Rondedzera faira okuchengetera mamiriro pamusoro disk. File System Organization

Kana uri kutsvaka ruzivo "Musoro pamusoro dhisiki faira okuchengetera hurongwa", ipapo muri kurudyi njanji! Chero date zviri kombiyuta yako kuti zvishandiswe akazotevera. Asi sei kushandisa mashandiro yakadaro? Zvakandiomera kana kwete?

Ndechipi faira chekuchengeta hurongwa

Pasi faira okuchengetera hurongwa anonzwisisa Hardware uye Software mhinduro zvainanga ndiko nechokwadi yakachengeteka kuchengetera mashoko ose iri. Vanogona kuita huru kana zvimwe chikamu muzinda date kugadzira. Ndizvo unogona kupindura, kana iwe akaisa basa: ". Tsanangura mafaira pamusoro dhisiki okuchengetera hurongwa" Kunze kubva mashoko pfupi, pane kunyange nenguva yakaoma zvikuru: protocols, mifananidzo, ano.

protocols

Mune date chekuchengeta uye yedzimudzangara dzakati anoshandisa zviitiko. Vamwe vari shoma kwazvo, apo vamwe dzakakurumbira chaizvo. Panguva iyoyo, aishingaira chinozoiswa iSCSI, saka nyaya Protocols chichaitwa musi muenzaniso wake. Michina iyi nechinangwa kushanda kuburikidza yenguva dzose rezvebonde kwezvivako. Kunoitawo kuti dzaiitirwa kune workstations kana servers kuti okuchengetera mano okushandisa Papera nenzira yakadai sokuti - zvakamisa hurongwa pakombiyuta. On zvakanakira munhu dzakati kwakadaro kunogona akati:

1. basa rake riri chisingakoshi, kana asina kusununguka (shareware).
2. The-software module yacho dzakati anogona kushanda anodawo zvose dzakakurumbira gadziriro. Mune dzimwe zvinonzi yakaiswa default, mune mamwe - uye inogona kutorwa kuti kombiyuta yako kuwedzera mazita protocols.
3. Operation zvinogoneka pakarepo mushure okuguma nokuwedzera kwacho.
4. Nokuti dzakati anoshandisa Internet kero, unogona kutapurira mashoko chero nzvimbo panyika apo pane nhau.

Rine iye hakungobatsiri, asiwo zvainovhiringidzawo. Kazhinji, ane chimwe chete drawback: nokusungwa kune Internet kero uye hazvibviri zvizere kushanda pasina izvozvo.

marudzi hurongwa

Munyika yanhasi, pasinei zvinodiwa vakashandisa 4 faira okuchengetera:

1. Das. Pasi naye kunzwisisa disks zvine chokuita kuti yekombiyuta zvakananga. Zvose zvakabatana PC wako zvakananga, shandisa ino.
2. Psalms. ino inozivikanwa mafeni zvemunzvimbo network. Inopa kuwana munyika mafaira uye magwaro chete zvave kuzivikanwa so "ake."
3. SAN. Kubva pfungwa nemaonero inodzidzisa anogona kutsanangura maitiro yomunzvimbo nemotokari, kuti izvo kubatana unoitwa kubva pomumbure kushandisa dzakati kuti dziri kure kuwana mafaira.
4. CAS. Izvi yokuchengetera zvinhu mavakirwo umo basa rinokosha iri kuridzwa ne mufananidzo zvakachengetwa mashoko. Ari hashed uye kushandiswa kutsvaka mashoko ari kudzosa gadziriro, kana munhu akaipa. Kutaura zvazviri, mapurani ichi inogona kuenzaniswa zvitsigiro inokosha umo computed hashi - chombo kuti nokukurumidza achisecha mukati. ino ndiyo nyore amenable kuti decentralization, izvo chaizvo inowedzera mukurumari uye rakavimbika. Asi nekuipira zvinosanganisira pamwero duku kuita kuti haabvumiri pamwero kurishandisa. Zvino akitekicha ichi rinoshandiswa senzira dzigare mairi Archived data, kana avo kuti vanofanira kuva inogara kwenguva refu.

Technology kushandiswa chitoro Data

Mukati hurongwa, pane nzira dzakawanda date okuchengetera kuti optimize dhisiki kushandiswa uye kuti inishuwarenzi kana kuti njodzi:

1. Negadziriro yeparutivi. Rinomirira netarisiro kusikwa makopi mashoko anogona kubviswa uye izvo kungadiwa zvakare. An rinokosha iri kuridzwa ne faira saizi. With zvizere redundancy kunokanganisa yose maitiro uye mafaira. With incremental kopi iri rakaramba chete chikamu chayo. Search Selection chinoitwa neavo kuti zvakachinja kubvira ndima rokupedzisira negadziriro yeparutivi. Kazhinji inochengetwa date ndiyo ngarurege C kana zvikurukuru vakasikirwa chinangwa ichi okuchengetera.
2. Kuberekana. Hazvina synchronous uye asynchronous. By kutanga kunzwisisa placement pamusoro data, vari dzakasiyana okuchengetera gadziriro (kunyange zvingava kushandisa Zvifambiso maviri chete ino). Panyaya iyi, zvinyorwa ruzivo rinoitwa panguva imwe chete. Asynchronous kuberekana ndiwo mashoko chinyorwa kuitwa kwete mumwe chete nguva, uye apo zvakakunakira. Izvi anotibvumira kukunda nokukurumidza musiyano, asi mashoko musambozvidya zvachose mungashandisa achaita. Kunyange zvazvo achaedza vakananga ichi. Achiedza sangana nayo akasikwa Semi-synchronous kuberekana michina. Chaizvoizvo Its iri ndechokuti zvinyorwa rinotanga kuitwa panguva imwe chete, asi akashandisa migero panguva zvizere chinzvimbo. Kana kumwe kwacho kunopera, mumwe ichiri kupera. The date iri akaparadzaniswa nevanhu kushoma.
3. Deduplication. A nzira chaiyo kuti compression Data mumitsetse anobvisa nouya makopi ose nouya mafaira. nzira zvikuru apo faira kopi Kukura uye nhamba yakakwirira chaizvo. Kushandiswa optimize kushandisa nzvimbo.

Asi haana mhinduro izere kuti dambudziko, "Ndapota rondedzera mafaira pamusoro dhisiki okuchengetera hurongwa." Kuti muedzwe yakazara vanofanira kufunga zvakawanda ndangariro.

verenga-chete ndangariro

Zvinonzwisiswa sezvo mashoko kuchengetwa, izvo haafaniri kuvimba nesimba zvitengeswa hurongwa. Uyewo, inonzi non-akadaro ndangariro. In kwemauto ichi, dzinounzwa dhisiki nzvimbo yokuchengetera faira mazita. Zvakakodzera kunzvera zvakachengetwa mashoko. vose "kugara" Anonziwo kuchengetwa pano mashoko ari wacho nokuda user. Somuenzaniso, mashoko anenge kushanda mafaira, mitambo, akaponesa zvinyorwa, folders. Muchigamuchira mashoko anogona kuwanikwazve kunyange pashure emakore, sezvo kurekodha uye simba achidzima kakawanda. Muenzaniso ndiyo C nemotokari iri iyo uchishandisa hurongwa mafaira. Pashure pezvose, sokunge kana vakanga riini? Kana zvaibvira kutanga kombiyuta? Pasina mamwe evanhu - kwete!

chibhubhubhu kuwana ndangariro

Pane operative kana akadaro ndangariro. peculiarity charo kuti zvinokosha kuitira chichiitwa magetsi. Panguva iyoyo zvinomirira kukura kombiyuta inogona kubata imwe nhamba nezviito, uye, chaizvoizvo, zvinokanganisawo pakukwanisa kwayo. Hazvina basa Zvifambiso, folders, mafaira uye magwaro kuti vava kushingaira uye kumhanya. Zvinofanira kucherechedzwa kuti usashandisa pasina kuwedzera kuyeuka kuvandudza kombiyuta Hardware kakawanda hwakazara kutyorwa mabasa yose ino (kwete okuchengetera).

cache ndangariro

Uyewo zvakanga inonzi nokukurumidza kuwana ndangariro. Rine mashoko kazhinji kuzodana. The peculiarity ndechokuti dzose, uye cache zvine chete mashoko. Asi nokuti kuti chechipiri nokukurumidza, Pakutanga akaita tsvakiridzo pamusoro payo. Kana pasina mutambo akawanikwa, kombiyuta achava kutarisa kuyeuka zvachose. Kana mutambo unowanikwa Maive kuchinja vachaitwa pano pakutanga. Zvino, kana zvichibvira, mune dzisiri akadaro ndangariro. A zvakafanana drawback pamusoro cache ndiko iduku kana ichienzaniswa. Kuchengeta mafaira pakombiyuta disks ndeyevanyori rokuti Hardware ose zvamarudzi ndangariro. Saka kana uchida kushandura kukura iiswe chinhu nani uye panguva imwecheteyo inowirirana dzimwe gadziriro.

mhedziso

Sezvaunogona kuona, kuti hurongwa okuchengetera - a nani kunzwisisa mashandiro. Anosanganisira siyana protocols (nomunhu chete aionekwa tichifunga siyana mashoko), marudzi akasiyana-siyana, sangano nzira uye ruzivo, uyewo nomusoro. Zvino tinogona kutaura kuti mhinduro chikumbiro "ritsanangure mafaira pamusoro dhisiki okuchengetera gadziriro" anopiwa.
