The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Modular, Dense, and Power-Efficient Computing Platform for Cloud-Scale Applications
Cisco UCS® M-Series Modular Servers are designed to meet the high-performance demands of massively parallelized, predominantly single-threaded applications. The innovative architecture of the Cisco UCS M-Series combines Cisco® Virtual Interface Card (VIC) technology and server fabric management with widely deployed x86 computing elements for a cost-effective, scalable platform. The Cisco UCS M4308 Modular Chassis is one of the main elements of the Cisco UCS M-Series Modular Servers.
The Cisco UCS M4308 Modular Chassis (Figure 1) extends the capabilities of the Cisco Unified Computing System™ (Cisco UCS) portfolio to a high-density 2RU form-factor chassis with up to eight front-access slots that accommodates up to eight single-wide cartridges.
The chassis architecture accommodates computing cartridges as well as other specialized cartridges. The rear of the chassis supports four SSDs that are connected to an internal removable RAID controller. Storage capacity and connectivity are distributed to the pluggable computing cartridges using Cisco’s third-generation VIC. Network I/O is provided by two 40-Gbps QSFP ports that aggregate all computing cartridge I/O and management traffic into a single connection for cable consolidation and efficiency. An upstream VNTag-capable top-of-rack switch is required for the total solution and is available at launch with the Cisco UCS 6200 Series Fabric Interconnects.
One of the main components of the Cisco UCS M4308 Modular Chassis is Cisco’s next-generation VIC. The VIC provides the connectivity between the compute cartridges, the shared peripherals, and the Fabric Interconnects. The unique technology of the VIC enables a high level of server disaggregation and exceptional centralization of components across multiple servers: components that were previously captive and redundant in each and every physical server. The Cisco UCS M4308 chassis houses eight Compute Cartridges, each with two independent servers, as well as the centralized resources, which are shared across the system components.
The Cisco UCS M4308 Modular Chassis consists of the following:
●Up to 4 SSDs: Choice of SAS or SATA drives with capacities ranging from 240 GB to 1.6 TB per disk
The Cisco UCS M4308 chassis is physically cabled to the Cisco UCS 6200 Series Fabric Interconnects. Fabric interconnects provide the management and communication backbone for the chassis and the installed compute cartridges. Up to 20 Cisco UCS M4308 chassis and the associated cartridges can be attached to a pair of Fabric Interconnects and managed as part of a single domain. Centralized unified management is provided by Cisco UCS Manager, which comes embedded on the Fabric Interconnects at no additional charge.
Cisco UCS M4308 Chassis Features and Benefits
Table 1 summarizes the features and benefits of the Cisco UCS M4308 Modular Chassis.
Table 1.Features and Benefits
Unique architecture accommodating 16 servers in a 2RU footprint and up to 320 servers (1280 cores) in a single data center rack
The industry-leading server density offered by the Cisco UCS M-Series results in significant cost savings for data center customers deploying a large number of smaller servers to host highly parallelized workloads.
Unified embedded management provided by the proven Cisco UCS Manager, integrating servers, network, and storage
Single pane of glass to provision and manage all components in the rack without the need to switch from one console to another.
Policy-based provisioning and management enabled by Cisco UCS service profiles
Service Profiles augmented with the newly unleashed Storage Profiles significantly enable the dynamic slicing of centralized resources and help ensure the quality of service (QoS) for the deployed workloads.
Modular chassis with hot-pluggable components
The Cisco UCS M-Series enhances serviceability by providing easy tool-less replacement options for almost all the field-replaceable units (FRUs), thereby minimizing or eliminating downtime.
Reduced power consumption per server
The Cisco UCS M-Series uses the latest low-power-consuming CPUs to deliver optimized performance per watt.
