 PerfectDisk 11 vSphere is the only disk optimization/defrag solution for VMware vSphere that optimizes Windows® guests and monitors resources at the host and guest levels.
● Price per host – No cost for guests
● Maximize Virtual Machine performance
● Integrated support for vSphere, vMotion, vCenter, ESX and ESXi
● The only solution that intelligently avoids I/O resource contention
● Full Central Management solution - Integrates with vSphere Client
Virtual Performance Issues
Virtualization has the potential to reduce costs by saving money on physical footprint, power, hardware costs, and support personnel. But the savings can only be realized if the virtual guests are properly maintained. File and free space fragmentation are known performance killers on virtualized Windows guests because they cause slower disk reads and disk writes.
Excess I/O activity, caused by fragmentation, creates resource contention between virtual guests and elevates resource usage on the vSphere host which in turn creates resource bottlenecks and slows system performance. File system fragmentation can only be addressed by logically defragmenting the files. SAN and/or RAID disk storage do not alleviate these problems. However, the PerfectDisk 11 vSphere Bundle does improve SAN/RAID performance.
Disk Optimization with Virtual Awareness
The PerfectDisk 11 vSphere Bundle is the only disk optimization/defrag solution that looks at resource usage at the host and guest levels. It also includes a plug-in for enterprise management using vSphere and supports central management with vCenter and live migration with vMotion.
The PerfectDisk 11 vSphere Bundle uses its patent-pending Virtualization Awareness technology to transparently defrag files and consolidate free space into the largest possible contiguous piece for optimal read/write performance. Unlike other virtual defrag solutions, virtual guest operating systems running PerfectDisk 11 vSphere will not compete with each other for system resources and they will reduce the total resource consumption on the vSphere host. |
