ISCSI technology is a SCSI instruction set that is developed by IBM and used by hardware devices to run on the upper layer of the IP protocol, this command set allows you to run the SCSI protocol on an IP network so that it can select routes on high-speed Gigabit Ethernet. The biggest benefit of iSCSI is that it can provide a fast network environment. Although there are still some gaps between its performan

Linux Mounted iSCSI StorageiSCSI is provided to Linux mounts in two ways, an IP map over the iSCSI protocol, and a file-sharing NFS mount. Where the IP mapping via the iSCSI protocol is mounted to Linux as a disk, the IP mapping also requires partitioning the disk and formatting the partition.Mount Step:1: Check iSCSI

iSCSI Network Storage ServicesiSCSI implements networked storage, which provides the storage end called target, using the storage end called initiator. Storage space is available on target, initiator is responsible for connecting iSCSI devices, creating file systems in iSCSI devices, and accessing data, which looks like a hard drive on the initiator.Server-side c
