66 C H A P T E R 3 | Storage Note In Windows Server 2016 Technical Preview, Storage Replica does not implement transitive replication, the so-called "A-B-C" topology (that is, synchronous replication from server A to server B, and then asynchronous replication from server B to server C). Storage Replica does not implement one-to-many replication. It is possible, for virtualized workloads only, to use Hyper-V Replica as the secondary asynchronous replication mechanism. This means configuring Hyper-V Replica on the source A volume and replicating to a server other than B, forming an "A-to-B + A-to-C" topology. Requirements The following are prerequisites for Storage Replica testing: Windows Server 2016 Technical Preview Datacenter Edition At least 4 GB of physical memory in each server and at least two cores AD DS (for SMB to use Kerberos) There is no need for schema updates, AD DS objects, certain AD DS functional levels, and so on. Network Greater than or equal to 1 Gbps network between servers Firewall ports open: SMB, WS-MAN Storage One NTFS/ReFS-formatted volume dedicated to replication per server/cluster site with at least 8 GB of free space GUID partition table (GPT) (not master boot record [MBR]) JBOD, iSCSI, local direct-attached storage (DAS) (non-cluster) SCSI or SATA, Storage Spaces Direct (cluster-to-cluster only), or Storage Array Network (SAN) Same sector sizes for the data volume drives and for the log volume drives No %SystemRoot% or page file located on replicated volumes or log volumes Recommendations The following are highly recommended for Storage Replica testing: Network Bandwidth: ≥10 Gbps network between servers Latency: ≤5 ms round-trip average for synchronous replication Storage Flash (solid-state drive [SSD]) disks for the log volume(s) with at least 8 GB of free space Note The final version of Storage Replica will contain additional scenarios and features, such as management by Microsoft Azure Site Recovery, and write-ordered consistency groups to ensure protection of applications that use multiple replicated volumes.
