Probe: Hypervisor Redundancy Checks Probe (Virtual Infra)

Release: Juniper Apstra 5.0

date_range 04-Nov-24

arrow_backward

arrow_forward

Purpose

Detect hypervisor redundancy.

Source Processors

Hypervisor and connected leaf (generic graph)	output stage: hypervisor_and_leaf (text set) (generated from graph)
Hypervisor pnic and vnet (generic graph collector)	output stage: hypervisor_pnic_vnet (text set) (generated from graph)

Additional Processor(s)

Hypervisor and leaf count (set count)	input stage: hypervisor_and_leaf output stage: hypervisors_leaf_count (number set)
Hypervisor vnet pnic count (set count)	input stage: hypervisors_pnic_vnet output stage: hypervisors_vnet_pnic_count (number set)
Hypervisor without ToR Switch redundancy (range)	input stage: hypervisors_leaf_count output stage: hypervisor_single_leaf_anomaly (discrete state set)
Networks without link redundancy (range)	input stage: hypervisors_vnet_pnic_count output stage: hypervisor_vnet_single_pnic_anomaly (discrete state set)

Example Usage

NSX-T Integration - an anomaly is raised in cases without redundancy or a single point of failure (SPOF) in hypervisor connectivity. Examples include:

NSX-T transport nodes with a single non-LAG uplink towards ToR leaf devices in the fabric can result in a single point of failure (SPOF) for overlay traffic.
NSX-T transport nodes with a single LAG uplink with both members going to a single ToR leaf can result in a single point of failure (SPOF).
Lack of redundancy between fabric LAG dual-leaf devices and ESXi hosts.

For more information about this probe, from the blueprint, navigate to Analytics > Probes, click Create Probe, then select Instantiate Predefined Probe from the drop-down list. Select the probe from the Predefined Probe drop-down list to see details specific to the probe.
