Host-Based Licensing/Unlimited Guests
Licensed per physical host, PerfectDisk 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.
Eliminate I/O Bottlenecks
Proven to increase I/O throughput, and decrease I/O request latency by 35% or more.
PerfectDisk 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
optimizes server virtualization performance management by defragging file systems
for increased IOP performance and completely eliminating performance issues relating
to split I/O requests.
Optimize Host & Guest Machines
PerfectDisk’s virtualization solutions optimize 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.
Virtualization Awareness
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.
Real-Time Fragmentation Prevention with OptiWrite™
PerfectDisk’s OptiWrite™ technology prevents most fragmentation on your drive before
it occurs, which stops 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
in energy costs and in the time required to defragment a file system.

Intelligent Disk Optimization
SMARTPlacement™ is the most advanced file system optimization method available today.
Featuring full customization, SMARTPlacement™ works with the file system to prevent
the creation of performance bottlenecks by consolidating free space and reducing
the amount of time and resources required to optimize a volume. Also eliminates
split I/O requests and fragmentation while maximizing access times.
Automate Shrinking of Virtual Disks
PerfectDisk is a thin-provisioning friendly technology. Save time and money by automating
the offline mounting, file system optimization and shrinking of your thin-provisioned
virtual storage. PerfectDisk is
the only solution that allows you to create automated maintenance schedules for
your virtual storage. PerfectDisk utilizes I/O prioritization and virtual infrastructure
awareness technology to eliminate
resource contention between online and offline systems.
Zero-Fill Free Space
Only PerfectDisk offers a 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.
Free Centralized Management Console
The PerfectDisk Enterprise Console provides complete central management of your
physical and virtual environments. The Enterprise Console features Active Directory
integration, OU Linking, deployment,
monitoring, customizable alerts and reports.
VMware Technical Alliance Partner Solution
PerfectDisk is a Native 64-bit application for exceptional performance on 64-bit
guests. PerfectDisk supports virtual machines of all server roles, including Clustered
and non-Clustered SQL Server, Exchange Server and File & Print server roles.
