DRaaS Storage Policy

Overview

Data read and written to a virtual disk is defined as IoPS. IOPS (input/output operations per second) is a common unit of measurement in computing. It is used in performance testing of storage media such as hard disk drives (HDDs), solid-state drives (SSDs), and SANs.

Depending on the data read and written, we can estimate the percentage of reads and writes that a given environment will have.

The estimate was defined based on:

Environment	Read (%)	Write (%)
File Server	80	20
Maibox	50	50
Database	30	70
BigData	not applicable (multi-nodes)	Not applicable (multi-nodes)

The number of IoPS and the service class recommended for each environment:

We consider that read-write is doubled during a Disaster Recovery operation, in fact a clone of the virtual hard disk (VMDK) is being created which causes a doubling of IOPS.
