With massive electronic data growth occurring today, there is now a much greater need for storage. SAN is at the forefront for most storage solutions and providers such as HP, IBM and NetApp, to name a few, are providing the necessary platforms to cater to this. Virtualisation and cloud solutions are promising less hardware in this respect, but data storage if held locally, will inevitably mean acquiring more hardware. This additional hardware is where the problem will lie in terms of cost for many companies today. Diagram of Disk I/O as it travels from Operating System to SAN LUN It stands to reason then that making full use of your SAN potential is vital. A common misconception related to SAN storage environments is that they don’t suffer from fragmentation related issues. This is the “party line” being handed out by many of the storage providers. There are plausibly a couple of reasons for this. Firstly, that each SAN provider will have their own propriety logic when it comes to ar...

HyperFast SSD Optimizer Why your Solid State Drive is not as fast as it used to be By: Mandeep Birdi, Technical Consultant Diskeeper Corporation Europe SSD hard drives are becoming increasingly more popular. Many portable devices such as laptops, PDA's, Tablet PC's and Netbooks are being used with SSDs. Although prices are still astronomically high - a 1TB SSD setting you back a mere £3000 - sooner or later the prices will fall into a more accessible range and they will become far more widely used. Of course solid state drives have several distinctive advantages. Faster access times, lower power usage and rather pleasingly, run completely silent. The main disadvantage, although possibly undetectable at first, is over time you'll probably start to notice the write speed slowing down - even slower than those of conventional hard drives. Solid state drives can access any location on the drive in the same amount of time. This is one of the key features over hard drives. So ther...
