Dynamic HDD and pagefile.sys Questions...

We have a client machine on the network running Windows
2000 Server but not as domain controller. The network is
a SBS2000 one.

The client is a Dell PowerEdge 2400 (Dual-PIII with 1536MB
RAM) with a RAID-5 disk array consisting of x5 36GB SCSI
in RAID-5 with a HotSpare in bay 6. The RAID-5 array is
Dynamic through Disk Manager (we use Dell OpenManage Array
Manager) with a C Drive partition of 8GB and data
drives/volumes called N,P,Q,T each dynamic with
unallocated space we can assign to N,P,Q and T - should we
need to increase the partition sizes.

The questions are as follows:

1. The user recently had his C Drive Free space reduced to
just a few MB. So he moved his pagefile.sys from C Drive
to Q Drive. This released around 2GB of space from C
Drive. What risk is there of moving pagefile.sys from C
Drive to a data drive called Q? Q now has in the root
pagefile.sys of 2.5GB.

2. When the swap file was moved, this was set using an
initial size of 2500MB and a maximum size of 4095MB. We
tried entering 4096MB as the max size, but a pop-up
dialogue box requested us to set this to 4095 - which
seems quite a strange number. Why is this?

3. The user wants to increase his C Drive partition by
assigning some Unallocated space to C. Is this a good
thing to do? Please can someone tell me whether this is
OK - as the user wants a lot more free space in C - the
only way possible is to assign more to C. In actual fact,
I seem to recall the user trying to assign more MB to C
Drive - but could not - is this true? In which case, how
can we allocate more space to C by making use of the
Unallocated space?

If someone could kindly answer the questions above this
would be most appreciated.

1. In order to create a full memory dump, a page file on the boot partition
is needed. If you really need a dump, it is possible to use the MAXMEM
switch in boot.ini to use less RAM, and thus a smaller page file, just to
get the dump.

2. 4095 is less than 4GB, even with only a MB, but 4GB is too much. You can
circumvent the limit, this MS Knowledge Base tells you how:

3. There is currently no supported way of increasing the size of the boot
or system volume on a dynamic disk without a backup and restore.
