What's new in PerfectDisk^® 14?

PerfectDisk 14 adds Windows event log integration, thin-provisioned drive auto-detection, automated reporting from PerfectDisk clients to their managing PerfectDisk Enterprise Console and enhanced integration with Citrix Servers.

NEW! Windows Event Log Integration

PerfectDisk-identified fragmentation-related issues are now logged to the Windows Application Event log. These alerts can then be detected by 3rd-party monitoring programs such as Microsoft System Center and HP Operations Manager. This integration allows customers to use their existing monitoring/management tools to monitor for performance degradation caused by file and free space fragmentation.

NEW! Thin Provisioned Drive Auto-Detection

PerfectDisk now automatically detects thin-provisioned drives in both physical and virtual environments. For drives that are auto-detected as thin-provisioned, PerfectDisk automatically will configure itself so that defrag operations performed on the drive are less likely to fully provision the drive. 

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 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 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

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

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.
• Accelerate the optimization of large disk array by drastically shortening seek times for all electromechanical drive types and arrays.

Dramatically Improve vSphere Performance

Proven to increase I/O throughput, and decrease I/O request latency by 35% or more. PerfectDisk 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 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:

• 28% reduction in total IO
• 1,200% improvement in large I/O (>524K)
• 49% reduction in I/O taking longer than 15ms
• 28% improvement in throughput

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