Best Answer

Yes. RAID-5

• Fault-tolerant development of striped volume

• Parity stripe written to each disk in volume

• Parity for set of data always on separate disk from data within set

• If one disk fails possible to reconstruct data from If one disk fails, possible to reconstruct data from parity

• Minimum of 3 HD's required

• Storage efficiency improves as number of HD's increased

• Improvement in speed over single disk

What is RAID fault tolerance?

Fault tolerance is the ability of a system to continue working even when a fault exists. In the case of RAID, which stands for Redundant Array of Inexpensive Discs, fault tolerance is provided by having data recorded on more than one drive, and also by having more than one power supply. Note that RAID 0 is not fault telerant because it is simply stripes the data to increase size and bandwidth, but provides no redundancy. RAID 1 and RAID 5 are fault tolerant, to various levels.


What types of disk arrays provide the MOST fault tolerance?

RAID 6 provides the most fault tolerance of any standard RAID disk arrays (RAID 0, 1 , 5, 6, and RAID 10). If any two disks in a RAID 6 array fail and are removed, then two new blank disks can be installed and no data has been lost. RAID 1+1 or most other "layered" RAID systems can provide more fault tolerance than RAID 6, tolerating the failure of any 3 disks. Some experimental non-standard disk arrays can provide more fault tolerance with less overhead, such as the parchive system. Nearly all distributed file systems and distributed version control systems can be set up so that if one machine is completely destroyed by fire, all the data can be recovered from a backup machine in another building.


Which RAID level stripes data across multiple drives to improve performance?

Every RAID level stripes data across multiple drives, which improves performance compared to using a single disk. RAID 0, RAID 1, RAID 1+0, RAID 5, RAID 6, etc. all have better performance than a single disk. Other than RAID 0, all other RAID levels provide fault tolerance. RAID 1, RAID 1+0, RAID 5, RAID 6, etc. all have fault tolerance.

Which RAID level will you implement to provide redundancy?

Type your answer here...Answer Explanation: RAID 1 uses a minimum of two hard disks to mirror data for fault tolerance. Each hard disk contains a complete copy of the data. Disk duplexing improves mirroring because each disk is on a separate controller. If one disk or controller fails in a duplexing RAID 1 array, the other disk can take over immediately to provide fault tolerance.RAID 5, also known as disk stripping with parity, provides fault tolerance by striping the data across a minimum of three and a maximum of 32 disks, and by storing parity information on each disk. This allows the RAID array to recover from a single disk failure.RAID 0, also known as disk striping, is used to increase performance by striping data over a minimum of two and a maximum of 32 disks. RAID 0 provides no fault tolerance.RAID 3, also known as disk stripping with a parity disk, provides fault tolerance by writing data across three or more drives. Because the least number of hard disks is required, RAID 1 will be used instead of RAID 3.


Why does raid o not provide fault tolerance?

Different RAID systems have different effects on multiple hard drives. RAID 0 combines storage together. Say you have 2 250GB HDDs combined with RAID 0: that you gives you, essentially, 500GB of storage. The problem with RAID 0 is that if one of the drives were to fail, then the other is to fail too, because of the way RAID 0 works by distributing strands of data over both disks. RAID 0 is sometimes not considered to be a true RAID system because of the lack of fault tolerance. RAID 1 and 5 are more complex to describe, but they generally deal with the same thing: backups. Instead of combining storage, RAID 1 and 5 deal with clones of a particular drive to offer redundancy if one were to fail. Say you have 2 250GB HDDs under RAID 1, essentially giving you 250GB of storage. If one drive were to fail, then the other would serve as a replacement if such were to occur.


What is a fault tolerance measure known as disk striping with parity?

RAID-5 provides data redundancy by using parity. Parity is a calculated value used to reconstruct data after a failure. While data is being written to a RAID-5 volume, parity is calculated by doing an exclusive OR (XOR) procedure on the data. The resulting parity is then written to the volume.


Which method of fault tolerance is least expensive per MB of storage disk duplexing or disk striping with parity?

has to be raid 5. raid5 with the parity will consume about 1/3 of the disk space but will give just about the highest level of fault tolerance. raid0 - disk striping - will give you the full disk space but no fault tolerance raid1 - disk splitting/ duplexing - will give you full redundancy but will cost 50% of your disk space raid5 - parity - will do block-level striping with parity data , disk space cost about 30%, redundant
