Kushanduka kweSAS Connector Technology: Kuchinja Kwekuchengetedza Kubva Pamwe Chete kuenda kuHigh-Speed Serial
Masisitimu ekuchengetera zvinhu emazuva ano haangokure padanho re terabit chete, ane mwero wekutamisa data wakakwira, asiwo anoshandisa simba shoma uye anotora nzvimbo shoma. Masisitimu aya anodawo kubatana kuri nani kuti ape kuchinjika kwakanyanya. Vagadziri vanoda kubatana kudiki kuti vape mwero wekutamisa data unodiwa parizvino kana mune ramangwana. Uye zvinotora nguva inopfuura zuva kuti specification iberekwe, ikure uye ikure zvishoma nezvishoma. Kunyanya muindasitiri yeIT, chero tekinoroji iri kuramba ichivandudzika uye ichichinja, uye SAS (Serial Attached SCSI, Serial SCSI) specification haisi inosiyana. Semutsivi we SCSI yakafanana, SAS specification yave iri mumaonero evanhu kwenguva yakati.
Mumakore ese SAS yagara iripo, magadzirirwo ayo agara achivandudzwa. Kunyangwe protocol iri pasi payo isina kuchinja zvakanyanya, magadzirirwo emaconnector ekunze akachinja kakawanda. Uku kugadziriswa kwakaitwa neSAS kuti ienderane nemamiriro emusika. Semuenzaniso, kushanduka kwemagadzirirwo emaconnector akadai seMINI SAS 8087, SFF-8643, uye SFF-8654 kwakachinja zvakanyanya macabling solutions sezvo SAS yakachinja kubva pa parallel kuenda kune serial technology. Kare, parallel SCSI yaigona kushanda kusvika ku320 Mb/s pamusoro pemachannel gumi nematanhatu mune imwe chete-ended kana differential mode. Parizvino, SAS 3.0 interface, iyo ichiri kushandiswa zvakanyanya mu enterprise storage, inopa bandwidth inokurumidza kaviri kupfuura SAS 3 isina kukwidziridzwa kwenguva refu, inosvika 24 Gbps, inova inenge 75% yebandwidth ye common PCIe 3.0 x4 solid-state drive. MiniSAS HD connector yazvino inotsanangurwa muSAS-4 specification idiki muhukuru uye inogona kuwana density yakakwira. Saizi yechinobatanidza cheMini-SAS HD chazvino ihafu yechinobatanidza cheSCSI chekutanga uye 70% yechinobatanidza cheSAS. Kusiyana netambo yeSCSI yekutanga yakafanana, SAS neMini-SAS HD zvese zvine nzira ina. Zvisinei, pamwe nekumhanya kwakanyanya, density yakakwira, uye kuchinjika kukuru, kunewo kuwedzera kwekuoma. Nekuti chinobatanidza chidiki, vagadziri vetambo, vanounganidza tambo, nevagadziri vemasisitimu vanofanirwa kunyatsoteerera ma parameter ekuvimbika kwechiratidzo chekubatanidza tambo yese.
Matambo emhando dzese eSAS nemaconnector, zviri nyore chaizvo kuita kuti zvitaridzike zvakanaka kwazvo… Mangani awakaona? Anoshandiswa mumaindasitiri, uye ayo ezvigadzirwa zvevatengi? Semuenzaniso, tambo yeMINI SAS 8087 kusvika 4X SATA 7P Male, tambo yeSFF-8643 kusvika SFF-8482, tambo yeSlimSAS SFF-8654 8i, nezvimwewo.
Upamhi (kuruboshwe, pakati) hwetambo yeMini-SAS HD hunosvika 70% yetambo yeSAS (kurudyi).
Havasi vese vagadziri vetambo vanogona kupa masaini ekumhanya kwepamusoro kuti vasangane nezvinodiwa zvekuchengetedza masaini ehurongwa hwekuchengetedza. Vagadziri vetambo vanofanirwa kupa mhinduro dzemhando yepamusoro uye dzinodhura zvishoma kune masisitimu ekuchengetedza azvino. Semuenzaniso, tambo yeSFF-8087 kuenda kuSFF-8088 kana tambo yeMCIO 8i kusvika 2 OCuLink 4i. Kuti vagadzire zvikamu zvetambo zvinomhanya zvakanyanya uye zvakagadzikana, zvinhu zvakawanda zvinofanirwa kufungwa nezvazvo. Kuwedzera pakuchengetedza mhando yekugadzirisa uye maitiro ekugadzirisa, vagadziri vanofanirwawo kunyatsoteerera ma parameter ekuchengetedza masaini, izvo chaizvo zvinoita kuti tambo dzemidziyo yekuchengetera masaini dzikwanise kushandiswa nhasi.
