Kwiinyanga ezimbalwa ezidlulileyo, uRadix wayenethuba lokusebenza kunye ne-Seagate EXOS drives yamva nje, eyilelwe imisebenzi yodidi lweshishini. Uphawu lwabo olwahlukileyo lulele kwisixhobo se-hybrid drive - idibanisa itekhnoloji yesiqhelo se-hard drives (yokugcina okuphambili) kunye ne-slid-state drives (yokugcina idatha eshushu).
Sele sinamava alungileyo sisebenzisa iidrive ezixutyiweyo ezisuka eSeagate njengenxalenye yeenkqubo zethu - kwiminyaka embalwa edlulileyo siye sasebenzisa isisombululo kwiziko ledatha labucala kunye neqabane elisuka eMzantsi Korea. Emva koko i-benchmark ye-Oracle Orion isetyenziswe kwiimvavanyo, kwaye iziphumo ezifunyenweyo zazingekho ngaphantsi kwe-All-Flash arrays.
Kweli nqaku siza kujonga indlela i-Seagate EXOS eqhuba ngayo ngetekhnoloji yeTurboBoost eyilwe, ivavanye amandla abo kwimisebenzi kwicandelo leshishini, kunye nokusebenza kovavanyo phantsi kwemithwalo edibeneyo.
Imisebenzi yecandelo loshishino
Kukho uluhlu oluzinzile ngakumbi okanye olungaphantsi lwemisebenzi enokuthi ibekwe njengemisebenzi yokugcina idatha kwi-corporate (okanye ishishini) segment. Ezi ngokwesiko ziquka: ukusebenza kwezicelo zeCRM kunye neenkqubo ze-ERP, ukusebenza kweposi kunye neeseva zefayile, ukugcinwa kunye nokusebenza ngokubonakalayo. Ukusuka kwindawo yokujonga inkqubo yokugcina, ukuphunyezwa kwemisebenzi enjalo kubonakaliswe ukuhamba komthwalo odibeneyo, kunye nobukhulu obucacileyo bezicelo ezingahleliwe.
Ukongezelela, iindawo ezinobuncwane ezifana ne-multidimensional analytics OLAP (i-Online Analytical Processing) kunye ne-real-time transaction process (OLTP, i-Online Transaction Processing) ziphuhlisa ngokusebenzayo kwicandelo leshishini. Into engaqhelekanga yabo kukuba bathembele ngakumbi kwimisebenzi yokufunda kunakwimisebenzi yokubhala. Umsebenzi abawenzayo-imithombo yedatha enzulu kunye neebhloko ezincinci-zifuna ukusebenza okuphezulu kwinkqubo.
Indima yayo yonke le misebenzi ikhula ngokukhawuleza. Bayeka ukuba ziibhloko ezincedisayo kwiinkqubo zokudala ixabiso kwaye bahambe baye kwicandelo lamacandelo aphambili emveliso. Kwiintlobo ezininzi zoshishino, oku kuba yinxalenye ebalulekileyo yokwakha inzuzo yokhuphiswano kunye nokuzinza kwemarike. Emva koko, oku kwandisa kakhulu iimfuno zeziseko ze-IT zeenkampani: izixhobo zobugcisa kufuneka zibonelele ngokugqithisayo kunye nexesha elincinci lokuphendula. Ukuqinisekisa ukusebenza okufunekayo kwiimeko ezinjalo, khetha iinkqubo ze-All-Flash okanye iinkqubo zokugcina ezixubileyo okanye ukudinwa.
Ukongezelela, kukho enye into ephawulekayo yecandelo lezoshishino - iimfuno ezingqongqo zokuphumelela kwezoqoqosho. Kucace gca ukuba ayizizo zonke izigqeba zeshishini ezinakho ukuthenga kunye nokugcinwa kwe-All-Flash arrays, ngoko ke iinkampani ezininzi kufuneka zincame kancinci ekusebenzeni, kodwa zithenge izisombululo ezingabizi kakhulu. Ezi meko zitshintsha ngamandla ugqaliselo lwemarike kwizisombululo ezixubeneyo.
Umgaqo weHybrid okanye iteknoloji yeTurboBoost
Umgaqo wokusebenzisa itekhnoloji ye-hybrid ngoku uyaziwa kubaphulaphuli abaninzi. Uthetha malunga nokwenzeka kokusebenzisa itekhnoloji eyahlukeneyo ukufumana izibonelelo ezongezelelweyo kwisiphumo sokugqibela. Iinkqubo zokugcinwa kwe-Hybrid zidibanisa amandla okuqhuba okuqinileyo kunye ne-classic hard drives. Ngenxa yoko, sifumana isisombululo esilungisiweyo, apho icandelo ngalinye lisebenza kunye nomsebenzi walo: i-HDD isetyenziselwa ukugcina inani elikhulu ledatha, kwaye i-SSD isetyenziselwa ukugcina okwesikhashana "idatha eshushu".
Ngokutsho , kummandla we-EMEA malunga ne-45.3% yemarike yenziwe ngeenkqubo zokugcina ezixubileyo. Oku kuthandwa kumiselwe kukuba, nangona ukusebenza okuthelekisayo, iindleko zeenkqubo ezinjalo ziphantsi kakhulu kunezisombululo ezisekelwe kwi-SSD, kwaye ixabiso le-IOps nganye lihamba ngasemva ngemiyalelo emininzi yobukhulu.
Umgaqo ofanayo we-hybrid ungaphunyezwa ngokuthe ngqo kwinqanaba lokuqhuba. I-Seagate yaba ngowokuqala ukuphumeza le ngcamango ngendlela ye-SSHD (i-Solid State Hybrid Drive) yeendaba. Iidiski ezinjalo ziye zafumana ukuthandwa okuhambelanayo kwimarike yabathengi, kodwa aziqhelekanga kakhulu kwicandelo le-b2b.
Isizukulwana sangoku sale teknoloji eSeagate singena phantsi kwegama lentengiso iTurboBoost. Kwicandelo leenkampani, inkampani isebenzisa itekhnoloji yeTurboBoost kumgca we-Seagate EXOS wokuqhuba, oye wanyusa ukuthembeka kunye nokudibanisa okufanelekileyo kokusebenza kunye nokusebenza kakuhle. Inkqubo yokugcina ihlanganiswe ngesiseko saloo diski iya kuthi, ngokweempawu zayo zokugqibela, ihambelane nokucwangciswa kwe-hybridi, ngelixa i-caching yedatha "eshushu" ivela kwinqanaba lokuqhuba kwaye lenziwa ngokusebenzisa amandla e-firmware.
I-Seagate EXOS drives isebenzisa i-16 GB eyakhelwe-ngaphakathi eMLC (Enterpise Multi-Level Cell) imemori ye-NAND ye-cache ye-SSD yendawo, enomthombo ophezulu kakhulu wokubhala kwakhona kune-MLC yecandelo labathengi.
Usetyenziso olwabiweyo
Emva kokuba sifumene i-8 Seagate EXOS 10E24000 1.2 TB drives esinayo, sagqiba ekubeni sivavanye ukusebenza kwabo njengenxalenye yenkqubo yethu esekelwe kwi-RAIDIX 4.7.
Ngaphandle, i-drive enjalo ibonakala njenge-HDD eqhelekileyo: i-2,5-intshi yensimbi yecala kunye neleyibhile enegama kunye nemingxuma esemgangathweni ye-fasteners.
I-drive ixhotywe nge-3 Gb / s i-SAS12 interface, evumela ukuba isebenze ngokufanelekileyo kunye nabalawuli ababini benkqubo yokugcina. Kukwafanelekile ukuqaphela ukuba olu jongano lunobunzulu bomgca omkhulu kune-SATA3.
Qaphela ukuba kumbono wolawulo, idisk enjalo kwinkqubo yokugcina ibonakala iyindawo eyodwa apho indawo yokugcina ingahlukaniswanga kwiindawo ze-HDD kunye ne-SSD. Oku kuphelisa imfuno ye-cache ye-SSD yesofthiwe kwaye yenza lula uqwalaselo lwenkqubo.
Njengemeko yesicelo sesisombululo esele senziwe, umsebenzi kunye nomthwalo ovela kwizicelo eziqhelekileyo zeenkampani zaqwalaselwa.
Inzuzo ephambili elindelekileyo kwisistim sokugcina esidaliweyo kukusebenza kokusebenza kwimithwalo edibeneyo kunye ne-predominance yemisebenzi yokufunda. Iinkqubo zokugcina ezichazwe kwisoftware ye-RAIDIX zibonelela ngokusebenza okuphezulu kokulandelelana komsebenzi, ngelixa i-Seagate iqhuba nge-TurboBoost itekhnoloji inceda ukwandisa ukusebenza komthwalo ongaqhelekanga.
Kwimeko ekhethiweyo, kubonakala ngathi: ukusebenza kakuhle kunye nemithwalo engahleliweyo evela kugcino-lwazi kunye neminye imisebenzi yesicelo iya kuqinisekiswa yizinto ze-SSD, kwaye iinkcukacha zesoftware ziya kuvumela ukugcina isantya esiphezulu sokucwangcisa imithwalo elandelelanayo ukusuka ekubuyiselweni kwedatha okanye ukulayishwa kwedatha.
Ngexesha elifanayo, yonke inkqubo ibonakala inomtsalane ngokwexabiso kunye nokusebenza: okungabizi (ngokumalunga ne-All-Flash) i-hybrid drives idibanisa kakuhle kunye nokuguquguquka kunye nokuphumelela kweendleko zeenkqubo zokugcina ezichazwe kwi-software eyakhelwe kwi-hardware ye-server eqhelekileyo.

isiphelo
Ukuqhuba ngeteknoloji yeTurboBoost kuvula amathuba amatsha kubasebenzisi kunye nabavelisi benkqubo yokugcina. Ukusebenzisa i-cache ye-SSD yasekhaya kwandisa kakhulu ukusebenza kwenkqubo ngokunyuka okuncinci kwiindleko zokuthenga iidrives.
Uvavanyo lweSeagate drives lwenziwe ngaphakathi ubonise umgangatho ophezulu wokuzithemba kwipatheni yomthwalo odibeneyo (70/30), ukulinganisa iimfuno eziqikelelweyo zemisebenzi esetyenzisiweyo kwicandelo lenkampani. Kwangaxeshanye, ukusebenza kwaphunyezwa amaxesha angama-150 ngaphezulu komlinganiselo wexabiso le-HDD drives. Kuyafaneleka ukuba uqaphele apha ukuba iindleko zokuthengwa kweenkqubo zokugcinwa kolu lungelelwaniso malunga ne-60% yeendleko zokuthelekisa isisombululo se-All-Flash.
