Does vMotion require shared storage?
Does vMotion require shared storage?
vMotion does not require environments with shared storage. This is useful for performing cross-cluster migrations, when the target cluster machines might not have access to the storage of the source cluster. Processes that are working on the virtual machine continue to run during the migration with vMotion.
Does storage vMotion use the vMotion network?
Network is not use during storage vMotion. So, it the same situation like in Scenario 1.
What is the difference between vMotion and storage vMotion?
Summary: VMware vMotion vs vMotion Storage VMware vMotion allows you to move VMs from one ESX server to another without downtime for users, while the data store can be mounted on both the source and target hosts.
What network connections must be in place for vMotion?
at least a Gigabit Ethernet network interface card with a VMkernel port enabled for vMotion on each ESXi host is required. identically named virtual machine port groups connected to the same network. All port groups to which the VM is attached must exist on both ESXi hosts.
Is vMotion possible between clusters?
Yes, you can migrate VM’s between vSphere clusters (even between different versions) as long as below conditions are met: vSphere clusters must be managed by single vCenter server. vSphere clusters must be within single DataCenter object in vCenter server.
Why vMotion is required?
vMotion enables IT departments to migrate individual VMs from a private data center to a public cloud as needed. Be sure the cloud provider can match both the hardware and software requirements for compatibility. Alternatively, migrating powered-off VMs reduces the compatibility requirements.
Does vMotion require jumbo frames?
Note: Jumbo frames for vMotion is both supported and recommended as per this KB. Specifically the line “Use of Jumbo Frames is recommended for best vMotion performance.”
Why is vMotion using the management network instead of the vMotion network?
If the virtual machine is stored on a local or non-shared datastore vMotion is using the vMotion network to transfer the data to the destination datastore. The reason why vMotion uses separate networks is that the vMotion network is reserved for data migration of performance-related content.
What is storage vMotion in VMware?
Storage vMotion is a component of VMware vSphere that allows the live migration of a running virtual machine’s (VM) file system from one storage system to another, with no downtime for the VM or service disruption for end users. This migration occurs while maintaining data integrity.
Which port used for vMotion?
ESXi 5. x
| Port | Protocol | Purpose |
|---|---|---|
| 8000 | TCP | Requests from vMotion |
| 8000 | TCP | Requests from vMotion |
| 8100 | TCP/UDP | Traffic between hosts for vSphere Fault Tolerance (FT) |
| 8182 | TCP/UDP | Traffic between hosts for vSphere High Availability (vSphere HA) |
How do I vMotion a VM?
Migrate to a different host
- Log in to VMware vSphere client console.
- Right-click the virtual machine and select Migrate.
- Go to Migrate Virtual Machine.
- Select the Change host as the Migration Type and click Next.
- Select the destination host and click Next.
- Select the vMotion priority and click Next.
Does vMotion use the vMotion network?
If the virtual machine is stored on a local or non-shared datastore vMotion is using the vMotion network to transfer the data to the destination datastore. When monitoring the VMkernel NICs, some traffic can be seen following over the management NIC instead of the VMkernel NIC enabled for vMotion.
What happens to vmdk files when vMotion is connected to vMotion?
The files in the VMDK directory are copied across the network of the first VMkernel NIC. If the management network (actually the first VMkernel NIC) and the vMotion network share the same subnet (same IP-range) vMotion sends traffic across the network attached to first VMkernel NIC.
What are the best practices for configuring network resources for vMotion?
Consider certain best practices for configuring the network resources for vMotion on an ESXi host. Provide the required bandwidth in one of the following ways: Provision at least one additional physical NIC as a failover NIC. Use jumbo frames for best vMotion performance.
Why is there traffic over the management Nic instead of vMotion?
When monitoring the VMkernel NICs, some traffic can be seen following over the management NIC instead of the VMkernel NIC enabled for vMotion. When migrating a virtual machine, vMotion determines hot data and cold data.
