Cisco UCS® B480 M5 Blade Server

The Cisco UCS® B480 M5 Blade Server delivers market-leading performance, versatility, and density without compromise.

Product overview

The enterprise-class Cisco UCS® B480 M5 Blade Server delivers market-leading performance, versatility, and density without compromise for memory-intensive mission-critical enterprise applications and virtualized workloads, among others.

With the B480 M5, you can quickly deploy stateless physical and virtual workloads with the programmability that Cisco UCS Manager and Cisco® SingleConnect technology enable. Customers gain support for Intel® Xeon® scalable processors, higher density 256G DDR4 DIMMs, new second-generation Intel® Xeon® Scalable processors, and the new Intel® Optane DC Persistent Memory. Additionally, these B480 M5 servers offer up to 12 terabytes (TB) of DDR4 memory or 18 TB using 24x256G DDR4 DIMMs and 24x512G Intel® Optane DC Persistent Memory; four SAS, SATA, and NVMe drives; M.2 storage; up to four GPUs and 160 Gigabit Ethernet connectivity for I/O throughput, all leading to exceptional performance, flexibility, and I/O throughput to run your most demanding applications.

The B480 M5 is a full-width blade server supported by the Cisco UCS 5108 Blade Server Chassis. The 5108 chassis and the Cisco B-Series Blade Servers provide inherent architectural advantages:

      Through Cisco UCS, gives you the architectural advantage of not having to power, cool, manage, and purchase excess switches (management, storage, and networking), Host Bus Adapters (HBAs), and Network Interface Cards (NICS) in each blade chassis

      Reduces the Total Cost of Ownership (TCO) by removing management modules from the chassis, making the chassis stateless

      Provides a single, highly available Cisco Unified Computing System (Cisco UCS) management domain for all system chassis and rack servers, reducing administrative tasks

Exceptional expandability

The Cisco UCS B480 M5 Blade Server delivers flexibility, density, and expandability in a 4-socket, full-width form factor for enterprise and mission-critical applications. It offers:

      Four new second-generation Intel® Xeon® scalable CPUs (up to 28 cores per socket)

      Four existing Intel® Xeon® Scalable CPUs (up to 28 cores per socket)

      Support for higher density DDR4 memory, from 6 TB (128G DDR4 DIMMs) to 12 TB (256G DDR4 DIMMs)

      Memory speeds increase from 2666 MHz to 2933 MHz

      Intel Optane DC Persistent Memory Modules (DCPMM) – 128G, 256G, and 512G[1]

      Up to 18 TB using 24x256G DDR4 DIMMs and 24x512G Intel® Optane DC Persistent Memory Modules

      Cisco FlexStorage storage subsystem

      Five mezzanine adapters and support for up to four NVIDIA GPUs

      Cisco UCS Virtual Interface Card (VIC) 1340 modular LAN on motherboard (mLOM) and upcoming fourth-generation VIC mLOM

      Internal Secure Digital (SD) and M.2 boot options

[1] Requires a DDR4 DIMM for deployment (e.g. 12 Intel Optane DC Persistent Memory Modules require 12 DDR4 DIMMs). The sizes of DCPMM must be the same and the DDR4 DIMMS must the same. But between the DCPMM and DIMMs, the sizes may vary, as shown in the 18-TB configuration described earlier in this data sheet.
