The quota of Win2003 Server of magnetic disc uncovers is dense

The quota of Win2003 The quota management of magnetic disc of Microsoft Windows is to begin to have got since the system of Windows 2000, it is very important that it manages for the space of magnetic disc with valuable server. This text will introduce the magnetic disc of the system of Windows Server 2003 to all to manage function.

One and Windows Server 2003

In the Windows systematic quota of Server 2003

1. Quota

The quota monitor of magnetic disc the roll of personal user use condition, the therefore every cash in on of user for the space of magnetic disc will not influence same a volume of go up the quota of magnetic disc of other users. For instance, if the quota restriction of roll F is 500MB, , user has preserved the file of 500 MB in roll F, so after this user must first delete or move some existing files from it, may just write in other datas to roll up. However, so long as having enough space, other every users may preserve the file of most 500 MB in this roll.

The quota of magnetic disc is basic with the right had by file , and does not get the restriction of the file location of user file in roll. It does not change that for instance, if user moves file from a file to the other files on identical roll, rolling up space use. But if user duplicates file , in the different file on identical roll, rolling up space use , will be double. Or, if another user has founded the file of 200 KB, you have gotten this file all right, so, the magnetic disc of this user uses , will reduce 200KB, and it will increase 200KB if your magnetic disc uses.

2. Quota

The quota of magnetic disc application roll, and do not get the influence of the file structure rolled up and the layout on physical magnetic disc. Have many files if rolling up , distribute the quota given this roll will entire application have file. For instance, ifProduction \ QAAndProduction \ PublicIs F roll goes up share file, user stocks the file

If single physical magnetic disc contains many rolls, go to quota application every roll, every roll quota is suitable for specific roll only. For instance, if you share two different rolls, difference is F roll and G roll, even if this two rolls on identical physical magnetic disc, also trail respectively for the quota of this two rolls.

Stride across many physical magnetic discs if one rolls up , entire transregional rolls up to use the same quota of this roll. For instance, if the quota restriction of F roll is 500MB, no matter F roll is to stride across 3 magnetic discs still on physical magnetic disc, can not preserve the file that exceeds 500 MB F roll. 3. Quota

In NTFS file system, it is safely identifier that rolling up to use message press user( SID) stock , instead of according to user account name stock. When opening the window " quota" for the first time, the quota of magnetic disc must get user account name from network region controller or local user and group , matches these user account names and the SIDs of current roll user , and using user name to fill "name" the project on row. When region controller or local user gets these names in group, name will show in this field. When looking over quota for the first time, this process begins immediately.

After when get name, may go to its preservation user in" application program data" catalog( ApplicationData Microsoft \ WindowsNT \ DiskQuota) store file slowly, so next time when opening the window " quota", may use these names immediately. However, store file because these are slow possibility continued few angels use have not been updated by Windows, so" quota" window after possibility does not reflect check quota item is for the change that region user account list does.

To get newest user name, please press F5. Then, Windows will refresh the user of every user who comes from network region controller or local user and group to name. According to current network speed and the number of roll user, this process may need some minutes. In this process, if want to look over the name of specific user as soon as possible, may select this project move it the top of list.

4. Quota and conversion

The quota handling of magnetic disc runs all NTFS roll on the computers of Windows2000, Windows XP or 2003 clan operating systems of Windows Server. However, it is already from FAT or it will belong to voluntarily in keeper if FAT32 changes the file on the roll of NTFS, therefore, the quota on these files will by Administrator account management. This is nearly not problem, because keeper possesses infinite roll to use limits of authority. This problem applies to conversion is the existent file before NTFS, and the file after conversion will belong to proper user.

Because the quota of magnetic disc is basic with the right had by file, so as rolling up to do any influence , file has the change of right state, including file system to change , may influence the quota of magnetic disc of this roll. Therefore, when existing roll rolls up conversion before another file system from a file system, you should know that this kind of conversion may arouse the change of all right.

5. The local and

You may start using the quota of magnetic disc on the local NTFS roll of computer and long-range computer. May use the quota of magnetic disc to restrict the quantity of roll space of the different user that registers to local computer , and may restrict the use of long-range user for roll.
May use quota

Many users who register identical
One or more users do not
When personal computer share

Will start using the quota on long-range computer roll, must share these rolls from the root catalog of roll, and you must be the members of the Administrators group of long-range computer. Is other, these rolls must format becomes NTFS, and exist on the computer of operation Windows2000, Windows XP or 2003 clan operating systems of Windows Server.

When system roll goes up realization the quota of magnetic disc, should consider Windows file the space of magnetic disc of use. Basis roll goes up may use space, must install to install the user of Windows probably high quota restriction or do not restrict the space of magnetic disc. If Windows is installed by keeper, , need not be this and operating. Because keeper and the member of Administrators group have the quota restriction that does not get restriction.

2 and Windows Server the role

The NTFS file user quota network space of systems support of magnetic disc of magnetic disc of the system of Windows Server 2003 where manages function and may manage user efficiently is used. The quota of magnetic disc of NTFS roll is trailed as well as control the use of the space of magnetic disc. Keeper may be Windows disposition:

When user has exceeded the designated space restriction of magnetic disc( also allow the space quantity of magnetic disc that user uses ), prevents using the space of magnetic disc further and records incident.
When user has exceeded the designated space

When starting using the quota of magnetic disc, may install two values: The quota restriction and magnetic disc of magnetic disc quota warning rank. For instance, it is 500MB to be able to set up the quota restriction of magnetic disc of user, and it is 450MB to set up the quota warning rank of magnetic disc. Under this kind of condition, user may stock on roll, do not exceed the file of 500 MB. If user the file that on roll stock exceeds 450MB, may record the quota systems configuration of magnetic disc system incident. Only the member of Administrators group then can manage the quota on roll.

May designate user to exceed its quota limit. But want to trail the space of magnetic disc of every user if not think of the visit of refusing user for roll use condition, may start using quota and do not restrict the use of the space of magnetic disc. May also designate no matter user exceeds quota warning rank to exceed quota restriction still whether will record incident.

After starting using the quota of magnetic disc of roll, system takes the automatic use of trailing all user for roll from then. So long as with NTFS file system, roll up format, may roll up in here , network roll as well as may move driver go up start using quota. Additionally, network roll must be shared from the root catalog of roll, but move driver also shares. Windows installs the roll that will escalate voluntarily to use the NTFS edition format in Windows NT 4.0.

Since trailing compressed file according to the size when does not reduce , therefore, can not use file to reduce to prevent user exceed its quota restriction. For instance, if the file of 50 MB is 40MB after reducing , Windows will according to the file big and small calculations of initial 50 MB quota restriction.

The user quota management of magnetic disc is a important task in server management, especially when in large scale intranet Luo, the network space of magnetic disc limits to very much , will cause the plenty of wastes of the network space of magnetic disc on the one hand if not managing the user quota of magnetic disc appropriately , may also bring serious not safe factor on the other hand , may still influence overall network performance seriously, user can not register probably.
