WHITE PAPER

SUMMARY

Defragmentation is a critical best practice for any disk-based system, be it a desktop machine or a server platform. The use of server and storage virtualization to lower the cost and increase the efficiency of these systems does not do away with the need for defragmentation—in fact, it increases the requirement for it because of the compounding of the problem at both the physical and virtual level. Consequently, maintaining the performance of a virtual platform through defragmentation is essential as a means of maintaining optimum performance and increasing the lifespan of disk hardware.

ABOUT DISKEEPER

Diskeeper Corporation is well known as a leading innovator in performance and reliability technologies. Its flagship product, Diskeeper® performance technology, has sold over 38,000,000 licenses, making it the most widely used fragmentation solution on earth. In the United States alone, Diskeeper Corporation products are relied upon to ensure maximum system speed and reliability by over 90% of the Fortune 500 and thousands of enterprises and government agencies.

Main Products: Diskeeper 2010 is the only fragmentation solution that prevents up to 85% of all fragmentation before it happens with IntelliWrite™ technology and runs invisibly in real-time using InvisiTasking™ technology. This enormously improves system performance and reliability and extends the life of the systems it is installed on— automatically. The famous Diskeeper defrag engines eliminate pre-existing fragmentation and the small amount that is not prevented.

V-locity™ 2 virtual platform disk optimizer is a recent product release for both VMware and Hyper-V. V-locity is the first optimizer that truly eliminates the barriers to full virtual efficiency. V-locity employs IntelliWrite and InvisiTasking technology to both prevent much fragmentation in the first place and to efficiently coordinate VM resources when defrag is running in the background.

Undelete® 2009 Real-Time Protection. Real-Time Recovery™ protects against all accidental and malicious file deletions. The Windows recycle bin and backup systems can miss capturing some files. Undelete protects all deleted data, allowing for instant file recovery with just a few mouse clicks. Undelete also includes SecureDelete® permanent data deletion for confidential files.
