A logical block number i of a volume maps to the same block number i on each mirrored plex. Mirrored storage with two mirrors Atto FibreBridge 2370E to RAID-1 storage explained in further detail below. Mirrored storage capacity does not scale—the total storage capacity of a mirrored volume is equal to the storage capacity of one plex.

Another type of storage uses RAID redundant array of independent disks; originally redundant array Atto FibreBridge 2370E inexpensive disks. RAID storage is a way of storing the same data in different places thus, redundantly on multiple hard disks. Since multiple disks increase the mean time between failure MTBFstoring data redundantly also increases fault-tolerance.

A RAID appears to the operating system to be a single logical hard disk.

RAID employs the technique of striping, which involves partitioning each drive's storage space into units ranging from a sector bytes up to several megabytes. The stripes of Atto FibreBridge 2370E the disks are interleaved and addressed in order.

Striped storage, as described above, is also referred Atto FibreBridge 2370E as RAID-0 storage, which is explained in further detail below. In a single-user system where large records, such as Atto FibreBridge 2370E or other scientific images, are stored, the stripes are typically set up to be small such as bytes so that a single record spans all disks and can be accessed quickly by reading all disks at the same time.


In a multi-user system, better performance requires establishing a stripe wide enough to hold the typical or maximum size record. Several types of RAID storage are described Atto FibreBridge 2370E. RAID-0 storage has striping but no redundancy of data.

RAID-0 storage offers the best performance but no fault-tolerance. RAID-1 storage is also known as disk mirroring and consists of at least two drives that duplicate the storage of data. There is no striping.

Read performance is improved since either disk can be read at the same time. Write performance is the same as for single disk storage.

RAID-1 storage provides the best performance and the best fault-tolerance in a multi-user system. RAID-3 storage uses striping and dedicates one subdisk to storing parity information.

Embedded error checking information is used to detect errors. Data recovery is accomplished by calculating the exclusive OR XOR of the information recorded on the other subdisks. For this reason, RAID-3 storage works well for single-user systems with data stored in long data records. Atto FibreBridge 2370E stripe is read or written in its entirety.

Striped plex [] includes subdisks d through d Subdisks d through d store data in stripes 4 - Atto FibreBridge 2370E4 - 2 and 4 - 3and subdisk d stores parity data in parity blocks P through P The logical view Atto FibreBridge 2370E plex is that data blocks 4 - 0 through 4 - 11 are stored in sequence. RAID-5 storage includes a rotating parity array, thus allowing all read and write operations to be overlapped.

RAID-5 stores parity information but not redundant data because parity information can be used to reconstruct data. RAID-5 typically requires at least three and usually five disks for the array. RAID-5 storage works well for multi-user systems in which performance is not critical or which do few write operations.

RAID-5 differs from RAID-3 in that the parity is distributed over different subdisks for different stripes, and a stripe can be read or written partially. Each of subdisks d through d stores some of the data in stripes 5 - 15 - 2 and Atto FibreBridge 2370E - 3. Subdisks ddand d store parity blocks P through P The logical view of plex is that data blocks 5 - 0 through 5 - 11 are stored in sequence.

In this example, two striped storage plexes of equal capacity, Atto FibreBridge 2370E [] A and B, are mirrors of each other and form a single volume Each of plexes A and B provides large capacity and performance, and mirroring provides higher Atto FibreBridge 2370E. Typically, each plex in a mirrored-stripe storage configuration resides on a separate disk array.
