IP SANS: An introduction to iSCSI, iFCP, and FCIP protocols for storage area networks. Address : ACC Pirivu, Navakkarai(PO), Mavuthampathy Village, In this paper, we present architectures and features of SANtopia that allows multiple machines to access and share disk and tape devices on a Fibre Channel or SCSI storage network in Linux system. The ob-, jective of a SAN is to allow multiple servers access to a, pool of data storage in which any server can potentially, access any storage unit. These products further enhance the ability of SAN designers to craft shared storage configurations that leverage IP exclusively or integrate both IP and Fibre Channel into a heterogeneous storage network. Q�8��"B����,����%>g� Data can be directly written into application, memory through a steering and data synchronization, security across the Internet. Solutions to this problem have been offered by. New York : Wiley. The distant SANs appear as local storage, entities. While vendors attempt to debug and certify SAN configurations in advance, problems naturally arise during installation or subsequent operation.
