EMC单个LUN容量问题

客户有一个需要存放高速上每个摄像头的视频的服务器。算是一个FTP吧,每个点的视频会上传到这台服务器上,但是客户需求分区需要到达30TB,就是单LUN达到30TB,我想问下,VNX系列中有什么型号的可以达到该需求?

FTP数据汇聚一般用Pool LUN(Thin LUN的存储利用率高),上一代VNX (5100/5300/5500/5700/7500)支持的最大Pool LUN是16TB,而如楼上所说,新一代VNX就可以支持256TB的Pool LUN了。

不过你是要将Pool LUN挂载某台主机上然后主机上开启FTP服务,还是直接用VNX的FTP?VNX的File System有16TB的限制。

VNX2,全系列的池lun都支持256TB。

如果是MetaLUN,根据知识库emc111629,"The maximum metaLUN size is 16 EB (where EB is an exabyte, which is a billion gigabytes)"。因此只要磁盘数量足够,存储端LUN的大小限制远远超过了要求。MetaLUN需要使用tranditional LUN。


Pool Lun:5200,5400,5600,5800,7600,8000支持的最大pool LUN都是256 TB。

You can have a look at NMFS (File system that contains the nested mount root file system and component file systems) features, a kind of FS. It is simpler to use than FTP. An NMFS allows you to manage a collection of component file systems as a single file system. CIFS and NFS clients see component file systems as a single share or single export. File system capacity is managed independently for each component file system. This means that you can increase the total capacity of the NMFS by extending an existing component file system or by adding new component file systems.

The number of NMFS or component file systems is limited only to the number of file systems allowed on a Data Mover. That means adding component file systems to NMFS is equal to the max FS supported by per Data Mover (Which is 256 TB, 16*16=256 TB), total can be 16 FS.

This will give you a better manageability. The other facts to look into are backup (if backup is required large FS may take longer), need to check the OS limitations if any, on where this FTP (NMFS) will be running. All VNX systems support it, (which are Unified or File Only).
