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
