What are transport modes in VMware?

A VMware Backup Host can access Virtual Machine data from datastores using four different methods – SAN, LAN(NBD), HotAdd, NBDSSL. These methods are referred to as VMware Transport modes.

How do I add an existing VM to ESXi?

How to Import Virtual Machines Into ESXi Using the vSphere Client

  1. In the vSphere client, click on the server.
  2. Click on the summary tab.
  3. Right click on datastore -> Browse Datastore.
  4. Use the icon with the up arrow in front of some disks (Upload files to this datastore)
  5. Upload the folder or files that you require.

What is NBD transport mode?

Network Block Device (NBD) transport mode, also referred to as LAN transport mode, uses the Network File Copy (NFC) protocol to communicate. Various VDDK and VCB operations use one connection for each virtual disk that it accesses on each ESX/ESXi Server host when using NBD.

How do I add a VM to my host?


  1. In the vSphere Client, navigate to a data center or folder within a data center.
  2. Right-click the data center or folder and select Add Host.
  3. Enter the IP address or the name of the host and click Next.
  4. Enter administrator credentials and click Next.
  5. Review the host summary and click Next.

How do I add a VM to VMware inventory?

Right-click the . vmx file and click Add to inventory. The Add to Inventory wizard opens. Continue to follow the wizard to add the virtual machine.

What is NBD in backup?

NBD (network block device) is the most universal of the VDDK transport modes. It does not require dedicated backup proxy VMs like HotAdd, and works on all datastore types, not just SAN. Sections below give tips for improving NFC (network file copy) performance for NBD backups.

How do I add storage to ESXi?

In the vSphere client, complete the following steps:

  1. Select the host.
  2. Click the Configuration tab.
  3. Click the Storage section.
  4. Click Add Storage.
  5. Follow the prompts to add the new disk or LUN.

How do I map a LUN to ESXi host?

Presenting a LUN to a VMware ESXi host

  1. From the Actions list, select LUN, then select Present LUN to present a logical unit to an ESXi host.
  2. Select the Storage System.
  3. Select the Logical Unit ID.
  4. Click Next.
  5. Select ESXi Cluster or Hosts.
  6. Click Next.
  7. Review the Summary window.
  8. Click Submit.

What is VMware Vddk?

The Virtual Disk Development Kit (VDDK) is a collection of C/C++ libraries, code samples, utilities, and documentation to help you create and access VMware virtual disk storage.

What is VMware hotadd transport mode?

HotAdd: When running VMware Backup Host on a Virtual Machine, vStorage APIs can take advantage of the SCSI Hot-add capability of the ESX/ESXi server to attach the VMDKs of a Virtual Machine being backed up to the VMware Backup Host. This is referred to as HotAdd transport mode.

Can ESX/ESXi host use local storage?

The ESX/ESXi host can use any storage device, including local storage or NAS. The VMware Backup server could be a virtual machine, so you can use a resource pool and scheduling capabilities of VMware vSphere to minimize the performance impact of backup.

What are the different transport modes in a VMware backup host?

A VMware Backup Host can access Virtual Machine data from datastores using four different methods – SAN, LAN (NBD), HotAdd, NBDSSL. These methods are referred to as VMware Transport modes.

What is San transport mode in VMware?

SAN: The SAN transport mode requires the VMware Backup Host to reside on a physical machine with access to Fibre Channel or iSCSI SAN containing the virtual disks to be accessed. This is an efficient data path because no data needs to be transferred through the production ESX/ESXi host.
