Fibre Channel switches form the backbone for storage-area networks, but how does Fibre Channel compare to ATM and Gigabit Ethernet?
Potential benefits of network-attached storage (NAS) include faster data access, easier administration, and no-brainer configuration.
Network-attached storage (NAS) connects directly to the network and is optimized for better overall data accessibility. The system has a processor and its own operating system to allow network connectivity. The ability of NAS servers to connect anywhere on a LAN allows network performance to be balanced by placing storage close to the users who need to have data readily accessible.
Long talked about under the code name Wolfpack, Microsoft`s Windows NT clustering is finally here and it promises to propel NT into the enterprise arena. Clustering will enable organizations that deploy NT for critical production systems to get closer to the level of reliability and availability offered by other enterprise operating systems, such as Unix, OpenVMS, and OS/390. In the process, however, system administrators will have to rethink their approach to storage.
As we approach the release date of NT 5.0, debate over NT`s storage capabilities is heating up. From a storage perspective, NT 4.0 lacks the capabilities to support the enterprise. Drawbacks include:
A quick review of optical disc technologies and market forces, including emerging formats such as the controversial DVD.
Providing continuous data access goes beyond disaster recovery and requires a solid business continuity plan.
Developing an enterprise storage management strategy entails more than cobbling a collection of "point products."
Network-attached storage (NAS) promises a number of benefits, including faster file services, increased reliability, and lower costs, but it`s been a long time coming.
Faster data access rates, dramatic cost savings, fewer tape cartridges and libraries, and more available floor space are just a few of the potential benefits of implementing virtual tape systems in large data centers. (For an introduction to this emerging technology, see "The Virtues of Virtual Tape," InfoStor, December 1997, p. 38.)
