Implementing Cisco UCS Solutions

Chapter 1. Cisco UCS Physical Architecture and Installing UCS Hardware

In previous decades, computers evolved at a dramatic pace. Moore's law, which predicted that the density of transistors and integrated circuits would double every two years as computing components kept on shrinking in size while improving in computational capacity, has truly prevailed. This technological evolution led to three distinct generations of computing devices.

We witnessed the era of the following generations:

Gigantic mainframe computers
Commoditized personal computers and tower and rack servers (also known as pizza-box servers)
Blade servers (also known as modular servers)

Mainframes were monolithic systems often with proprietary hardware and software. With their enormous computing power, mainframes were able to run multiple applications; however, their major limitations were cost and many single points of failure. Due to their high cost and management complexity, mainframes remained mainly confined to military use, universities, and some very large organizations.

Tower and rack-mounted servers usually have limited computational resources as compared to mainframes; however, these are very cost effective. Because of the limited resources available on these servers, a one-to-one server-to-application ratio is usually the way to go. Because of this one server one application design, rack and tower servers need more rack space, separate cabling, individual power supplies, and more cooling in the datacenter, which makes management of the infrastructure quite complex. However, this second generation of computers is generally very cost effective. This led to the mass adoption of computers everywhere.

The latest trend in the ever evolving computer architecture space is to move away from tower and rack-mounted servers in favor of blade servers. In today's highly demanding enterprise applications, blade server architecture provides excellent features when compared with rack and tower servers. These features include the following:

Less rack space usage
Less cabling
Shared power
Consolidated I/O
Easy management
Excellent heating and cooling

Contemporary datacenters are facing unprecedented growth in computational demands alongside the need for reducing implementation and operational costs. Considering these factors, blade servers are designed to minimize the use of resources and space. Components in a blade chassis are either removed or shared between blade servers.

The minimum form factor of a rack server is 1 Rack Unit (RU). 1 RU is equal to 1.75 inches, and the most common server rack height is usually 42 RU. It is therefore possible to fit only 42 pizza-box servers in a standard rack. With blade servers, it is possible to achieve higher densities of servers per rack.

In a blade server, data connectivity interfaces and power supplies are also shared. Thus, blade servers also require less cabling, and hence less management.

In this chapter, we will discuss physical components of the Unified Computing System (UCS) equipment. The list of the topics covered in this chapter is as follows:

Looking at the UCS equipment

With the ever increasing demand on datacenters, vendors started focusing on different aspects of server and networking hardware consolidation; however, most of the ad hoc solutions were based on gluing together the existing products which were not designed grounds up to provide a cohesive infrastructure and failed to address the requirements of the datacenter as a whole. Hence, management of these amalgamated solutions was a nightmare for IT administrators.

Cisco entered into the blade server market with a holistic approach to the blade server design. With a strong background in networking and storage products, Cisco developed a cohesive solution consolidating the computing, network, and storage connectivity components along with centralized management of these resources. The purpose of Cisco UCS is to reduce the Total Cost of Ownership (TCO) and improve scalability and flexibility.

Salient features and benefits of the UCS solution include the following:

Stateless computing
Rapid provisioning of servers
Simplified troubleshooting
Virtualization readiness
Choice of industry-standard form factors
Extended memory technology for increased density

Stateless computing

Cisco introduced the idea of stateless computing with its blade server design. Cisco blade servers do not have any initial configuration. Universally Unique Identifiers (UUIDs) for blades, Network Interface Cards (NICs), Media Access Control (MAC) addresses, storage World Wide Node (WWN) numbers, firmware, and BIOS settings are all abstracted from Unified Computing System Manager (UCSM), the management software running on the FIs.

Rapid provisioning of servers

Provisioning of servers dramatically improves as the servers can be provisioned using the UCSM software even before they are physically available. Once the server is physically installed, it will abstract its identity from UCSM. Using server configuration templates, it is therefore possible to create a server template only once and apply the template to hundreds of servers.

Simplified troubleshooting

Replacement of servers also becomes very easy. Since the servers are stateless, as soon as a replacement server is installed, it will abstract all the configuration of the old server and will be available for use. Servers can also be easily migrated for different roles and workloads.

Virtualization readiness

Virtualization in the form of modern bare metal hypervisors is a major breakthrough for optimal utilization of computational resources. Cisco UCS solution supports all major hypervisor platforms including VMware ESX/ESXi, Microsoft Hyper-V, and Citrix Xen server. Support and integration with VMware vSphere solution is very strong. UCSM can be integrated with vCenter to abstract and manage features at the individual Virtual Machine (VM) level. By leveraging the benefits of virtualization and increasing the density of the physical server, the UCS solution can scale up to thousands of VMs.

Choice of industry-standard form factors

Cisco UCS servers are available in two categories: B-series blade servers and C-series rack-mount servers. Both form factors are designed using the same industry-standard components and can address different computational requirements. Both B-series blade servers and C-series rack-mount servers are designed using Intel Xeon CPUs. B-series servers are managed through UCSM, whereas C-series servers can either be individually managed or can be integrated to UCSM.

Extended memory technology for increased density

Cisco also introduced a patented extended memory technology for two CPU socket servers to increase the total amount of memory support; this could be more than double the amount of memory as compared to the industry standards for two socket servers. Virtualized workloads can leverage this extra memory to support an even greater density of VMs in a reduced physical footprint, resulting in reduced Capital Expenditure (CAPEX) and Operational Expenditure (OPEX) costs. Extended memory technology is available in both B-series blade servers and C-series rack-mount servers.

Understanding the physical architecture of UCS

The Cisco UCS solution can be divided into the following three main categories:

The Cisco UCS FIs
The Cisco UCS blade servers
The Cisco UCS rack-mount servers

The Cisco UCS FIs

The Cisco UCS FIs provide network connectivity and management for the connected servers. The UCS FIs run the UCSM control software and consist of the following components:

6100 series and 6200 series FIs
Transceivers for network and storage connectivity
Expansion modules for both FI series
UCSM software

The Cisco UCS blade servers

The Cisco UCS blade servers require a mother chassis where these servers can be installed. The UCS blade server solution consists of the following components:

A blade server chassis, used for installing blades
B-series blade servers
IOM modules for connectivity to the FIs
Transceivers for connectivity to the FIs
Mezzanine cards for network and storage connectivity

The Cisco UCS rack-mount servers

The Cisco UCS rack-mount servers are standalone servers that can be installed and controlled individually. Cisco provides Fabric Extenders (FEXs) for the rack-mount servers. FEXs can be used to connect and manage rack-mount servers from FIs. The UCS rack-mount server solution consists of the following components:

UCS C-series rack-mount servers
FEXs for connecting rack-mount servers to FIs

In this chapter we will provide details about hardware options available for both blade servers and rack-mount servers. Most of the field deployments of UCS servers are based on blade servers. Therefore, our main focus will be on blade server configuration in this book. However, if proper connectivity is established between rack-mount servers and FIs, rack-mount servers can also be managed in the same fashion.

The following figure depicts the FIs running the UCSM software, a blade server chassis with IOM modules, and the main components of a blade server:

In this chapter, we will go into the details of various UCS components and will focus on their physical specifications and installation in the subsequent sections.

Note

The Cisco interactive 3D model for Cisco 5100 series chassis and blades is an excellent resource for exploring Cisco UCS components physically. It is also available for iPhone/iPad (search for UCS Tech Specs in the marketplace). More details on this are available at http://www.cisco.com/en/US/prod/ps10265/ps10279/ucs_kaon_model_preso.html.

Understanding FIs

An FI is the core component of a UCS solution. FIs are typically configured as highly available clustered pairs in production environments. It's possible to run a single FI-based design as a proof of concept test deployment before actually implementing it in production. FIs provide the following two capabilities:

Network connectivity to both LAN and SAN
UCS infrastructure management through the embedded management software, UCSM, for both hardware and software management

FIs are available in two generations, namely Cisco UCS 6100 series and Cisco UCS 6200 series. The core functionality is the same in both generations; however, UCS 6200 series has a newer generation Application Specific Integrated Circuit (ASIC), higher throughput, and increased number of physical ports. Both generations can be upgraded to the latest UCSM software.

FIs provide converged ports. Depending on the physical Small Form Factor Pluggable (SFP) transceivers and FI software configuration, each port can be configured in different ways. Cisco 6200 series FI ports can be configured as Ethernet ports, Fiber Channel over Ethernet (FCoE) ports, or Fiber Channel (FC) ports. On the other hand, 6100 series converged ports only support Ethernet and FCoE (they also support FC, but only in the expansion slot).

In production, FIs are deployed in clustered pairs to provide high availability. Cisco-supported implementation requires that clustered FIs be identical. The only possibility for having different FIs in a cluster is during a cluster upgrade.

Tip

Larger enterprises may consider deploying the Cisco UCS central software, which can manage multiple UCS domains across globally distributed datacenters.

The following are the specifications of all the available UCS FIs.

The Cisco 6296UP FI

The Cisco 6296UP FI (UP represents Unified Ports) is a 2 RU device with a maximum of 96 converged ports. Ports can be configured as 1 GB Ethernet, 10 GB Ethernet, 10 GB FCoE, and 2/4/8 GB FC. The specifications of this FI are as follows:

A maximum of 20 blade server chassis per FI
A fabric throughput of 520 Gbps
A unit of 20 fixed ports with one expansion slot, which can provide eight 2/4/8 Gbps FC or six 10 Gbps ports

Note

Standard pricing of FIs provides a limited number of port licenses. To enable more ports, extra licenses can be purchased per port.

Exploring connectivity transceivers for FIs

A variety of SFP transceivers are available for both FI series. These transceivers provide south-bound IOM connectivity and north-bound network and storage connectivity. They are based on industry-standard SFP+ specifications.

Transceivers can be selected depending on the technology, for example, Ethernet or FC, and also according to the distance requirements. For shorter distances between FIs, IOMs, and north-bound network switches, twinax cables with integrated SFP is an economical alternative as compared to fiber optic SFP.

The most commonly used transceivers include the following:

Cisco SFP-10G-SR: This is a multimode optical fiber 10 Gbps Ethernet SFP that can be used for distances up to 400 meters.
Cisco SFP-10G-LR: This is a single-mode optical fiber 10 Gbps Ethernet SFP that can be used for distances up to 10 Km.
Cisco SFP-10G-FET: This is a low power consuming multimode fiber optic 10 Gbps Ethernet SFP that can be used for distances up to 100 meters.
Cisco SFP-H10GB-CUxM: These are the twinax cables providing low cost 10 Gbps Ethernet connectivity and are available in 1, 3, 5, and 7 meter fixed length configurations. The actual transceivers are named SFP-H10GB-CU1M, SFP-H10GB-CU3M, SFP-H10GB-CU5M, and SFP-H10GB-CU7M according to the length each twinax cable provides.
Cisco SFP-H10GB-ACU10M: This is a 10-meter-long twinax cable providing 10 Gbps Ethernet. At a length of 10 meters, this cable requires active transceivers at both ends.
DS-SFP-FCxG-xW: These are multi-mode and single-mode fiber optic FC transceivers that are available at 2, 4, and 8 Gbps transfer speeds. The actual transceivers are named DS-SFP-FC4G-SW and DS-SFP-FC8G-SW according to the speed and distance covered by the transceiver.

Note

Distance and other detailed specifications of the Cisco SFPs are available at http://www.cisco.com/en/US/prod/collateral/modules/ps5455/data_sheet_c78-455693.html.

The Cisco UCS 5100 series blade server chassis

The Cisco 5100 series blade server chassis is a vital building block of the Cisco UCS solution. Currently, there is only one generation of UCS blade chassis, which is Cisco UCS 5108. The chassis form factor is 6 RU and it can host the following:

A maximum of eight half-width blade servers
A maximum of four full-width blade servers
Any other combination of half-width blade and full-width blade servers is also possible

A look at the chassis front

The UCS chassis front is used to insert blade servers into the chassis. The front of the chassis also holds UCS power supplies. The UCS chassis front can hold the following hardware:

Eight half-width empty slots for a maximum of eight half-width blade servers with a removable divider in the middle; this can be removed for installing a maximum of four full-width blades or any other combination of half-width and full-width servers
Four slots for single power supplies; these slots can be configured as nonredundant, N+1 redundant, and grid redundant

This has been demonstrated in the following image:

A look at the chassis back

The UCS chassis back provides slots for IOM modules, fan units, and power connectors. It provides the following connectors:

Two slots for IOM modules that act as remote line cards to the FIs
Eight fan units
Four power supply connectors

This has been demonstrated in the following image:

Environmental requirements

The UCS chassis is designed for the industry-standard rack form factor. The following are the environmental requirements for the UCS chassis:

An industry-standard, four-post, 19 inch rack or cabinet is required as the chassis cannot be mounted onto a two-post relay rack because of its weight and length
It requires a 6 RU rack space
Ensure proper cooling and ventilation for the rack as chassis air flow is front to back and should not be obstructed
The operating temperature of the UCS is 10 to 35 degrees centigrade
The acoustic power level is 85 dBA under normal operation
The weight of an empty chassis is 136 kg, which requires special consideration for floor loading

Note

Due to the weight and size of the chassis, at least two persons are required to mount it to the rails. It is highly recommended to mount the chassis first and then insert the power supplies, fan units, and blade servers.

The use of a server lift is highly recommended. Chassis side handles are only for moving and adjusting the chassis in the rack.

Blade servers and rack-mount servers

While blade servers are the dominant deployment of the UCS solution, Cisco has strategically extended its offering to include the industry-standard rack-mount form factor as well in order to provide users a choice against the competing rack-mount server vendors such as HP, IBM, and Dell.

Learning more about blade servers

Blade servers are at the heart of the UCS solution and come in various system resource configurations in terms of CPU, memory, and hard disk capacity. All blade servers are based on Intel Xeon processors and there is no AMD option available. Small and Medium Businesses (SMBs) can choose from different blade configurations as per business needs.

Cisco also had UCS 250 M1/M2 blade servers which were discontinued in November 2012. You may still see these servers deployed in the field.

Learning more about rack-mount servers

A majority of server vendors manufacture rack-mount servers (also known as pizza-box servers). Cisco UCS C-series servers are available in the industry-standard rack-mount form which can be deployed for SMB remote offices and applications requiring dedicated equipment. Like B-series blade servers, these servers are also based on Intel Xeon processors and there is no AMD option available.

C-series servers can be managed independently through an out of band (OOB) web interface or can be integrated with the UCSM software. The embedded CIMC provides the following services:

Remote KVM to server console
Remote power management
Remote virtual media for operating system installation
Industry-standard IPMI support for monitoring
Standard SNMP traps for monitoring

Connecting and managing C-series rack servers through UCSM requires a connection through Nexus 2200 series FEXs, which act as line cards to the FIs.
