Product Overview

The form-factor-agnostic Cisco Unified Computing System (Cisco UCS) combines Cisco UCS C-Series Rack Servers and B-Series Blade Servers with networking and storage access in a single converged system that simplifies management and delivers greater cost efficiency and agility with increased visibility and control. The latest expansion of the Cisco UCS portfolio includes the new Cisco UCS C24 M3 Rack Server. This new server increases compute density through more cores and cache balanced with adequate memory capacity, abundant internal disk drives and faster I/O. Together these server improvements and complementary Cisco UCS advancements deliver the combination of features and cost efficiency required to support IT’s diverse server needs.

The Cisco UCS C24 M3 Rack Server (Figure 1) is designed for both outstanding economics and internal expandability. The Cisco C24 M3 Rack Server targets entry level virtualization, IT and web infrastructure as well as storage-intensive infrastructure workloads from big data and small to medium databases to file serving and windows storage servers. Building on the success of the Cisco UCS C-Series Rack Servers, the Cisco UCS C24 M3 server and the Cisco UCS Virtual Interface Card 1225 (VIC 1225) extend the capabilities of the Cisco UCS portfolio in a 2RU form factor with the Intel® Xeon® processor E5-2400 product family, which delivers an optimal combination of performance, flexibility, and efficiency gains. In addition, the Cisco UCS C24 M3 offers up to 12 DIMM slots, up to 12, 16 or 24 disk drives, 5 PCI express (PCIe) slots, and two 1 Gigabit Ethernet LAN-on-motherboard (LOM) ports to provide an exceptional internal storage capacity and price-to-performance ratio.

The Cisco UCS C24 M3 server interfaces with Cisco UCS using another Cisco® innovation: the Cisco UCS Virtual Interface Card 1225. The Cisco UCS Virtual Interface Card 1225 is a virtualization-optimized Fibre Channel over Ethernet (FCoE) PCIe 2.0 x8 10-Gbps adapter designed for use with Cisco UCS C-Series Rack Servers. The Virtual Interface Card 1225 is a dual-port 10 Gigabit Ethernet PCIe adapter that can support up to 18 PCIe standards-compliant virtual interfaces, which can be dynamically configured so that both their interface type (network interface card [NIC] or host bus adapter [HBA]) and identity (MAC address and worldwide name [WWN]) are established using just-in-time provisioning. In addition, the Cisco UCS VIC 1225 can support network interface virtualization and Cisco Data Center Virtual Machine Fabric Extender (VM-FEX) technology.

Not all storage-intensive workloads are alike, and the Cisco UCS C24 M3 server’s disk configuration delivers balanced performance and expandability to best meet individual workload requirements. With up to 12, 16 or 24 internal drives, the Cisco UCS C24 M3 optionally offers 10,000- and 15,000-RPM SAS drives to deliver a high number of I/O operations per second (IOPS) for transactional workloads such as database management systems. In addition, high-capacity SATA drives provide an economical, large-capacity solution.

The Cisco UCS C24 M3 further increases performance and customer choice over many types of storage-intensive applications such as:

   IT and Web Infrastructure

   Big data


   Storage server

   Entry-level virtualization

   Small to Medium databases

   File Server

   Storage-intensive infrastructure

Cisco UCS Servers Change the Economics of the Data Center

Cisco continues to lead in data center innovation with infrastructure as a service (IaaS), bare metal, virtualized servers, and cloud computing with the introduction of new building blocks such as the C24 M3 server for Cisco UCS that extend the system’s exceptional simplicity, agility, and efficiency (Figure 2). The C24 M3 server also continues Cisco’s commitment to delivering uniquely differentiated value, fabric integration, and ease of management that is exceptional in the marketplace.

Figure 2.      Cisco UCS Components

For example, Cisco innovations, such as the form-factor-agnostic Cisco UCS Manager software, allows administrators to create a software model of a desired server (using Cisco service profiles and templates) and then instantiate that server and its I/O connectivity by associating a model with physical resources. This stateless approach contrasts with the traditional method of configuring each system resource manually, one at a time, through individual element managers. Unlike vendors of traditional systems, Cisco uses a unified management model with service profiles that can be moved easily between any Cisco UCS servers, whether blade server or rack server, in a Cisco UCS Manager domain.

Other Cisco UCS building blocks include enhanced server I/O options and expanded Cisco UCS fabric interconnects that extend scalability, investment protection, and management simplicity for both rack and blade systems. Here are a few examples of investment protection:

   Fabric extenders can be upgraded using the same fabric interconnects and the same Cisco UCS VIC 1225.

   Fabric interconnect hardware can be upgraded independently of fabric extenders and rack servers.

In addition, Cisco continues to innovate in nearly all hardware and software components of Cisco UCS, helping ensure that more powerful rack servers have adequate I/O bandwidth, management scalability, and investment protection both now and in the future.

The Cisco UCS C24 M3 is also part of a larger family of rack servers: the Cisco UCS C-Series Rack Servers. Designed to operate both in standalone environments and as part of Cisco UCS, all Cisco UCS C-Series servers complement and extend Cisco innovation, investment protection, and simplicity. Cisco UCS C-Series servers provide innovations such as a standards-based unified network fabric, Cisco Data Center VM-FEX virtualization support, Cisco UCS Manager software, Cisco fabric extender and fabric interconnect architectures, and Cisco Extended Memory Technology. With Cisco UCS C-Series innovations, Cisco UCS architectural advantages, software advances, continuous innovation, and unique rack and blade server designs, Cisco UCS is the first truly unified data center platform. In addition, Cisco UCS can transform IT departments through policy-based automation and deep integration with familiar systems management and orchestration tools.
