Windows Server “8” Beta Hyper-V Component Architecture Poster
Hyper-V Hyper-V Replica Hyper-V Networking Virtual Machine Replication Load Balancing and Failover Quality of Service Bandwidth Management Hyper-V Replica is an asynchronous virtual machine replication technology that is included in Windows Server “8” Beta. It is designed for business continuity and disaster recovery. It works with any server, Network adapter teaming, also known as NIC teaming or load balancing and failover (LBFO), enables Windows Server “8” Beta includes new Quality of Service (QoS) bandwidth management network, or storage vendor. It does not require any shared storage. It enables you to replicate individual or multiple virtual machines. Hyper-V Replica is tightly integrated with Hyper-V and Failover multiple network adapters to be placed into a team interface. This provides bandwidth aggregation and functionality that allows you to converge multiple types of network traffic through a Clustering. You can replicate virtual machines from one computer running Hyper-V at a primary site (the primary server) to another computer running Hyper-V at a Replica site (the Replica server). The traffic failover, which prevents loss of connectivity in the event of a network adapter failure. Network single network adapter with a predicable level of service to each type. You can configure Replica server accepts incoming replication traffic from one or more primary servers. bandwidth management features through the virtual machine settings or by using adapter teaming supports multivendor implementations.

Supports teamed Configurations for Network Adapter Teaming To architect bandwidth management, you can specify a maximum and minimum virtual adapters Operating System Switch-independent mode does not require the bandwidth limit. These limits allow you to manage bandwidth allocations depending on Initial Replication Mode physical switch to participate in teaming. The your type of network traffic. Before virtual machine replication can start, an initial copy of all virtual hard disks (VHDs) Virtual Virtual Primary Server must be transferred to the Replica server.
