Raxco PerfectDisk 11.0 Exchange, 1u PDEX1 Merkblatt

The normal daily database maintenance performed with Exchange does not address the internal free space created
when records are deleted. This free space remains the “property” of Exchange until an offline defragmentation can be
performed and returns the free disk space to the operating system. It is not uncommon to recover 10 - 20% of the total
Exchange database size with this defragmentation. PerfectDisk 11 Exchange can help check unnecessary Exchange
growth and manage storage costs.

Data store defragmentation and re-indexing reduce I/O and CPU resource consumption and deliver better Exchange
performance. Unused disk space is recovered and returned to the operating system where it can be made available to
end-users.

Exchange consists of a complex directory structure containing several data stores that are constantly growing.
E-mail and other Exchange items are being added, changed and deleted on a continuous basis. The result is an
Exchange Server with highly fragmented internal data structures and increasingly inefficient index pointers. Over time,
Microsoft Exchange performance suffers and the growing data stores consume disk space well in excess of the actual
data they store.

PerfectDisk 11 is a fully-enabled Windows 2008 R2 and Windows 7 certified application that defragments disks and
consolidates free space in a single pass. Its patented optimization algorithm eliminates most fragmentation before it
occurs, shortens defragmentation run times and utilizes fewer resources than typical defragmenters. PerfectDisk and
PerfectDisk Exchange are the combination of speed, completeness and intelligence you require as part of your storage
management strategy.

PerfectDisk empowers system managers, small business and  home users by delivering flexibility, automation, and
high-performance to help you thrive in constantly changing system network and home environments.  PerfectDisk
