SAN storage and NTFS now has become the use of storage area networks (SANs) to meet the storage needs. SANs typically used a clustered/SAN file system to match disk array as a virtual memory space. This is done not NTFS, but proprietary software from a SAN hardware or a ‘ software provider is supplied. This file system runs generally parallel to NTFS, instead of replacing the latter. Each file system acts almost like a « virtual hard disk ». A virtual component over another stored to use (i.e. a file system in addition to another) is quite practical and increasingly widespread.
What does the provider a SAN file system with this has no influence on NTFS. Statements such as « Defragmentation is unnecessary » could possibly distributed. Provider of SAN file systems can possibly offer optimization strategies. In this case, data on hard drives across distributed, while the system time are typically « learns » – data requests not balanced via SAN spindles distributed. In general this applies also to the disk striping (RAID). SAN designers and developers agree that NTFS defragmentation represents a real problem, and that a more advanced kind of defragmentation is important (« simple » defragmenters can cause problems actually even more serious). File fragmentation also means a considerable physical strain of the hard disk.
To access data in fragmented files, the hard drive head must be moved more and more frequently. The more the hard disk head moves, the smaller will the mean operating time between failures (MTBF), which shortens the life of the hard drive. The previous practice of regular, scheduled defragmentation belongs to the past. For hard disk sizes and storage volume today’s systems these methods are no longer efficient. Use a native defragmentation tools is simply not comprehensive enough to achieve the required effect and to enable that originally provided your system performance. Reliability is required around the clock regardless of applied backup systems and storage technologies (SAN, RAID). Maximum system uptime is essential, and this reliability is essential.
