Controller properties

i

Controller properties

In computing and especially in computer hardware, controller is a chip, an expansion card, or a stand-alone device that interfaces with a peripheral device. This may be a link between two parts of a computer (for example a memory controller that manages access to memory for the computer) or a controller on an external device that manages the operation of (and connection with) that device.

Expansion card form factor

In der Computertechnik ist der Formfaktor eine Angabe über Größe und Befestigungsmöglichkeiten eines Bauteils, das in einem Computer Verwendung findet. Durch diese Standardisierung können verschiedene Komponenten einfach zusammengefügt und ausgetauscht werden.

Low Profile

Als "Low Profile PCI Card" wird in der Computertechnik ein Formfaktor für PCI- bzw. PCIe-Steckkarten bezeichnet, der in bestimmten Gehäusen mit begrenztem Platz Anwendung findet.

RAID configuration
i

RAID configuration

RAID (redundant array of independent disks, originally redundant array of inexpensive disks) is a storage technology that combines multiple disk drive components into a logical unit. Data is distributed across the drives in one of several ways called "RAID levels", depending on what level of redundancy and performance (via parallel communication) is required.

0
i

0

(block-level striping without parity or mirroring) has no (or zero) redundancy. It provides improved performance and additional storage but no fault tolerance.

1
i

1

(mirroring without parity or striping), data are written identically to two drives, thereby producing a "mirrored set"; the read request is serviced by either of the two drives containing the requested data, whichever one involves least seek time plus rotational latency.

5
i

5

(block-level striping with distributed parity) distributes parity along with the data and requires all drives but one to be present to operate; the array is not destroyed by a single drive failure.

6

Ein RAID-60-Verbund besteht aus einem RAID-0-Array, das mehrere RAID 6 kombiniert. Hierzu sind mindestens zwei Controller mit je vier Festplatten, also gesamt acht Festplatten, notwendig. Prinzipiell skalieren sich die Unterschiede von RAID 5 und RAID 6 hoch auf die Unterschiede zwischen RAID 50 und RAID 60: Der Durchsatz ist geringer, während die Datensicherheit höher ist. Der gleichzeitige Ausfall von zwei beliebigen Laufwerken ist jederzeit ohne Datenverlust möglich; weitere Ausfälle sind nur dann unkritisch, wenn maximal zwei Platten je gestriptem RAID 6 betroffen sind.

10

Ein RAID-10-Verbund ist ein RAID 0 über mehrere RAID 1. Es werden dabei die Eigenschaften der beiden RAIDs kombiniert: Sicherheit und gesteigerte Schreib-/Lesegeschwindigkeit.
Ein RAID-10-Verbund benötigt mindestens vier Festplatten.

50

Ein RAID-50-Verbund besteht aus einem RAID-0-Array, das aus mehreren striped RAID 5 besteht.
Ein RAID-50-Verbund benötigt mindestens sechs Festplatten, beispielsweise zwei RAID-5-Controller mit jeweils drei Platten pro Controller zusammengeschaltet mit einem Software-Stripe RAID 0. Das garantiert einen sehr hohen Datendurchsatz beim Schreiben und Lesen, da die Rechenarbeit auf zwei XOR-Units verteilt wird.
Ein RAID-50-Verbund wird bei Datenbanken verwendet, bei denen Schreibdurchsatz und Redundanz im Vordergrund stehen.

Hot Spare
i

Hot Spare

A hot spare or hot standby is used as a failover mechanism to provide reliability in system configurations. The hot spare is active and connected as part of a working system. When a key component fails, the hot spare is switched into operation. More generally, a hot standby can be used to refer to any device or system that is held in readiness to overcome an otherwise significant start-up delay.

Native Command Queuing
i

Native Command Queuing

In computing, Native Command Queuing (NCQ) is an extension of the Serial ATA protocol allowing hard disk drives to internally optimize the order in which received read and write commands are executed. This can reduce the amount of unnecessary drive head movement, resulting in increased performance (and slightly decreased wear of the drive) for workloads where multiple simultaneous read/write requests are outstanding, most often occurring in server-type applications.
