Managing virtual machine storage efficiently is crucial for optimal performance and resource utilization. Over time, virtual disks can become fragmented and consume more storage space than necessary due to operations like file deletion and virtual machine modifications. This fragmentation can lead to reduced performance and increased storage costs. Reclaiming unused space and improving disk performance can be achieved through a process of merging multiple smaller disk files into a single, contiguous file.
This process offers several advantages, including improved virtual machine performance, reduced storage consumption, and simplified storage management. By reducing the number of disk files and eliminating fragmentation, disk I/O operations become more efficient. Historically, storage space was a significant constraint in virtualized environments, making efficient storage management essential. As storage technology has evolved, the focus has shifted towards optimizing performance and reducing management overhead. This practice remains a vital aspect of maintaining a healthy and efficient virtual infrastructure.
