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. 8 Introduction
