Glossary of Storage-related Terms and Acronyms D V Virtualization: The creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources. The Cisco NSS refers to virtualization as a way of aggregating storage between devices. Virtualized storage occurs when storage is exported to the network as a disk drive or an array and is then imported by a master NSS. The master NSS then uses the newly imported storage to create a single JBOD. VLAN: Virtual Local Area Network (LAN). A logical group of user stations, servers, and other network devices that appear to be on the same LAN, regardless of their physical location. You can use the MAC addresses or IP addresses to interconnect the workstations on the LAN. You can access and control the switches directly from a console port or via the LAN using IP. W Well Known Ports: IANA assigns TCP and UDP port numbers to specific uses. The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports, and the Dynamic and/or Private Ports.The Ports that are popular (well known) are those in the range 0 to 1023. WINS: Windows Internet Naming Service. This is part of the Microsoft Windows NT Server. It manages the association of workstation names and locations with Internet addresses. The user or an administrator does not have to be involved in each configuration change. X XFS: A high-performance journaling filesystem created by Silicon Graphics for their IRIX operating system. XFS has been merged into the mainline Linux 2.4 and 2.6 kernels, making it almost universally available on Linux systems. Installation programs for the SuSE, Gentoo, Mandriva, Slackware, Zenwalk, Fedora, Ubuntu and Debian Linux distributions all offer XFS as a choice of filesystem. FreeBSD gained read-only support for XFS in December 2005 and in June 2006 experimental write support was introduced to FreeBSD-7.0-CURRENT.
