The DAFS protocol is a new file-access protocol designed to take advantage of emerging RDMA (remote direct memory access) interconnect technologies such as InfiniBand, VI and iWARP. The protocol will dramatically enhance the performance, reliability and scalability of web farm, compute farm, e-commerce and database applications in data center environments.

The DAFS protocol was created by the DAFS Collaborative—a group of more than 85 companies. The DAFS protocol specification v1.0 was completed in September 2001, and submitted to the IETF as an Internet Draft. The DAFS API specification v1.0 was completed in November 2001. This completed the mission of the DAFS Collaborative.

DAFS-related industry initiatives are continuing in the DAT Collaborative (defining RDMA Transport APIs), and the DAFS Implementers Forum in the Storage Networking Industry Association (SNIA). The charter of the DAFS Implementers Forum is to advance the development, delivery and promotion of interoperable DAFS storage networking solutions. File system is accessible using ssh secure shell and other remote connections shells.

Data or file recovery is the process of retrieving any data from the cause of damage, corrupted, or unable to access any secondary storage media when it is unable to be accessed from a normal way. Normally, the data are being saved from different storage media like hard drives, different storage tapes, Compact Disks, DVDs, RAID, and external devices. Recovery of any file may be needed because of the damage that has done physically to the storage device. The basic situation for any sort of file recovery involves the failure of the operating system or may be some other situation. Operating system failures most often occur due to wrong partition of hard drive space or may be giving less space to the partition where operating system is installed. Another situation may be the failure of level of disk where the data cannot be read easily. There is best cheap software which can recover any file or data which has lost due to some crash or system failure. But the best files recovery software is MDW recovery. It is top most file recovery services and software provider. It provides its customer with so many different utilities including MDW recovery to recover from any crash of software or hardware. There services have helped so many customers and different business to recover their most important data. Data recovery services can retrieve any data from different failures like hard disk failure, system failure etc. They also provide services like file repair services, data recovery services, E-mail recovery services and backup file recovery.

Developing projects using Java

Many developers worldwide use Java language for their projects. The Java programming language provides platform independed development, allowing to execute your java project on Windows, Mac OS, Linux, and other operating systems. Because of its flexibility Java programming becoming more and more popular between developers over the world. The concept of "Write once", then "run anywhere" is one of the important feature of java language, making java the most powerful language.

Java has various features that makes it very simple language. Java Programs are easy to write and debug because java does not use the pointers explicitly. It is harder to write the programs that can crash the system. Java language provides the bug free system due to the strong memory management and it has the automatic memory allocation/deallocation system.
