Lenovo Flex System Enterprise Chassis



IBM Flex System, a new category of computing and the next generation of Smarter Computing, is anchored by the IBM Flex System Enterprise Chassis. This platform offers intelligent workload deployment and management for maximum business agility. This chassis delivers high-speed performance complete with integrated servers, storage, and networking for multi-chassis management in datacenter compute environments. 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. While increased security and resiliency protect vital information and promote maximum uptime, the integrated, easy-to-use management system reduces setup time and complexity, providing a quicker path to ROI.

The IBM Flex System Enterprise Chassis is a rack-optimized, 10U modular design enclosure that holds up to 14 nodes. It features:

  • New high-efficiency 2500-watt power supplies.
  • New hot-swap, 80 mm and 40 mm redundant fans.
  • Support for all new x86 compute nodes.
  • A Chassis Management Module (CMM) that gives you control over the solutions at the chassis level, simplifying installation and management of your installation. A second management module is optional.
  • Support for up to four traditional fabrics using networking switches, storage switches, or pass-through devices. The chassis also supports up to four switches, scalable to eight logical switches, and support for protocols such as Ethernet, Fibre Channel, FCoE, ISCI, and InfiniBand.


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.
