VMware Workstation Defrag
Optimize your VMware environment. PerfectDisk 12 VMware Workstation has been enhanced with new features to improve performance and speed of your host and virtual drives.
Fragmentation Prevention with OptiWrite™
PerfectDisk's new OptiWrite™ technology prevents most fragmentation in your drive before it occurs, which prevents your system from slowing down. OptiWrite™ detects when Windows is going to fragment files and intelligently redirects I/O to stop the fragmentation from occuring. System performance is maintained and the need to utilize CPU and Disk I/O resources to defragment files is greatly reduced. Because less defragmentation is needed, there is a direct benefit in the form of energy saved in both CPU usage and in the reading and writing to a disk. It saves users both in energy costs and in the time required to defragment a file system.
Enhanced Capabilities for Virtualized Environments
Auto detects and configures PerfectDisk based on virtual hard drive type including Thin-provisioned drives, linked clones and non-persistent drives. Snapshots and linked clones are set to a no-defrag status.
Short Stroke Method for Thin-Provisioned Environments
New Short Stroke method improves optimization speed and improves support for Thin Provisioned drives:
- Allows for optimization of thin provisioned disks without introducing excessive growth.
- Works with the new Zero Fill pass in conjunction with thin persistent storage systems to reclaim up to 30% more storage.
- Accelerate the optimization of large disk array by drastically shortening seek times for all electromechanical drive types and arrays.
Zero-Fill Free Space Saves Storage Space
Only PerfectDisk offers Zero-Fill free space capability that consolidates free space then zero-fills that space. When moving from a physical to virtual environment, zero-filling the free space after optimization of the physical system saves storage space on the virtualized system. In a thinly-provisioned environment zero-filling a virtual machine after optimization and then compacting it gives you a smaller machine that uses less storage. This also allows for recovering of zero-filled free space when using one of the growing number of zero-detect SANs from HP/3PAR or HDS.
StealthPatrol™ Automatic Defragmentation
PerfectDisk’s exclusive StealthPatrol™ technology is used to automatically prevent fragmentation and optimize your drive only when your computer is idle. Automatic defragmentation affords you the flexibility to invoke a defragmentation pass when Windows is idle and runs in the background. StealthPatrol checks CPU and Disk I/O thresholds to determine if the machine is busy or not and the amount of time since the last defrag pass before it starts the automatic defragmentation in the background. It also gives an option to set PerfectDisk behavior when a user-defined list of Windows applications are running and the automatic defragmentation schedule is about to start.
Advanced Boot Time Defrag
PerfectDisk's advanced boot time defrag capability is able to defragment files that otherwise would remain fragmented such as the Windows pagefile.sys or the file system's MFT (Master File Table). PerfectDisk employs a sophisticated locking mechanism to ensure the defrag is done safely. PerfectDisk 12 includes significant enhancements to the boot time defrag locking mechanism which greatly improves driver compatibility when locking drives, and leads to a much smoother boot time defrag operation. Internal and external testing has verified that these conflicts have been virtually eliminated.
New Dynamic Zone Engine
PerfectDisk 12 improves its operations for faster and more efficient defragmentation and optimization. During processing, PerfectDisk deals with parts of a drive at once - a zone. PerfectDisk 12's new dynamic zone engine significantly reduces the overhead of moving zones in and out of memory, drastically improves RAM utilization and enhances engine speed on both small and large drives, but particularly on large drives.
