Key featuresThe Flex System Enterprise Chassis is a simple, integrated infrastructure platform that supports a mix ofcompute, storage, and networking resources to meet the demands of your applications. The solution iseasily scalable with the addition of another chassis with the required nodes. With Lenovo XClarityAdministrator, multiple chassis can be monitored from a single screen. This flexible 14 node, 10U chassisis designed for a simple deployment now and to scale to meet your needs in the future.Flexibility and efficiencyThe 14 bays in the chassis allow the installation of compute or management nodes, with networkingmodules in the rear. A single chassis or a group of chassis can be fully customized to the specific needs ofthe computing environment. IT can meet the needs of the business using a single system across multipleoperating environments.The system monitors and manages power usage on all major chassis components so you have totalcontrol over power consumption. Available power supply options are AC and -48V DC. AC power optionscan be configurable in either a single or three-phase power domain. The chassis supports N+N or N+1redundant power supplies and an entirely passive mid-plane to meet your reliability needs. The powersupplies are 80 PLUS Platinum-certified indicating high energy efficiency. The chassis design alsooptimizes cooling with cooling zones within the chassis. The system manages the fan modules based onnode configuration within the chassis. So, the system can increase the speed of certain fan modules tocool potential hot spots, and use lower speeds for other fan modules where appropriate.Easily scalable with simple administrationBecause the Flex System Enterprise Chassis is an all-in-one solution, it is designed for growth from asingle chassis to many. Adding compute, or networking capability is as simple as adding additional nodesor modules. Compute nodes and I/O modules connect to a midplane and are designed to be inserted orremoved while the chassis is running. The use of the midplane means that the compute nodes and I/Omodules do not need their own power cables and do not need network cables or transceivers to connectto each other within the chassis. These features make it easy to add or replace compute nodes and getthem operational quickly.The simple, highly integrated management system allows you to use the Chassis Management Modulesintegrated into each chassis to administer a single chassis, and the new Lenovo XClarity Administratoroffers agent-free hardware management for compute nodes and networking.Designed for multiple generations of technologyThe Flex System Enterprise Chassis is designed to be the foundation of your IT infrastructure now and intothe future. Compute performance requirements are always on the rise and networking demands continueto grow with rising bandwidth needs and a shrinking tolerance for latency. The chassis is designed toscale to meet the needs of your future workloads, offering the flexibility to support current and futureinnovations in compute, storage, and networking technology.Locations of key components and connectorsFlex System Enterprise Chassis 2
