads, offering the flexibility to support current and future innovations in compute, storage, and networking technology.

† The maximum number of compute nodes supported depends on a number of factors. See below.
** A single Flex System Manager appliance can manage up to 16 chassis

The actual number of compute nodes systems that can be powered on in a chassis depends on these factors:

  • The TDP power rating for the processors that are installed in the compute nodes (x86 servers)
  • The number of power supplies installed in the chassis
  • The capacity of the power supplies installed in the chassis (2100 W or 2500 W)
  • The power redundancy policy used in the chassis (N+1 or N+N)

For the x480 X6 or x880 X6, if two compute nodes are scaled together, then a maximum of 3 scaled complexes can be installed. For the x880 X6, if four compute nodes are scaled together, then a maximum of 1 scaled x880 X6 complexes can be installed. Other bays can be filled with other compute nodes.

The table in the Power Supplies section provides guidelines about what number of compute nodes can be powered on in the Enterprise Chassis, based on the type and number of power supplies installed.
