What is the best solution to expand RAID 5 partition on Windows Server without data loss? Well, you might never think about expanding your RAID 5 partition, not to mention the solution to expand RAID 5 partition. For example, your system partition on RAID 5 is running out of space, what will you do? Recreate another RAID 5? This solution can do the trick, but the best solution, upon comparison, is to expand this RAID 5 partition without data loss.
RAID (Redundant Array of Independent Disks) technology has been proved as the best technology to protect large-volume data while providing excellent performance. There have been a variety of implementations of RAID, and various products have been delivered to the market. Among them, the most widely adopted RAID technology is hardware RAID 5, which offers the good performance with superior reliability.
Generally speaking, RAID 5 uses a form of strip with parity to maintain data redundancy. A minimum of three drives is required to build a RAID 5 array and they should be identical drives for the best performance.
With that information in mind, here is an example of how a RAID 5 array would work. Each row in the chart represents a physical block on the drive and each column is the individual drive. The numbers in the table represent the data blocks. Duplicate numbers indicate a duplicate data block. A "P" indicates a parity bit for two blocks of data.
The parity bit shifts between the drives to increase the performance and reliability of the data. The drive array will still have better performance over a single drive because the multiple drives can write the data faster than a single drive. The data is also fully redundant because of the parity bits. In the case of drive 2 failing, the data can be rebuilt on the basis of the data and parity bits on the two remaining drives. Data capacity is reduced due to the parity data blocks. In practice the capacity of the array is based on the following equation where "n" is the number of drives and "z" is the capacity:
(n-1) z = Array Capacity
In the case of three 500 gigabyte hard drives, the total capacity would be (3-1) x 500GB or 1000 gigabytes.
Hardware RAID 5 implementations can also have a function called hot swap. This allows for drives to be replaced while the array is still functioning to either increase the drives capacity or to replace a damaged drive. The drive controller then takes time while the array is running to rebuild the data array across the drives. This is a valuable feature for systems that require 24x7 operations.
Below is the screen shot of RAID 5 helping you get better understanding of RAID 5 visually before you expand your RAID 5 partition.
There're several shining points of RAID 5. The typical advantages are:
Increase of storage array performance
Full data redundancy
Ability to run 24x7 with hot swap
Due to its excellent reliability and performance, RAID 5 is preferred by high-end Windows Servers users, especially Window Server 2003 users.
Generally, the purpose of expanding RAID 5 partition is to maximize the performance of server computers by having more disk space on RAID 5.
Here're two cases regarding computer users' demand to expand RAID 5 partition:
1. I have just added a new drive to my existing RAID 5 and then the RAID 5 seems to be out of place. It's obvious that I need to expand my RAID 5 partition for further usage. Well, easy operation is appreciated.
2. I would like to create new drives to my current RAID 5 array which is, however, too full to hold more disks. I know I need to expand my RAID 5 partition. But I still dare not to operate it for fear that I might destroy the valued data on the server.
You may have come across such situations and have the same concerns.
