VM improvements There are three main areas of improvement for VMs on failover cluster VM node fairness VM node fairness facilitates the seamless load balancing of VMs across the nodes in a cluster. Overcommitted nodes are identified based on VM memory and CPU utilization on the node. VMs are then moved (live migrated) from an overcommitted node to nodes with available bandwidth. The aggressiveness of the balancing can be tuned to ensure optimal cluster performance and utilization. Node fairness is disabled when SCVMM Dynamic Optimization is turned on; otherwise, it is on by default VM start order VM start order handles the orchestration for VMs in a cluster. You now can group VMs into tiers and create start order dependencies between different tiers. This ensures that the most important VMs are started first. VMs are not started until the VMs on which they have a dependency are also started.

Storage Storage in a modern enterprise used to consist of traditional Fiber Channel or iSCSI storage arrays with shelves of drives. Windows Server 2016 new storage enhancements brings revolutionary new features within reach of every organization with its software-defined feature set. Storage Replica Storage Replica is a new feature in Windows Server 2016 with which you can set up storage-agnostic, block-level, synchronous replication between clusters or servers for disaster recovery. You also can use it to stretch a failover cluster across sites for high availability. Synchronous replication makes it possible for you to mirror data in physical sites with crash-consistent volumes, ensuring zero data loss at the file-system level. Asynchronous replication gives you the ability to extend sites beyond metropolitan ranges with the possibility of data loss. Storage Replica does not operate at a file level as does DFS Replication. Instead, it replicates data blocks and is therefore immune to issues of file locks, open handles, and so on. More info Storage Replica is a new feature in Windows Server 2016 and the software-defined datacenter, there are no previous enhancements. For more information, go to http://aka.ms/sroverview. Synchronous replication Synchronous replication guarantees that the application writes data to at least two locations at the same time before completion of the write operation. This replication is most suitable for missioncritical data because it requires network and storage investments and carries a risk of degraded application performance. Synchronous replication is suitable for both high availability (HA) and disaster recovery (DR) solutions. 46 CHAPTER 2 | Software-defined datacenter
As Figure 2-51 illustrates, when application writes occur on the source data copy (1), the originating storage does not acknowledge the I/O immediately. Instead, those data changes replicate to the remote destination copy (2) and log data is written (3). The remote site then returns an acknowledgment (4). Only then does the application receive the I/O acknowledgment (5). This ensures constant synchronization of the remote site with the source site, in effect extending storage I/O across the network. In the event of a source site failure, applications can failover to the remote site and resume their operations with assurance of zero data loss. Figure 2-51: Synchronous replication performed by Storage Replica Note In Figure 2-51, T indicates data flushed to the volume at the source site, and T1 indicates data flushed to the volume at the remote site. In all cases, logs always write through. Asynchronous replication In contrast to synchronous replication, asynchronous replication means that when the application writes data, that data replicates to the remote site without immediate acknowledgment guarantees (see Figure 2-52). This mode facilitates faster response time to the application as well as a DR solution that works geographically. With its higher-than-zero Recovery Point Objective (RPO), asynchronous replication is less suitable for HA solutions such as failover clusters because they are designed for continuous operation with redundancy and no loss of data.
