Exchange 2007 Service Pack 1 introduces several changes in the Extensible Storage Engine (ESE). In my first blog article on the subject,
I discussed the removal of page dependencies and the disabling of
partial merges. In this blog, I discuss other changes we made to ESE
which enhance Exchange.
- Passive Node I/O improvements
- Online Defragmentation
- Checksumming databases
- Page Zeroing
