Cisco ONC Installation

This section contains the following topics:

Installation Requirements

Before installing Cisco ONC, you must install Cisco Crosswork Infrastructure 4.4.

The infrastucture requirements for installing Cisco Crosswork are listed below. For complete installation requirements, see the Cisco Crosswork Infrastructure 4.4 and Applications Installation Guide.

Data Center Requirements

Cisco Crosswork can be deployed in either a vCenter managed data center or onto Cisco CSP. To aid in the deployment, Cisco has developed a cluster installation tool. This tool works in both environments. However, there are limitations to the tool which are detailed later in this section.


Note

  • The machine where you run the installer must have network connectivity to the data center (vCenter or CSP) where you plan to install the cluster. If this mandatory requirement cannot be met, you must manually install the cluster.

  • Cisco Crosswork cluster VMs (Hybrid nodes and Worker nodes) must be hosted on hardware with Hyper Threading disabled.

  • Ensure that the host resources are not oversubscribed (in terms of CPU or memory).

VMware Data Center Requirements

This section explains the data center requirements to install Cisco Crosswork on VMware vCenter.


Note

The following requirements are mandatory if you are planning to install Cisco Crosswork using the cluster installer. If your vCenter data center does not meet these requirements, then the VMs have to be deployed individually, and connectivity has to be established manually between the VMs.

  • Hypervisor and vCenter supported:

    • VMware vSphere 6.7 or above

    • VMware vCenter Server 7.0 and ESXi 7.0.

    • VMware vCenter Server 6.7 (Update 3g or later) and ESXi 6.7 (Update 1)

  • All the physical host machines must be organized within the same VMware Data Center, and while it is possible to deploy all the cluster nodes on a single physical host (provided it meets the requirements), it is recommended that the nodes be distributed across multiple physical hosts.

  • The networks required for the Crosswork Management and Data networks need to be built and configured in the data centers, and must allow low latency L2 communication.

  • To allow use of VRRP, DVS Port group needs to be set as follows:

    Property Value

    Promiscuous mode

    Reject

    MAC address changes

    Reject

    Forged transmits

    Accept

    To edit the settings in vCenter, navigate to the Host > Configure > Networking > Virtual Switches, and select the virtual switch. In the virtual switch, select Edit > Security and confirm the settings as suggested. Repeat the process for each virtual switch used in the cluster.

  • Ensure the user account you use for accessing vCenter has the following privileges:

    • VM (Provisioning): Clone VM on the VM you are cloning.

    • VM (Provisioning): Customize on the VM or VM folder if you are customizing the guest operating system.

    • VM (Inventory): Create from the existing VM on the data center or VM folder.

    • VM (Configuration): Add new disk on the data center or VM folder.

    • Resource: Assign VM to resource pool on the destination host, cluster, or resource pool.

    • Datastore: Allocate space on the destination datastore or datastore folder.

    • Network: Assign network to which the VM will be assigned.

    • Profile-driven storage (Query): This permission setting needs to be allowed at the root of the DC tree level.

  • We also recommend you to enable vCenter storage control.

CSP Data Center Requirements

This section explains the data center requirements to install Cisco Crosswork on Cisco Cloud Services Platform (CSP).

  • Cisco CSP, Release 2.8.0.276

  • Compatible hardware:

    UCSC-C220-M4S, UCSC-C240-M4SX

    N1K-1110-X, N1K-1110-S

    CSP-2100, CSP-2100-UCSD, CSP-2100-X1, CSP-2100-X2

    CSP-5200, CSP-5216, CSP-5228

    CSP-5400, CSP-5436, CSP-5444, CSP-5456

  • CSP host or cluster is setup and installed with a minimum of two physical ethernet interfaces - one ethernet connected to the Management network, and the other to the Data network.

VM Host Requirements

This section explains the VM host requirements.

Table 1. VM Host Requirements

Requirement

Description

CPU/Memory/Storage Profiles (per VM)

The data center host platform has to accommodate three VMs of the following minimum configuration:

VMware vCenter:

  • Large: 12 vCPUs | 96 GB RAM Memory | 1 TB disk space

Cisco CSP:

  • Large: 12 CPU cores | 96 GB RAM Memory | 1 TB disk space

Note 

For assistance in adjusting VM Memory and CPU sizes post installation, contact your Cisco Customer Experience team.

Few things to note:

  • Storage requirements vary based on factors such as the number of devices being supported and the type of deployment selected. However, 1 TB disk space should work for most deployments.

  • Due to their performance, solid state drives (SSD) are preferred over traditional hard disk drives (HDD).

  • If you are using HDD, the minimum speed should be over 10,000 RPM.

  • The VM data store(s) need to have disk access latency of < 10 ms.

Additional Storage

10 GB (approximately) of storage is required for the Crosswork OVA (in vCenter), OR the Crosswork QCOW2 image on each CSP node (in CSP).

Network Connections

For production deployments, we recommend that you use dual interfaces, one for the Management network and one for the Data network.

For optimal performance, the Management and Data networks should use links configured at a minimum of 10 Gbps.

IP Addresses

Two IP subnets, one for the Management network and one for Data network, with each allowing a minimum of four assignable IP addresses (IPv4 or IPv6). A Virtual IP (VIP) address is used to access the cluster, and then three IP addresses for each VM in the cluster. If your deployment requires worker nodes, you will need a Management and Data IP address for each worker node.

  • The IP addresses must be able to reach the gateway address for the network where Cisco Crosswork Data Gateway will be installed, or the installation will fail.

  • When deploying a IPv6 cluster, the installer needs to run on an IPv6 enabled container/VM.

  • At this time, your IP allocation is permanent and cannot be changed without re-deployment. For more information, contact your Cisco Customer Experience team.

NTP Servers

The IPv4 or IPv6 addresses or host names of the NTP servers you plan to use. If you want to enter multiple NTP servers, separate them with spaces. These should be the same NTP servers you use to synchronize the Crosswork application VM clock, devices, clients, and servers across your network.

  • Ensure that the NTP servers are reachable on the network before attempting installation. The installation will fail if the servers cannot be reached.

  • The ESXi hosts that will run the Crosswork application and Crosswork Data Gateway VM must have NTP configured, or the initial handshake may fail with "certificate not valid" errors.

DNS Servers

The IPv4 or IPv6 addresses of the DNS servers you plan to use. These should be the same DNS servers you use to resolve host names across your network.

  • Ensure that the DNS servers are reachable on the network before attempting installation. The installation will fail if the servers cannot be reached.

DNS Search Domain

The search domain you want to use with the DNS servers, for example, cisco.com. You can have only one search domain.

Important Notes

  • Cisco Crosswork Infrastructure and applications are built to run as a distributed collection of containers managed by Kubernetes. The number of containers varies as applications are added or deleted.

  • Dual stack configuration is not supported in Crosswork Platform Infrastructure. Therefore, all addresses for the environment must be either IPv4 or IPv6.
