OVERVIEWOVERVIEWThe Cisco UCS C220 M4 LFF rack server is the newest 2-socket, 1U rack server from Cisco, designed forboth performance and expandability over a wide range of storage-intensive infrastructure workloads fromweb serving to distributed database.The enterprise-class UFCS C220 M4 LFF server extends the capabilities of Cisco’s Unified Computing Systemportfolio in a 1U form factor with the addition of the Intel Xeon E5-2600 v3 and v4 series processor familythat deliver significant performance and efficiency gains. In addition, the UCS C220 M4 SFF server provides24 DIMM slots, up to 4 drives and 2 x 1 GbE LAN-on-motherboard (LOM) ports delivering outstanding levels ofdensity and performance in a compact 1U package.The C220 M4 SFF server includes a modular LAN on motherboard (mLOM) slot for installation of a CiscoVirtual Interface Card (VIC) or third-party network interface card (NIC) without consuming a PCI slot inaddition to 2 x 1 GbE embedded (on the motherboard) LOM ports. These features combine to provideoutstanding levels of internal memory and storage expandability along with exceptional performance.The Cisco UCS C240 M4 LFF server can be used standalone, or as part of the Cisco Unified ComputingSystem, which unifies computing, networking, management, virtualization, and storage access into a singleintegrated architecture enabling end-to-end server visibility, management, and control in both bare metaland virtualized environments.Figure 1Cisco UCS C220 M4 High-Density LFF Rack ServerFront ViewRear ViewCisco UCS Cisco UCS C220 M4 High-Density Rack Server (Large Form Factor Disk Drive Model)3

CONFIGURING the SERVERSelect DIMMs and Memory MirroringSelect the memory configuration and whether or not you want the memory mirroring option.The available memory DIMMs and mirroring option are listed in Table 5.NOTE: When memory mirroring is enabled, the memory subsystem simultaneouslywrites identical data to two channels. If a memory read from one of the channelsreturns incorrect data due to an uncorrectable memory error, the systemautomatically retrieves the data from the other channel. A transient or soft error inone channel does not affect the mirrored data, and operation continues unless thereis a simultaneous error in exactly the same location on a DIMM and its mirroredDIMM. Memory mirroring reduces the amount of memory available to the operatingsystem by 50% because only one of the two populated channels provides data.Table 5 Available DDR4 DIMMsProduct ID (PID)PID DescriptionVoltageRanks/DIMM2400-MHz DIMM OptionsUCS-ML-1X644RV-A64GB DDR4-2400-MHz LRDIMM/PC4-19200/quad rank/x41.2 V4UCS-MR-1X322RV-A32GB DDR4-2400-MHz RDIMM/PC4-19200/dual rank/x41.2 V2UCS-MR-1X161RV-A16GB DDR4-2400-MHz RDIMM/PC4-19200/single rank/x41.2 V1UCS-MR-1X081RV-A8 GB DDR4-2400-MHz RDIMM/PC4-19200/single rank/x41.2 V1Memory Mirroring OptionN01-MMIRRORMemory mirroring optionApproved Configurations(1) 1-CPU configuration without memory mirroring: Select from 1 to 12 DIMMs. Refer to Memory Population Rules, page 64, for more detailedinformation.(2) 1-CPU configuration with memory mirroring: TotalNumberofDIMMs16Select 2, 4, 8, or 12 identical DIMMs. The DIMMs will be placed by the factory as shown in thefollowing table.CPU 1 DIMM Placement in Channels(for identical dual-rank DIMMs for 3DPC or identical quad-rank DIMMs for 2DPC)Blue SlotsBlack SlotsWhite SlotsCisco UCS Cisco UCS C220 M4 High-Density Rack Server (Large Form Factor Disk Drive Model)

CONFIGURING the SERVERCaveats System speed is dependent on how many DIMMs are populated per channel and the CPUDIMM speed support.

Available at a future date2. When you mix 2400 MHz RDIMMs of different sizes (for example, 8x32GB 8x16GB), the memory speed clocksone step down to 2133 MHz. The C220 M4 server supports four different memory reliability, availability, andserviceability (RAS) modes:—Independent Channel Mode—Mirrored Channel Mode—Lockstep Channel ModeBelow are the system level RAS Mode combination limitations:—Mixing of Independent and Lockstep channel mode is not allowed per platform.—Mixing of Non-Mirrored and Mirrored mode is not allowed per platform.—Mixing of Lockstep and Mirrored mode is not allowed per platform. Do not mix RDIMMs with LRDIMMs Do not mix 64GB DDR4-2133-MHz TSV-RDIMMs with any other DIMMs Single-rank DIMMs can be mixed with dual-rank DIMMs in the same channel Do not mix quad-rank DIMMs with single- or dual-rank DIMMs in the same channel For best performance, observe the following:Cisco UCS Cisco UCS C220 M4 High-Density Rack Server (Large Form Factor Disk Drive Model)19
CONFIGURING the SERVER—DIMMs with different timing parameters can be installed on different slots within thesame channel, but only timings that support the slowest DIMM will be applied to all.As a consequence, faster DIMMs will be operated at timings supported by the slowestDIMM populated.—When one DIMM is used, it must be populated in DIMM slot 1 (farthest away from theCPU) of a given channel.—When single, dual or quad rank DIMMs are populated for 2DPC or 3DPC, alwayspopulate the higher number rank DIMM first (starting from the farthest slot). For a3DPC example, first populate with quad-rank DIMMs in the DIMM slot 1. Thendual-rank DIMMs in the DIMM 2 slot. Then single-rank DIMMs in the DIMM 3 slot. DIMMs for CPU 1 and CPU 2 (when populated) must always be configured identically. When using mirroring, DIMMs must be installed in identical pairs across paired DDR4 buses.That is, mirrored pairs in channels A and B must be identical and pairs in channels C and Dmust be identical. However, the DIMMs used in channels A and B can be different from thosein channels C and D. Memory mirroring reduces the amount of available memory by 50% (quantity of DIMMs mustbe even for mirroring). Non-ECC DIMMs are not supported. Cisco memory from previous generation servers (DDR3) is not compatible with this serverFor more information regarding memory, see CPUs and DIMMs, page 63.20Cisco UCS Cisco UCS C220 M4 High-Density Rack Server (Large Form Factor Disk Drive Model)
