Create a new vSAN Storage Policy

Posted by

I wanted to cover real quick creating a custom storage policy on vSAN, which even on a VxRail is done in vCenter.

House keeping items:
Raid 1 mirror is where you write a complete replica of the object. This is the highest performance protection you can apply to an object. Since it is a complete replica it consumes 100% additional storage, IE, a 100GB VMDK will consume 200GB storage space.

Raid 5 is where you can tolerate 1 failure leveraging distributed parity. This is considered a capacity saver because it requires 33% overhead as compared to the 100% of Raid 1. If you have the same 100GB object it will only consume 133GB.

Raid 6 is where you can tolerate 2 failures leveraging distributed parity. This is also considered a capacity saver as it only adds 50% overhead as compared to the 100% of Raid 1. If you have the same 100GB object it will only consume 150GB.

Name it. I always recommend naming the storage policy by a particular app or what it will be used for.
This is where you will enter your FT method, erasure coding vs Raid1. You will also select add rule to add whether you want to be thin provisioned or thick provision.

That is how simple it is to create a new storage policy that can be applied to objects in your environment.
