RAID 3D . Qhov no yog tswv RAID tsim los ntawm Pure Storage thiab siv flash drives es tsis txhob hard disks. Qhov no feem ntau yog siv los tiv thaiv cov ntaub ntawv poob thaum cov khoom tsis ua haujlwm hauv flash cia. Vim muaj kev hloov ceev ceev hauv lub xeev drives, cov array muaj kev ua haujlwm siab I / O.
Kuj tseem paub yog, RAID 3 ua haujlwm li cas?
RAID 3 yog Redundant Array ntawm Independent Disks ( RAID ) tus qauv uas siv striping ntawm qib byte thiab khw muag khoom parity khoom ntawm ib tug nyias muaj nyias disk drive. Zoo li RAID 2, RAID 3 yuav tsum muaj tus tswj tshwj xeeb uas tso cai rau synchronized spinning ntawm tag nrho cov disks.

Hauv luv luv qhov no txhais tau tias RAID 4 tsis strip cov ntaub ntawv ntawm qib thaiv tab sis nws siv byte qib rau striping (block-level striping nrog a tshwj xeeb parity disk).
Hauv qhov no, RAID yog dab tsi thiab nws ua haujlwm li cas?
RAID (Redundant Array of Inexpensive Disks lossis Drives, lossis Redundant Array ntawm Independent Disks) yog cov ntaub ntawv khaws cia virtualization thev naus laus zis uas sib txuas ntau lub cev disk tsav rau hauv ib lossis ntau qhov laj thawj rau cov hom phiaj ntawm cov ntaub ntawv rov ua dua, kev txhim kho kev ua haujlwm, lossis ob qho tib si.
Dab tsi yog hom RAID?
Feem ntau hom yog RAID 0 (striping), RAID 1 (mirroring) thiab nws cov variants, RAID 5 (distributed kev sib haum xeeb ), thiab RAID 6 (dual kev sib haum xeeb ). RAID theem thiab lawv cov ntaub ntawv sib koom ua ke yog tus qauv tsim los ntawm Lub Koom Haum Kev Lag Luam Kev Lag Luam (SNIA) hauv Common RAID Disk Drive Format (DDF) tus qauv.

Qhov muaj heuristic yog ib txoj kev puas siab puas ntsws uas pab peb txiav txim siab raws li nws yooj yim npaum li cas los coj ib yam dab tsi rau hauv siab. Tus neeg sawv cev heuristic yog ib txoj kev puas siab puas ntsws uas pab peb txiav txim siab los ntawm kev sib piv cov ntaub ntawv rau peb cov qauv kev puas hlwb
Daim ntawv teev kev sib pauv yog dab tsi thiab nws txoj haujlwm yog dab tsi?
Daim ntawv teev kev lag luam yog cov ntaub ntawv sib txuas ntawm txhua qhov kev hloov pauv hauv cov ntaub ntawv thaum cov ntaub ntawv tiag tiag muaj nyob rau hauv cov ntaub ntawv sib cais. Daim ntawv teev kev lag luam muaj cov ntaub ntawv txaus los tshem tawm tag nrho cov kev hloov pauv tau ua rau cov ntaub ntawv cov ntaub ntawv ua ib feem ntawm ib qho kev sib pauv
