What is vSAN and VVol?

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.

What is VVol in VMware?

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 VVol Datastore?

vVols Objects A virtual datastore represents a storage container in vCenter Server and the vSphere Web Client. vVols are encapsulations of virtual machine files, virtual disks, and their derivatives. Virtual machine objects stored natively on the array storage containers.

How do I set up VVol?

Create a storage container and associated VVol datastore

1. Enter a name for the storage container. Use descriptive naming best practices.
2. Configure initiator and target secrets for CHAP.
3. Enter a name for the datastore.
4. Select one or more hosts for the datastore.
5. Select OK.

What are the benefits of vVols?

Advantages of Using vVols

• Simplified storage management for large virtual environments.
• Flexible and granular storage management on the VM level.
• Optimal resource utilization, dynamic adjustment in real-time.
• Avoidance of overprovisioning.
• Policy-based automated and centralized storage provisioning.

What is the meaning of VVol?

Virtual Volumes
VVOLs, which is short for Virtual Volumes, enables an administrator to apply a policy to a VM which defines the various performance and service-level agreement requirements, such as RAID level, replication or deduplication. The VM is then automatically placed on the storage array that fits those requirements.

How many VMs is a LUN?

Anywhere from four to 15 VMs per LUN is possible, but if you assign more than your infrastructure can handle, disk I/O could be saturated quickly. It’s also important to appropriately size your host resources to meet the expected performance of your VM storage subsystem.
