Create identical copies of your source VMs. Until needed, replicas remain in a powered-ff state and do not consume resources. VM replicas are available in your VMware vSphere client. If a disaster strikes, you can easily perform a failover, or power on the replica to have your VM running in basically no time. Our solution allows you to automate and orchestrate disaster recovery activities across multiple sites, reducing downtime to a minimum.
The feature can start both replication and failover jobs automatically , thus making the process of data center migration far less complicated. In addition to planned migration, the feature suits other purposes, including disaster avoidance and disaster recovery. Put differently, you can recover your source VM in a different environment , which enables not only VM data migration, but also long-term data archiving and recoverability testing.
To further simplify the data center migration process, our product offers two more features: Network Mapping and Re-IP. The first can help you make sure that the VM replicas are connected to the right network. Our flexible system of scheduling allows you to create a chain of jobs and test them before performing the actual migration. With the Calendar Dashboard , you can see all your past, current, and planned jobs in a calendar view, which can help you avoid overlaps and easily find free time slots for new jobs.

Storage vMotion, working in conjunction with Storage DRS can work to optimize your storage capacity across datastores. Using the datastore cluster construct in vSphere, the multiple datastores that are part of the datastore cluster can be monitored by Storage DRS so that once capacities reach a certain threshold, VMs are proactively moved to alleviate storage capacity pressure that may build on a single datastore.
With Storage DRS using Storage vMotion to utilize capacity as efficiently as possible, it allows more effectively making use of all available storage. This is difficult to do with manual efforts. Using the configured thresholds, it allows determining the amount of space utilized on a datastore before Storage vMotion operations kick into play.
Also, you can set the Minimum space utilization difference to configure which datastores should be considered as destinations for virtual machine migrations using Storage vMotion. This is the required difference in utilization between the destination and the source datastores. A look at the minimum space utilization difference for SDRS.
Another great benefit of performing a Storage vMotion is having the ability to perform a live disk transformation of a running virtual machine. The Storage vMotion process makes transforming disk types possible.
This 1 TB disk is provisioned and storage space is consumed immediately in your datastore. However, if the server was grossly overprovisioned on space and only a small amount of the 1 TB volume is used for storing actual data, a thin provisioned disk would allow reclaiming the space consumed with the thick provisioned disks. Changing the disk type when performing a Storage vMotion. The process is rather simple. Right-click a virtual machine in the vSphere inventory, and select Migrate.
This launches the Migrate wizard. On the first Select a migration type screen, you have three choices:. The second and third options involve using Storage vMotion.
You can choose to change only the storage, or change both the storage and the host housing the virtual machine. On the Select storage screen, choose the virtual disk format and the target datastore for the Storage vMotion. Choose the virtual disk format and target datastore. Finally, on the Ready to complete screen, review the Storage vMotion operation to be performed and click Finish to begin the process.
Completing the Storage vMotion wizard. This can easily be achieved with PowerCLI. The below recorded capture is for the process to perform a Storage vMotion of a particular virtual machine and changing the type of disk as it is migrated to a different datastore.
You can use the output of the code capture to automate further processes such as Storage vMotion. Storage vMotion provides powerful capabilities to the VMware vSphere virtualized environment. Fifth, since the use of Storage vMotion is seldom automated, its use requires administrator time, something that the data center may not be able to afford.
It also requires planning and real-time decision making. The administrator has to make a very quick analysis of the situation causing the problem, and then decide which VMs to move and when to do it. The risk of error given this kind of pressure is high. Finally, Storage vMotion almost encourages storage sprawl.
It is always easier to manage one component instead of multiple components, and storage is no different. But there is also a legitimate need to store different types of data on different storage media. For most data centers, a consolidated storage solution will be a storage system that has both flash and hard disk drives.
Managing the movement of data between these tiers should ideally be done by something like VVOLS or the storage systems own data movement intelligence. Preferably the system will leverage both. A consolidated storage system should provide a quality of service QoS functionality that can either integrate with VVOLS and Storage vMotion or provide the functionality independently for times that it is hosting non-VMware or non-virtualized workloads.
It is key for the storage system to move data within the storage system itself instead of across storage systems. As a default the storage system should provide an automated movement of the most active data to the higher performance flash tier. In many storage systems this is accomplished via a physical LUN migration between tiers.
The result of this style of automated data movement, combined with an administrator driven QoS capability eliminates the need for Storage vMotion and all the pains associated with it. The time that the administrator spends tuning storage performance is also reduced. Essentially once performance parameters are set, it becomes the responsibility of the storage system to make sure they are met. Learn how your comment data is processed. Email Address.

Two Storage VMotion DMotion tasks failed with an error : To resolve this, first verify it is the same problem by checking the files in the old and new directories. The old directory should have only VMDK files : The New Lun will look like a normal VM directory with vmx, vmsd, nvram and vmdk files: At this point you simply need to edit the vmx file to point to the new location and the VM should launch.
