NAS– 为解决数据共享问题和优化文件（ File ）存储而产生的存储技术– 文件管理系统在存储设备端，是文件服务 +IP 的一种技术– 多应用于非结构化数据（文件）、 OLAP 、数据共享

SAN– 为解决 DAS 的问题而产生的存储技术– 是 DAS+ 网络的一种技术– 多应用于 OLTP 联机交易系统

iSCSI– 为解决 SAN 的成本、兼容性、不易部署和管理等问题而产生的技

术– 是 SAN+IP 的一种技术，所以 iSCSI 也叫 IP SAN

– 多应用于 PC 服务器平台

NAS 分类

Scale Out NAS

传统 NAS

Single Namespace. Ability to scale large numbers of clusters. Aggregation of storage for high utilization. Independent scale of GBs/sec of performance vs. PB’s of capacity. N+1 Availability

General purpose file storage. One or two node clusters. Usually allow capacity expansion only behind the clusters. Cost

effective, lower price points effectively addressing the small to midrange NAS market space

集中配置管理SONAS传统 NAS

“I loved my first filer. It was so easy to administrate. When we installed the 20th I started having problems managing them.”

Many enterprises now have hundreds

Each filer has to be individually administrated

Operation costs grow linear with the amount of filer

IBM Scale Out NAS is a super-scalable, scale out NAS cluster, centrally managed, centrally deployed

Integrated, automated tiered storage allows management of logical storage tiers instead of individual disks



自动分级SONAS传统 NAS

$$ $$ $$ $$

容量单独管理利用率低于 50% ，浪费比较

大所有文件在线 , 但 80% 的很

少被使用

集中容量管理利用率高于 80%

自动分级存储– 策略（ Policy ）驱动文件在不同级存

储中移动– 大容量存储，惰性文件自动迁移– 迁移粒度为“文件”级别



Web Content Store

Collaboration Data & General

File Storage

Energy & Geo- Sciences

High Performance Analytics

Digital Media

Hyper-scalable storage for large Web 2.0 stores and for other vendors looking to build their own Cloud/SaaS applications

General purpose file storage environments where clients are challenged with the manageability of current NAS systems

Energy exploration and geo-sciences require huge addressable namespaces and

very high performance.

Business applications such as financial services interested in cloud deployments

with single namespace

High performance, simplified management for widely varying use cases in digital

media environments.

Many environments needing easy-to-manage high performance, scalable storage.
