Chidule cha Chingwe cha SAS Kuchokera ku Internal Interconnection 8087 kupita ku External High-Speed 8654
Pomanga kapena kukonza makina osungira zinthu amakampani, malo ogwirira ntchito ogwira ntchito kwambiri, kapena zida zina za NAS, nthawi zambiri timakumana ndi zingwe zosiyanasiyana zomwe zimafanana. Pakati pawo, zingwe zokhudzana ndi "MINI SAS" ndizofunikira koma zimatha kusokoneza. Lero, tifufuza "Chingwe cha MINI SAS 8087 mpaka 8654 4i"ndi"Chingwe cha MINI SAS 8087"Kuti akuthandizeni kumvetsetsa bwino momwe amagwiritsidwira ntchito komanso kusiyana kwawo."
I. Kumvetsetsa Koyamba: Kodi MINI SAS ndi chiyani?
Choyamba, SAS (Serial Attached SCSI) ndi njira yolumikizira ndi kulamulira zipangizo zakunja za kompyuta, makamaka ma hard disk drive. Yalowa m'malo mwa ukadaulo wakale wa SCSI. MINI SAS ndi mawonekedwe enieni a mawonekedwe a SAS, omwe ndi ochepa kuposa mawonekedwe akale a SAS ndipo amatha kupereka maulumikizidwe apamwamba m'malo ochepa.
Pa nthawi ya kusintha kwa MINI SAS, mitundu yosiyanasiyana ya mawonekedwe yawonekera, pakati pawo SFF-8087 ndi SFF-8654 ndi oimira awiri ofunikira kwambiri.
MINI SAS 8087 (SFF-8087): Iyi ndi njira yakale yolumikizira yamkati ya MINI SAS. Ndi mawonekedwe a 36-pin, omwe nthawi zambiri amagwiritsidwa ntchito kulumikiza bolodi la amayi (khadi la HBA) ku backplane kapena mwachindunji ku ma hard drive angapo. Chingwe chimodzi cha SFF-8087 chimaphatikiza njira zinayi za SAS, chilichonse chili ndi bandwidth yoyerekeza ya 6Gbps (kutengera mtundu wa SAS, chingakhalenso 3Gbps kapena 12Gbps), motero bandwidth yonse imatha kufika 24Gbps.
MINI SAS 8654 (SFF-8654): Iyi ndi njira yatsopano yolumikizira yakunja, yomwe nthawi zambiri imatchedwa Mini SAS HD. Ilinso ndi ma pin 36 koma ndi yaying'ono kwambiri komanso yopapatiza kwambiri. Imagwiritsidwa ntchito makamaka kulumikiza madoko akunja a zida, monga kuchokera ku seva host kupita ku kabati yakunja ya disk. Chida chimodzi cha SFF-8654 chimathandizanso njira zinayi za SAS ndipo chimagwirizana ndi SAS 3.0 (12Gbps) ndi mitundu yapamwamba.
II. Kusanthula kwa Pakati: Chingwe cha MINI SAS 8087 mpaka 8654 4i
Tsopano, tiyeni tiyang'ane pa mawu oyamba ofunikira:Chingwe cha MINI SAS 8087 mpaka 8654 4i.
Kuchokera pa dzinalo, tikhoza kutanthauzira mwachindunji:
Mbali imodzi ndi mawonekedwe a SFF-8087 (mawonekedwe amkati)
Mbali ina ndi mawonekedwe a SFF-8654 (mawonekedwe akunja)
"4i" nthawi zambiri imayimira "njira 4 mkati", apa zitha kumveka chifukwa chingwechi chili ndi kulumikizana kwathunthu kwa njira 4 za SAS.
Kodi ntchito yaikulu ya chingwe ichi ndi yotani? - Ndi "mlatho" wolumikiza malo osungiramo zinthu mkati ndi kunja kwa seva.
Zochitika zodziwika bwino zogwiritsira ntchito:
Tangoganizirani kuti muli ndi seva ya nsanja kapena malo ogwirira ntchito okhala ndi khadi la HBA pa bolodi la amayi lomwe lili ndi mawonekedwe a SFF-8087. Tsopano, muyenera kulumikiza kabati yakunja ya SAS disk array, ndipo mawonekedwe akunja a kabati iyi ya disk array ndi SFF-8654 yeniyeni.
Panthawiyi,Chingwe cha MINI SAS 8087 mpaka 8654 4iimayamba kugwira ntchito. Mumayika mapeto a SFF-8087 mu khadi lamkati la HBA la seva, ndikulumikiza mapeto a SFF-8654 ku doko la kabati yakunja ya disk. Mwanjira imeneyi, seva imatha kuzindikira ndikuwongolera ma hard drive onse omwe ali mu kabati ya disk.
Mwachidule, iyi ndi njira yolumikizirana "kuchokera mkati kupita kunja", yomwe imatumiza deta mwachangu komanso mopanda phokoso kuchokera ku chowongolera cha SAS mkati mwa seva kupita ku chipangizo chosungira chakunja.
III. Kumvetsetsana Koyerekeza:Chingwe cha MINI SAS 8087
Mawu achiwiri ofunikira akuti "MINI SAS 8087 Cable" ndi lingaliro lalikulu, ponena za chingwe chokhala ndi mbali imodzi kapena zonse ziwiri kukhala ma interface a SFF-8087. Nthawi zambiri chimagwiritsidwa ntchito polumikizira zipangizo mkati.
Mitundu yodziwika bwino ya MINI SAS 8087 Cable ndi iyi:
Mtundu wolumikizira mwachindunji (SFF-8087 kupita ku SFF-8087): Mtundu wofala kwambiri, womwe umagwiritsidwa ntchito polumikizira mwachindunji pakati pa khadi la HBA ndi backplane ya seva.
Mtundu wa nthambi (SFF-8087 mpaka 4x SATA/SAS): Mbali imodzi ndi SFF-8087, ndipo mbali inayo imafalikira m'magawo anayi odziyimira pawokha a SATA kapena SAS. Chingwechi nthawi zambiri chimagwiritsidwa ntchito kulumikiza khadi la HBA mwachindunji ku ma hard drive anayi odziyimira pawokha a SATA kapena SAS popanda kudutsa kumbuyo.
Mtundu wa nthambi yosinthira (SFF-8087 kupita ku SFF-8643): Imagwiritsidwa ntchito polumikiza makadi akale a HBA okhala ndi mawonekedwe atsopano (monga SFF-8643) ku backplane kapena hard drive.
Kusiyana kwakukulu pakati pa chingwe cha 8087 ndi 8654:
Gawo logwiritsira ntchito: Chingwe cha MINI SAS 8087 chimagwiritsidwa ntchito makamaka mu chassis ya seva; pomwe Chingwe cha 8087 mpaka 8654 chimagwiritsidwa ntchito makamaka polumikiza zida zamkati ndi zakunja.
Malo ogwirira ntchito: Choyamba ndi chingwe cha "internal interconnection", pomwe chachiwiri ndi chingwe cha "internal-exterior bridge".
IV. Chidule ndi Malangizo Ogulira
Chingwe cha MINI SAS 8087 mpaka 8654 4i Chingwe cha General MINI SAS 8087
Kuphatikiza kwa ma connection Malekezero amodzi SFF-8087, malekezero amodzi SFF-8654 Nthawi zambiri malekezero onse awiri amakhala SFF-8087, kapena malekezero amodzi amakhala nthambi
Ntchito yaikulu Kulumikiza makabati okulitsa malo osungira mkati ndi kunja kwa seva Kulumikizana kwa gawo mkati mwa ma seva ndi zida zosungira
Zochitika za ntchito Kulumikizana kwa DAS Yakunja (Kusungirako Kolumikizidwa Mwachindunji) Kulumikiza khadi la HBA ku backplane, kapena kulumikiza mwachindunji ma hard drive
Mtundu wa chingwe Chingwe chakunja (nthawi zambiri chimakhala chokhuthala, choteteza bwino) Chingwe chamkati
Malangizo Ogulira: Fotokozani zofunikira: Kodi muyenera kulumikiza zipangizo zakunja kapena kungogwiritsa ntchito mawaya amkati?
Tsimikizirani ma interfaces: Musanagule, chonde yang'anani mosamala mitundu ya ma interfaces pa seva yanu ya HBA card ndi kabati yowonjezera. Dziwani ngati ndi SFF-8087 kapena SFF-8654.
Samalani mitundu: Onetsetsani kuti zingwe zikuthandizira liwiro la SAS lomwe mukufuna (monga SAS 3.0 12Gbps). Zingwe zapamwamba kwambiri zitha kutsimikizira kukhazikika kwa chizindikiro ndi kukhazikika.
Kutalika koyenera: Sankhani kutalika koyenera kwa zingwe kutengera kapangidwe ka kabati kuti mupewe kukhala zazifupi kwambiri kuti zilumikizidwe kapena zazitali kwambiri kuti zisokoneze.
Kudzera mu kusanthula komwe kwatchulidwa pamwambapa, tikukhulupirira kuti mukumvetsa bwino za "MINI SAS 8087 mpaka 8654 4i Cable" ndi "MINI SAS 8087 Cable". Ndi "zombo" zofunika kwambiri popanga njira yosungiramo zinthu yogwira ntchito komanso yodalirika. Kusankha bwino ndikugwiritsa ntchito bwino ndiko maziko otsimikizira kuti dongosololi likugwira ntchito bwino.
