N20-B6740-2 Cisco UCS B440 M1 Blade Server w/o CPU, memory, HDD, mezzanine
Cisco N20-B6740-2 UCS B440 M1 High-Performance Blade Server
Scalable 4-Socket Full-Width Blade for Mission-Critical Enterprise Workloads
The Cisco Systems UCS B440 M1 Blade Server (N20-B6740-2) is a powerful, enterprise-class, full-width blade server engineered for compute-intensive and memory-heavy workloads. Designed for deployment within the Cisco UCS 5108 Blade Server Chassis, this 4-socket server supports Intel Xeon 7500 Series processors and delivers exceptional scalability for large virtualized environments, in-memory databases, and mission-critical enterprise applications.
With support for up to four CPUs and 32 DIMM slots of DDR3 ECC memory, the UCS B440 M1 enables high consolidation ratios and outstanding performance for data-hungry workloads. Two mezzanine expansion slots provide flexible I/O options, allowing integration of Cisco VICs or converged network adapters for high-bandwidth unified fabric connectivity.
The N20-B6740-2 part number represents a base configuration, giving organizations complete freedom to customize processors, memory, storage, and network adapters to match exact workload requirements. Managed centrally through Cisco UCS Manager, the B440 M1 simplifies operations with policy-based provisioning, unified management, and consistent performance across the data center.

FAQs:
Q1. Does this server include any CPUs or RAM?
No, the N20-B6740-2 is a "base" unit. You must install compatible Intel Xeon 7500 processors and DDR3 memory separately to make the unit functional.
Q2. How many slots does this blade occupy in the UCS 5108 chassis?
As a full-width blade, the B440 M1 occupies two horizontal slots. A single 5108 chassis can hold up to four of these servers.
Q3. What kind of mezzanine cards should I use?
For optimal performance and integration with the UCS fabric, Cisco Virtual Interface Cards (VICs) are recommended, though third-party Converged Network Adapters (CNAs) are also supported.
Q4. Can I mix this blade with B200 M2/M3 blades in the same chassis?
Yes. The UCS 5108 chassis is designed to host a mix of full-width and half-width blades simultaneously, provided there is enough power and cooling.
Q5. What is the maximum memory capacity?
While dependent on the specific DIMM density used, the 32-slot architecture was designed to support up to 512GB of RAM using 16GB modules.
