PageFile -2008 R2 64Bit

So..My Hard Drive is in dyer need of space, it only has 121mb left. The page File is 9gb and system managed. My server has 6Gb of Memory.

Virtual Memory Settings
I have alot of Data on the E:\ Drive. Whats the best way to change c:\ page file so that it resides on E:\? Does this erase or effect my data on E:\? Do i automatically reclaim the space on the c:\ after this is done? I was thinking of making the c:\ drive set statically at 2048MB and E:\ 9GB static? Thoughts & Solutions please.

Thanks in Advance?

You CAN lower the size of the page file, but if the system recommends 9GB I would leave it at that size.  You CAN change the page file to be on the E: drive, it will just take up 9GB more space on the E: Drive.  It will not affect any of the data you have there now.  

I would go ahead and move the page file to the E: Drive.  You will need to reboot for it to take effect.  It will free up the space on C: if moved.

Are these seperate PHYSICAL drives?  Try getting rid of temp files and trash and such first.  The, look at programs that can be removed and re-installed on E:.  Windows LOVES the C:\ for the page file, don't know why, I think it is a throwback to the days of Win 95.

Well I would keep the pagefile that size. You can move the pagefile to another partition which might be a good idea.

You can download this product to help you determine what is taking the space up as well. http://windirstat.info/ From here you can determine if you can move this data to another partition as well

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Same physical disk, does this matter.

In case memory usage of server less than 6GB.

you can simply disable paging file.

Remove the click from "Automatically manage paging  file for all drives"

Now select "No paging file"

This require reboot and paging file will remove automatically.

Yes.  Same disk means there is no real savings in performance.  You can still do it, but the performance gains will not be there.

Gajendra_Rathod...What are the repercussions from not having a pageFile?

 airborne1128....Not really looking at performance gains, just need more space on C:\ drive.

So if i resize the c:\pagefile to static 2500mb and e:\ to 9000mb, this doesnt do anything to the data that is residing on E:\drive does it? Do i get my reclaimed space back on c:\Drive?

Darius GhassemCommented:
You can see a performance hit without a page file

Glen KrinskySystems AdministratorCommented:
@earlyriser99...that is correct.  However, windows would prefer to have the pagefile on c:\.  It may take some work and monitoring, but I would re-install applications from c:\ to the E:\ and leave the page file.  However, splitting it possible as well...just not preferred.

You HAVE to have a pagefile.  Without it your machine will not run properly if at all.

By splitting it up....Will i reclaim some of my C:\ HD space?
0
Darius GhassemCommented:
Yes if you limit the size on C then the system will only use 2GB for example
0
Glen KrinskySystems AdministratorCommented:
Yes.  In fact, you only NEED 250MB on C:\.  That is for the dumpfile.

Gajendra RathodSr. System AdministratorCommented:
Paging file is use to increase RAM capacity.

In case you disable it , there will no issue until server utilization exceed 90% to 100%.


In case RAM utilization is more that 6GB then you should not change this setting.

Thanks  everyone for you input....Im super paranoid so sorry for all the silly questions, one more and i will award point. When i put the 9gb on the E: drive, it should do anything to my data that resides on the E:\drive right?
0
Glen KrinskySystems AdministratorCommented:
Correct.  Your data will be fine.  All the system will do is allocate 9GB for the page file.  I recommend defraging the drive FIRST.

it won't alter your existing data, it will just use up however much space you designate for that page file.. basically it just adds another file to the E:\ Drive.

confirming some posts, debunking others, and providing some missing details (or so I hope):

1.  The only reason to have a pagefile on C: is for memory dumps in the event of a STOP error.  While it's always POSSIBLE you'd need a full memory dump, I cannot recall one single instance in 17 years as an IT Pro that I've needed a full memory dump (in order to have a full memory dump, the Pagefile must be on C: and equal to RAM + 2 MB (I think, if memory serves).  So odds are VERY, VERY good that removing the pagefile from C: will not have an adverse effect, all other things being equal.  (I do leave a small 250-500 MB Pagefile for minidumps, but that's it and frankly, I'm not sure that's even necessary for minidumps.

2. Completely agree - DEFRAG the E: drive before putting a pagefile there.  Better still, consider adding a hard drive you can dedicate to non-critical things like the pagefile, shadow copies, and other data.  This disk need not be RAIDed but likely will need to be the same interface type - SAS if the server uses SAS, SATA if the server uses SATA.  At least if it's on the same controller.

3. You CAN have a system without a pagefile... BUT it's generally not recommended.

How to determine the appropriate page file size for 64-bit versions of Windows Server 2008 and or Windows 2008 R2
http://support.microsoft.com/kb/2021748
(Note: in this article, Microsoft states:
The 64-bit versions of Microsoft Windows Server 2008 and Microsoft Windows Server 2008 R2 can support more RAM than the 32-bit versions of Windows Server. When lots of memory is added to a computer, a paging file may not be required. When you use the Memory-Pages/sec counter to measure paging file use, the value that is returned may not be accurate. To obtain an accurate measurement of paging file use, you must also use other performance counters. You can use System Monitor measurements to calculate the size of the paging file that your computer requires.

Windows Server 2008 and Windows Server 2008 R2 Domain Controllers are not supported without a configured pagefile. Because the algorithm the LSASS database cache depends on the "transition pages repurposed/second" perfmon counter, a pagefile is required to make sure that the database cache is capable to release memory if memory is requested by other services or applications.
