Cisco UCS M4308 Modular Chassis Data Sheet

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.

The Cisco UCS M142 Compute Cartridge is the first cartridge supported by the Cisco UCS M4308 Modular Chassis.

Overview

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:

●   2RU chassis: 3.5 x 30.5 x 17.5 in. (H x L x W)

●   Up to eight Cisco UCS M142 Compute Cartridges

●   Redundant 1400W power supplies

●   Cisco 12G modular RAID controller with 2-GB flash-backed write cache (FBWC)

●   2 x 40-Gbps uplinks

●   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.
