Quick Start

1 Introduction

Acronis Storage is a cost-efficient software storage solution with cluster-level erasure coding that

allows optimal use of raw storage capacity at the highest level of resilience.

Acronis Storage is designed to run on commodity hardware, thus eliminating the dependence on

expensive, special-purpose hardware. Simplified deployment allows linear growth of system capacity

by adding extra drives to the existing nodes; or by adding new nodes via PXE or a special,

pre-configured ISO.

Acronis Storage offers simplified management and monitoring via a web console, with REST API for

integration into existing management environments.

This document describes how to deploy Acronis Storage for using with Acronis Backup Cloud.

2 Acronis Storage basics

Acronis Storage breaks the data stream that comes from Acronis Backup Cloud into 320MB

fragments. To ensure fault tolerance, each fragment is stored on multiple storage servers (nodes) as

a set of chunks with some redundancy.

Acronis Storage leverages the so-called N/K redundancy scheme: each fragment is split into K chunks,

then a certain number of additional (parity) chunks are added for redundancy, and then all of the

chunks are distributed among N servers (one chunk per server). The system can survive failure of any

(N-K) storage servers without data loss. The numbers N and K are determined by the storage system

configuration.

3 Acronis Storage redundancy modes

Acronis Storage supports three redundancy modes. You must choose the redundancy mode when

deploying Acronis Storage. For information about changing the redundancy mode at a later time,

refer to "Changing the redundancy mode (p. 16)".

Advanced mode (recommended)

This mode provides a scale-out storage platform with software-level redundancy.
