And it is only available on all-flash disk groups, on-disk format version 3.0 or later. VMware vSAN deduplication occurs when cold data is sent to the capacity tier (after the write acknowledgments are sent to the VM). When the data is no longer active, the cold data will be destaged to the capacity tier at a time and frequency determined by the vSAN. To provide a higher level of storage performance, active VM data is first written to the write buffer with write acknowledgements sent immediately to the guest. VSAN is a two-tier distributed storage system made of a cache tier and a capacity tier. #Duplicate windows vmware license#This means that you must have a valid license to enable vSAN deduplication and compression on your cluster. VMware data deduplication is not a function of ESXi itself, but provided by vSAN, a software-defined component that is fully integrated with vSphere. #Duplicate windows vmware how to#In this article I will introduce how VMware data deduplication works, and the detailed steps on how to enable deduplication and compression on vSAN. Both of them can effectively reduce the amount of physical storage required to store the data. Deduplication removes redundant data blocks, while compression removes additional redundant data from each block. In VMware environments, it is often used in combination with data compression. Switch the CD/DVD drive to client device, disconnect it, and convert the VM to a template.When backing up VMware ESXi VMs, if you have limited storage space or just want to save on VM storage costs, you definitely need to know about VMware data deduplication technique.ĭata deduplication is a simple and practical space efficiency feature.Reduce the VM's CPU count and memory resources to the minimum.Install all baseline applications you might want to include in your template.

Point to the Windows Server ISO file location. Make sure you select Microsoft Windows Server 2016 or later (64-bit) as the guest OS. Learn how to deploy and install Windows Server and convert VM to a template. Make sure you have VMware vSphere version 6.5 or above. Note that the ISO file can also be used locally. It's recommended to upload the Windows Server ISO file to a vSphere datastore or to vCenter content library for faster development.Make sure you have the latest Windows Server ISO file downloaded. This guide assumes that you have some familiarity with VMware vSphere and know how to install Windows Server. ![]()
