I- SAN kwikota yokunxibelelana kwekhompyutha ngokuqhelekileyo ibhekisela ekunxibelelaneni kwendawo yokunxibelelana kodwa ingabhekisela kwinkqubo yokunxibelelana kwendawo.
Inethiwekhi yendawo yokugcinwa yintengiso yendawo yenethiwekhi yendawo (i-LAN) eyenzelwe ukusingatha ukudluliselwa kwedatha okukhulu kunye nokugcinwa kwenqwaba yolwazi lwedijithali. I-SAN isekela ngokugcinwa kwedata, ukubuyisela nokuphindaphinda kwiinkcukacha zoshishino usebenzisa amaseva aphezulu, iindawo ezininzi ze-disk kunye ne-interconnect technology.
Amanethiwekhi okugcina asebenze ngokwahlukileyo kunamanethiwekhi athengelwano lwabaxhasi ngenxa yohlobo olulodwa lomthwalo wabo womsebenzi. Ngokomzekelo, amanethiwekhi asekhaya ngokuqhelekileyo abonisa abasebenzisi abaphengulula i-Intanethi, ebandakanya amanani amancinci wedatha abangela amaxesha ahlukeneyo, kwaye unokuvuselela ezinye izicelo ukuba zenzeke zilahleke. Amanethiwekhi okugcina, ngokuthelekisa, kufuneka aphathe amanani amaninzi eenkcukacha eziveliswe kwizicelo ezininzi kwaye akakwazi ukukwazi ukulahlekelwa nayiphi na idatha.
Inethwekhi yendawo yenethiwekhi iqoqo leekhomputha zeekhompyutheni ezisetyenzisiweyo ezisetyenziselwa ukusetyenziswa kwezixhobo zokucwangcisa ezifuna ukusebenza ngokukhawuleza kwenethiwekhi yendawo ukuze kuxhaswe i-computing counter and output to users users.
I-Fiber Channel kunye neSCSI
Iikhompyutha ezimbini ezibalulekileyo zonxibelelwano kumanethiwekhi okugcina - I- Fiber Channel kunye ne-intanethi ye-Intanethi yeComputer Systems Systems (iSCSI) - zombini isetyenziswe ngokubanzi kwi-SANs kwaye ikhuphisana kunye neminyaka emininzi.
I-Fiber Channel (FC) yaba yinto ehamba phambili kwi-network network ye-SAN phakathi ne-1990. Iinqununu zeSatifikethi zeSatifikethi zeFiber ziqulethe i-hardware eneenjongo ezikhethekileyo ezibizwa ngokuba yi- Fiber Channel ezitshintshiweyo ezixhuma ukugcinwa kwi-SAN kunye ne-HBAs ye- Fiber Channel (i-adapters ibhasi ye-host) ezidibanisa ukutshintshela kwiikhomputha zeseva. Ukuqhagamshelana neC FC kunika amaxabiso e-data phakathi kwe-1 Gbps kunye ne-16 Gbps.
I-iSCSI yenziwe njengendleko ephantsi, ukusetyenziswa okuphantsi kweShift Fiber kwaye yaqala ukukhula ekuthandeni phakathi ne-2000. I-iSCSI isebenza nge-switches ye- Ethernet kunye nokuxhamla ngokomzimba endaweni yezinto ezikhethekileyo ze-hardware ezakhelwe ngokukodwa ukulayisha imithwalo yomsebenzi. Inika amaxabiso e-10 Gbps kunye nephezulu.
Izibheno ze-iSCSI ngokukodwa kumashishini amancinci aqhelekanga abaqeqeshiweyo ekulawuleni ubuchwephesha be-Fiber Channel. Ngakolunye uhlangothi, imibutho esele ifunyenwe kwiFiber Channel ukusuka kwimbali ingaziveki inyanzelekile ukuba ifake iSCSI kwindawo yazo. Ifomu enye yeFC ebizwa ngokuba yiFiber Channel phezu kwe-Ethernet (FCoE) yaphuhliswa ukuba iyanciphise iindleko zeC FC ngokuphelisa isidingo sokuthenga i-HBA hardware. Akuyiyo yonke i-Ethernet yokutshintsha i-FCoE inkxaso, nangona kunjalo.
SAN Products
Abenzi abaziwayo bezixhobo zokusebenza zenethiwekhi ziquka i-EMC, HP, IBM, kunye ne-Brocade. Ukongeza kwiintshi ze-FC kunye nee-HBAs, abathengisi nabo bathengisa iindawo zokugcina kunye neengcambu zokungena kwi-disk media. Iindleko zezixhobo ze-SAN ezivela kumakhulu ambalwa ukuya kumawaka eedola.
SAN vs. NAS
I-teknoloji ye-SAN iyafana kodwa ihluke kwi-teknoloji yokugcina intambo (NAS). Nangona ii-SAN ziqhelise ngokuqhelekileyo iinkqubo zee-network zenqanaba eliphantsi lokudlulisa iibhloko zedisk, i- NAS ifowuni isebenza ngaphezu kweTCP / IP kwaye ingadibaniswa ngokufanelekileyo kwiinkqubo zekhompyutheni zasekhaya .
