What Are The Problems With Vm Ware
With the increasing popularity of Virtual Machines comes an issue that many may not be aware of. This problem is an age-old issue that has affected systems from the very early days of storage. It can cause hard drive failure leading to expensive data loss scenarios necessitating data recovery professionals. This problem is, of course, fragmentation.
If you are fortunate enough to have very deep pockets then you may be using SSD’s or solid state drives. These still remain expensive and are out of the reach of most users who still have to rely (although getting much faster) on the slowest and some would say the most vulnerable technology in your computer- the hard drive. Hard drive fragmentation can cause problems with virtual machines and in some cases even data loss.
Hard disk fragmentation occurs when files are split in to multiple chunks as they are slotted into spare space on the hard drive. If you are running a solitary OS chances are you have already noticed considerable slow down in your system since purchase. Just imagine two or more OS’s running causing the same file fragmentation! Pretty soon your system could come to a grinding halt.
Fragmentation will not only slow down your computer or server but due to the excessive and unwarranted extra movement of the heads, the life of your storage device(s) can be seriously reduced. The problem is not only limited to single drives however, even if you have a very well specked raid set up, fragmentation can get so severe that the only viable option is data recovery or server rebuild.
Each operating system will have it’s own method of dealing with file fragmentation (or not as the case may be). Whilst Mac OS X will automatically defragment a file under the size of 20mb, windows pays scant regard to how badly files are fragmented. Other systems use a variety of different methods to combat the problem.
Utilizing defragmentation tools can help to alleviate the problem but often the use of some of these tools is very invasive and will render your system virtually unusable while they are running so what other options do you have.
Use automated defragmentation routines: Dependent upon your OS you can normally, either directly in the OS itself or via third party software; schedule defrags to run at times convenient to yourself.
Invest in dedicated hardware. Not the cheapest solution but for business and power user home systems probably the most sensible route. Dedicated hardware could be an additional hard drive (internal or external) a dedicated raid array or even an SSD device. The actual solution will depend on how mission critical the application actually is.
Ensuring your systems are working in tip top condition is vital to maintaining a productive IT infrastructure. For more great computing tips visit the IT support Bolton , or click here for hard drive recovery information and raid data recovery advice.
