Network-attached storage (NAS) is hard disk storage that is set up with its own network address rather than being attached to the department computer that is serving applications to a network’s workstation users.By removing storage access and its management from the department server, both application programming and files can be served faster because they are not competing for the same processor resources.Fibre Channel SANs are the de facto standard for storage networking in the corporate data center because they provide exceptional reliability, scalability, consolidation, and performance.Fibre Channel SANs provide significant advantages over direct-attached storage through improved storage utilization, higher data availability, reduced management costs, and highly scalable capacity and performance.A storage area network can use existing communication technology such as IBM’s optical fiber ESCON or it may use the newer Fibre Channel technology.Some SAN system integrators liken it to the common storage bus (flow of data) in a personal computer that is shared by different kinds of storage devices such as a hard disk or a CD-ROM player.On Windows, Win Dump can be used; it’s a port of tcpdump to Windows.You must have a root or super user authority to use TCPdumps in UNIX like envrionment.
A storage area network is usually clustered in close proximity to other computing resources such as IBM Power5 boxes but may also extend to remote locations for backup and archival storage, using wide area network carrier technologies such as ATM or SONET .Network-attached storage consists of hard disk storage, including multi-disk RAID systems, and software for configuring and mapping file locations to the network-attached device.Network-attached storage can be a step toward and included as part of a more sophisticated storage system known as a storage area network (SAN).It allows the user to intercept and display TCP/IP and other packets being transmitted or received over a network to which the computer is attached.
Tcpdump works on most Unix-like platforms: Linux, Solaris, BSD, Mac OS X, HP-UX and AIX among others.
DHCP also supports a mix of static and dynamic IP addresses.
