MOVE DATA COMPLETELY, RELIABLY, AND WITHOUT INTERRUPTION.
JetStream Migrate is a lightweight application for live migration of virtual machines from any on-premises VMware environment to any VMware environment in the cloud. During data replication to the cloud, VMs continue to run without interruption, and all standard cluster functions (vMotion, etc.) are supported.
The software is deployed in the on-premises data center from a VIB, and its cluster-wide deployment is managed directly by vSphere. Once migration is complete, the software is seamlessly uninstalled by vSphere. The migration process is managed through the vCenter GUI, through a JetStream plug-in to the on-premises vCenter Server.
The key to an efficient, painless migration to the cloud is to move workload data completely, reliably and without interruption to applications while they’re running.
Enable virtual machines to move from on-premises systems to cloud hosts with the ability to migrate of data reliably over any distance. Data can be transported over a long-distance network connection as well as on a portable data transport device.
Fully integrated with VMware vSphere through the vSphere APIs for IO Filtering (VAIO), it works seamlessly with any storage – VMFS, NFS and Virtual SAN are all fully supported.
Move workload data to the cloud with minimal disruption to running applications, storage systems, and disaster recovery platforms.
Migration Time Estimation: JetStream Migrate runs in “observation mode” prior to migration, measuring network throughput and monitoring storage I/O, in order to accurately predict the time required for data replication for individual VMs or groups of VMs.
Dual Backpressure Controls: The administrator can throttle the replication rate to avoid impacting application performance on premises. Similarly, VM storage I/O can be controlled on-premises, to avoid overwhelming a slow replication network.
- Live Migration with Data Shipped on a Device: JetStream Migrate is the only solution for VM live migration that provides the option of copying data to a physical device for shipment, and sending only newly written data over the network.
- Fault-Tolerant Data Replication: If data replication is interrupted (due to Network issues, host failure, or any other reason) it can resume replication from the point of interruption, rather than starting replication from the beginning.
Orchestration & Automation: VMs can be migrated individually, automatically migrating to the destination and starting up one after the other. Interdependent VMs may be migrated and started as a group, with administrative control of the change-over.
Statistics & Notifications: The GUI presents current and historical statistics visually, and data can be exported for reporting. The administrator can configure notifications for incidents such as interruptions or task completions.
- Support for All Datastore Types: JetStream Migrate can move VMs and their data from any VMware-supported storage: SAN, NAS, Virtual Volumes, Virtual SAN or other HCI.
JetStream Migrate is the first data replication solution for cloud migration to run as an IO filter in the VMware vSphere hypervisor. This enables the software to integrate seamlessly with the on-premises VMware environment with no disruption to existing storage, backup or DR solutions. The software installs as a VIB and is managed through vCenter (Linked Mode). Standard vSphere functions (vMotion, DRS, etc.) are available while data replication is under way; and vSphere-native data encryption and compression, network bandwidth optimization are also supported.
“When you can remove the friction of VM migration from the customer onboarding process, you’ve given a massive boost to a cloud provider’s bottom line”

JetStream Migrate Product Architecture
Mouse over each of the four components below for a more detailed description.
The Management Server virtual appliance is a vCenter plugin that is used to manage and orchestrate migration. Regardless if data will migrate over a network or via physical media, the administrator manages all migration processes through a GUI connected to the Management Server.
The Migration Estimator is a utility that helps administrators predict the time and network bandwidth required to move an application’s data to the cloud. It not only takes into account the amount of data to be transferred, but the actual network bandwidth available for the transfer and the amount of data that will change during the transfer, requiring additional “foreground” data transfer.
The Data Replicator is responsible for moving data to its destination with minimal disruption to the application as it continues to operate on-premises. The Data Replicator is integrated with vSphere through an IO Filter, based on the VAIO API. It combines two replication processes (foreground and background) to copy data to the destination while the VM and its applications continue to run uninterrupted.
The Data Transporter moves data to its destination via a physical device. If the amount of data for migration is exceedingly large, moving it over a network may be impractical, if not impossible -- transferring it using a physical device might be the only feasible option. Even when the Data Transporter is used to move data, the VM and its applications continue to run uninterrupted at the source.
How it Works
How it Works
Prior to data replication, the migration network bandwidth is measured and storage IO activity is monitored, to provide an estimate of the time and bandwidth required for data replication and recommended data transfer method.
Background Replication (Network)
Data is read from the VDISK at the source and copied to the destination over the network.
Background Replication (Device)
If network performance is inadequate, data can be transferred from the source to the destination via physical media.
Data write operations take place while migration is under way and data is reconciled at the destination.
