BP1013 Best Practices for Enhancing Microsoft Exchange Server 2010 Data Protection and Availability 26
verification would bring the CPU utilization of the system very close to the upper recommended
threshold.
The impact of ESEUTIL on the system can artificially be reduced adding a delay of 1 second for
specified numbers of I/O by using the following parameter in the Windows registry (e.g. 1000 identifies
the number of IOs):
[HKEY_LOCAL_MACHINE\SOFTWARE\EqualLogic\ASM\Settings]
"EseutilThrottle"=dword:00001000
Or, we advise and reinforce that, in the case where a time window to run this activity locally on the
Exchange host cannot be identified, the entire sequence of checksum and verification should be
scheduled and off-loaded to a different host connected to the SAN (Global verification). A different set
of local resources will be dedicated to this process, either dedicated or shared with other services
(usually on a dedicated backup server), and, as a consequence, the Exchange host will not be affected
in any way.
