San Implementation Essay -- essays research papers fc

SAN implementation oer Gigabit Ethernet A storehouse Area Network is virtualized memory.A entrepot area network (SAN) is a dedicated, centrally managed, situate information infrastructure, which enables any-to-any interconnection of servers and remembering transcriptions. A SAN can be configured to provide a nearly infinite pool of storage that you can resurrect and move between servers as they need it. The storage can be added to and removed without requiring the server to be rebooted. The services provided by the server continue to work without interruption.The primary purpose for implementing a SAN is to provide a large storage pool that multiple hosts could access. Common storage configurations involve direct attachment of storage to a host. This storage is only available for map by that host. If there were another host that needed storage, you would need to buy additional storage to store on that host. The host with excess capacity would not be able to share its storag e with another host.In a SAN, all networked devices share storage capacity as peer resources they are not the exclusive property of any one server. You can use a SAN to connect servers to storage, Servers to each other, and storage to storage through hubs or switches. A SAN carries only I/O traffic between servers and doesnt carry any general-purpose traffic such(prenominal) as e-mail. Storage area networks remove data traffic, like backup processes, from the production network giving IT managers a strategic way to improve system performance and application availability.As SAN technology develops, it is growing beyond the use of any one kind of technology. A SAN can be configured to use a number of protocols such as IP or Fibre Channel over a network medium like Ethernet or ATM. FC over Ethernet supports up to 1.06 Mbps. Emerging standards that are still being defined include Gigabyte System Network(GSN) which promises full-duplex 6.4 Mbps over a 40 meter copper cable.Storage area networks improve data access. Using Fibre Channel connections, SANs provide the high-speed network communications and distance needed by remote workstations and servers to soft access shared data storage pools. IT managers can more easily centralize management of their storage systems and consolidate backups, increasing overall system efficiency. The change magnitude distances provided by Fibre Channel technology make it easier to ... ... all of your different hosts and handle the conversion and routing of data between the servers and their virtual disks.The phrase SAN implementation over Gigabit Ethernet is a misnomer. You are using FC or SCSI disks at all times. The SAN is implemented using the common Fibre Channel or SCSI technology. The hosts unless would use a variety of methods to attach to the storage pool. The usual connection methods try to avoid introducing bottlenecks between the server and the storage pool. If you combine the different colligate from the servers toge ther over a 1000Base switch, you would make better use of the available bandwidth to the storage.Using Gigabit Ethernet in this way makes for an excellent low-cost connection to storage resources. Since umteen customers already have a Ethernet network in place the additional cost of the GSN capable switch is the only additional cost. Once the switch is given over to the SAN, the benefits of a SAN solution can be pushed out to more client computers in the company.Bibliographyhttp//www.zdnet.com/eweek/reviews/1201/01gig.htmlReferencehttp//www.iol.unh.edu/consortiums/ge/index.htmlhttp//www.cisco.com/warp/public/729/gigabit/index.shtml
