Folder, Printer, and Share Management

Share Management

There are several ways to set up and manage shares. The WebUI provides screens for setting
up and managing shares. Additional methods include using a command line interface,
Windows Explorer, or NAS Management Console. This guide demonstrates using the WebUI
to set up and manage shares.
Note:
non-clustered configuration. This chapter discusses share setup for a non-clustered deployment. For
information on managing file shares and printers in a cluster, see the Cluster Administration
chapter.
As previously mentioned, the file sharing security model of the NAS device is based on the
NTFS file-level security model. Share security seamlessly integrates with file security. In
addition to discussing share management, this section discusses share security. See "Managing
File Level Permissions" earlier in this chapter for information on file security.
Shares management topics include:

Share Considerations

Planning the content, size, and distribution of shares on the NAS server can improve
performance, manageability, and ease of use.
The content of shares should be carefully chosen to avoid two common pitfalls: either having
too many shares of a very specific nature or of having very few shares of a generic nature. For
example, shares for general usage are easier to set up in the beginning, but can cause problems
later. Frequently, a better approach is to create separate shares with a specific purpose or group
of users in mind. However, creating too many shares also has its drawbacks. Take care to avoid
creating shares unnecessarily. For example, if it is sufficient to create a single share for user
home directories, create a "homes" share rather than creating separate shares for each user.
By keeping the number of shares and other resources low, the performance of the NAS server
is optimized. For example, instead of sharing out each individual user's home directory as its
own share, share out the top level directory and let the users map personal drives to their own
subdirectory.

Defining Access Control Lists

The Access Control List (ACL) contains the information that dictates which users and groups
have access to a share, as well as the type of access that is permitted. Each share on an NTFS
file system has one ACL with multiple associated user permissions. For example, an ACL can
define that User1 has read and write access to a share, User2 has read only access, and User3
has no access to the share. The ACL also includes group access information that applies to
every user in a configured group. ACLs are also referred to as permissions.
