Cisco Nexus Switches

Cisco Nexus Switches serve as top-of-rack (TOR) leaf and end-of-rack (EOR) spine switches provide out-of-band (OOB) network connectivity between Ultra M components. Two switch models are used for the various Ultra M models:

Nexus 93180-YC-EX

Nexus 93180 switches serve as network leafs within the Ultra M solution. Each switch has 48 10/25-Gbps Small Form Pluggable Plus (SFP+) ports and 6 40/100-Gbps Quad SFP+ (QSFP+) uplink ports.

UCS C-Series Servers

Cisco UCS C240 M4S SFF servers and host the functions and virtual machines (VMs) required by Ultra M.

Server Functions and Quantities

Server functions and quantity differ depending on the Ultra M model you are deploying:

  • Ultra M Manager Node: Required only for Ultra M models based on the Hyper-Converged architecture, this server hosts the following:

    • OSP-D VM

  • OpenStack Controller Nodes: These servers host the high availability (HA) cluster that serves as the VIM within the Ultra M solution. In addition, they facilitate the Ceph storage monitor function required by the Ceph Storage Nodes and/or OSD Compute Nodes.

  • OSD Compute Nodes: Required only for Hyper-converged Ultra M models, these servers provide Ceph storage functionality in addition to hosting VMs for the following:

    • Elastic Services Controller (ESC) Virtual Network Function Manager (VNFM) active and standby VMs

    • Ultra Element Manager (UEM) VM HA cluster

    • Ultra Service Platform (USP) Control Function (CF) active and standby VMs

  • Compute Nodes: For all Ultra M models, these servers host the active, standby, and demux USP Service Function (SF) VMs.

Storage

UCS C240 Front-Plane displays the storage disk layout for the UCS C240 series servers used in the Ultra M solution.

Figure 1. UCS C240 Front-Plane

NOTES:

  • The Boot disks contain the operating system (OS) image with which to boot the server.

  • The Journal disks contain the Ceph journal file(s) used to repair any inconsistencies that may occur in the Object Storage Disks.

  • The Object Storage Disks store object data for USP-based VNFs.

  • Ensure that the HDD and SSD used for the Boot Disk, Journal Disk, and object storage devices (OSDs) are available as per the Ultra M BoM and installed in the appropriate slots as identified in Table 1.

  • Ensure that the RAIDs are sized such that:

    Boot Disks < Journal Disk(s) < OSDs

  • Ensure that FlexFlash is disabled on each UCS-C240 M4 (factory default).

  • Ensure that all nodes are in Unconfigured Good state under Cisco SAS RAID Controllers (factory default).
