Solution overviewCisco publicAbout thisdocumentThe challengeThis document is designedto help you learn what youneed to know about CiscoUnified Computing System(Cisco UCS ) to the level ofdepth that interests you.The digital business transformation is upon us, and it is creating newdemands on IT organizations: The challenge describesthe stresses facing ITorganizations today. The solution discusses themost important reasonswhy Cisco UCS is sucha compelling solution fortoday’s challenges. Cisco UCS anatomygives a nuts-and-boltsdescription of CiscoUCS in terms of howour components—CiscoUnified Fabric, Cisco UCSmanagement, and CiscoUCS servers—combineto create a single unifiedsystem. The next three sections,Unified I/O architecture,Cisco UCS management,and Cisco UCS serverstake a deep dive into thetechnology behind CiscoUCS. 2009–2019 Cisco and/or its affiliates. All rights reserved. Applications: Modern applications are becoming less monolithic andmore like organic entities that grow and shrink through the use of modular,distributed microservices. This reduces dependence on traditional ITinfrastructure and places new demands on IT organizations in terms of thelarge number of endpoints to manage and flexible infrastructure needed tosupport them. With agile development and DevOps deployment approachesbecoming the norm, developers and administrators demand the capability toprogram their own infrastructure. This is necessary in order to quickly roll outnew applications and updates to existing ones. Management: The main issue for IT organizations is managing infrastructureat scale and being able to match resources to application requirements—yetmanage all of the different types of infrastructure in a simple, holistic fashion.Furthermore, the IT organization’s clients—line-of-business managers,application developers, and DevOps teams—are asserting increasinginfluence over the adoption, purchase, and deployment of technology. ITorganizations saddled with ponderous management tools are hard pressedto compete with the fluidity of self-service, multicloud environments thattheir clients can purchase on their own if the IT organization doesn’tkeep pace. Location: Once upon a time traditional IT organizations could support andmanage their clients and applications safely within the glass walls of anon-premises data center. Now they must support clients, applications, andworkloads in public, managed, edge, and private cloud environments—all while maintaining compliance with best practices, business andgovernmental regulations, and data sovereignty requirements.As a modern IT organization, the challenge is to meet the needs ofthe digital business transformation while still supporting the traditional,monolithic applications that are the foundation of your business. You haveto simultaneously embrace the traditional deployment model and the fluidnature of today’s multicloud deployments. Page 4

Solution overviewCisco publicThe solutionThe straightforward solution to today’s data center challenges is CiscoUnified Computing System (Cisco UCS ). It’s not a collection of servers.It’s a fully self-aware, self-integrating system. Because it is 100 percentprogrammable, it has been the solution to computing challenges formore than 63,000 customers since 2009. The system is flexible, agile,and adaptable, and the portfolio of products supported by Cisco UCSincludes blade, rack, multinode, and storage-intensive servers; convergedinfrastructure; hyperconverged infrastructure (Cisco HyperFlex systems);and solutions for the network edge such as Cisco UCS Mini and CiscoHyperFlex Edge.There is a fundamental difference between vendors that sell serversand Cisco Unified Computing System. Servers arose as more powerfulpersonal computers, taking many of their attributes, including timeconsuming, manual, error-prone configuration of I/O, network, and storagesubsystems. Traditional servers are monolithic, complex to deploy, andeven more complex to adapt to new workload demands. In contrast, CiscoUCS is a single unified system, with six fundamental attributes that make itrevolutionary.Fabric centricWe blend all of the system’s I/O traffic into a single shared active-activenetwork that carries all modes of communication from servers to the outsideworld. Our low-latency, high-bandwidth network fabric is a shared resourceso networking can be allocated to interfaces based on policies rather thanphysical interface configuration and hard-wired cabling. The result is that youcan provision and balance resources to meet your workload needs easily.Endpoint awareCisco UCS was developed in the virtualization era, where the norm wasmultiple independent workloads running on the same server. Today thenumber of workloads has become practically unimaginable as containerizedenvironments place hundreds of workloads in a single virtual machine.Whether you run virtualized, containerized, or bare-metal workloads, all I/Ois virtualized. This gives you the capability to support a massive number ofendpoints but with a level of control equivalent to each endpoint having itsown dedicated (but virtual) cable to the outside world. This gives you thescale of virtualized, with the workload isolation and security of thephysical world. 2009–2019 Cisco and/or its affiliates. All rights reserved. Page 5

Solution overviewCisco public100 percent programmableFrom the very beginning, Cisco UCS was designed with the entire stateof each server—identity, configuration, and connectivity—abstracted intosoftware. This makes our system 100 percent programmable, easy toadapt to the varying requirements of both modern workloads and traditionalmonolithic business applications. With a completely programmable system,you can give your clients the level of control they need to manage theirworkloads. For global organizations, Cisco Intersight software-as-a-servicemanagement gives you complete role- and policy-based control over all ofyour resources regardless of where they reside. Fine-grained infrastructuremanagement can be handled in Agile development and DevOps shops withscripting languages that provide access to the Cisco UCS unified API.Intent basedCisco Intersight software helps you to more precisely align your infrastructurewith the needs of your business. It enables administrators to automateconfigurations or tasks based on specific requirements that are tied tobusiness objectives and application performance. Rather than having tobe concerned with every detail of system configuration, intent-basedmanagement enables you to describe what you want to accomplish, with thecloud-based automation we provide translating your intent into action.Delivers business benefitsOur policy-based approach to management gives you the simplicity,automation, and capabilities you need to increase productivity and support afast-paced business environment. Improved staff productivity: By aligning your infrastructure withapplications and the way teams work together, you can create synergies thatcan’t be achieved with other architectures. Better use of IT staff: The common, simplified management of servers,storage, and fabric establishes best practices and eliminates the need tounderstand the nuances of specific components. You can use your subjectmatter experts to develop policies and use lower-level administrators oroperations personnel to implement policies. Effective communication: Cisco UCS management improvescommunication between roles through cross-visibility and role-basedadministrative access. Faster time to value: You can rapidly roll out new applications and businessservices at cloud-like speed and enhance the competitive strength of yourenterprise. 2009–2019 Cisco and/or its affiliates.

Solution overviewCisco publicCisco UCS managementCisco UCS Manager integrates blade, rack, and storage servers into asingle self-aware, self-integrating, unified system. It quickly and accuratelyconfigures computing, network, storage, and storage-access resourcesto increase compliance and reduce the chance of errors that can causedowntime. Its role- and policy-based approach helps organizations moreeasily align policies and configurations with workloads. It automates systemconfiguration through a “create once, deploy many” approach.Integrated managementCisco UCS Manager is embedded in the system’s fabric interconnects andruns in a redundant, high-availability configuration. It is the closest point ofmanagement to the network and servers, so it is able to detect changes tothe physical configuration and respond in real time, whether it is new bladeservers slid into a chassis or an additional cable used to increase bandwidth.It can be accessed directly through an intuitive HTML 5 GUI or command-lineinterface (CLI). Cisco UCS Manager is also accessed through its API, whichsupports an entire ecosystem of management tools: Cisco Intersight software as a service is cloud-based automation andmanagement that provides a consistent interface for all of your Cisco UCSand Cisco HyperFlex systems regardless of their location. Cisco Intersightsoftware accesses Cisco UCS and Cisco HyperFlex systems through aSecure Sockets Layer (SSL) connection from the cloud. Cisco UCS Director provides complete software lifecycle orchestration andmanagement. Through a workflow-based approach, you can manage theallocation of physical and virtual infrastructure needed to deploy applications,including servers, networking, and third-party storage. Cisco UCS Directoris an essential component of Cisco Integrated Infrastructure offerings thatcombine Cisco UCS with storage from industry-leading vendors to createeffective and easily deployed solutions. Cisco UCS Central Software extends Cisco UCS Manager functions sothat they can be uniformly implemented across your entire organization.For example, Cisco UCS service profiles that define how particular types ofservers are configured can be centrally defined and uniformly applied acrossyour entire organization, regardless of size. Cisco UCS Central Software ishosted in your own data centers, in contrast to Cisco Intersight software,which is deployed and managed by Cisco in the cloud. An entire ecosystem of third-party management tools integrate with CiscoUCS through the Cisco UCS management API. 2009–2019 Cisco and/or its affiliates. All rights reserved. Page 9

Solution overviewCisco publicCiscoSingleConnecttechnologyCisco SingleConnecttechnology is based on ahigh-bandwidth, low-latencyunified fabric that combinesLAN, SAN, and managementtraffic on a single set ofcables.LANSANManagementCisco SingleConnect technologySingleConnect technology provides an exceptionally easy, intelligent, andefficient way to connect and manage computing in the data center. Anexclusive Cisco innovation, SingleConnect technology dramatically simplifiesthe way that data centers connect to rack and blade servers; physical serversand virtual machines; and LAN, SAN, and management networks.Cisco UCS fabric interconnectsCisco UCS fabric interconnects provide a single point of connectivity andmanagement for an entire Cisco UCS or Cisco HyperFlex system. Deployedas an active-active pair, the system’s fabric interconnects integrate allcomponents into a single, highly available management domain controlled byCisco UCS Manager. The fabric interconnects manage all I/O efficiently andsecurely at a single point, resulting in deterministic I/O latency regardlessof a server or virtual machine’s topological location in the system. Ciscofabric interconnects support low-latency, line-rate, lossless Ethernet andFibre Channel over Ethernet (FCoE) connectivity. the Cisco UCS 6300 SeriesFabric Interconnects supports 10- and 40-Gbps connectivity, and the CiscoUCS 6454 supports 10 and 25 Gbps. For remote and edge locations, bladeresident Cisco UCS 6324 Fabric Interconnects can be used to create a selfcontained Cisco UCS Mini solution for branch offices and remote locations.Cisco fabric extendersCisco fabric extenders are zero-management, low-cost, low-powerconsuming devices that distribute the system’s connectivity and managementplanes to rack servers and blade chassis to scale the system without addingcomplex switches or management points. Cisco fabric extenders eliminatethe need for top-of-rack switches and blade-server-resident Ethernet andFibre Channel switches and management modules, dramatically reducing theinfrastructure cost per server. Rack and storage servers can be connecteddirectly to Cisco fabric interconnects for outstanding dedicated networkbandwidth. Rack servers can be connected through fabric extenders forincreased scale. Regardless of connectivity method, all servers are integratedthrough single-wire management in which all network, storage-access, andmanagement traffic is carried over a single set of cables.Cisco UCS virtual interface cardsCisco UCS virtual interface cards (VICs), extend the network fabric directlyto both servers and virtual switches so that a single connectivity mechanismcan be used to connect both physical and virtual servers with the same levelof visibility and control. Cisco VICs provide complete programmability of theCisco UCS I/O infrastructure, with the number and type of I/O interfacesconfigurable on demand with a zero-touch model. 2009–2019 Cisco and/or its affiliates.

Solution overviewCisco publicBlade server chassisThe Cisco UCS 5108 Blade Server Chassis features flexible bayconfigurations for blade servers. It can support up to eight half-width blades,up to four full-width blades in a compact 6-rack-unit (6RU) form factor. Theblade chassis is a highly simplified device, in contrast to traditional bladechassis that host multiple switches and management modules.The chassis adds no points of management to the system because it islogically part of the fabric interconnects. The Cisco UCS 5100 Series BladeServer Chassis hosts two fabric extenders: low-power-consuming devicesthat leave the chassis with the power budget and sufficient airflow to supportmultiple future generations of blade servers and network connectivityoptions. A chassis can be deployed as a standalone Cisco UCS Mini solutionby installing two Cisco UCS 6324 Fabric Interconnects in the slots that wouldnormally be used for the fabric extenders.Cisco UCS serversDelivering performance, versatility, and density in servers designed withoutcompromise, Cisco UCS blade, rack, multinode, and storage servers canpower every workload, including (but not limited to) workloads for: Agile development environments requiring bare-metal servers Artificial intelligence and machine learning applications Big data Content delivery Cloud computing environments delivering virtual machines and bare-metalservers as a service Database management systems High-frequency trading Hyperconverged applications: Cisco HyperFlex nodes are based on CiscoUCS servers. Gaming applications Internet infrastructure applications Mission-critical enterprise applications Mobile application back-end services Virtualized environmentsCisco UCS is designed so that it is logically a single very large blade serverchassis in which every server in our product line can connect and bemanaged as if it were part of the same single, unified system. In this sense,Cisco UCS is form-factor neutral, giving you more flexibility to choose theservers that best meet your needs without the penalty of having to use adifferent management approach for each type of server (Figure 2). 2009–2019 Cisco and/or its affiliates.

Our blade servers areavailable in two form factors (half-width and full-width) with two or fourIntel Xeon processors. Blade servers use modular LAN on motherboard(mLOM) or mezzanine-form-factor Cisco VICs to increase I/O flexibility andaccelerate deployment. Cisco UCS C-Series Rack Servers can integrate into Cisco UCS throughCisco UCS fabric interconnects or be used as standalone servers withCisco or third-party switches. With world-record-setting performance for2- and 4-socket servers, Cisco rack and storage servers can integrate intoCisco UCS through a single set of cables. These servers provide a widerange of I/O, memory, internal disk, solid-state disk (SSD) drive and NVMestorage device capacity, enabling you to easily match servers to workloads.The Cisco UCS C480 ML M5 server is designed for artificial intelligenceand machine learning workloads. It’s purpose-specific design incorporateseight NVIDIA V100 SMX2 32-GB graphics processing units GPUs to powercompute-intensive deep learning applications.

To achieve this density, we have equippedthe Cisco UCS C125 M5 Rack Server Node with up to two AMD EPYC processors. With the highest core density in the industry, large memorycapacity, superior memory bandwidth, massive I/O capacity, and dedicateddisk storage, AMD EPYC processors combined with Cisco UCS C125Rack Server Nodes brings more performance with less complexity to highintensity compute clusters. Cisco UCS S-Series Storage Servers are modular servers that supportup to 60 large-form-factor internal drives to support storage-intensiveworkloads including big data, content streaming, online backup, andstorage-as-a-service applications. The servers support one or twocomputing nodes with up to two CPUs each, and with up 160 Gbps ofunified fabric connectivity per node. These features simplify the process ofdeploying just the right amount of resources to most efficiently supportyour applications.Cisco UCS physical connectivity optionsA pair of Cisco UCS fabric interconnects forms the single point ofconnectivity for a Cisco UCS domain. Blade servers connect through fabricextenders, most rack servers can connect through optional fabric extenders,and rack servers, multinode rack servers, and storage servers can connectdirectly to the fabric interconnects as illustrated in Figure 3. Blade server chassis can be connected to the fabric interconnectsthrough a pair of blade-chassis-resident fabric extenders.
