Mwedzi mishoma yapfuura, Radix akawana mukana wekushanda neazvino Seagate EXOS madhiraivha, akagadzirirwa bhizinesi-kirasi mabasa. Chinhu chavo chinosiyanisa ndeye hybrid drive mudziyo - inosanganisa matekinoroji eakajairwa madhiraivha akaomarara (yekuchengetera kukuru) uye akasimba-nyika madhiraivha (ye caching inopisa data).
Takatove neruzivo rwakanaka rwekushandisa mahybrid drives kubva kuSeagate sechikamu chemasisitimu edu - makore akati wandei apfuura takashandisa mhinduro yenzvimbo yakavanzika yedata pamwe chete nemudiwa wekuSouth Korea. Ipapo iyo Oracle Orion bhenji yakashandiswa mubvunzo, uye mhedzisiro yakawanikwa yakanga isiri yakaderera kune All-Flash arrays.
Muchikamu chino tichatarisa kuti Seagate EXOS inotyaira sei neTurboBoost tekinoroji yakagadzirwa, ongorora kugona kwavo kwemabasa muchikamu chekambani, uye bvunzo kuita pasi pemitoro yakasanganiswa.
Mabasa echikamu chekambani
Iko kune yakawedzera kana kushoma yakagadzikana yemabasa ayo anogona kudomwa semabasa ekuchengetedza data muchikamu chekambani (kana bhizinesi). Izvi zvinogara zvichisanganisira: kushanda kweCRM zvikumbiro uye ERP masisitimu, kushanda kwetsamba uye faira maseva, backup uye virtualization mashandiro. Kubva pane imwe nzvimbo yekuchengetedza, kushandiswa kwemabasa akadaro kunoratidzwa nekuyerera kwemutoro wakavhenganiswa, nehukuru hwakajeka hwezvikumbiro zvisinganzwisisiki.
Pamusoro pezvo, nzvimbo dzinowedzera zviwanikwa senge multidimensional analytics OLAP (Online Analytical Processing) uye real-time transaction process (OLTP, Online Transaction Processing) vari kushingaira kusimudzira muchikamu chebhizinesi. Chinhu chavo ndechekuti vanovimba zvakanyanya nekuverenga mabasa pane kunyora mabasa. Basa ravanogadzira-yakadzika data hova ine diki block sizes-inoda kushanda kwepamusoro kubva kuhurongwa.
Basa remabasa ose aya riri kukurumidza kuwedzera. Ivo vanorega kuva mabhuroko ebetsero mumaitiro ekugadzira kukosha uye kuenda muchikamu chezvikamu zvakakosha zvechigadzirwa. Kune akawanda marudzi ebhizinesi, ichi chinova chikamu chakakosha chekuvaka mukana wekukwikwidza uye kusimba kwemusika. Nekudaro, izvi zvinowedzera zvakanyanya zvinodikanwa zvemakambani eIT masisitimu: tekinoroji michina inofanirwa kupa yakanyanya kupinza uye shoma yekupindura nguva. Kuti uve nechokwadi chekuita kunodiwa mumamiriro ezvinhu akadai, sarudza All-Flash masisitimu kana mahybrid ekuchengetedza masisitimu ane kana kuneta.
Uye zvakare, pane chimwe chinhu chinobatika chechikamu chebhizinesi - zvakaomesesa zvinodiwa zvehupfumi hwehupfumi. Zviripachena kuti hazvisi zvese zvimiro zvemakambani zvinokwanisa kutenga nekuchengetedza All-Flash arrays, saka makambani mazhinji anofanirwa kukanda mapfumo pasi mukuita, asi kutenga akawanda-anodhura mhinduro. Aya mamiriro ari kushandura zvakanyanya musika kutarisa kune mahybrid mhinduro.
Hybrid musimboti kana TurboBoost tekinoroji
Nheyo yekushandisa tekinoroji yakasanganiswa ikozvino inozivikanwa kune vakawanda vateereri. Anotaura nezve mukana wekushandisa tekinoroji dzakasiyana kuwana mamwe mabhenefiti mumhedzisiro yekupedzisira. Hybrid kuchengetedza masisitimu anosanganisa kusimba kweakasimba-nyika madhiraivha uye ekirasi hard drive. Nekuda kweizvozvo, tinowana mhinduro yakagadziridzwa, iyo chikamu chimwe nechimwe chinoshanda nebasa rayo: HDD inoshandiswa kuchengetedza huwandu hukuru hwe data, uye SSD inoshandiswa kuve nechinguva "hot data".
Maererano ne , mudunhu reEMEA ingangoita 45.3% yemusika inogadzirwa neyakasanganiswa yekuchengetedza masisitimu. Kukurumbira uku kunotemerwa nenyaya yekuti, kunyangwe kuita kwekuenzanisa, mutengo wemasisitimu akadaro wakadzikira zvakanyanya kupfuura iwo eSSD-based mhinduro, uye mutengo weiyo yega IOps inosarira kumashure nemirairo yakati wandei yehukuru.
Iyo imwechete hybrid musimboti inogona kuitwa yakananga padanho rekutyaira. Seagate yaive yekutanga kuita iyi pfungwa muchimiro cheSSHD (Solid State Hybrid Drive) midhiya. Madhisiki akadaro akawana mukurumbira mumusika wevatengi, asi haana kunyanya kuwanda muchikamu cheb2b.
Chizvarwa chazvino cheiyi tekinoroji paSeagate inoenda pasi pezita rekutengesa TurboBoost. Kune chikamu chekambani, kambani inoshandisa tekinoroji yeTurboBoost muSeagate EXOS mutsara wemadhiraivha, ayo akawedzera kuvimbika uye musanganiswa wakakwana wekuita nekubudirira. Iyo yekuchengetedza system yakaunganidzwa pahwaro hwemadhisiki akadaro, maererano nehunhu hwayo hwekupedzisira, inoenderana neyakasanganiswa gadziriso, nepo caching ye "hot" data inoitika padanho rekutyaira uye inoitwa uchishandisa iyo firmware kugona.
Seagate EXOS madhiraivha anoshandisa 16 GB yeakavakirwa-mukati eMLC (Enterpise Multi-Level Cell) NAND ndangariro yemunharaunda SSD cache, iyo ine yakanyanya kukwirira kunyorazve sosi pane yevatengi-chikamu MLC.
Shared utility
Sezvo tagamuchira 8 Seagate EXOS 10E24000 1.2 TB madhiraivha atiinawo, takasarudza kuyedza kuita kwavo sechikamu chehurongwa hwedu hwakavakirwa paRAIDIX 4.7.
Kunze, dhiraivha yakadaro inoita seyakajairwa HDD: 2,5-inch simbi kesi ine branded label uye yakajairwa maburi emafasteners.
Iyo drive ine 3 Gb / s SAS12 interface, ichiibvumira kuti ishande nemazvo neaviri ekuchengetedza system controller. Izvo zvakakoshawo kuziva kuti iyi interface ine kudzika kwemutsara kwakakura kupfuura SATA3.
Cherechedza kuti kubva pakuona kwehutungamiri, dhisiki yakadaro mugadziriro yekuchengetedza inoratidzika kuva imwe svikiro umo nzvimbo yekuchengetedza haina kugoverwa muHDD uye SSD nzvimbo. Izvi zvinobvisa kudiwa kwesoftware SSD cache uye inorerutsa masisitimu ehurongwa.
Sechiitiko chekunyorera chemhinduro yakagadzirwa-yakagadzirirwa, shanda nemutoro kubva kune zvakajairwa zvikumbiro zvekambani zvakatariswa.
Iyo huru inotarisirwa kubatsirwa kubva kune yakasikwa yekuchengetedza sisitimu ndiko kugona kwekushanda pamitoro yakasanganiswa ine predominance yekuverenga mashandiro. RAIDIX software-yakatsanangurwa ekuchengetedza masisitimu inopa kushanda kwepamusoro kune anotevedzana mabasa, nepo Seagate inotyaira neTurboBoost tekinoroji inobatsira kukwirisa mashandiro ekusarongeka kwemabasa.
Kune iyo yakasarudzwa mamiriro, inoita senge iyi: kugona kwekushanda nemitoro isina kurongeka kubva kune dhatabhesi uye mamwe mabasa ekushandisa anozovimbiswa neSSD zvinhu, uye iwo chaiwo esoftware anobvumira kuchengetedza kumhanya kwakanyanya kwekugadzirisa mitoro inoteedzana kubva kudzoreredza database kana. kurodha data.
Panguva imwecheteyo, iyo yese sisitimu inotaridzika inokwezva maererano nemutengo uye mashandiro: isingadhure (inoenderana neAll-Flash) madhiraivha akasanganiswa akabatana zvakanaka nekuchinjika uye mutengo-unobudirira wesoftware-inotsanangurwa yekuchengetedza masisitimu yakavakirwa pane yakajairwa server hardware.

mhedziso
Madhiraivha ane TurboBoost tekinoroji anovhura mikana mitsva yevashandisi uye vanogadzira system yekuchengetedza. Kushandisa yemunharaunda SSD cache inowedzera zvakanyanya mashandiro ehurongwa nekuwedzera kushoma kwemutengo wekutenga madhiraivha.
Miedzo yeSeagate madhiraivha akaitwa mukati yakaratidza chivimbo chepamusoro chekuita pane yakasanganiswa mitoro pateni (70/30), kutevedzera zvinotarisirwa zvinodiwa zvemabasa akaiswa muchikamu chekambani. Panguva imwecheteyo, kuita kwakawanikwa 150 nguva dzakakwirira kupfuura muganhu wemadhiraivha eHDD madhiraivha. Zvakakosha kucherechedza pano kuti mutengo wekutenga masisitimu ekuchengetera iyi dhizaini inenge makumi matanhatu muzana yemutengo weiyo inofananidzwa Yese-Flash mhinduro.
Zviratidzo zvikuru
- Yegore disk kutadza mwero iri pasi pe0.44%
- 40% yakachipa pane All-Flash mhinduro
- 150 nguva nekukurumidza kupfuura HDD
