V-locity 3 - Defrag für virtuelle Systeme
The only way to get maximum I/O performance on virtual servers
The intensified demand for IT network efficiency and lower operating costs is driving the phenomenal growth of virtualization. Effectively shared resources are of critical importance in a virtual environment but are severely impacted by three key barriers.
- I/O bandwidth bottlenecks fast due to accelerated fragmentation on virtual platforms.
- Virtual machine competition for shared I/O resources is not effectively prioritized across the platform.
- Virtual disks set to dynamically grow do not resize when data is deleted. Instead free space is wasted.
V-locity 3 optimizes the entire virtual platform with new technology that operates invisibly with zero system resource conflicts.
On Windows platforms, each V-locity component optimizes its respective OS, preventing most fragmentation from occurring. With the little that does occur, it defragments files and consolidates free space almost immediately. This minimizes unnecessary I/Os passed from the OS to the disk subsystem and aligns data on the drives for previously unattainable levels of speed and reliability.
The following four features found only in V-locity 3 virtual platform disk optimizer are all vital to the efficiency and performance of the virtual system.
The only technology that prevents up to 85% of fragmentation before it can happen. In addition to writing larger sequential disk I/Os from Windows VMs (for much better overall performance), it makes less work for copy-on-write technology which copies/tracks every write. Less need for defrag means less writes to track and fewer I/Os used.
|Virtual Disk Intelligence
V-locity automatically detects special virtual disk types such as the VMware Linked Clones and Microsoft’s Differencing Disks and creates as close to a zero fragmentation state as possible to avoid having data movement from defrag recorded to “change disks”. This results in faster performance for users of these special disks.
Applications and services within VMs cannot effectively prioritize I/O because they have limited knowledge of Host hardware resource usage. Without InvisiTasking, a background defrag process will cut across the production needs of other VMs. InvisiTasking guarantees completely invisible optimization of all Windows operating systems on supported virtualization platforms. It also eliminates the need for scheduling or monitoring defrag where it’s needed, even when VMs are dynamically added or removed.
|Virtual Disk Compaction
Over time, Thin/Dynamic disks only ever grow. They never shrink by themselves, even if data is deleted, because they accumulate free space “holes” that will never be reused. These holes take up space on the host file system that could otherwise be allocate for other VMs. Virtual Disk Compaction provides a GUI showing how much space can be saved with compaction and also provides a one-click ability to initiate this compaction.
