VMware vSAN and SRM RPO and RTO

A question came up recently from a customer that went like this: “I am looking for an active/active configuration for disaster avoidance and disaster recovery with a recovery time objective of 0 minutes and a recovery point objective of 0 minutes. Is this something I can achieve with VMware vSAN and/or Site Recovery Manager (SRM)?” It is not the first time I have heard this question so it naturally made sense to write a blog article. Let’s dig in…

RTO and RPO Defined

Before we address possible solutions, let’s define the terms recovery time objective (RTO) and a recovery point objective (RPO) as they are often misused. Note that these terms contain the word “objective”, which means “something that one’s efforts or actions are intended to attain or accomplish; purpose; goal; target” according to Dictionary.com. In other words, these are the goals we are trying to achieve. I’ll give you an example: By stating that I have an RTO of two hours, that means the time required for recovery should take no more than two hours. The actual recovery time might be more or less time, but the target I am aiming for is two hours or less.

With the above information in mind, here are definitions from Wikipedia:
