subject: Complete Assistance For Recovering Data From All Major Raid [print this page] Business units are using technology to manage unable data that store their valuation powerful servers. The technology used for storing data is known as RAID (Redundant Array of Independent Disks). Here, multiple Hard disks are arrayed to form a single storage system and the data is distributed among these disks. Although, servers are designed to be sturdy and reliable yet they might also crash due to several reasons. Servers crash is the worst situation that a company may face. In such a situation, the data become inaccessible and, as a result, the day-to-day business activities get disturbed. The need of hiring a RAID data recovery ( Recupero Dati Raid ) service arises here.
The re-storage depend upon the level of RAID that you have used for storing data. The complexities and tools differ according to the configuration of storage system. To make you better understand the levels and complexities involved, here are some of the major levels of RAID, with measures to be taken when they crash:
RAID 0
It is also known as stripe set or stripe array, where data is located in stripes between two or more drives. Each disk add storage space to the array, which is limited to the volume of the smallest disk. It is the fastest and most efficient configuration, but is not fault-tolerant. As there is no parity, it is the most popular level among performance seekers.
When one of the drives fails, you may face problems with RAID 0. Please shut down the server and get a professional RAID recovery ( Ripristino Raid ) service.
RAID 1
Mirroring is the technique used in this level, wherein data on the two disks is identical, providing complete duplication. It provides least storage efficiency, because it is a two-drive array. However, it is the fastest system with fault-tolerance. If a drive fails, the data is available on other one; but, if both the mirrored arrays become inaccessible, then you must seek a RAID recovery ( Ripristino Raid ) assistance.
RAID 5
It is a striped volume with fault-tolerance and parity control. Data is stored across three or more physical disks. With the increased number of disks, the storage efficiency goes up. RAID data recovery ( Recupero Dati Raid ) solutions from a reputed company are advised in case you are facing any problem with this level of RAID. An access to the data is possible if only one drive fails, on a degraded level with no fault tolerance. The faulty drive must be replaced at the earliest in order to minimize the chances of data loss. Please do not rebuild the RAID in case two or more drives fail as it may lead to complete data loss.
