Mhedzisiro yebvunzo dzekuita kwepurojekiti yeReiser5 yakaburitswa, iyo inovandudza yakanyatsogadziridzwa vhezheni yeReiser4 faira system nerutsigiro rwemavhoriyamu ane musoro ane "parallel scaling", iyo, kusiyana neyakajairwa RAID, inoreva kushanda nesimba kwefaira system. mukugovera data pakati pemidziyo yezvikamu zvevhoriyamu inonzwisisika. Kubva pakuona kwemaneja, musiyano wakakosha kubva kuRAID ndewekuti zvikamu zvehumwe hunoenderana-mwero inonzwisisika vhoriyamu yakafomatirwa block zvishandiso.
Mhedzisiro yebvunzo yakapihwa inoongorora mashandiro emafaira akajairwa, sekunyora faira kune vhoriyamu ine musoro, kuverenga faira kubva pavhoriyamu inonzwisisika inoumbwa nenhamba inosiyana yeakasimba-state madhiraivha. Kuita kwekushanda pamavhoriyamu anonzwisisika, akadai sekuwedzera mudziyo kune vhoriyamu inonzwisisika, kubvisa mudziyo kubva kune inonzwisisika vhoriyamu, kugadzirisa zvakare data kubva kune proxy disks, uye kutamisa data kubva kune yakajairwa (isina yakakosha) faira kuenda kune yakatarwa mudziyo, yaive zvakare. kuyerwa.
Solid-state drives (SSD) muhuwandu hwemakopi mana akashandiswa kuunganidza mavhoriyamu. Kumhanya kwekuvhiya pavhoriyamu inonzwisisika inotsanangurwa seyero yehuwandu hwenzvimbo yakagarwa pavhoriyamu yese inonzwisisika kusvika panguva yainotora kupedzisa kuvhiyiwa, kusanganisira kuenderana kuzere nemadhiraivha.
Iko kumhanya kwechero mashandiro (kunze kwekutsvaira data kubva kune proxy disk pavhoriyamu inoumbwa nenhamba shoma yemidziyo) yakakwirira kupfuura kumhanya kwekukopa data kubva kune chimwe chishandiso kuenda kune chimwe. Panguva imwecheteyo, nekuwedzera kwenhamba yezvishandiso kubva kune iyo vhoriyamu inoumbwa, kukurumidza kwekushanda kunowedzera. Kunze kweiyo faira yekufambisa mashandiro, iyo yekumhanyisa iyo asymptotically inosvika (kubva kumusoro) kumhanya kwekunyora kune yakananga mudziyo.

Zvinocherechedzwa kuti kuita kunogona kuvandudzwa kana maitiro ekuburitsa zvikumbiro zveI/O akafananidzwa pazvikamu zvevhoriyamu ine musoro (ikozvino, kuitira kurerutsa, izvi zvinoitwa muchiuno neshinda imwe chete). Uye zvakare kana iwe ukaverenga chete iwo data ari pasi pekufamba panguva yekuenzanisa (ikozvino, kuti zvive nyore, data rese rinoverengwa). Iyo theoretical muganho wekukurumidza kwekuwedzera / kubvisa mudziyo wechipiri mumasisitimu ane parallel scaling inopetwa kaviri kumhanya kwekopi kubva kune yekutanga dhisiki kuenda kune yechipiri (zvichienderana, kubva kune yechipiri kusvika kune yekutanga).
