How to Create Dynamic Disk Volumes?

What is Dynamic Disk? A dynamic disk is a physical disk that provides features that basic disks do not, such as support for volumes spanning multiple disks. Dynamic disk is supported in Windows XP Professional/Vista/Windows 7 and Windows Servers 2000/2003/2008. A disk initialized for dynamic storage is called a dynamic disk. A dynamic disk contains dynamic volumes, such as Simple Volume, Spanned Volume, Stripped Volume, Mirrored Volume and RAID-5 Volume. With dynamic disk, you can perform disk and volume management without the need to restart Windows. Note: 1. Dynamic disks are not supported on portable computers or on Windows XP Home Edition-based computers. 2. You cannot create mirrored volumes or RAID-5 volumes on Windows XP and Windows Vista, Windows 7 add the feature to support Creating Mirror Volume. However, you can create all dynamic volumes in Windows Server editions, including Windows Server 2000/2003 and Server 2008. 3. All volumes on … Continue reading






Is RAID 10 the same as RAID 01?

RAID Levels 0 1 (01) and 1 0 (10) Common Name(s): RAID 0 1, 01, 0/1, “mirrored stripes”, “mirror of stripes”; RAID 1 0, 10, 1/0, “striped mirrors”, “stripe of mirrors”. Labels are often used incorrectly; verify the details of the implementation if the distinction between 0 1 and 1 0 is important to you. Technique(s) Used: Mirroring and striping without parity. Description: The most popular of the multiple RAID levels, RAID 01 and 10 combine the best features of striping and mirroring to yield large arrays with high performance in most uses and superior fault tolerance. RAID 01 is a mirrored configuration of two striped sets; RAID 10 is a stripe across a number of mirrored sets. RAID 10 and 01 have been increasing dramatically in popularity as hard disks become cheaper and the four drive minimum is legitimately seen as much less of an obstacle. RAID 10 provides … 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






What is RAID 1 and its features, advantage and disadvantage?

RAID Level 1: Commonly called Mirroring RAID Level 1 is the pure implementation of data mirroring. In a nutshell RAID Level 1 gives you fault tolerance but it cuts your usable capacity in half and it offers excellent throughput and I/O performance. This RAID level is often used in servers for the system partition for enhanced reliability but PC enthusiasts can also get a nice performance boost from RAID Level 1. 50% of your purchased space will be used for duplication. Description: RAID 1 is usually implemented as mirroring; a drive has its data duplicated on two different drives using either a hardware RAID controller or software (generally via the operating system). If either drive fails, the other continues to function as a single drive until the failed drive is replaced. Conceptually simple, RAID 1 is popular for those who require fault tolerance and don’t need top-notch read performance. A … Continue reading






What is RAID 0 and its features, advantage and disadvantage?

RAID Level 0 Definition: RAID 0, or Redundant Array of Independent Disks, Level 0 – also called striping – is a method of storing data on multiple computer storage devices – usually hard disks or disk partitions – by interleaving the data and spreading it across the devices usually achieving faster read and write speeds. Common Name(s): RAID 0. (Note that the term “RAID 0” is sometimes used to mean not only the conventional striping technique described here but also other “non-redundant” ways of setting up disk arrays. Sometimes it is (probably incorrectly) used just to describe a collection of disks that doesn’t use redundancy.) Description: The simplest RAID level, RAID 0 should really be called “RAID”, since it involves no redundancy. Files are broken into stripes of a size dictated by the user-defined stripe size of the array, and stripes are sent to each disk in the array. Giving … Continue reading
