RAID 0 in 1

RAID 0 in 1

OmegaM ::

Pozdravljeni!

Imam eno plato + 1 proc katero bi rad porabil se za en komp k vecjemu za delo, pa me nekaj zanima, plata je asus A7V600 imam gori 2 sata konektorja, katera mi omogoca funkcijo RAID 0 in 1, zanima me, ce sledece:

Razlika, med RAID 0 in 1, pa ali mi je vseeno katere diske vzamem za RAID polje. S tem mislim na enake proizvajalce, npr. Samsung 2x 160 giga disk SATA.

Zanima me tudi ali lahko kako nar edis particije in disk das v RAID.

Hvala in Lp

RAID 0: Striped Set (2 disks minimum) without parity. Provides improved performance and additional storage but no fault tolerance from disk errors or disk failure. Any disk failure destroys the array, which becomes more likely with more disks in the array. The reason a single disk failure destroys the entire array is because when data is written to a RAID 0 drive, the data is broken into fragments. The number of fragments is dictated by the number of disks in the drive. The fragments are written to their respective disks simultaneously on the same sector. This allows smaller sections of the entire chunk of data to be read off the drive in parallel, giving this type of arrangement huge bandwidth. When one sector on one of the disks fails, however, the corresponding sector on every other disk is rendered useless because part of the data is now corrupted. RAID 0 does not implement error checking so any error is unrecoverable. More disks in the array means higher bandwidth, but greater risk of data loss.

RAID 1: Mirrored Set (2 disks minimum) without parity. Provides fault tolerance from disk errors and single disk failure. Increased read performance occurs when using a multi-threaded operating system that supports split seeks, very small performance reduction when writing. Array continues to operate so long as at least one drive is functioning.

Aha, hvala PlaviRibon :D

Torej to kar hocem je nekako RAID 1, vendar kako je z particijami, da bi recimo disk razdelil na 2 dela, v tem primeru 2 enaka diska na 2 dela. Oz, na 4. Upam da sem razumljiv.

Ko si izmislis kaj bi rad in v BIOSu dolocis npr. RAID 1 za 2 diska. Bos potem v OSu videl samo 1 disk (RAID 1 polje) in potem delas naprej kot z navadnim diskom.

bluefish ::

pri RAID 1 lahko, če se ne motim, razdeliš le primarni disk, saj drugi služi za mirror kopijo prvega.

Tistega drugega dela vprašanja pa ne razumem najbolje.

kixs ::

Ko enkrat dolocis RAID polje, vidis celotno polje kot en disk!

V Raid 1, se avtomaticno klonirata diska in ti nimas nad tem nobenega nadzora. Kot receno, vidis v OSu (Windows, Linux) to RAID polje kot en disk. Ko naredis particije, se naredijo enako na vseh diskih v polju.

Ok, torej mislim da sem bil odgovor na vse
