ʻElua mau mahina i hala aku nei, ua loaʻa iā Radix ka manawa e hana pū me nā mea hoʻokele Seagate EXOS hou loa, i hoʻolālā ʻia no nā hana ʻoihana. ʻO kā lākou hiʻohiʻona ʻokoʻa, ʻo ia ka mea hoʻokele hybrid - hoʻohui ia i nā ʻenehana o nā hard drive maʻamau (no ka mālama nui) a me nā drive solid-state (no ka mālama ʻana i ka ʻikepili wela).
Ua loaʻa iā mākou kahi ʻike maikaʻi e hoʻohana ana i nā drive hybrid mai Seagate ma ke ʻano he ʻāpana o kā mākou ʻōnaehana - he mau makahiki i hala aku nei ua hoʻokō mākou i kahi hopena no kahi kikowaena data pilikino me kahi hoa mai South Korea. A laila ua hoʻohana ʻia ka benchmark Oracle Orion i nā hoʻokolohua, a ʻo nā hopena i loaʻa ʻaʻole i haʻahaʻa i ka All-Flash arrays.
Ma kēia ʻatikala e nānā mākou i ka hoʻolālā ʻana o Seagate EXOS me ka ʻenehana TurboBoost, loiloi i ko lākou hiki no nā hana ma ka ʻāpana hui, a hoʻāʻo i ka hana ma lalo o nā haʻahaʻa hui ʻia.
Nā hana o ka ʻāpana ʻoihana
Loaʻa ka nui a i ʻole ka liʻiliʻi paʻa o nā hana i hiki ke koho ʻia e like me nā hana mālama ʻikepili ma ka ʻāpana hui (a i ʻole ʻoihana). ʻO kēia mau mea maʻamau: ka hana ʻana o nā noi CRM a me nā ʻōnaehana ERP, ka hana ʻana o nā leka uila a me nā faila, nā hana hoʻihoʻi a me ka virtualization. Mai kahi manaʻo o ka ʻōnaehana mālama, ʻike ʻia ka hoʻokō ʻana o ia mau hana e kahi kahe haʻahaʻa hui ʻia, me ka predominance maopopo o nā noi random.
Eia kekahi, ke ulu ikaika nei nā wahi waiwai e like me ka multidimensional analytics OLAP (Online Analytical Processing) a me ka hoʻoili ʻana i ka manawa maoli (OLTP, Online Transaction Processing) i ka māhele ʻoihana. ʻO kā lākou hiʻohiʻona ʻoi aku ka hilinaʻi ʻana i nā hana heluhelu ma mua o nā hana kākau. ʻO ka haʻahaʻa hana a lākou e hana ai—nā kahawai ʻikepili koʻikoʻi me ka nui o nā poloka liʻiliʻi—pono ka hana kiʻekiʻe mai ka ʻōnaehana.
Ke piʻi wikiwiki nei ke kuleana o kēia mau hana āpau. Hoʻopau lākou i nā poloka kōkua i nā kaʻina hana waiwai a neʻe i ka ʻāpana o nā mea nui o ka huahana. No nā ʻano ʻoihana he nui, lilo kēia i mea koʻikoʻi o ke kūkulu ʻana i ka pono hoʻokūkū a me ka hoʻomau ʻana o ka mākeke. I ka huli ʻana, hoʻonui nui kēia i nā koi no nā ʻoihana IT ʻoihana: pono nā lako ʻenehana e hāʻawi i ka throughput kiʻekiʻe a me ka manawa pane liʻiliʻi. No ka hōʻoia ʻana i ka hana i koi ʻia ma ia mau kūlana, koho i nā ʻōnaehana All-Flash a i ʻole nā ʻōnaehana mālama hybrid me a luhi paha.
Eia kekahi, aia kekahi ʻano kumu ʻē aʻe o ka māhele ʻoihana - nā koi koʻikoʻi no ka hoʻokele waiwai. He mea maopopo loa ʻaʻole hiki i nā hale ʻoihana āpau ke kūʻai aku a mālama ʻia i nā arrays All-Flash, no laila nui nā ʻoihana e haʻalele iki i ka hana, akā kūʻai aku i nā ʻoi aku ka maikaʻi o ka uku. Ke hoʻololi nei kēia mau kūlana i ka nānā ʻana o ka mākeke i nā hoʻonā hybrid.
ʻO ke kumu Hybrid a i ʻole ʻenehana TurboBoost
ʻO ke kumu o ka hoʻohana ʻana i nā ʻenehana hybrid i kēia manawa i ʻike ʻia e ka lehulehu ākea. 'Ōleloʻo ia e pili ana i ka hiki ke hoʻohana i nāʻenehana likeʻole e loaʻa ai nā pono hou i ka hopena hope loa. Hoʻohui nā ʻōnaehana mālama hybrid i nā ikaika o nā mea hoʻokele paʻa a me nā pahu paʻakikī maʻamau. ʻO ka hopena, loaʻa iā mākou kahi hopena maikaʻi loa, kahi e hana ai kēlā me kēia ʻāpana me kāna hana ponoʻī: Hoʻohana ʻia ʻo HDD e mālama i ka nui o ka ʻikepili, a hoʻohana ʻia ʻo SSD e mālama i ka "ʻikepili wela".
Wahi a , ma ka ʻāina EMEA ma kahi o 45.3% o ka mākeke i hana ʻia i nā ʻōnaehana mālama hybrid. Hoʻoholo ʻia kēia kaulana e ka ʻoiaʻiʻo, ʻoiai ka hana hoʻohālikelike, ʻoi aku ka haʻahaʻa o ke kumukūʻai o ia mau ʻōnaehana ma mua o nā hoʻonā SSD-based, a ʻo ke kumu kūʻai no kēlā me kēia IOps e waiho ana ma hope o nā kauoha o ka nui.
Hiki ke hoʻokō pololei ʻia ke kumu hybrid like ma ka pae hoʻokele. ʻO Seagate ka mea mua i hoʻokō i kēia manaʻo ma ke ʻano o ka media SSHD (Solid State Hybrid Drive). Ua loaʻa kēia mau disc i ka kaulana kaulana i ka mākeke mea kūʻai aku, akā ʻaʻole maʻamau i ka māhele b2b.
ʻO ka hanauna hou o kēia ʻenehana ma Seagate e hele ana ma lalo o ka inoa kalepa TurboBoost. No ka ʻāpana hui, hoʻohana ka ʻoihana i ka ʻenehana TurboBoost i ka laina o nā drive Seagate EXOS, kahi i hoʻonui i ka hilinaʻi a me kahi hui maikaʻi o ka hana a me ka pono. ʻO kahi ʻōnaehana mālama i hōʻuluʻulu ʻia ma ke kumu o ia mau disks, e pili ana i kāna mau hiʻohiʻona hope, e pili ana i kahi hoʻonohonoho hybrid, ʻoiai ka caching o ka ʻikepili "wela" e loaʻa ana ma ka pae kaʻa a hana ʻia me ka hoʻohana ʻana i nā mana firmware.
Hoʻohana ʻo Seagate EXOS drive i ka 16 GB o ka eMLC (Enterpise Multi-Level Cell) i hoʻomanaʻo ʻia NAND no ka cache SSD kūloko, nona ka waiwai kākau hou ʻoi aku ka kiʻekiʻe ma mua o ka MLC mea kūʻai.
Mea hoohana like
Ma hope o ka loaʻa ʻana o 8 Seagate EXOS 10E24000 1.2 TB drive ma kā mākou makemake, ua hoʻoholo mākou e hoʻāʻo i kā lākou hana ma ke ʻano he ʻāpana o kā mākou ʻōnaehana ma muli o RAIDIX 4.7.
Ma waho, ua like ke kaʻa me kahi HDD maʻamau: kahi pahu metala 2,5-inch me kahi hōʻailona hōʻailona a me nā puka maʻamau no nā mea hoʻopaʻa.
Hoʻolako ʻia ka drive me kahi interface 3 Gb/s SAS12, e ʻae iā ia e hana maikaʻi me ʻelua mau ʻōnaehana mālama. He mea kūpono hoʻi e ʻike ʻia he ʻoi aku ka hohonu o kēia interface ma mua o SATA3.
E hoʻomanaʻo mai kahi manaʻo hoʻokele, ʻike ʻia kahi disk i loko o kahi ʻōnaehana mālama ʻana he ʻano hoʻokahi kahi i hoʻokaʻawale ʻole ʻia ai ka wahi mālama i nā wahi HDD a me SSD. Hoʻopau kēia i ka pono no kahi cache SSD polokalamu a hoʻomaʻamaʻa i ka hoʻonohonoho ʻōnaehana.
Ma ke ʻano he hiʻohiʻona noi no kahi hoʻonā i hana ʻia, ua noʻonoʻo ʻia ka hana me ka ukana mai nā noi hui maʻamau.
ʻO ka pōmaikaʻi nui i manaʻo ʻia mai ka ʻōnaehana mālama i hana ʻia ʻo ia ka maikaʻi o ka hana ʻana i nā ukana hui pū me ka nui o nā hana heluhelu. Hāʻawi nā ʻōnaehana hoʻopaʻa polokalamu RAIDIX i ka hana kiʻekiʻe no nā haʻahaʻa hana, ʻoiai ʻo Seagate e hoʻokele me ka ʻenehana TurboBoost e kōkua i ka hoʻokō ʻana i ka hana no nā haʻawina hana maʻamau.
No ka hiʻohiʻona i koho ʻia, e like me kēia: e hōʻoia ʻia ka maikaʻi o ka hana ʻana me nā ukana maʻamau mai nā waihona a me nā hana noiʻi ʻē aʻe e nā mea SSD, a ʻo nā kikoʻī o ka polokalamu e ʻae i ka mālama ʻana i ka wikiwiki o ka hoʻoili ʻana i nā ukana sequential mai ka hoʻihoʻi ʻikepili a i ʻole. hoʻouka ʻikepili.
I ka manawa like, ʻike maikaʻi ka ʻōnaehana holoʻokoʻa ma ke ʻano o ke kumukūʻai a me ka hana: ʻoi aku ka maikaʻi (e pili ana i ka All-Flash) hybrid drive me ka maʻalahi a me ka maikaʻi o nā ʻōnaehana hoʻopaʻa ʻana i ka polokalamu i kūkulu ʻia ma luna o nā lako kikowaena maʻamau.
Ka ho'āʻo hana
Ua ho'āʻo ʻia me ka hoʻohana ʻana i ka pono fio v3.1.
He kaʻina o nā hoʻāʻo fio minuke lōʻihi o 32 mau lola me ka hohonu o ka laina o 1.
Hoʻohui ʻia ka hana: 70% heluhelu a me 30% kākau.
Ka nui poloka mai 4k a i 1MB.

ʻO kahi ʻōnaehana i hoʻokumu ʻia ma RAIDIX 4.7 me 8 Seagate EXOS 10e2400 drive e hōʻike ana i ka hana holoʻokoʻa a hiki i 220 IOps no ka heluhelu / kākau ʻana me kahi poloka 000k.

ʻO nā hoʻokele me ka ʻenehana TurboBoost e wehe i nā mea hou no nā mea hoʻohana a me nā mea hana ʻōnaehana mālama. ʻO ka hoʻohana ʻana i kahi cache SSD kūloko e hoʻonui nui i ka hana ʻōnaehana me ka piʻi iki o ke kumukūʻai o ke kūʻai ʻana i nā drive.
Hana ʻia nā hoʻāʻo ʻana o nā kaʻa Seagate ma hōʻike i kahi kūlana kiʻekiʻe kiʻekiʻe o ka hana ma kahi ʻano haʻawe huikau (70/30), e hoʻohālikelike ana i nā koi pili o nā hana i noi ʻia ma ka ʻāpana hui. I ka manawa like, ua hoʻokō ʻia ka hana he 150 mau manawa kiʻekiʻe ma mua o nā palena palena o nā drive HDD.
