Virtual Infrastructure Awareness Technology
Virtual infrastructure awareness technology monitors resource availability at the physical host level and enables high resource availability and intelligent real time I/O prioritization during file system optimization. This technology allows optimizations to occur dynamically between virtual guests so as to completely eliminate the resource contention caused by simultaneous optimizations. PerfectDisk 12 vSphere also includes full support for vMotion to track resource availability when a virtual guest migrates from host to host.

Eliminate vSphere Guest I/O bottlenecks
PerfectDisk 12 vSphere is a complete solution that optimizes your physical host, guest machines, and your storage solution to eliminate I/O throughput and I/O latency bottlenecks. This includes the optimization of both fat and thin provisioned virtual storage on both local and external RAID / SAN solutions.

Space Management ** NEW in 12.5 **
PerfectDisk's new Space Management recovers disk space by detecting and removing duplicate files such as text documents, pictures, music, and videos. Recycler purges the Recycle bin and removes temporary files so that your drive remains clutter free. With Space Reports you can view a graphical and statistical report of file usage and allocation.

P2P Remote Capability ** NEW in 12.5 **
Take control of any client running on a remote computer with the power to access features normally only accessible via a local client. Make on the fly changes to client configurations and behaviors without the need to use Remote Desktop. PerfectDisk also supports direct connections to remote clients via the Enterprise Console.

Automatic background optimization
PerfectDisk's new OptiWrite™ technology prevents most fragmentation on 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 occurring. 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 in energy costs and in the time required to defragment a file system.
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.

Dramatically Improve vSphere Performance
Proven to increase I/O throughput, and decrease I/O request latency by 35% or more. PerfectDisk 12 vSphere enables the best possible performance for your virtual machines and maximizes the performance of your storage solution. Using I/O prioritization for zero resource contention overhead, PerfectDisk 12 vSphere optimizes server virtualization performance management by defragging file systems for increased

IOP performance and completely eliminating performance issues relating to split I/O requests.
Testing performed on identical disks using VMware’s vscsiStats show that defragmentation of Windows guest VM’s delivers significant performance and throughput improvements. The PerfectDisk defragmented disk produced the following:

Using actual vscsiStats disk latency data we see the PerfectDisk defragmented disk (VM2) practically eliminated the total number of disk IO taking 50000µs (50ms) or longer. The mean latency for the two disks was 58ms for VM1 and 35ms for the PerfectDisk disk.

VMware Technical Alliance Partner Solution
PerfectDisk 12 vSphere is a Native 64-bit application providing exceptional performance on 64-bit vSphere guests. PerfectDisk 12 vSphere supports virtual machines of all server roles, including Clustered and non-Clustered SQL Server, Exchange Server and File & Print server roles.

Host based licensing – Unlimited Guests
Licensed per physical host, PerfectDisk 12 vSphere is a cost effective solution with exceptional ROI. Each licensed host supports unlimited guest licenses for easy license management and superior value. No additional costs per CPU or CPU core. Volume pricing is available.
