O&O Defrag Professional / Workstation / Server Edition 21.2.2011 (x86/x64) | 47 / 41 / 48 MbO&O Defrag Server 21 solves the performance and stability problems of Windows workstations and servers caused by fragmented hard disks.

Fragmented hard disks put the brakes on the servers in a company and as a result have an adverse affect on productivity.

The level of fragmentation proportionally increases the time needed for accessing a hard disk.

This in turn increases the amount of valuable time lost by each and every employee.

The O&O Defrag Server 21 for Windows servers optimizes your hard disk and packs file fragments securely back together again.

Thanks to clearly displayed graphics and statistics, you can monitor the success of regular defragmentation.

After every run you get a graph showing the before-and-after stats.

You can then base your configuration of the program on these statistics to optimize the success yet more.

O&O Defrag Server 21 puts fragmented files together and maximizes your system speed and offers five different defragmentation strategies, as well as OneButtonDefrag technology for automatic adjustment of the settings best fitting for your system.

The program can defragment drives manually, or fully automatic in the background, keeping your system at peak performance by avoiding build-up of file fragmentation.

Defragmentation jobs can also be scheduled, using various criteria.

Additional features include status reports, cluster inspector, command line interface, optional MMC integration, boot time defragmentation, special support for mobile systems and more.

Fragmentation is the main cause of significant losses in performance in Windows.

Due to the fact that the hard disk is the slowest component of a server, its optimization is an especially important issue.

By using O&O Defrag Server 21, files can be read and written much more quickly.

Optimization of disks in virtual machines and SANs (Storage Area Networks)Users of virtual machines know the phenomenon: the amount of data remains the same, but the memory for the virtual container increases and causes the virtual system to slow down.

The new O&O Defrag Server 21 effectively eliminates and prevents this performance problem from occurring.

For the first time, O&O Defrag Server 21 can now optimize the actual memory allocation for virtual machines and SANs.
