Active On

Active On –

Active On (PN)” does not appear to be an official or widely recognized term from Microsoft documentation, especially in the context of Windows Server 8 (which later became Windows Server 2012). However, based on the phrasing and timing, it’s possible you’re referring to a feature or concept related to high availability and failover clustering improvements introduced in Windows Server 2012.

Here are some key availability improvements that were introduced in Windows Server 2012 (formerly codenamed Windows Server 8):

 High Availability Enhancements in Windows Server 2012:-

1. Cluster-Aware Updating (CAU)

Automatically updates nodes in a failover cluster without downtime, by shifting workloads during maintenance.

2. Improved Failover Clustering

  • Supports up to 64 nodes per cluster and 8,000 virtual machines per cluster.
  • Enhanced cluster validation and diagnostics.
  • Dynamic quorum and witness configuration for better resiliency.

3. VM Mobility & Live Migration

  • Live migration without shared storage.
  • Multiple concurrent live migrations supported.
  • Storage Live Migration lets you move a VM’s storage while it’s running.

4. Hyper-V Replica

Asynchronous replication of virtual machines between Hyper-V hosts, providing disaster recovery capabilities.

5. Continuous Availability for SMB

  • SMB 3.0 introduced with features like SMB Transparent Failover and SMB Multichannel for file server redundancy and performance.
