Security and Reliability

NAS is an independent system which shares storage and is connected directly to a network that is directly accessible by a number of heterogeneous customers or other servers. NAS fiel servers are servers specifically designed to download files and services management of any application server.

• Due to the ubiquity of the internet
• The massive growth of e-mails
• Customer needs that require information at any time, ever richer in content, images, audio, video, clips and virtual private networks for e-commerce, datawarehousing and ERP application on the intranet.

• With NAS can be added storage without disrupting the network. Improving up-time considerably
• NAS architecture is compatible with the following operating systems: NT, Unix, Netware, etc.
• One of the main benefits that  has NAS is allowing customers to access directly without being redirected to the application server
• Performance: data are store directly by clients without intervention of the server
• Availability: Resilience to failures. Currently some data have become critical to the business, then these data should be safe and reliable. This calls for an SLA (Standard Level Accuracy) 99.9% (8 hours of downtime per year). In other cases, some applications require high availability of data such as the 99.99% (1 hour of downtime per year) and recover from failures of hardware, software and implementing change within 30 seconds. 
• Easy to retrieve information remotely. 
• Cost: HSM migration to tape for low cost data used infrequently. 
• Scalability: Includes modular scalability, file servers can be attached directly to the network without stopping the applications that are already running. 
• Interoperability: NAS is able to support heterogeneous clients (such as NT and Unix stations). To share the same network data from a server attached. 
• Advantages: NAS is ideal for document management, transaction-based applications. 

In summary NAS is ideal for working with documents, handling of files based transactions and applications.
