NTFS Destructive in virtual environments? Back in the earlier days when the new filing system came in, users soon became aware of the detrimental effects of fragmentation, and although a deliberate mechanical design for hard disk storage, it became no less a costly burden to system users due to the degradation and loss of computer performance. However, it what soon understood that defragmenting computer gave back the lost performance, increased system reliability, well as as increased hardware life and many companies thereon had procedures in place or took action to handle fragmentation. Today, as companies start migrating across to virtual networks, they will find themselves in a similar situation as those early days in terms of discovering the problem caused by fragmentation except now we see this issue in a virtual environment, and this time it is thrice as bad leading to dramatic increase in IOPs. Fragmentation on virtual systems just as machines, so it does fragmentation has a detrimental effect in physical windows in a virtual environment in fact, up to 3 times worse! Server virtualization allows multiple operating systems to run simultaneously on a physical server as virtual machines (VMs). Like non-virtualized system performance on virtual systems is degraded by disk fragmentation. The performance degradation is several times worse on virtual systems than on physical systems because fragmentation happens at different levels. To handle all the different levels have...
