ʻOiai nā wili a me ka huli ʻana o ka quarantine, ke hoʻomau nei nā kikowaena data. Eia kekahi, me ka ukana ʻoi aku ka nui ma mua, no ka mea, ua hoʻonui nui ʻia ka nui o nā kaʻa pūnaewele. Ua ʻike hou ʻo Backblaze i ka hana ʻoi aku ka maikaʻi. Ua hoʻokuʻu ʻia kahi lawelawe mālama data kapuaʻi kaulana i kahi hōʻike e pili ana i ka hilinaʻi HDD no ka hapaha mua o 2020.
Ke piʻi mau nei ka helu o nā HDD o Backblaze. I ka manawa o ka hōʻike, ua loaʻa i ka hui nā disks 132 i kona hoʻoiho. ʻO kēia mau mea, ʻo 339 ka bootable, 2 nā disks mālama data. Hōʻike ka hōʻike i nā helu no nā hemahema disk mai nā hui like ʻole a me nā mana like ʻole.
No laila, Q2020 XNUMX
I ka pau ʻana o ka manawa hōʻike, ʻo ka helu o nā paʻa paʻa helu helu he 129. ʻO kēia nā HDD kahi i mālama ʻia ai ka ʻikepili o nā mea kūʻai aku. ʻO nā ʻikepili ma nā disks e hoʻāʻo ʻia nei, a me nā hiʻohiʻona ʻaʻole i ʻoi aku ka nui o nā kope 959, ua wehe ʻia mai ka helu. Ma hope o ia kānana, 60 koe. ʻO ka helu o nā lā i hoʻohana ʻia e nā diski he 129 miliona. ʻO ka helu o nā hemahema he 764.
Nā ʻōlelo a ka hui
ʻO 1,07% ka nui o ka hemahema o ka makahiki (AFR). ʻO kēia ka hōʻailona liʻiliʻi no ka manawa holoʻokoʻa o ka nānā ʻana i ka hana o nā paʻakikī, ʻo ia hoʻi, mai 2013. No ka hoʻohālikelike, i ka hapaha mua o 2019, ʻo ka AFR he 1,56%.
I ka hapaha hōʻike, ʻaʻole i hāʻule nā hiʻohiʻona 4 HDD mai ʻekolu mau mea hana. Ua hōʻike ʻia nā diski i ka helu ʻole o ka hemahema Toshiba 4 TB kaha a Seagate kaha o 16 TB. Akā ʻaʻole liʻiliʻi kēia mau hiʻohiʻona - ma kahi o 10 mau lā i ka huina no ka hapaha holoʻokoʻa. No laila, inā hāʻule hoʻokahi kaʻa 000 TB Seagate, ʻo 16% ka AFR no ka hapaha. Ma lalo o nā kūlana like, ʻo ka AFR o Toshiba 7,25 TB drive he 4%.
ʻO ka mea'ē aʻe, nā hiʻohiʻona HGST He nui nā lā i hana ʻia, no laila ʻaʻole like ka AFR ma aneʻi. Inā i hāʻule ke kumu hoʻohālike 8 TB, inā he 0,4% wale nō ka AFR; inā i hāʻule ke kumu hoʻohālike 12 TB, ua piʻi ka AFR i 0,26% no ka hapaha. He mea kupanaha ka helu ʻole o ka hemahema ma ka hihia mua a me ka lua.
Ke ʻano no ka helu ʻana i ka helu hāʻule makahiki
Ma waho o ka manawa nānā (mahina, hapaha, a me nā mea ʻē aʻe), helu hou ʻo Backblaze i nā hemahema āpau i hoʻokahi makahiki. E like me kēia ʻano hoʻohālike:
AFR = (Hōʻole diski / (Ka manawa holo / 366) * 100
ʻAuhea:
- Nā hemahema o ka disk - ka helu o nā HDD i hāʻule i ka wā nānā.
- Nā hola hana - ka helu o nā lā i mau ai ka nānā ʻana i ka hana disk.
- 366 - ka huina o nā lā i loko o ka makahiki (i nā makahiki lele ʻole ke emi nei ka helu i 365).
ʻO nā manaʻolana a me ka ʻoiaʻiʻo ke hoʻohālikelike ʻia me ka hapaha mua o 2019
I hoʻokahi makahiki i hala aku nei, ua hana nā ʻelele ʻoihana i nā wānana e pili ana i ka mea e hiki mai ana ma ka hopena o 2019 (e pili ana i ka hana HDD, ʻoiaʻiʻo). ʻO ka manawa kēia e loiloi i ko lākou pono.
Mākawā: E hoʻomau ka Backblaze i ka hoʻemi ʻana i ka helu o nā drive 4TB i hoʻohana ʻia, no laila e emi iho ma mua o 15 ma ka hopena o 000.
ʻOiaʻiʻo: Aia ma mua o 35 disks no ka mea ʻaʻole lawa ka manawa o ka hui e pani ai iā lākou.
Ka wānana: E hoʻokomo ʻo Backblaze i ka liʻiliʻi o 20 20TB drive no ka hoʻāʻo.
ʻOiaʻiʻo: ʻAʻole i hoʻokō ʻia ka wānana; ʻaʻole i lawe ka hui i hoʻokahi disc e hoʻāʻo ai.
Ka wānana: ʻoi aku ka nui o ka nui o ka waihona ma ka Backblaze DC ma mua o kahi exabyte.
ʻOiaʻiʻo: A pēlā nō, i ka mahina o Malaki ua hala ka hōʻailona exabyte.
Ka wānana: E hoʻouka a hoʻāʻo ʻo Backblaze i hoʻokahi kaʻa HAMR mai Seagate a/a i ʻole 1 kaʻa MAMR mai Western Digital.
ʻOiaʻiʻo: aohe mea i loaa mai; hiki paha kēia i ka hopena o 2020.
E hoʻopiha i nā ʻikepili ma nā pahu paʻakikī mai ka makahiki 2013
Aia ma ka papa ma lalo ka ʻikepili no nā hemahema disk i hoʻokele ʻia e ka hui mai ʻApelila 20, 2013 a i Malaki 31, 2020.
Hoʻonohonoho ʻikepili piha .
Inā makemake ʻoe i nā papa mai kēia ʻatikala, hiki iā ʻoe me ka ʻikepili.
