SAN
SAN (StorageAreaNetwork) мрежа от области за съхранение
In1991,IBMintroducedESCON(EnterpriseSystemConnection)technologyintheS/390server.Itisaconnectionmethodforserverswithamaximumtransmissionrateof17MB/stoaccessstoragebasedonopticalfibermedia.Onthisbasis,amorepowerfulESCONDirector(FCSWitch)wasfurtherintroduced,andasetofthemostprimitiveSANsystemwasconstructed.
SANstoragehascreatedanetworkedstorage.Storagenetworkingconformstothetrendofnetworkedcomputerserverarchitecture.ThesupportingtechnologyofFC-SANisFCFiberChannel(FCFiberChannel)technology.ItisastandardintegrationestablishedbyANSIfornetworkandchannelI/Ointerfaces.FCtechnologysupportsHIPPI,IPI,SCSI,IP,ATMandotheradvancedprotocols.Itsbiggestfeatureistoseparatethecommunicationprotocolofthenetworkandequipmentfromthephysicaltransmissionmedium,sothatmultipleprotocolscanbetransmittedsimultaneouslyonthesamephysicalconnection.Ofcourse,SANcanalsobedeployedusingIPchannels---IP-SAN.
ThehardwareinfrastructureofFC-SANisFibreChannel,andtheSANbuiltwithFibreChannelconsistsofthefollowingthreeparts:
(1) Оборудване за съхранение и архивиране: включително ленти и дискове И CD библиотека и др.
(2) Компоненти за мрежова връзка на FibreChannel: включително адаптерни карти за хост шина, драйвери, оптични кабели, концентратори, комутатори, мостове между FibreChanne и SCSI
(3)Applicationandmanagementsoftware:includingbackupsoftware,storageresourcemanagementsoftwareandstoragedevicemanagementsoftware.
Предимствата на FC-SAN:
(1) Лесно внедряване в мрежа;
