Is iSCSI faster than NFS?

Neither iSCSI nor NFS is inherently faster (they have similar overheads, etc). But certainly some arrays are better at block or NFS than others. Same with host initiators.

Is iSCSI faster than SMB?

Windows SMB/CIFS network shares may be slightly faster than iSCSI for large file transfers. The opposite may be true for small file copies. Many variables such as source and target hardware may impact the performance, so your results may vary.

Do I need iSCSI initiator?

The need for a NIC-based TCP/IP offload engine (TOE) has declined as servers have gained more powerful processing cores. A hardware iSCSI initiator may still be useful for data protection, when booting a server from a local disk, or for security, if the card has built-in encryption capabilities.

How do I find my iSCSI IP address in Linux?

Determine the iSCSI port names using the # ifconfig -a command. Set the IP address for the iSCSI initiator ports. The initiator ports should be present on the same subnet as the iSCSI target ports. Note: Be sure to set the address for both iSCSI initiator ports.

What is open iSCSI?

The Open-iSCSI project provides a high-performance, transport independent, implementation of RFC 3720 iSCSI for Linux. Open-iSCSI is partitioned into user and kernel parts. ... The kernel part implements iSCSI data path (that is, iSCSI Read and iSCSI Write), and consists of several loadable kernel modules and drivers.

Does Linux support iSCSI?

This driver implements currently the Sendtargets discovery method. Target implementations: iSCSI enterprise target is the open source target implementation for Linux. It based on the Ardis iSCSI Linux implementation and requires the 2.6.
