Chiwonetsero Chachingwe cha SAS Kuchokera ku Internal Interconnection 8087 kupita ku External High-Speed 8654
Tikamamanga kapena kukweza makina osungira mabizinesi, malo ogwirira ntchito kwambiri, kapena zida zina za NAS, nthawi zambiri timakumana ndi zingwe zosiyanasiyana zomwe zimafanana. Mwa iwo, zingwe zokhudzana ndi "MINI SAS" ndizofunikira koma zimatha kusokoneza. Lero tikambirana za "MINI SAS 8087 mpaka 8654 4i Chingwe"ndi"MINI SAS 8087 Chingwe" kukuthandizani kumvetsetsa momwe amagwiritsidwira ntchito komanso kusiyana kwawo.
I. Basic Understanding: Kodi MINI SAS ndi chiyani?
Choyamba, SAS (Serial Attached SCSI) ndi protocol yomwe imagwiritsidwa ntchito kulumikiza ndikuwongolera zida zakunja zamakompyuta, makamaka ma hard disk drive. Yalowa m'malo mwaukadaulo wakale wa SCSI. MINI SAS ndi mawonekedwe akuthupi a mawonekedwe a SAS, omwe ndi ang'onoang'ono kuposa momwe amalumikizirana ndi SAS ndipo atha kupereka maulumikizidwe apamwamba kwambiri m'malo ochepa.
Panthawi ya kusintha kwa MINI SAS, mitundu yosiyanasiyana ya mawonekedwe yatulukira, yomwe SFF-8087 ndi SFF-8654 ndi oimira awiri ofunika kwambiri.
MINI SAS 8087 (SFF-8087): Ichi ndiye chitsanzo chapamwamba cha cholumikizira chamkati cha MINI SAS. Ndi mawonekedwe a pini 36, omwe amagwiritsidwa ntchito kulumikiza bolodi (HBA khadi) ku ndege yakumbuyo kapena mwachindunji kuma hard drive angapo. Mawonekedwe amodzi a SFF-8087 amaphatikiza njira zinayi za SAS, iliyonse ili ndi bandwidth yongoyerekeza ya 6Gbps (malingana ndi mtundu wa SAS, imathanso kukhala 3Gbps kapena 12Gbps), motero bandwidth yonse imatha kufika ku 24Gbps.
MINI SAS 8654 (SFF-8654): Uwu ndi mulingo watsopano wolumikizira kunja, womwe nthawi zambiri umatchedwa Mini SAS HD. Ilinso ndi mapini 36 koma ndi yaying'ono komanso yophatikizika pamapangidwe. Amagwiritsidwa ntchito makamaka kulumikiza madoko akunja a zida, monga kuchokera pa seva yolandila kupita ku kabati yakunja ya disk. Mawonekedwe amodzi a SFF-8654 amathandizanso njira zinayi za SAS ndipo zimagwirizana ndi SAS 3.0 (12Gbps) ndi mitundu yapamwamba.
II. Core Analysis: MINI SAS 8087 mpaka 8654 4i Chingwe
Tsopano, tiyeni tiyang'ane pa liwu loyamba:MINI SAS 8087 mpaka 8654 4i Chingwe.
Kuchokera ku dzina, tikhoza kutanthauzira mwachindunji:
Mapeto amodzi ndi mawonekedwe a SFF-8087 (mawonekedwe amkati)
Mapeto ena ndi mawonekedwe a SFF-8654 (mawonekedwe akunja)
"4i" nthawi zambiri imayimira "njira 4 mkati", apa zitha kumveka ngati chingwechi chimanyamula kulumikizana kwathunthu kwa 4-channel SAS.
Kodi ntchito yaikulu ya chingwechi ndi yotani? - Ndi "mlatho" wolumikiza kusungirako kwamkati ndi kunja kwa seva.
Zochitika zodziwika bwino:
Tangoganizani kuti muli ndi seva ya nsanja kapena malo ogwirira ntchito okhala ndi khadi ya HBA pa bolodi la amayi lomwe lili ndi mawonekedwe a SFF-8087. Tsopano, muyenera kulumikiza kunja kwa SAS disk array cabinet, ndipo mawonekedwe akunja a disk array cabinet ndi chimodzimodzi SFF-8654.
Panthawi imeneyi, aMINI SAS 8087 mpaka 8654 4i Chingwezimabwera mumasewera. Mumayika mapeto a SFF-8087 mu khadi lamkati la HBA la seva, ndikulumikiza mapeto a SFF-8654 ku doko la nduna yakunja ya disk. Mwanjira iyi, seva imatha kuzindikira ndikuwongolera ma hard drive onse mu disk cabinet.
M'mawu osavuta, iyi ndi "kuchokera mkati mpaka kunja" mzere wolumikizira, kukwaniritsa kutumiza kwa data kosasunthika komanso kothamanga kwambiri kuchokera kwa woyang'anira SAS mkati mwa seva kupita ku chipangizo chosungira kunja.
III. Kumvetsetsa Kufananiza:MINI SAS 8087 Chingwe
Liwu lachiwiri lofunikira "MINI SAS 8087 Cable" ndi lingaliro lalikulu, kutanthauza chingwe chokhala ndi malekezero amodzi kapena onse awiri kukhala SFF-8087. Nthawi zambiri amagwiritsidwa ntchito polumikiza zida zamkati.
Mitundu yodziwika bwino ya MINI SAS 8087 Cable ikuphatikiza:
Mtundu wolumikizira mwachindunji (SFF-8087 ku SFF-8087): Mtundu wodziwika kwambiri, womwe umagwiritsidwa ntchito polumikizana mwachindunji pakati pa khadi ya HBA ndi ndege yakumbuyo ya seva.
Mtundu wa Nthambi (SFF-8087 mpaka 4x SATA/SAS): Mapeto amodzi ndi SFF-8087, ndipo malekezero ena amatuluka m'malo 4 odziyimira pawokha a SATA kapena SAS. Chingwechi nthawi zambiri chimagwiritsidwa ntchito kulumikiza khadi ya HBA ku ma drive 4 odziyimira pawokha a SATA kapena SAS osadutsa ndege yakumbuyo.
Mtundu wa nthambi yobwerera kumbuyo (SFF-8087 ku SFF-8643): Amagwiritsidwa ntchito kulumikiza makhadi akale a HBA okhala ndi mawonekedwe osinthidwa (monga SFF-8643) ku backplane kapena hard drive.
Kusiyana kwakukulu kuchokera ku 8087 mpaka 8654 chingwe:
Munda wofunsira: MINI SAS 8087 Chingwe chimagwiritsidwa ntchito makamaka mu chassis ya seva; pomwe 8087 mpaka 8654 Chingwe chimagwiritsidwa ntchito makamaka kulumikiza zida zamkati ndi zakunja.
Kuyika kwa ntchito: Yoyamba ndi chingwe cha "internal interconnection", pomwe chomaliza ndi chingwe cha "mkati-mlatho wakunja".
IV. Mwachidule ndi Kugula Malingaliro
MINI SAS 8087 mpaka 8654 4i Cable General MINI SAS 8087 Chingwe
Kuphatikizika kwa mawonekedwe Mapeto amodzi SFF-8087, mbali imodzi SFF-8654 Nthawi zambiri malekezero onse ndi SFF-8087, kapena mbali imodzi yotuluka.
Kugwiritsa ntchito kwakukulu Kulumikiza makabati okulitsa amkati ndi akunja a seva Kulumikizana kwagawo mkati mwa maseva ndi zida zosungira
Zochitika zogwiritsira ntchito DAS Yakunja Yosungirako (Direct Attached Storage) Kulumikiza khadi ya HBA kupita ku backplane, kapena kulumikiza mwachindunji ma hard drive
Mtundu wa chingwe Chingwe chakunja (nthawi zambiri chokhuthala, chotchinga bwino) Chingwe chamkati
Malingaliro ogula: Fotokozani zofunika: Kodi muyenera kulumikiza zida zakunja kapena kungopanga mawaya amkati?
Tsimikizirani zolumikizira: Musanagule, chonde fufuzani mosamala mitundu ya mawonekedwe pa seva yanu ya HBA khadi ndi kabati yokulitsa. Dziwani ngati ndi SFF-8087 kapena SFF-8654.
Samalani kumitundu: Onetsetsani kuti zingwe zimathandizira kuthamanga kwa SAS komwe mukufuna (monga SAS 3.0 12Gbps). Zingwe zapamwamba zimatha kutsimikizira kukhulupirika kwa chizindikiro ndi kukhazikika.
Kutalika koyenera: Sankhani kutalika koyenera kwa zingwe potengera kapangidwe ka kabati kuti musamakhale waufupi kwambiri kuti musalumikizane kapena motalika kwambiri kuti musasokoneze.
Kupyolera mu kusanthula pamwambapa, tikukhulupirira kuti mumamvetsetsa bwino za "MINI SAS 8087 mpaka 8654 4i Cable" ndi "MINI SAS 8087 Cable". Ndiwo "zotengera" zofunika kwambiri pomanga njira yosungiramo yodalirika komanso yodalirika. Kusankhidwa koyenera ndi kuzigwiritsa ntchito ndiye maziko owonetsetsa kuti dongosololi likuyenda bwino.
