How to extend RAID 5 partition in Windows Server 2003/2008/2000?

Do you encounter the problem that system C: drive running out of space on your RAID 5 array? Do you want to extend RAID 5 partition to solve this low disk space problem without deleting, formatting partition or rebuilding the Server? Do you know the reliable way to extend RAID 5 partition without destroying any data? Don’t worry, in this article I’ll tell you how to extend RAID 5 partition in Windows 2008/2003/2000 Server within minutes and no data loss. Brief Introduction of RAID 5 As one of the most popular RAID levels, RAID 5 stripes both data and parity information across three or more drives. It is similar to RAID 4 except that it exchanges the dedicated parity drive for a distributed parity algorithm, writing data and parity blocks across all the drives in the array. This removes the “bottleneck” that the dedicated parity drive represents, improving writing performance … Continue reading

What is RAID 5 and its features, advantage and disadvantage?

RAID Level 5: Some commonly used RAID Level 5 is a cluster-level implementation of data striping with DISTRIBUTED parity for enhanced performance. Clusters can vary in size and are user-definable but they are typically blocks of 64 thousand bytes. The clusters and parity are evenly distributed across multiple hard drives and this provides better performance than using a single drive for parity. Out of an array with “N” number of drives, the total capacity is equal to the sum of “N-1? hard drives. For example, an array with 4 equal sized hard drives will have the combined capacity of 3 hard drives. This is the most common implementation of data striping with parity. In this example 25% of the storage purchased is used for duplication. Controller Requirements: Requires a moderately high-end card for hardware RAID, supported by some operating systems for software RAID, but at a substantial performance penalty. Hard … Continue reading
