vSAN encryption

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

Failures to Tolerate (FTT)

FTT is familiar name when working on vSAN and I consider this as most important policy when designing a vSan cluster. In this post, I am going to quickly walk you through the use of this policy and how it works.. The Number of Failures to Tolerate capability addresses the key

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

vSan force provisioning

I would like to brief here about one of the rules in vSan storage policy i.e., Force Provisioning, it may sound very easy, but at times can put the environment in trouble. Force provisioning is the rule which can be selected when creating a new storage policy as shown below: I

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
