I. Overview of iSCSI

ISCSI (Internet SCSI) technology, developed by IBM Research, is a set of SCSI instructions that can be run on the upper layer of the IP protocol for use by hardware devices, which can enable the SCSI protocol to run on an IP network. Allows routing to be routed on such high-speed Gigabit Ethernet. iSCSI technology is a new storage technology that combines existing SCSI interfaces with Ethernet (Ethernet) technology to enable servers to Exchange data with storage devices that use IP networks.

iSCSI is a TCP/IP-based protocol used to establish and manage inter-connectivity between IP storage devices, hosts, and clients, and to create a storage area network (SAN). SAN makes it possible for the SCSI protocol to be applied to high-speed data transmission networks, which are performed across multiple data storage networks at block level (block-level). The SCSI architecture is based on the C/S mode, and the typical application environment is that the devices are close to each other and the devices are connected by a SCSI bus.

The main functionality of ISCSI is the encapsulation and reliable transmission of large amounts of data between host systems (initiator initiator) and storage devices (target targets) on TCP/IP networks.

The topology of the complete iSCSI system is as follows:

Like RAID technology, iSCSI is divided into two types of hardware iSCSI and software iSCSI.

Ii. DSS V7 support for iSCSI

DSS supports both hardware and software iSCSI. It can act as an iSCSI server, or it can serve as an iSCSI initiator (client program).

In addition to DSS V7, Windows Server 2012 and Windows Server 2016 also have software iSCSI target programs built in, and of course users can install third-party programs to perform simulations of ISCI target programs.

Third, the operation process

As with the previous NAS operation, the author restores the virtual to the initial snapshot before the operation, and adds a 40G hard drive.

Access the DSS01 host through the web.

1. Generating Volume Group
