SAN will enable almost any application that moves data around the network to perform better. Just like conventional subnets SANs add bandwidth for specific functions without placing a load on the primary network. In this fashion SAN compliment LANs and WANs. SAN also enable higher performance solutions such as data warehousing. SAN are really pervasive and applicable to many networking enironments.
SAN technology enables the network architecture of shared multihost storage connecting all storage devices as well as interconnecting remote sites. This will soon be standard configuration for centralized networks running mission critical applications. Both disk and tape operations are centralized. SAN architecture holds the keys to the future.
The benefits of a SAN network architecture are huge and will cause many sites to adopt this methodology of attaching storage and transferring data. In a cluster the SAN provides the data pipe allowing storage to be shared. Microsoft cluster server which is an availability cluster shares a single array between two servers attached via SCSI SAN. SAN provide the best interconnects allowing storage mirroring , remote clustered storage and other high availability data protection solutions. SAN do not impact the primary network or the servers and they provide redundancy. SAN make a very efficient transmission medium. Disaster protection systems can be built on remote vaulting (backup) processes or with high availability remote array mirroring.
Storage is getting to be as complex as servers and networks. At the other end of the technology spectrum is tape based storage which provides a low cost convenient alternative to disk storage. But the heart of the action these days revolves around disk based storage systems outside the computer. The hottest storage battleground is not storage hardware but software , switches and other components that meld the storage devices into intelligent network and keep them online.
San technology is part of the larger challenge of establishing a full storage networking management strategy. Careful consideration should be given to choosing a vendor or partnet that is capable of implementing the full range of benefits if storage management. These benefits include :
1) 24 x 7 x 365 availability
2) Scalability
3) Data sharing across different architectures
4) Storage access at all times and from all locations
5) Better performance
6) Cost reductions
7) Improved security
8) Significantly better data protection
9) Verifiable and consistent data integrity
Tivoli in partnership with many of the leading storage management and SAN vendors had developed and planned for the technology required to ensure successful implementation of SAN. Tivoli is developing new products that will be essential to exploit the information grid in all its capabilities. The key areas where installations must be prepared for SAN implementation and also for storage managemenet fulfillment are :
1) Application management
2) Data management
3) Resource management
4) Network management
5) Element management
