Three key elements of JetStream DR software need to be deployed before it can be operated:

    • Management Server Virtual Appliance (MSA): The MSA is used to install and configure host components on the compute cluster and then to administer JetStream DR software. The MSA is deployed during initial installation of JetStream DR software.
    • Host Components (IOFilter packages): VMware IOFilters are deployed to each vSphere host and are located in the data path between protected VMs and their virtual disks. They intercept data written to virtual disks and replicate it to object storage for protection via the DRVA. IOFilters also monitor relevant events, such as vMotion, Storage vMotion, snapshots, etc. IOFilters get deployed to hosts of clusters that contain VMs protected by JetStream DR software.
    • DR Virtual Appliance (DRVA): The DRVA is an appliance that manages data path DR components responsible for the transfer of protected data to the object store. Multiple DRVAs can be used concurrently for better scalability. Each DRVA has one or more replication log volumes attached as an iSCSI LUN or as a low-latency VDISK. DRVA volumes contain replication logs of protected data and repositories for persistent metadata. DRVAs can be deployed after the software has been installed and configured.
