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.
