Isolating different departments’ virtual machines can be a challenge on a shared network. When entire networks of virtual machines must be isolated, the challenge becomes even greater. Traditionally, VLANs have been used to isolate networks, but VLANs are very complex...
Failover Clustering has proven its value in making virtualized workloads highly available. We saw this in Windows Server 2008 using Quick Migration and then in Windows Server 2008 R2 with the addition of Live Migration. Failover Clustering can also play...
Virtualized data centers are becoming more popular and practical every day. IT organizations and hosting providers have begun offering infrastructure as a service (IaaS), which provides more flexible, virtualized infrastructures to customers—“server instances on‑demand.” Because of this trend, IT organizations...
Hyper-V Replica Communications Architecture
Before Windows Server 2012
When you perform a live migration of a virtual machine between two computers that do not share an infrastructure, Hyper‑V first performs a partial migration of the virtual machine’s storage, as shown in the figure below.
With Windows Server 2012 RTM version available for all customers around the world, there is great news for organizations that are looking for a way to migrate virtual machines hosted on VMware vSphere to the Hyper-V host in Windows Server...
Before Windows Server 2012
Hyper-V Replica is new functionality added to the Hyper-V Role in Windows Server 2012. Hyper-V Replica enables organizations to implement an affordable Business Continuity and Disaster Recovery (BCDR) solution for virtualized workloads. This allows virtual machines running at a primary...
The process followed by Hyper-V internally to perform a storage migration is actually quite simple to explain and is as follows:
Replication state shows the current state of the replicating VM. It indicates whether the VM is being replicated, whether initial replication is pending etc.
Windows Server 2012 will provide a continuum of availability options to protect against a wide range of failure modes in different tiers – storage, network, and compute. These options will enable higher levels of availability and cost-effectiveness, as well as...
Hyper-V Replica requires the Failover Clustering role Hyper-V Replica Broker to be configured if either the primary or replica Hyper-V server is part of a cluster. This post builds on top of the guide and explains why the broker is...
In Windows Server 2012 there have been several enhancements to how Windows Server Failover Clusters integrate with the Active Directory. In this post we going to discuss some of the changes to help enable creating Failover Clusters in restrictive Active Directory environments where...
