The Building Block of Scale and Flexibility

Gain easy scalability to meet the needs of your applications without overprovisioning. The M4308 Modular Chassis is the building block, the unit of scale, for the new UCS M-Series Modular Server platform. It delivers the benefits of this radically different architecture to Cisco UCS M-Series Compute Cartridges.

Features and Capabilities

The Cisco UCS M4308 Modular Chassis platform delivers a unique composable infrastructure to meet the needs of today's highly parallelized and distributed applications.

With this design, Cisco can abstract server subsystems completely into the infrastructure, and completely off the computing nodes. The disaggregated subcomponents are:

  • Power
  • Cooling
  • I/O
  • Disk drives
  • Management

With the separation of components in the M4308, users can decouple the lifecycles of the subsystems. Now every subcomponent can be refreshed independently, on its own lifecycle schedule, without provoking a major platform refresh.

This independent-resource strategy enables Cisco to optimize and more efficiently deliver infrastructure to meet the specific needs of your applications.

You no longer need costly and time-consuming professional services just to expand your computing capacity. With the M4308 and the M-Series solution, scaling is now easy and affordable.

The M4308 design also allows for smaller increments of scale, so your applications get the number of computing nodes they require to achieve the desired performance and availability. No more overprovisioning. No more wasted resources. Everything is under a single management tool for easy scale and management transparency.

With this groundbreaking design, the Cisco UCS M-Series provides a highly dense, modular, and power-efficient platform designed to meet the needs of parallelized workloads. It provides for optimal:

  • Performance and watt usage
  • Computing capacity and rack unit (RU) space

The Cisco UCS M-Series Modular Server system features a new 2-RU chassis built on the innovative foundation of Cisco Virtual Interface Card (VIC) technology called System Link. All M4308 chassis connect to a pair of Cisco UCS Fabric Interconnects with Cisco UCS Manager, providing easy, fast scalability with industry-leading Cisco UCS management.

The award-winning Cisco UCS Manager provides management for the M-Series with consistency and simplicity in device management. Cisco UCS Manager is a model-based, automated tool for element management that allows for easy integration with higher-level tools using our open XML API.
