RAID, especially RAID 5, is a technology preferred by Windows Server users due to its great level of data reliability and input/output performance. Thus, to optimize the usage of Windows Server, IT administrators need to repartition RAID (RAID 5) regularly. This article will help you gain better understanding of RAID, mainly RAID 5, and provide the safest solution to repartition RAID (RAID 5) on Windows Server.
What Is RAID?
RAID (Redundant Array of
Independent Disks) is a technology that allows computer users to achieve high
levels of storage reliability from low-cost and less reliable PC-class
disk-drive components, via the technique of arranging the devices into arrays
"RAID" is now used as an umbrella term for computer data
storage schemes that can divide and replicate data among multiple hard disk
drives. When multiple physical disks are set up to use RAID technology, they are
said to be in a RAID array. This array distributes data across multiple disks,
but the array is recognized by the computer user and operating system as one
RAID is used either to improve reliability and availability
of data, ensuring that important data is available more often than not, or
merely to improve the access speed to files. There're several levels of RAID
according to various combinations of approaches giving different trade-offs of
protection against data loss, capacity, and speed, including RAID 0, RAID 1,
RAID 2, RAID 3, RAID 4, RAID5 and RAID 10 (1+0), etc. Among them, RAID 0, RAID
1, and RAID 5 are the most commonly found, and cover most
What Is RAID 5?
A RAID 5 uses block-level
striping with parity data distributed across all member disks. RAID 5 has
achieved popularity due to its low cost of redundancy. This can be seen by
comparing the number of drives needed to achieve a given capacity. RAID 1 or
RAID 10, which yields redundancy, gives only S / 2 storage capacities, where S
is the sum of the capacities of N drives used. In RAID 5, the yield is S x (N-1)
As an example, four 1TB drives can be made into a 2 TB redundant
array under RAID 1 or RAID 10, but the same four drives can be used to build a 3
TB array under RAID 5. Although RAID 5 is commonly implemented in a disk
controller, some with hardware support for parity calculations (hardware RAID
cards) and some using the main system processor (motherboard based RAID
controllers), it can also be done at the Operating System level. A minimum of
three disks is required for a complete RAID 5 configuration. In some
implementations a degraded RAID 5 disk set can be made (three disk set of which
only two are online), while supports a fully-functional (non-degraded) RAID 5
setup with two disks - which function as a slow RAID1, but can be expanded with
What is the easiest and safest solution to
repartition RAID 5?
As mentioned above, due to its low cost of
redundancy, RAID 5 is popular among Windows Server users. And repartitioning
RAID 5 is a regular task for IT administrators to maximize the performance of
their Windows Server computers. Since Windows Servers usually store the most
important data of a company, IT administrators should be extremely careful when
choosing software to work on their server computer, including partition software
to repartition their RAID 5.
Partition Wizard Server Edition is a
professional partition manager that
can work perfectly well with hardware RAID, especially for RAID5.
to repartition RAID 5 without data Loss with this partition
Partition Wizard Server Edition is Compatible with all types of
hardware RAID (e.g. RAID 0, RAID 1, and RAID 5) on both Windows Server
2000/2003/2008 and desktop 2000/XP/Vista 32 and 64 bit systems. It also provide
a range of powerful functions to repartition RAID, especially RAID 5, including:
Resize and Move partitions, Copy partition, Copy disk, Create and Delete
partitions, Format partitions, Convert partitions, Explore partitions, set
active partition, etc.
Among these functions, Partition Copy Wizard and
Disk Copy Wizard offer you an easy way to back up your valuable data before any
operations on your RAID 5 partition. Resize utility allows you to resize your
RAID 5 without any data loss.
