Pofika pa Disembala 31, 2019, tili ndi ma hard drive opitilira 124. Mwa izi, 956 ndi zosinthika ndipo 2 ndi data. Mu ndemanga iyi, tiwona ziwerengero zolephera pakati pa ma hard drive a data. Tikambirananso mitundu 229 ndi 122 ya ma disks ndi 658 TB yatsopano, yomwe takhala tikugwiritsa ntchito kuyambira kotala lachinayi la 12.
Ziwerengero za 2019
Kumapeto kwa 2019, tidawunika ma hard drive 122 omwe amagwiritsidwa ntchito posungira deta. Tidachotsa pamagalimoto owerengera omwe adagwiritsidwa ntchito poyesa ndi ma drive omwe analibe ~ 658 masiku oyendetsa (pamtundu uliwonse) pagawo lachinayi. Chifukwa chake, tidasonkhanitsa deta kutengera 5 hard drive. Tebulo ili pansipa likuwonetsa ziwerengero zathu:
Zolemba ndi zowonera
151 hard drive (122 minus 658) sanaphatikizidwe mu ziwerengero. Ma drive awa adagwiritsidwa ntchito poyesa kapena sanagwire ntchito masiku onse oyendetsa 122 mgawo lachinayi la 507. Chifukwa chake, timachotsa pama disks owerengera omwe, m'malingaliro athu, sanagwire ntchito nthawi yayitali kuti apange lingaliro lililonse.
Galimoto yokhayo yopanda vuto ya 2019 ndi 4 TB Toshiba, chitsanzo: MD04ABA400V. Izi ndi zotsatira zabwino kwambiri, koma popeza tinali ndi zoyendetsa zochepa, ngati galimoto imodzi yokha italephera, tikadalandira pafupifupi 0.92%. Zabwino, koma osatinso 0%.
Toshiba 14 TB model MG07ACA14TA ikuwonetsa zotsatira zabwino kwambiri ndi 0.65% AFR ndipo imayima pafupi ndi ma drive ochokera ku HGST. Seagate 6 TB ndi 10 TB ndizokhazikika pa 0.96% ndi 1.00%, motsatira.
AFR ya 2019 pama drive onse ndi 1.89%, yomwe ili yochulukirapo kuposa ya 2018. Tidzakambirana pambuyo pake.
Kupitilira ziwerengero - mitundu "yobisika" ya disk
Mitundu yambiri sinaphatikizidwe mu ziwerengero zathu za 2019 chifukwa sanagwire ntchito nthawi yokwanira. Tikufuna kukambirana za zitsanzozi ndi momwe timazigwiritsira ntchito.
Seagate 16 TB
Mu kotala yachinayi ya 2019, tidayamba kuyenerera ma drive a Seagate 16 TB, chitsanzo: ST16000NM001G. Kumapeto kwa kotala yachinayi, tinali ndi zoyendetsa 40, zomwe zikuyimira masiku onse a disco 1, pansi pa malire a masiku 440 pa ziwerengero zathu za 5. Panalibe zolephera pakati pa zoyendetsa izi mu gawo lachinayi. Mukamaliza bwino ziyeneretso zathu, zidzagwiritsidwa ntchito ngati zathu chaka chino.
Mtengo wa 8TB
Mu Q4 2019 panali ma drive 20 a Toshiba 8 TB, mtundu: HDWF180. Ma disks amenewa anagwira ntchito kwa zaka ziwiri. Mu gawo lachinayi anali ndi masiku ogwiritsira ntchito 1 okha, omwe ali pansi pa chiwerengero cha ziwerengero, koma ali ndi moyo wa masiku a 840 ndi kulephera kumodzi kokha, kutipatsa AFR ya 13%. Timakonda zoyendetsa izi, koma titakwanitsa kuzigula mumilingo yomwe timafunikira, zidayamba kuwononga ndalama zokwana 994 TB. Mphamvu zambiri, mtengo womwewo. Poganizira kuti tikusamukira ku 2,6TB ndi ma drive okulirapo, mwina sitidzagula ma drive awa mtsogolomu.
HGST 10 TB
Pali ma drive 20 HGST 10 TB omwe akugwira ntchito, mtundu: HUH721010ALE600. Ma disks amenewa akhala akugwiritsidwa ntchito kwa chaka chimodzi chokha. Ali m'malo osungiramo Backblaze monga ma drive a Seagate 10TB. Pamagawo a 4, ma drive a HGST adagwira ntchito kwa masiku 1 okha, ndipo kuyambira kukhazikitsa - 840. Panali zolephera za 8 (zero). Monga ndi Toshiba 042TB, kugula zambiri za mtundu wa 0TB sikutheka.
Mtengo wa 16TB
Simuwapeza pamawerengero a Q2020, koma mu Q20 16 tidawonjezera ma drive 08 a Toshiba 16TB, Model: MG100ACA2020TA. Adagwira ntchito kwa masiku XNUMX, kotero kwatsala pang'ono kuyankhula china chilichonse kupatula ziwerengero za kotala yoyamba ya XNUMX.
Kuyerekeza kwa ma hard drive statistics a 2017, 2018 ndi 2019.
Gome lomwe lili pansipa likufananiza mitengo yapachaka (AFR) pazaka zitatu zapitazi:
Kukula kwa AFR mu 2019
AFR yonse ya 2019 idakwera kwambiri. AFR idakwera 75% yamitundu kuyambira 2018 mpaka 2019. Pali zinthu ziwiri zazikulu zomwe zimayambitsa kukula kumeneku. Choyamba, mzere wonse wa 8 TB umayendetsa "vuto lapakati pa moyo" momwe amagwiritsidwira ntchito. Ma AFR apamwamba kwambiri amawonetsedwa ndi ma drive omwe ali mgulu la 8 TB. Ngakhale AFR yokwera kwambiri, palibe chifukwa chodera nkhawa kwambiri. Chowonadi ndi chakuti ma disks agwira ntchito 1/4 ya masiku a ziwerengero zathu zonse ndipo kusintha pang'ono kungawakhudze. Chinthu chachiwiri ndi ma drive a Seagate 12 TB, vutoli likuthetsedwa mwachangu mkati mwa polojekitiyi , zomwe zinanenedwa kale.
Kusamuka kukuchedwa, koma kukula sikuli
Mu 2019, tidawonjezera ma drive 17 atsopano. Mu 729, ma drive ambiri 2018 omwe adawonjezeredwa adagwiritsidwa ntchito ngati gawo lakusamuka. Mu 14, ochepera theka la ma drive atsopano adapangidwa kuti asamuke, ndipo ena onse amagwiritsidwa ntchito pamakina atsopano. Mu 255, tidasiya ma drive 2019 pa ma petabytes onse 2019 ndikuyikamo ma drive 8, onse 800 TB, omwe ali pafupifupi ma petabytes 37, kenako mu 8 tidawonjezera ma petabytes ena 800 osungira pogwiritsa ntchito ma drive 12 ndi 105 TB.
Zosiyanasiyana
Mitundu yosiyanasiyana ya opanga ndi mtundu wa drive idakwera pang'ono mu 2019. Mu 2018, ma drive a Seagate adapanga 78,15% yama drive, ndipo pofika kumapeto kwa 2019, chiwerengerochi chidatsika mpaka 73,28%. HGST idakwera kuchoka pa 20,77% mu 2018 kufika pa 23,69% mu 2019, ndipo Toshiba kuchoka pa 1,34% mu 2018 kufika pa 3,03% mu 2019. Panalibe ma drive amtundu wa Western Digital mu data center mu 2019. popeza WDC inali kutulutsanso HGST yatsopano.
Ziwerengero za moyo wautumiki
Ngakhale kufananiza mitengo ya hard drive yapachaka pazaka zingapo ndi njira yabwino yodziwira zomwe zikuchitika, timayang'ananso kulephera kwapachaka kwa ma hard drive athu pa moyo wawo wonse. Tchati chomwe chili pansipa chikuwonetsa kulephera kwapachaka kwamitundu yonse yamagalimoto yomwe ikupanga kuyambira pa Disembala 31, 2019:
