In a computer network where Windows 2000 Server is a server operating system, system administrators have an important task, which is to set disk quotas for clients accessing server resources, that is, limiting the number of volume spaces for them to access server resources at one time. The purpose of this is to prevent one client from over-occupying server and network resources, causing other clients to be unable to access the server and use the network. This article will introduce the relevant content on configuring server disk quotas.
How system administrators configure disk quotas
Disk quotas are not very important for ordinary Windows 2000 users, but this operation is extremely important for system administrators across the entire network. Because once there are many clients in the network and frequently access server resources and use the network, no matter how strong the server's computing power or how large the traffic the network can bear, it will be difficult to meet the needs of all users. Therefore, the system administrator must set disk quota for clients in the network. In Windows 2000, disk quotas control disk space usage according to volume tracking. System administrators can configure the following steps:
o Prevent further use of disk space and login events when the user exceeds the specified disk space limit.
o When the user exceeds the specified disk space alert level, log in to an event.
o When starting disk quota, two values can be set: disk quota limit and disk quota alert level. Quota limit specifies the amount of disk space that a user can use. The alert level specifies the point where the user approaches the quota limit. For example, set the user disk quota limit to 60MB and the disk quota alert level to 40MB. In this case, the user can store no more than 60MB of files in the volume. If the user stores more than 40MB of files in the volume, there will be a system event for the disk quota system to log in.
In addition, the system administrator can also specify that the user can exceed the quota limit. Because, when you don't want to deny users access to the volume, but want to track the disk space usage of each user, it is useful to start quotas and not limit disk space usage. You can also specify whether to log in to the event when the user exceeds the quota limit and disk quota alert level.
When the disk quota of the volume is started, the use of the volume will be automatically tracked for new users starting from that point. However, existing volume users will not be able to apply for disk quotas. By adding a new quota item in the Quota item window, you can apply for disk quotas for existing volume users. Quota can be started on local and remote volumes, but only volumes shared in the root of the volume and formatted as NTFS.
To support disk quotas, the disk volume must be in NTFS version 5.0. NTFS version 4.0 volumes will be automatically updated to NTFS version 5.0 format by Windows 2000 Setup. Furthermore, in order to manage the quota for volumes, the user must be a member of the administrator group on the computer where the drive resides.
Note: If the volume is not in NTFS format, or the user is not a member of the administrator group on the local computer, the Quota tab does not appear on the property page of the volume. In addition, file compression does not affect the accounting number of the volume. For example, if the user Larry is limited to 5MB of disk space, the user can only store 5MB of files, even if the files are compressed.
