Today’s File Storage

2-2 CLI Storage-Management Guide

Balancing the capacity between these islands means moving popular files between

file servers, but this can be difficult. Each client connects to back-end storage

statically, through an IP address or FQDN, and chooses from a list of shares and paths

that reside at that storage device. Moving files from one storage device to another

means updating the client-side view of IP addresses, share names, and/or file paths.

File storage is therefore static and expensive to manage.

Adaptive Resource Switching solves these expensive problems by creating a virtual

view of back-end storage for the front-end clients. Clients connect to all back-end

storage through a virtual directory structure called a namespace volume. The storage

devices are hidden behind the volume, making it possible to balance capacity and load

at the back end without affecting any client-access on the front-end. An Adaptive

Resource Switch can thereby

• optimize the file-storage infrastructure,

• adapt file storage to client demands, and

• control management costs.
