U-Vratislav Holub Isitatimende sephephandaba: I-QNAP® Systems, Inc. (QNAP) yethule ngokusemthethweni uhlelo lokusebenza QuTS iqhaweh4.5.2 ye-NAS. Ngokuthuthuka okuningana kunenguqulo yangaphambilini, iqhawe le-QuTS h4.5.2 lengeza ukusekelwa kwe-SnapSync ngesikhathi sangempela ukuze kutholakale ukuvumelanisa idatha ukuze wenze ikhophi yasenqolobaneni yedatha ebalulekile, kanye ne-algorithm enelungelo lobunikazi ye-QSAL (QNAP SSD Antiwear Leveling) ukuvimbela ukwehluleka ngesikhathi esisodwa kokuningi. Ama-SSD okuvikela idatha ephezulu kanye nesistimu yokwethembeka.
Qinisekisa ukuvikeleka kwedatha okuphelele nge-SnapSync yesikhathi sangempela
Iqhawe le-QuTS lisekelwe ku-128-bit Uhlelo lwefayela le-ZFS, egcizelela ubuqotho bedatha futhi inikeza idatha yokuziphilisa, okuyenza ifaneleke ezitolo zedatha yebhizinisi ezidinga ukuvikelwa kwedatha okusebenzayo. Ukuqinisekisa ukutholwa kwenhlekelele okungaguquki kanye nokuvikelwa kwe-ransomware, iqhawe le-QuTS lisekela cishe inani elingenamkhawulo lezifinyezo, okuvumela ukuhumusha kwesifinyezo esilinganiselwe. Ubuchwepheshe bokukopisha kokuthi Bhala kuvumela izithombe ukuthi zidalwe cishe ngokushesha ngaphandle kokuthikameze idatha ebhalwayo. Ubuchwepheshe be-block yesikhathi sangempela obuthuthukisiwe be-SnapSync buvumelanisa ngokushesha izinguquko zedatha nesitoreji esiqondiwe ukuze amadivayisi ayinhloko nawesibili e-NAS ahlale egcina idatha efanayo, eqinisekisa ukutakula kwenhlekelele ngesikhathi sangempela nge-RPO encane futhi kungabikho ukulahleka kwedatha.
Vimbela ama-SSD amaningi ekuhlulekeni kanyekanye ne-QSAL
Njengoba ukusetshenziswa kwama-SSD kwanda, amabhizinisi kufanele alungiselele ingozi enkulu yokulahleka kwedatha ngenxa yobunzima bokuthola idatha ku-SSD efile. I-algorithm ye-QSAL ivamise ukuthola isikhathi sokuphila nokuqina kwe-SSD RAID. Lapho impilo ye-SSD isiku-50% wokugcina, i-QSAL izosabalalisa indawo yokusetshenziswa ngokweqile ukuze kuqinisekiswe ukuthi i-SSD ngayinye inesikhathi esanele sokwakha kabusha ngaphambi kokuba ifinyelele ekupheleni kwempilo. Lokhu kungavimbela ngempumelelo ukwehluleka ngesikhathi esisodwa kwama-SSD amaningi futhi kuthuthukise ukwethembeka kwalo lonke uhlelo. I-QSAL inomthelela omncane ekusetshenzisweni kwendawo yokugcina, kodwa ithuthukisa ngokuphawulekayo ukuvikelwa kwedatha kukonke kokugcinwa kwe-flash.
Ezinye izici ezibalulekile zeqhawe le-QuTS:
- Inqolobane yokufundwa kwenkumbulo eyinhloko (L1 ARC), inqolobane yokufunda yezinga lesibili le-SSD (L2 ARC) kanye ne-ZFS Intent Log (ZIL) yokwenziwayo okuvunyelanisiweyo ngokuvikela ukwehluleka kwamandla ekusebenzeni okuthuthukile nokuphepha.
- Isekela umthamo ongafika ku-petabyte engu-1 kumafolda abelwe ngamanye.
- Isekela ukuphathwa komdabu kwamazinga e-RAID ajwayelekile nezinye izakhiwo ze-ZFS RAID (RAID Z) kanye nesakhiwo sesitaki sesitoreji esivumelana nezimo. I-RAID Triple Parity kanye ne-Triple Mirror iqinisekisa amazinga aphezulu okuvikelwa kwedatha.
- Vimba ukuncishiswa kwedatha esemgqeni, ukuminyanisa nokunciphisa usayizi wefayela ukuze wonge isikhala sokulondoloza, uthuthukise ukusebenza kuyilapho ukhulisa ubude besikhathi sokuphila kwe-SSD.
- Isekela ukulayishwa okuzenzakalelayo kwe-WORM WORM (Bhala Kanye, Funda Okuningi) isetshenziselwa ukuvimbela ukuguqulwa kwedatha egciniwe. Idatha ekwabiweni kwe-WORM ingabhalelwa kuphela futhi ayikwazi ukususwa noma ilungiswe ukuze kuqinisekiswe ubuqotho bedatha.
- Ukusheshiswa kwezingxenyekazi zekhompuyutha ze-AES-NI kukhulisa ukusebenza kahle kokusayinda idatha kanye nokubethela/ukukhishwa kwemfihlo nge-SMB 3.
- Ihlinzeka ngeSikhungo Sohlelo Lokusebenza esinezinhlelo zokusebenza ezidingekayo ukuze i-NAS ikwazi ukusingatha imishini neziqukathi ezibonakalayo, yenza izipele zendawo/ekude/ifu, idale amasango okugcina amafu, nokunye okuningi.
