在32 bit作業系統中non-paged pool最大是256MB
There is a limitation with the 32 bit windows Server 2003 with volumes greater than 5 TB on which shadow copy is enabled (i.e on a single volume), a very basic chart is 1 TB of drive uses ~ 24MB of non-paged pool; so a 10tb drive would need 240mb
With 64-bits this isn’t an issue as the paged pool and non paged pool memory can grow to a maximum of 128GB
