Pitanje u vezi ploce Gigabyte P35 DS3R (sta je ono "R")?

^{08.12.2008. u 06:34 - pre 187 meseci}

Imam plocu Gigabyte P35 DS3R (rev 2.0) i ne znam sta znaci ono R u oznaci?

Na sajtu proizvodjaca imam specifikacije (ono osnovno), ali ne mogu da nadjem tu informaciju.
Neko mi rece da to "R" ima neke veze sa RAID-om, ali nisam siguran da li ima veze i ako ima, kakve veze ima?

Konkretno, interesuje me KAKAV TACNO raid ova ploca podrzava? Evo lspci iz Linuxa kako izgleda i sta ima na njoj od kontrolera:

Ovde: http://www.xbitlabs.com/articl...rds/display/ga-p35-ds3r_3.html - sam nasao da ima RAID support, ali kog je tipa?

Tamo pise i ovako:

Citat:

Both, the integrated ICH9R ATA controller as well as Gigabyte SATA2 chip, allow creating RAID 0 and 1 arrays. ICH9R also supports RAID 0+1 and 5 arrays and Matrix Storage Technology.

- a ja, sudeci po izlazu komande iz linuxa, imam ICH9R - znaci kakve su mogucnosti ovog RAID-a i sta mu je taj Matrix Storage Tech. sto podrzava.

Zasto ovo pitam - pa imam jedan WD 250GB HDD (AAKS, 16mb cache, 7200rpm), i hteo bih da dodam jos jedan
identican takav (nije mnogo skup) i da kreiram brzinski raid (sigurnost podataka mi nije nesto bitna, bitnija mi je
brzina) - pa me zanima kako bih taj raid na ovoj ploci kreirao, i kako bi on radio.

Intel® Matrix Storage Manager

Citat:

Intel Matrix RAID
From Wikipedia, the free encyclopedia

Intel Matrix RAID is a RAID layout employing two physical hard disks in a single array, in which part of each disk is assigned to a RAID 0 volume, and the other part to a RAID 1 volume.

Matrix RAID first appeared in the Intel RAID BIOS based on the ICH6R "South Bridge" chipset.

Intel Matrix RAID is not a new RAID level.

Intel's recommended setup is to put the operating system, critical application programs and data on the RAID 1 volume. The thinking being that protection from losing the configured OS, programs and data is more important than a performance increase. The RAID 0 volume in Matrix RAID is promoted mostly for working with large files, such as videos during editing, and for non-critical files where fast storage will increase performance (swap files, for example).

"Take Five" is the famous jazz piece written by Paul Desmond and performed by The Dave Brubeck Quartet. It is famous for its distinctive saxophone line and use of the unusual quintuple (5/4) time, from which its name is derived.

Take Five (1966)

Take Five by Al Jarreau 1976

Da R oznaka na tvojoj ploci znaci da umesto ICH9 ima ICH9R Southbridge koji podrzava RAID 0 (STRIPE. To je ono sto ti hoces ako hoces da dobijes na brzini), RAID1 (MIRROR), RAID 0+1 (SRIPE niz u MIRROR nizu. Potrebno najmanje 4 harda.) i RAID 5 (STRIPE niz sa distribuiranim paritetom. Potrebno minimum 3 harda).

Za kreiranje hardverskog RAID 0 konsultuj uputstvo od ploce. Lako je. Ne znam kako se Ubuntu snalazi sa RAID nizovima.

Znaci - kada stavim jos jedan HDD od 250GB, onda ce mi se u BIOS-u pojaviti opcije za
namestanje RAID-a iz samog BIOS-a? Sad pretpostavljam da nema tih opcija jer imam samo
1 HDD. (imam najnoviji BIOS instaliran)

Cek jel to onda hardverski raid na ovoj ploci? Ili i dalje softver (nesto iz samog OS-a) mora da
podrzava to - ili sve radi taj chip na ploci?

Linux ce valjda videti to, mogu da probam, nista me ne kosta, ako bas ne bude moglo
koristicu diskove na klasican nacin.

Imas tih opcija i sad u BIOS-u. Kao sto rekoh konsultuj user manual ali citaj pazljivo :) Kad dodas jos jedan hard ako napravis RAID0 niz ne verujem da ce Linux na prvom hardu biti citav. Moraces ponovo da ga instaliras. Druga solucija je softverski RAID0 niz. Ne znam da li postoji ta mogucnost u Ubuntu Lindzi i nemam gde da proverim ni da hocu jer vise nemam instaliranih Linuxa :)

^ Joj, ma kakav citav linux na prvom hardu, ja ionako OS instaliram iz zezanja svako malo - malo :)
tako da je meni testiranje OS-eva i brisanje svih particija sa HDD-a k'o dobar-dan! :)

Naravno, odmah bi stavio ta dva diska, pobrisao sve particije na oba, podesio u BIOS-u RAID-0,
i ubacio Ubuntu Install CD :) - a onda bi video sta on "vidi" :)

Kada se dva diska od 250GB uvezu u RAID-0, koji je onda kapacitet (realan) u tom modu,
tako kreiranog "jednog" diska?

I da, da ponovim pitanje - to je onda hardverski raid, jel?
