Features and Benefits
The Cisco UCS 5108 revolutionizes the use and deployment of blade-based systems. By incorporating unified fabric, integrated, embedded management, and I/O Module technology, the Cisco Unified Computing System enables the chassis to have fewer physical components, no independent management, and to be more energy efficient than traditional blade server chassis.
This simplicity eliminates the need for dedicated chassis management and blade switches, reduces cabling, and enables the Cisco Unified Computing System to scale to 40 chassis without adding complexity. The Cisco UCS 5108 chassis is a critical component in delivering the Cisco Unified Computing System benefits of data center simplicity and IT responsiveness.
Table 1-1 summarizes the features and benefits of the Cisco UCS 5108.
Components
Cisco UCS 5108 Server Chassis (N20-C6508 or UCSB-5108-DC)
The Cisco UCS 5100 Series Blade Server Chassis is a scalable and flexible blade server chassis for today's and tomorrow's data center while helping reduce total cost of ownership.It is available configured for AC and DC power environments.
Cisco's first blade server chassis offering, the Cisco UCS 5108 Blade Server Chassis (Figure 1-1), is six rack units (6 RU) high and can mount in an industry-standard 19-inch rack with square holes (such as the Cisco R Series Racks) or in round hole racks when an adapter is used. The chassis can house up to eight half-width Cisco UCS B-Series Blade Servers and can accommodate both half- and full-width blade form factors.
Four single-phase, hot-swappable AC or DC power supplies are accessible from the front of the chassis. These power supplies are 92 percent efficient and can be configured to support nonredundant, N+1 redundant, and grid-redundant configurations. The rear of the chassis contains eight hot-swappable fans, four power connectors (one per power supply), and two I/O bays for I/O modules. A passive midplane provides up to an effective maximum of 20 Gbps of I/O bandwidth per server slot and up to 40 Gbps of I/O bandwidth for two slots, the midplane is built to eventually support 80Gbps per slot.
Scalability is dependant on both hardware and software. For more information, refer to the "I/OM Upgrade Considerations" section and to the appropriate UCS software release notes.

Adapter Cards
Cisco UCS Virtual Interface Card 1280
The Cisco UCS Virtual Interface Card 1280 (UCS-VIC-M82-8P) is an eight-port 10 Gigabit Ethernet, Fibre Channel over Ethernet (FCoE)-capable mezzanine card designed exclusively for Cisco UCS B-Series Blade Servers. The card enables a policy-based, stateless, agile server infrastructure that can present up to 256 PCIe standards-compliant interfaces to the host that can be dynamically configured as either network interface cards (NICs) or host bus adapters (HBAs). In addition, the Cisco UCS Virtual Interface Card 1280 supports Cisco Virtual Machine Fabric Extender (VM-FEX) technology, which extends the Cisco UCS Fabric Interconnect ports to virtual machines, simplifying server virtualization deployment.
Cisco UCS M81KR Virtual Interface Card
The Cisco UCS M81KR Virtual Interface Card is a virtualization-optimized Fibre Channel over Ethernet (FCoE) adapter card. The virtual interface card is a dual-port 10 Gigabit Ethernet adapter card that supports up to 128 Peripheral Component Interconnect Express (PCIe) standards-compliant virtual interfaces that 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 [WWNN]) are established using just-in-time provisioning. In addition, the Cisco UCS M81KR supports network interface virtualization and Cisco VN-Link technology.
Unique to the Cisco Unified Computing System, the Cisco UCS M81KR is designed for both traditional operating system and virtualization environments. It is optimized for virtualized environments, for organizations that seek increased mobility in their physical environments, and for data centers that want reduced TCO through NIC, HBA, cabling, and switch reduction.
The Cisco UCS M81KR presents up to 128 virtual interfaces to the operating system on a given blade. The 128 virtual interfaces can be dynamically configured by Cisco UCS Manager as either Fibre Channel or Ethernet devices. Deployment of applications using multiple Ethernet and Fibre Channel interfaces is no longer constrained by the available physical adapters. To an operating system or a hypervisor running on a Cisco UCS B-Series Blade Server, the virtual interfaces appear as regular PCIe devices.
The Cisco UCS M81KR has built-in architectural support enabling the virtual machine to directly access the adapter. I/O bottlenecks and memory performance can be improved by providing virtual machines direct access to hardware I/O devices, eliminating the overhead of embedded software switches.
The Cisco UCS M81KR also brings adapter consolidation to physical environments. The adapter can be defined as multiple different NICs and HBAs. For example, one adapter card can replace two quad-port NICs and two single-port HBAs, resulting in fewer NICs, HBAs, switches, and cables.
Cisco UCS 82598KR-CI 10 Gigabit Ethernet Adapter
The Cisco UCS 82598KR-CI 10 Gigabit Ethernet adapter is based on the Intel 82598 10 Gigabit Ethernet controller, which is designed for efficient high-performance Ethernet transport. It provides a solution for data center environments that need low-latency 10 Gigabit Ethernet transport capability, and a dual-port connection to the midplane of the blade server chassis.
The Cisco UCS 82598KR-CI supports Intel Input/Output Acceleration Technology (I/OAT) as well as virtual queues for I/O virtualization. The adapter is energy efficient and can also help reduce CPU utilization by providing large segment offload (LSO) and TCP segmentation offload (TSO). The Cisco UCS 82598KR-CI uses Intel Virtual Machine Device Queue (VMDq) technology for the efficient routing of packets to the appropriate virtual machine.
Cisco UCS M71KR-E Emulex Converged Network Adapter
The Cisco UCS M71KR-E Emulex Converged Network Adapter (CNA) is an Emulex-based Fibre Channel over Ethernet (FCoE) adapter card that provides connectivity for Cisco UCS B-Series Blade Servers in the Cisco Unified Computing System.

Cisco UCS 2100 Series I/O Modules bring the unified fabric into the blade server enclosure, providing 10 Gigabit Ethernet connections between blade servers and the fabric interconnect, simplifying diagnostics, cabling, and management.
The Cisco UCS 2100 Series extends the I/O fabric between the fabric interconnects and the Cisco UCS 5100 Series Blade Server Chassis, enabling a lossless and deterministic Fibre Channel over Ethernet (FCoE) fabric to connect all blades and chassis together. Since the I/O Module is similar to a distributed line card, it does not do any switching and is managed as an extension of the fabric interconnects. This approach removes switching from the chassis, reducing overall infrastructure complexity and enabling the Cisco Unified Computing System to scale to many chassis without multiplying the number of switches needed, reducing TCO and allowing all chassis to be managed as a single, highly available management domain.
The Cisco 2100 Series also manages the chassis environment (the power supply and fans as well as the blades) in conjunction with the fabric interconnect. Therefore, separate chassis management modules are not required.
Cisco UCS 2100 Series I/O Modules fit into the back of the Cisco UCS 5100 Series chassis. Each Cisco UCS 5100 Series chassis can support up to two I/O modules, enabling increased capacity as well as redundancy.
LEDs
There are 4 port activity LEDs, and an LED indicating connectivity to the servers in the chassis.
Buttons
There are no buttons on the I/O module.
Connectors
There are four I./O ports supporting SFP+ 10 Gb Ethernet connections. There is also a console connection for use by Cisco diagnostic technicians. It is not intended for customer use.

Fan Modules (N20-FAN5)
The chassis can accept up to eight fan modules. A chassis must have filler plates in place if no fan in a slot for an extended period.
LEDs

Power Supplies (N20-PAC5-2500W and UCSB-PSU-2500DC48)
To determine the number of power supplies needed for a given configuration, refer the Cisco UCS Power Calculator.
LEDs
There are two LEDs indicating power connection, AC or DC power supply operation, and fault states. See Interpreting LEDs for details.
Buttons
There are no buttons on a power supply.
Connectors
Four single-phase, hot-swappable power supplies are accessible from the front of the chassis. These power supplies are 92 percent efficient and can be configured to support nonredundant, N+1 redundant, and grid-redundant configurations.
Power Supply Redundancy
Power Supply redundancy functions identically for AC and DC configured systems. When considering power supply redundancy you need to take several things into consideration:
•
•
–
–
To configure redundancy, use the UCS Manager GUI or use the scope psu-policy CLI command to enter PSU policy mode, then use the appropriate option for the set redundancy {grid | n-plus-1 | non-redund} command.
Non-redundant Mode
In a non-redundant or combined mode, all installed power supplies are turned on and balance the load evenly. Smaller configurations (requiring less than 2500W) can be powered by a single power supply when the system is using UCS Release 1.3(1) or earlier. However, a single power supply cannot provide redundancy and if either the power input or power supply fail, the system will immediately shut down. More common configurations require two or more power supplies (if requirements are between 2500 and 5000 watts peak) in non-redundant mode.
When using UCS Release 1.4(1) and later, the chassis requires a minimum of 2 power supplies.
Note
N+1 Redundancy
The N+1 redundancy configuration implies that the chassis contains a total number of power supplies to satisfy non-redundancy, plus one additional power supply for redundancy. All the power supplies that are participating in N+1 redundancy are turned on and equally share the power load for the chassis. If any additional power supplies are installed, UCS Manager recognizes these "unnecessary" power supplies and places them on standby.
If a power supply should fail, the surviving supplies can provide power to the chassis. In addition, UCS Manager turns on any "turned-off" power supplies to bring the system back to N+1 status.
To provide N+1 protection, the following number of power supplies is recommended:
•
•
Adding an additional power supply to either of these configurations will provide an extra level of protection. UCS Manager turns on the extra power supply in the event of a failure, and restores N+1 protection.
Note
Grid Redundancy
The grid redundant configuration is sometimes used when you have two power sources to power a chassis or you require greater than N+1 redundancy. If one source fails (which causes a loss of power to one or two power supplies), the surviving power supplies on the other power circuit continue to provide power to the chassis. A common reason for using grid redundancy is if the rack power distribution is such that power is provided by two PDUs and you want the grid redundancy protection in the case of a PDU failure.
To provide grid redundant (or greater than N+1) protection, the following number of power supplies is recommended:
•
•
