Virtualization Storage Networking Identity and Access

Once Hyper-V Replica is enabled, VMs begin replication Affordable in-box business continuity anddisaster recovery Configurable replication frequencies of 30seconds, 5 minutes and 15 minutes Secure replication across network Agnostic of hardware on either site No need for other virtual machinereplication technologies Automatic handling of live migration Simple configuration and management Replicate Hyper ‑ V VMs from a Primary to a Replica site Once replicated, changes replicated on chosen frequency Upon site failure, VMs can be started on secondary site

Replication configured from primary to secondary Once a VM has been successfullyreplicated to the replica site, replicacan be replicated to a 3 rd location Chained Replication Extended Replica contents match theoriginal replication contents Extended Replica replication frequenciescan differ from original replica Useful for scenarios such as SMB ->Service Provider -> Service Provider DRSite Replicate to 3 rd Location for Extra Level of Resiliency Replication can be enabled on the 1 st replica to a 3 rd site

Expand Virtual SCSI Disks 1. Grow VHD & VHDX files whilst attachedto a running virtual machine 2. Then expand volume within the guest Shrink Virtual SCSI Disks 1. Reduce volume size inside the guest 2. Shrink the size of the VHDor VHDX file whilst the VM is running Online VHDX Resize provides VM storage flexibility

Allows an administrator to specify amaximum IOPS cap Takes into account incoming &outgoing IOPS Configurable on a VHDX by VHDXbasis for granular control whilst VM isrunning Prevents VMs from consuming allof the available I/O bandwidth tothe underlying physical resource Supports Dynamic, Fixed& Differencing Control allocation of Storage IOPS between VM Disks

Virtualization Storage Networking Identity and Access

The act of finding and removing duplication within data without compromising its fidelity or integrity Purpose: Store/Transfer less data How it works: Segment data into small variable sized chunks Identify and remove duplicate chunks Replace duplicate copies of each chunk with a reference to a single copy Compress chunks What is Deduplication?
