I think you may be on to something.. I thought it was on auto.. but apparently it had a set size.. I switched it to auto for all drives.  Do you thing vmserver gave it a set size?

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

>I switched it to auto for all drives.
that is actually a bad idea.
the swap file should be on 1 single partition and have indeed a fixes size.
As you doubled the RAM, you should double the size of the page file also (and keep it on a single disk)

Edit the BOOT.INI file and add a switch to the end of the line that loads the OS.

/PAE

Reboot.

Let us know.

I have to let you guys know tommorow.  I went home before I got your answers.  Does it matter which drive I have the paging on for?  What size should I set for 8 gig?
0
 
Netman66Commented:
Minimum - 8GB
Maximum - 12GB

Make sure you have that space available and you never run short.

What does /PAE do?
0
 
Netman66Commented:
It tells the Kernel to use Physical Address Extensions.  This will let Windows see all the RAM.

Have a read if you're interested:

Thanks :-) I just googled PAE and thats exactly what I was reading.. Learning some good stuff from you guys.  I always thought it was best to just let windows manage the page file.  This is the first machine I've had over 4 gig.  Do you think it will run http://www.vmware.com/products/server/ ok?

Netman66Commented:
It should do just fine.

You cannot set a page file over 4095MB.  You cannot have more than one page file on a partition without registry hacking.

Does it make sense to hack the reg for a larger swap file?  If so, how is it done?
0
 
Netman66Commented:
No it doesn't.

Place the pagefile on two drives if you need that much.

OK.. the other thing is I can't seem to find a boot.ini file... if I create a new one do I have to have anything in it other than /PAE
I forgot if anything else had to go there.

Netman66Commented:
Boot.ini is a hidden file on the root of the C: drive - it's there.

BLipmanCommented:
It is a "Protected Operating System File" and thus, to see it, you will need to enable "Show Hidden Files" AND disable "Hide Protected Operating System Files" from Windows Explorer -> Tools -> View.

OK guys.. your suggestions worked.  It now recognizes the 8 gig, but as soon as I put the 4 2 gig chips in the system seems to drag even though it sees everything.  With the 2 2 gig chips it seems "snappy"  Any ideas why?

It seems ok now.
