Managing iSCSI Storage 5
ESXi systems include iSCSI technology to access remote storage using an IP network. You can use the
vSphere Web Client, commands in the esxcli iscsi namespace, or the vicfg-iscsi command to congure
both hardware and software iSCSI storage for your ESXi system.
See the vSphere Storage documentation for additional information.

iSCSI Storage Overview
With iSCSI, SCSI storage commands that your virtual machine issues to its virtual disk are converted into
TCP/IP protocol packets and transmied to a remote device, or target, on which the virtual disk is located.
To the virtual machine, the device appears as a locally aached SCSI drive.
To access remote targets, the ESXi host uses iSCSI initiators. Initiators transport SCSI requests and responses
between ESXi and the target storage device on the IP network. ESXi supports the following types of
initiators.
n
Software iSCSI adapter - VMware code built into the VMkernel. Allows an ESXi host to connect to the
iSCSI storage device through standard network adapters. The software initiator handles iSCSI
processing while communicating with the network adapter.
n
Hardware iSCSI adapter - Ooads all iSCSI and network processing from your host. Hardware iSCSI
adapters are broken into two types.
n
Dependent hardware iSCSI adapter - Leverages the VMware iSCSI management and conguration
interfaces.
