  • Page 4: Chapter 1 Introduction

    Chapter 1 Introduction iSCSI iSCSI Compatible Hard Drive iSCSI (Internet Small Computer System Interface) is a standard to transmit data on an Ethernet network by encapsulating SCSI commands in TCP/IP protocol. Once the iSCSI drive is connected to the network by Ethernet cables, the drive is recognized as a local drive by computers or servers on the network.
