• IP Telephony Storage is a leading technology for cost-effective and easily-deployable network storage.

• IP Telephony Storage (using Network Attached Storage) will gain acceptance as an entry-level storage tool and a viable low-cost alternative.

•Network path for redundant and scalable storage.

•Network-attached storage (NAS) is file-level computer data storage connected to a computer network providing data access to heterogeneous clients.

•Network-attached storage removes the responsibility of file serving from other servers on the network.

• They provide access to files using network file sharing protocols such as NFS, SMB or AFP.

*TOTAL COST OF OWNERSHIP

2U External Hot Swap SCSI cabinet with seven 146 GB SCA U320 hard drives (~730 GB RAID 5) and a U320

Single Channel RAID controller = $10.27 per Gigabyte of storage.

1U IP Telephony Storage with four 250 GB ATA drives (~750 GB) = $6.93 per Gigabyte of storage.

•Faster networks will promote more use of networked storage to replace desktop PC storage for much-easier storage administration.

• Networking technology advances and deployment may accelerate the separation of storage and server components of IP Telephony Storage.

•NAS is useful for more than just general centralized storage provided to client computers in environments with large amounts of data.

• NAS can enable simpler and lower cost systems such as load-balancing and fault-tolerant email and web server systems by providing storage services.

•A clustered NAS is a NAS that is using a distributed file system running simultaneously on multiple servers.

•Clustered NAS, like a traditional one, still provides unified access to the files from any of the cluster nodes, unrelated to the actual location of the data.

*IP Telephony Storage should be considered a prime component for any enterprise telephony application network design that requires 300 GB+ of storage beyond what is available on the local host server.
