What is a virtual datastore in VMware?
A Virtual Datastore represents a storage container in a vCenter Server instance and the vSphere Client. A vSphere Virtual Datastore represents a one-to-one mapping to the storage system’s storage container. The storage container (or Virtual Datastore) represents a logical pool where individual vVolsVMDKs are created.
What is a VVols storage container?
A vVols Storage Container is a logical abstraction on to which vVols are mapped and stored. Storage containers are setup at the array level and associated with array capabilities. vSphere will map the Sstorage Container to Virtual Datastore and provide applicable datastore level functionality.
What is VVol storage?
vVols defines a new virtual disk container (Virtual Volume) that is independent of the underlying physical storage representation. This virtual disk becomes the primary unit of data management, eliminating pre-allocated LUNs/Volumes.
What is the difference between VMFS and VVol?
VMware vVols is the low-level storage for virtual machines that supports operations on the storage array level, similarly to traditional LUNs used to create datastores. Instead of using the traditional VMFS file system, a storage array defines how to provide access and organize data for VMs using the storage array.
What is VVol in netapp?
VVOLS are software-defined storage that simplify storage management. A VVOL tells the vCenter Server what the storage can do; however, it does not create objects that make up the storage. When you use VVOLs, you can manage your storage at the virtual machine level instead of the datastore level.
What does VVol stand for?
The concept of VMware vSphere Virtual Volumes (VVol) holds a lot of promise.
What is a VMFS datastore?
VMFS deposits files in a storage container called a datastore, a separate filesystem that runs on top of a volume. Datastores reside on a block-based device such as iSCSI. Virtual machine disks (VMDKs) are housed in the datastore.
What is vSAN and VVol?
Two of these storage technologies are Virtual Volumes (vVOLs) and Virtual SAN (vSAN). Both offer exciting capabilities and opportunities for businesses to configure, manage, and scale their storage. While both vVOLs and vSAN have some similarities between them, they are different storage technologies.
How do I create a VVol?
Steps. From the Navigator view in vCenter, right-click a storage cluster and select Storage > Datastores > New Datastore. In the New Datastore dialog box, select VVol as the type of datastore to create. Provide a name for the datastore in the Datastore name field.
How do I set up VVol?
Using the management GUINavigate to Settings > System > VMware Virtual Volumes (vVols).Select On to enable Virtual Volumes. ... Create a child pool. ... Create Storage Credentials for vCenter. ... Complete the remaining steps in VMware vCenter to finish the vVol configuration: ... In the management GUI, create a new ESXi host server.
What is a PE Lun?
PE LUNs are only used by virtual volumes (VVols) in VMware software-defined storage. VVols provide storage space for VMs. A PE LUN is used as an I/O distributor to simplify the connection between a VM and a VVol. I/Os from a VM are sent to the VVol through a PE LUN.
Is VVol object based storage?
Though, since VVol datastores are not physical objects or file systems, they do not have the same constraints that a file system might have, like total size. A VVol datastore can be up to the zettabytes in size if needed.
What are VMDK files in VMware?
VMware Virtual Machine Disk File (VMDK) is a format specification for virtual machine (VM) files. A file with a . VMDK file extension is essentially a complete and independent virtual machine.
What is vSAN in VMware?
VMware vSAN is a software-defined, enterprise storage solution that supports hyper-converged infrastructure (HCI) systems. vSAN is fully integrated with VMware vSphere, as a distributed layer of software within the ESXi hypervisor.
What is difference between VMFS and NFS?
Like we stated above, VMFS is a block level file system, while NFS is a file level file system. When creating a VMFS Datastore, the VMFS file system is created by the vSphere, while the NFS file system is on Storage side and is only mounted has a shared folder on the vSphere.
What is VMFS and Vmfsl?
VMFS is designed to be cluster aware file system and it is optimised for concurrent cluster operations like metadata operations towards storage solutions. VMFS-L came into picture with vSAN bcoz vSAN works with object storage using locally attached storage. So VMFS-L is optimised for object based storage.
What is VMFS volumes?
VMware® VMFS Volume Management The VMware Virtual Machine File System (VMFS) is a powerful automated file system that simplifies storage management for virtual machines. VMFS also serves as a cluster volume manager to ease the management of shared storage resources within a cluster of VMware ESX hosts.
What is the difference between VMFS5 and VMFS6?
You cannot upgrade the VMFS5 datastore to VMFS6. Below are the some of the new features of VMFS 6: Automatic Space Reclamation (which allows storage arrays to reclaim deleted or unmapped disk blocks from a VMFS datastore so it can be used elsewhere) Support for 4K Native Drives in 512e mode.
What is a VVol Datastore?
I have been traveling around lately talking about VVols and one of the most commonly misunderstood objects is the VVol datastore. What is it? What does capacity mean on it? Why does it even exist?
How does a VVol datastore track capacity?
VVol datastores are array-aware. How much space is used in a VVol datastore is entirely up to the storage array to decide. With VMFS, for instance, how much is used is the summation of the allocated size of the virtual disks on it (plus snapshots and other files). If a virtual disk is thick, the whole size of the virtual disk counts towards the used amount. If a virtual disk is thin, just how much has been written to it is what counts. With VVols, it is entirely up to the array to decide how much space a virtual disk uses. Let me give you an example:
What would happen if there was no VVol endpoint?
Instead the protocol endpoint acts a “switch” the VVol datastore is associated with it and all I/O goes to the PE and the PE routes the I/O to the appropriate VVol on that array,
What is a VM config?
It is a collection of VMs. Every VM has a config VVol and and each config VVol is a mini-file system that has pointers to VVols and VM configuration information. When a virtual disk is created on a VM in a VVol datastore, a vmdk file is created in that config VVol that points the VM to the VVol (the volume) on the array. See more information on config VVols here:
How much can a VVol datastore provision?
A VVol datastore has a capacity and this capacity limits how much a VMware admin can provision using it. If the VVol datastore is 40 TB , you can provision up to 40 TB. This is also no different than VMFS or NFS. Though, since VVol datastores are not physical objects or file systems, they do not have the same constraints that a file system might have, like total size. A VVol datastore can be up to the zettabytes in size if needed. So there is no practical limit, like the 64 TB limit that VMFS has. So the actual limit of a VVol datastore is really up to the storage vendor.
What is the great thing about VVols?
These are all good questions. The great thing about VVols is that very little changes in how the VMware user interacts with vSphere. But at the same time, what actual happens is VERY different. So let’s work through this.
Does the virtual disk size limit change?
Note that the virtual disk size limit does not change. You can see that when you try to mount a VVol datastore:
What is a vVols datastore?
A vVols datastore represents a storage container in vCenter Server and the vSphere Client.
Is vVols formatted?
The vVols datastores are not formatted in a traditional way like, for example, VMFS datastores. You must still create them because all vSphere functionalities, including FT, HA, DRS, and so on, require the datastore construct to function properly. You use the datastore creation wizard in the vSphere Client to map a storage container ...
Can vVols be used with VMFS?
You can use the vVols datastores with traditional VMFS and NFS datastores and with vSAN.
What is vVols storage container?
2. Storage Containers (SC): vVols uses non-traditional storage; i.e., a storage container, which is a pool of raw storage capacity or a set of storage capabilities. It is created and managed on the disk array side and is intended for logical grouping and isolation of virtual machines.
What is a vVol?
vVols are an addition to the traditional NFS and VMFS. For each virtual machine and its files, a separate vVol is created, and virtual disks can be managed independently. You can create vVol datastores based on one or more base storage pools.
What is virtual data storage?
4. Virtual data storage is a storage container similar to VMFS volumes in vCenter Server and vSphere Web Client. The disk array fully controls all storage expansion and upgrade operations.
What is VMFS recovery?

What is vVols in IT?
vVols is an industry-wide initiative that will allow IT organizations to leverage the unique capabilities of their current storage investments and transition without disruption to a simpler and more efficient operational model. IT organizations can also manage heterogeneous storage using a common control plane.
What is Virtual Volumes (vVols)?
vVols uniquely shares a common storage operational model with vSAN, the market leading hyperconverged infrastructure (HCI) solution. Both solutions use storage policy-based management (SPBM) to eliminate storage provisioning, and use descriptive policies at the VM or VMDK level that can be applied or changed in minutes. SPBM accelerates storage operations and reduces the need for specialized skills for storage infrastructure.
Why is VVols important?
With vVols, it is much simpler to deliver and enable the right storage service levels according to the specific requirements of individual VMs. By having finer control over storage resources and data services down to the VM level, the VI administrator can create exact combinations and precisely deliver storage service levels. Over-provisioning is eliminated because each VM will consume the exact resources needed – nothing less, nothing more.
What is a virtual datastore?
A Virtual Datastore represents a storage container in a vCenter Server instance and the vSphere Client. A vSphere Virtual Datastore represents a one-to-one mapping to the storage system’s storage container.
What is VMware vVols?
vSphere Virtual Volumes or vVols implements the core tenants of the VMware Software-Defined Storage vision to enable a fundamentally more efficient operational model for external storage in virtualized environments, centering it on the application instead of the physical infrastructure.
What is a vendor provider?
The vendor provider, also known as the VASA provider, is a storage-side software component that acts as a storage awareness service for vSphere and mediates out-of-band communication between vCenter Server and vSphere hosts on one side and a storage system on the other. Storage vendors exclusively develop VASA providers.
Why use a network time server in VMware?
VMware recommends the use of a Network Time Server for all the systems in order to maintain accurate timekeeping.
What is a vSphere admin?
A vSphere admin maps the storage capabilities presented to vSphere and organizes them into a set of rules that are designed to capture the quality of service requirements for virtual machines and its application. These rules are saved to vSphere in the form of a VM Storage Policy.
Why isn't my virtual datastore working?
This is because a Virtual Datastore is already mapped to a storage container. In order to mount the Virtual Datastore use the Mounting Virtual Datastore to Multiple Hosts procedure
What protocol is used to synchronize storage?
Synchronize the time of all storage components with vCenter Server and all vSphere hosts. It is recommended to utilize Network Time Protocol (NTP) for synchronization.
What is vvols in VMware?
VMware vSphere Virtual Volumes (vVOLs) was one of the new features that were added back in the vSphere 6.0 release. Recently with vSphere 6.5, a few enhancements were made to the vVOLs and I am seeing quite a few customers use this in their production environment.
How many types of virtual volumes are there?
There are five different types of Virtual Volumes object types and each of them maps to a different and specific virtual machine file.
Why should I use VMware vSphere Virtual Volumes?
Following are the benefits that one can get when using Virtual Volumes compared to legacy storage technologies:
What are the different types of Virtual Volumes Objects?
As discussed earlier, Virtual Volumes are a new type of virtual machine objects, which are created and stored natively on the storage array.
What is a vendor provider?
Vendor Providers (VP), also referred to as VASA Provider, is a storage-side software component (Plug-In) that act as a storage awareness service for vSphere. Storage vendors exclusively develop vendor providers.
How many storage containers are needed for a storage array?
There needs to be at least one Storage Container on the storage array. More SCs can be created on the design and implementation process.
What is Finer Control of Storage Class of Service?
Finer control of storage class of service: Match VM storage requirements exactly as needed with a class of service delivered per VM.
What is vVols storage?
vVols are a new model for provisioning, managing, and accessing virtual disks for vSphere VMs. Using Storage Policy-Based Management (SPBM), VMs are provisioned with storage from vVols based arrays or servers through the mediation of a VASA Provider (VP) which provides an out-of-band interface for managing vVols based storage. vVols are designed to work equally over SCSI (FC, iSCSI, or FCoE) or NAS protocols. Storage arrays or servers are designed to manage all aspects of vVols storage and vSphere hosts have no direct access to a vVols storage. Instead, hosts access vVols through an intermediate point in the data path, the so-called "I/O Multiplexer" or "Protocol Endpoint" (PE) which is a SCSI target in the case of block-based vVols storage and an NFS mount point for NAS-based vVols storage.
Where are vVol files located?
There are no "files". vVols reside natively on the storage array and are referenced by the VM as it powers on. There is metadata information linking a vVol to a particular VM, so a management UI could be created for the vVols of a VM.
How many vVols can you have?
Those limits are entirely determined by the array vendor's implementation. vVols implementation does not impose any particular limits. You can have up to 64,000 vVols per host and a vVols datastore can be up to a zettabyte.
How many vVols per VM?
There is typically a minimum of 3 vVols per VM. The maximum would depend on how many virtual disks and snapshots reside on the VM,
What is a VASA provider?
The VASA Provider or VP is the endpoint of the out-of-band management connection. The VP is used to set up access to a vVol, communicate with VC and with ESX hosts as vVols are used, and ultimately release vVols. In addition, VASA commands to the VP can be used to snapshot vVols , revert a vVol to a previously created snapshot, as well as change the storage profile of an existing vVol .
Where is vmdk stored?
The .vmdk file (the virtual disk descriptor file) is stored in the config vVol with the other VM description information (vmx file, log files, etc.). The vVol object takes the place of the flat file. The vmdk file has the ID of the vVol.
Can SRM manage vVols?
SRM can manage vVols that are using vSphere Replication or vVols array-based replication as of vSphere 7. Array-based replication is supported in vVols however configuration and execution of failover activities can be managed with public APIs or PowerCLI 6.5.
