拟态对象存储系统ECOS Mimic Object Storage System ECOS

介绍

Introduction

ECOS(Erasure Coding Object Storage)是一个基于多纠删码的具有拟态特性的分布式对象存储系统，并满足以下特性：

1、具有良好的扩展性、容错性以及可用性。兼容S3对象存储接口，能够在客户端完成文件的上传、更新、删除、下载等文件操作。

2、该系统支持纠删码(EC)模式，原生整合jerasure库中所有类型的纠删码，并支持嵌入BRS等满足jerasure标准编解码接口的第三方纠删码，通过其动态、异构、冗余等拟态特性保证了文件的完整性、不可篡改性以及可修复性。 

3、系统支持数据去重、数据校验、版本管理、小文件读写加速等功能。

4、数据服务器采用统一标准的存储接口与接口服务器相交互，做到底层存储构件可更换，支持本地文件系统、网络文件系统、对象存储系统等。

 

  ECOS (Erasure Coding Object Storage) is a distributed object storage system with mimic characteristics based on multiple erasure codes, and meets the following characteristics:

1. It has good scalability, fault tolerance and availability. Compatible with the S3 object storage interface, it can upload, update, delete, download and other file operations on the client side.

2. The system supports erasure code (EC) mode, natively integrates all types of erasure codes in the jerasure library, and supports embedding BRS and other third-party erasure codes that meet the jerasure standard codec interface. Mimic features such as redundancy ensure file integrity, immutability, and repairability.

3. The system supports functions such as data deduplication, data verification, version management, and small file read and write acceleration.

4. The data server uses a unified standard storage interface to interact with the interface server, so that the underlying storage components can be replaced, and support local file systems, network file systems, and object storage systems.

 

 

系统结构

System Structure

 

· 系统采用数据与存储接口分离架构；

· 由接口服务器、对象存储设备以及元数据服务器等三个核心组件构成；

· 系统采用模块化设计，可以分为负载均衡、接口服务、元数据管理、数据存储以及消息队列等五个模块；
