8 Introduction

Terms and Definitions

The following sections describe the terms used in this document.

PowerVault Storage System

Throughout this document, the term PowerVault storage system refers to the

individual storage unit. The term PowerVault storage solution refers to the

configuration of the server separately or together with the storage arrays.

iSCSI

iSCSI is a standard that carries SCSI commands through Transfer Control

Protocol/Internet Protocol (TCP/IP)—a protocol that enables transport of

block data over IP networks, without the need for a specialized network

infrastructure, such as Fibre Channel.

In the context of system storage, iSCSI enables any client/machine (Initiator)

on an IP network to contact a remote dedicated server (Target) and perform

block I/O on it just as it would perform on a local hard disk.

iSNS

Microsoft iSCSI Internet Storage Name Service (iSNS) is a service that

processes iSNS registrations, deregistrations, and queries through TCP/IP from

iSNS clients and also maintains a database of these registrations (similar to a

DNS server). A common use for Microsoft iSNS server is to allow iSNS clients

(Initiators and Targets) to register themselves and to query for other registered

iSNS clients. Registrations and queries are transacted remotely over TCP/IP.

You can download and install the iSNS server from the Microsoft Support

website at support.microsoft.com on a separate server that does not have

Microsoft iSCSI Initiator or Target installed.

NOTE: For details about installing and configuring the iSNS server, see "Appendix"

on page 39.
