NFS is a Remote/Network File System. iSCSI is a local file system.
iSCSI is just transporting the SCSI protocol over a "different" physical layer sort of like how you can transport SCSI over really really fat parallel SCSI cables, PATA cables, or SATA cables. (That is, pSCSI, sSCSI, and iSCSI are identical and they are all filesystemless block transport protocols). --- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume. >-----Original Message----- >From: sqlite-users [mailto:sqlite-users- >boun...@mailinglists.sqlite.org] On Behalf Of Dennis Clarke >Sent: Tuesday, 14 August, 2018 13:10 >To: sqlite-users@mailinglists.sqlite.org >Subject: Re: [sqlite] Safe sqlite over remote filesystem? > > >Read all of this repeatedly.
