Fabric Automation and Orchestration
XCO automates and orchestrates SLX IP fabrics, Extreme 8000 series, and tenant
networks, with support for the following:
- Building and managing small
data center (non-Clos) fabrics and 3-stage and 5-stage IP Clos fabrics
- Managing tenant-aware Layer 2
and Layer 3 networks
- Integrating Virtual
Management ecosystem platforms, such as VMWare vCenter and Microsoft
SCVMM
- Providing a single point of
configuration for your entire fabric
XCO consists of core K3s containerized services that interact with each other and
with other infrastructure services to provide the core functions of fabric and
tenant network automation. For more information, see XCO Microservices.
Deployment

- XCO on TPVM
- TPVM (Third-Party Virtual
Machine) is a guest VM that resides on Extreme SLX devices. You can run XCO from the SLX 9150, SLX
9250, Extreme 8520, Extreme 8720, Extreme 8820, or SLX 9740 TPVM. In this
context, XCO leverages the K3S
Kubernetes cluster as an underlying infrastructure for the XCO services deployment.
The K3S cluster is a single instance and an important component for
supporting high availability. A maximum of 24 devices is supported, either
24 devices in one fabric or 24 devices across multiple fabrics.
- XCO on an external VM
- You can deploy XCO on an external Virtual Machine to support more than 24 devices or based
on where tools are deployed in the data center.
- XCO for high availability
- A high-availability cluster
is a group of servers that provide continuous up time, or at least minimum
down time, for the applications on the servers in the group. If an
application on one server fails, another server in the cluster maintains the
availability of the service or application. You can install XCO on a two-node cluster, including on TPVM, for high availability.
