I-Seagate SkyHawk AI - inkulu futhi iyaphindisela

Ekupheleni konyaka odlule, ububanzi bemishini yethu bugcwaliswe ngomugqa omusha, I-SkyHawk AI. Lawa madrayivu aklanyelwe ukusebenza ezinhlelweni zokugada amavidiyo asekelwa ubuhlakani bokwenziwa. Namuhla sifuna ukukutshela ngokuningiliziwe mayelana ne-flagship yayo - imodeli I-Seagate ST16000VE000 c 16 TB yenkumbulo. I-HDD eyodwa kuphela enjalo ekhethekile ingagcina inyanga yokurekhodwa evela kumakhamera agadayo ayi-15, iqopha ividiyo ngesinqumo esigcwele se-HD kumafreyimu angama-25 ngomzuzwana ubusuku bonke.

Eminyakeni eyishumi nje edlule, umjikelezo wamakhamera agadayo ayi-15 wawuyizinga lebhizinisi elikhulu lezimboni noma indawo evikelekile yenkantolo, uhulumeni noma esinye isikhungo esibaluleke ngokukhethekile. Namuhla, amakhamera angu-15 angase abe ngawebhizinisi elincane elilawula indawo yokugcina izimpahla nehhovisi, isikhungo sokufaneleka noma isitolo esincane. Okusho ukuthi, akuseyona into ewubukhazikhazi, kodwa indlela yokuqopha ividiyo, ingxenye ewusizo yokuphepha ngokomzimba. Kodwa azikho izinkinga ezimbalwa: amagigabhayithi evidiyo yekhwalithi enhle adinga ukurekhodwa futhi agcinwe endaweni ethile, futhi lokhu futhi kuyisici esiyinhloko sokuphepha - kungenjalo kungani wonke lawa makhamera?

Ekubukeni kwama-hard drive, kunzima ukuqhamuka nento entsha ngokuyisisekelo. Ifomu ledivayisi ngu-3.5”, umzimba wenziwe nge-aluminium, isembozo esiphezulu siyisicaba, nesitikha esikhulu sokumaka:

Ngezansi kukhona indawo emnyama engekho ngaphansi kwesicaba, ingxenye yesine yayo ehlala ibhodi langaphandle ledivayisi. Kukhona nezimbobo ezi-4 ezifakwayo.

Kukhona umthungo oshiselwe ezungeze umjikelezo wonke, oqinisekisa ukuqina okuphelele kokugcwalisa - ngeke kusebenze ukungena ngaphakathi ekhaya. Futhi asikho isidingo, ngaphandle kokuthi mhlawumbe ngenxa yelukuluku, isithukuthezi noma ukuthola izikhumbuzo ezibizayo (nakuba ngokubukeka kukhona "ama-pancake" afanayo nakwamanye ama-disc).

Kunezimbobo eziyisikulufa ezintathu ohlangothini ngalunye - idrayivu ingafakwa kunoma yimuphi ubhasikidi, ngisho nakumfushane.

Ngesicelo sabasebenzi (kusuka ukuphawula ekubuyekezweni kwangaphambilini) sinikeza izilinganiso ezinembe kakhulu:

Ngaphambili kunesitika sokumaka esinenombolo ye-serial yedrayivu - ukuze ukwazi ukuthola kalula idrayivu oyifunayo kusitaki se-NAS.

Sebenzisa

Uma unekhamera eyodwa kuphela elenga endaweni ethile emhubheni ekhaya, khona-ke ngisho nakulokhu kuzodingeka ugcine ividiyo erekhodiwe endaweni ethile (asicabangi ngezinsizakalo zamafu kuleli cala - isitoreji sevidiyo sikhona kunembeza wabanikazi) .

Ukuze siqonde isikali, ake siphendukele kuthebula, elibonisa usayizi olinganiselwe wehora elingu-1 lokuqoshwa kwevidiyo nge-bitrate engaguquki (ngokuqhathanisa kabi kakhulu):

Kuvela ukuthi esimweni sekhamera eshiwo, cishe noma iyiphi idrayivu ifanelekile, ngisho ne-500 GB - kuyoba nesikhala esanele cishe isonto lonke lokurekhoda okuqhubekayo ngekhwalithi enhle (futhi uma ubhala ku-motion sensor, khona-ke eside). Futhi uma usebenzisa ngisho ne-SkyHawk drive elula (8 TB), izovala isidingo sokugcinwa kwevidiyo izinyanga noma iminyaka.

Kodwa-ke, lapho sithuthukisa ama-disc ochungechunge lwe-SkyHawk, besicabanga ukubhekwa kwevidiyo okuhluke kancane, ngezinga elikhulu. Iminyango, izitolo, izimboni, izimboni, izikhungo zikahulumeni - zonke lezi (kanye nezinye eziningi) izimo ezisebenzisa inqwaba noma amakhulu amakhamera anencazelo ephezulu, anezilungiselelo nobuchwepheshe obuhlukahlukene. Ukuze ividiyo evela kubo iqhubeke idlule kumadivayisi angochwepheshe, aqoshwe kuma-multi-disk array futhi agcinwe ngokuthembekile isikhathi eside. Konke lokhu kuyisici somdabu se-SkyHawk.

Lapha, esikhundleni setafula elingabonakali, kungcono ukulisebenzisa umshini wokubala wethu, enezilungiselelo zokokufaka ezengeziwe kanye nokuphumayo okunembe kakhudlwana. Vele ucacise imingcele oyifunayo (inani lamakhamera / ikhwalithi yokurekhoda kusuka kuwo / inombolo yamahora okurekhoda ngosuku nezinsuku zokugcina / i-codec) futhi uthole inani ledatha ehlalayo:

Ngakho-ke, ukuhambisa izilayidi, sithola ukuthi iqhawe lokubuyekezwa kwanamuhla (i-SkyHawk AI 16 TB) yanele ukugcina ividiyo kusuka kumakhamera we-15 inyanga, ezoqopha ubusuku nemini ngekhwalithi ye-FullHD ngemvamisa yamafreyimu angama-25 ngomzuzwana. (cabanga nge-cinema).

// (!)(!)(!) — Izibabazo zokuzibeka emshweni odlule.

Amakhamera ayi-15, ngokwesibonelo, ayisakhiwo sokuhlala, esinamakhamera ama-7 alenga emnyango ngamunye kweziyi-2 - indawo evikelekile ngokuphelele enekhono lokucwila endaweni egcina umlando wevidiyo inyanga yonke. I-SkyHawk AI yakhelwe ukusebenza ubusuku nemini ezinhlelweni zokugada amavidiyo, ezinomthwalo ofika ku-550 TB ngonyaka - lokhu kucishe kuphindwe kathathu kunemishini yokugada amavidiyo ajwayelekile. Futhi uma unesidingo somthwalo ophakeme wokusebenza, sincoma ukusebenzisa amadrayivu ebanga lebhizinisi le-Seagate (isibonelo, i-Exos, ukubuyekeza ebikubhulogi yethu).

Vele, wonke lawa makhamera ngeke axhumeke ngqo ku-hard drive, kodwa ngedivayisi ebiza kakhulu ye-NVR / XVR / *** ezokwenza wonke umsebenzi: hlela ingobo yomlando futhi uyifinyelele, ikhophi yasenqolobaneni, yenza ividiyo. imifudlana (ukutholwa kwabantu, izimoto , ukubona ubuso, ...), njll. Akuwona wonke amadivaysi, ngisho avela ezinkampanini ezidumile, anokusekelwa kokushayela kwevolumu enkulu kangaka, kodwa kukhona kakade okuningi ongakhetha kukho: kusukela kumholi womhlaba u-Hikvision (ngokwesibonelo, ku-I-series, i-Super NVR kanye nemigqa ye-DeepInMind NVR) kwabangaziwa kakhulu - i-Dahua, i-TVT noma i-Uniview. Kungafakwa amadrayivu e-SkyHawk afinyelela kwangu-16 kumadivayisi e-HikVision - cabanga nje lokhu kusetha kanye namathuba ako.

Masibuyele kudiski yethu. Isivinini sokuphotha singu-7200 rpm - incazelo yegolide, ehlinzeka idivayisi ngokusebenza okudingekayo ekusebenzeni ngevidiyo. Kanye nokuqina kanye nezinga eliphansi lomsindo. Ungabona amanani omsindo epuletini, kepha amanani anikezwe lapho kudiski "etafuleni" - empeleni, idiski izofihlwa ku-NAS / NVR noma ku- izibilini zeyunithi yesistimu, lapho kungeke kube khona umsindo nokudlidliza okuvela kuyo.

Izilinganiso zesivinini zenziwe ngohlobo olusungulwe kahle lwe-HD Tune Pro 5.70. Zonke izithombe-skrini ziyachofozeka.

Ukufundwa komugqa - kusuka ku-120 kuya ku-266 MB / s ngenani eliphakathi kuka-209 MB / s, amanani afanayo okubhala. Isikhathi sokufinyelela okungahleliwe sisebangeni lika-11.6 - 13 ms lokufunda kanye neshumi lama-millisecond okubhala - umphumela omuhle, ikakhulukazi ngenxa yenqolobane ehlukile.

Wonke amadrayivu ochungechunge lwe-Seagate SkyHawk AI ane-256 MB yenqolobane, usayizi oqinile, kodwa kulokhu idlala indima ekhethekile. I-firmware yediski iqukethe inguqulo entsha ye-algorithm Isithombe Esiphelele I-AI, okuthuthukisa ukusakazwa kwevidiyo, iqinisekisa ukuthi awekho amafreyimu awehlisiwe ekurekhodweni, futhi inciphisa amaphutha edatha. I-algorithm isuselwe kubuchwepheshe bokulondoloza isikhashana obunamazinga amaningi (MTC, Multi-Tier Caching) futhi inikeza:

• Ukusakazwa kwevidiyo okungu-64/XNUMX kusuka kumakhamera we-HD angama-XNUMX.
• Ukusakaza ngesivinini esiphezulu.
• Abekho ozimele abehlisiwe (ngenxa yama-algorithms okulungiswa kwamaphutha nokwakhiwa kabusha kwedatha).
• Ubuqotho besithombe esiphezulu.
• Ukusekelwa kwesethi yomyalo wokusakaza we-ATA-8 (yokudlulisa idatha, okubaluleke kakhulu kunikezwa isikhathi kunobuqotho bedatha, kuvumela umsingathi ukuthi acele ukulethwa kwedatha ngesikhathi esithile), elungiselelwe ukucubungula idatha enkulu elandelanayo, ejwayelekile kuvidiyo. amafayela.

  

Ukuze uthole ulwazi olwengeziwe mayelana nokuthi ubuchwepheshe busebenza kanjani, bheka lesi sixhumanisifuthi ubuke le vidiyo:

Bona idokhumenti exhunywe ngenhla ukuze uthole imininingwane eyengeziwe yokuthi ubuchwepheshe be-AcuTrac buletha kanjani ukusebenza okungaguquki nokwethembeka ngisho nasezindaweni zokudlidliza okuphezulu.

Futhi ebhodini kukhona i-SkyHawk Health Management (SHM) - isofthiwe ekhethekile eyenziwe ngokubambisana ne-Hikvision (yezinhlelo ezine-NVR OS 4.0) - I-SMART kuma-steroids, eye yadlula izinga lemboni. Ubuchwepheshe buqapha futhi buhlaziye idatha ngempilo nokusebenza kwediski, okungasiza ekuvimbeleni izinkinga ezingenzeka ngesikhathi.

Imininingwane ye-Seagate SkyHawk AI

Uhlelo lwe-SkyHawk AI luhlanganisa amadivayisi anevolumu engu-8, 10, 12, 14 kanye ne-16 TB. Ngaphezu kwevolumu, zihluka kuphela ngesisindo, inani lamapuleti, ukusetshenziswa kwamandla kanye nezinga eliphansi kakhulu lokudluliswa kwedatha kububanzi obungaphandle (kumamodeli amancane).
