MiniSAS HD SFF-8644 kugeza kuri QSFP 40G SFF-8436 Insinga yo gupakira seriveri

Ni ibihe bintu biranga insinga za SAS n'insinga za SAS?

Insinga ya SAS ni ahantu ho kubika amakuru muri disiki. Iyi disiki niyo ikoreshwa cyane, amakuru yose n'amakuru bigomba kubikwa kuri disiki. Umuvuduko wo gusoma amakuru ugenwa n'aho amakuru ahurira. Mu bihe byashize, twahoraga tubika amakuru yacu binyuze muri SCSI cyangwa SATA na disiki zikomeye. Ni ukubera iterambere ryihuse ry'ikoranabuhanga rya SATA n'inyungu zitandukanye abantu benshi bazatekereza niba hari uburyo bwo guhuza SATA na SCSI, kugira ngo ibyiza byabyo byombi bishobore gukinwa icyarimwe. Muri iki gihe, SAS yaragaragaye. Ibikoresho byo kubika amakuru bishobora kugabanywamo ibice bitatu by'ingenzi, ari byo, hagati na hafi (Near-Line). Ibikoresho byo kubika amakuru menshi ahanini ni Fibre channel. Bitewe n'umuvuduko wo kohereza amakuru vuba wa Fibre channel, ibikoresho byinshi byo kubika amakuru menshi bikoreshwa mu kubika amakuru menshi mu gihe nyacyo. Ibikoresho byo kubika amakuru biri hagati ahanini ni SCSI, kandi bifite amateka maremare, bikoreshwa mu kubika amakuru menshi y'ingenzi yo ku rwego rw'ubucuruzi. Mu buryo buhinnye nka (SATA), ikoreshwa mu kubika amakuru menshi atari ay’ingenzi kandi igamije gusimbuza kubika amakuru mbere hakoreshejwe kaseti. Akamaro keza k’ibikoresho byo kubika Fibre Channel ni uko byohereza amakuru vuba, ariko bifite igiciro kiri hejuru kandi biragoye kubibungabunga; ibikoresho bya SCSI bifite uburyo bwo kubigeraho bwihuse kandi bufite igiciro kiringaniye, ariko ni bike cyane, buri karita ya SCSI ihuza ibikoresho bigera kuri 15 (umuyoboro umwe) cyangwa 30 (imiyoboro ibiri). SATA ni ikoranabuhanga rigenda ritera imbere vuba mu myaka ya vuba aha. Akamaro kayo kanini ni uko ihendutse, kandi umuvuduko wayo ntutinda cyane ugereranije n’umuyoboro wa SCSI. Hamwe n’iterambere ry’ikoranabuhanga, umuvuduko wo gusoma amakuru wa SATA urimo kwegera no kurenga umuyoboro wa SCSI. Byongeye kandi, uko disiki ikomeye ya SATA igenda ihenda kandi ihenze cyane, ishobora gukoreshwa buhoro buhoro mu kubika amakuru. Rero uburyo busanzwe bwo kubika amakuru kuko ukurikije imikorere n'ubudahangarwa, hamwe na disiki ikomeye ya SCSI na fibre optique nk'urubuga nyamukuru rwo kubika amakuru, SATA ikoreshwa cyane cyane kuri mudasobwa zidafite akamaro cyangwa mudasobwa zikoresha mudasobwa, ariko bitewe n'iterambere ry'ikoranabuhanga rya SATA n'ibikoresho bya SATA, ubu buryo burimo guhinduka, abantu benshi batangiye kwita kuri SATA muri ubu buryo bwo guhuza amakuru.
