vSAN encryption was introduced in 6.6 to encrypt the data at both the drive levels i.e., cache and capacity disks that are part of a vSAN datastore. This is so easy to configure, do not require any in guest agents and supports hybrid, all flash , stretched cluster, dedup /

Object Space Reservation
If you are familiar with thin vs thick provisioning disk, this post will help you understand much easier about the OSR (Object Space Reservation). By default, virtual machine storage objects deployed on vSAN are thin provisioned. OSR is one of the storage policy, that specifies the percentage of the logical size
Disk Stripes in vSAN
Striping is not a new word in storage world. In vSan, Striping splits the data of a given object into multiple stripes (drives), also known as segments but not necessarily multiple hosts. Each stripe is accessed simultaneously, potentially increasing performance in hybrid configurations. vSAN allows for up to 12-way striping although 1

RVC Commands – Part 1
RVC (Ruby Virtual console) is an interactive command-line console user interface for VMware vSphere and Virtual Center. It is bundled with both VCSA and the Windows version of vCenter Server. RVC is becoming one of the primary tools for managing and troubleshooting Virtual SAN environments. Here are some of the RVC commands that

Power shell script to check dedup status
Deduplication and compression: How to check if vSan cluster has dedup enabled, though there are many ways to check it, I would show two ways here: From vCenter GUI: Login to vCenter using web client or HTML client , navigate to cluster > Manage > settings > Virtual San > General Deduplication and Compression
