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.

Mobile application development

It is awesome to view how technology and science has altered the way we undertake our daily tasks. Formerly we had to seek assistance of the preset line telephone whenever we desired to get in touch with our friends or relatives or if they desired to get in touch with us. It was not possible for us to get in touch with these folks, while we had been journeying or no preset line phone was available. All this altered with the growth of the cellular phone. The very first mobiles were bulky and could be utilized just for making phone calls and sending sms messages. Issues have changed quite a great deal since then. The current era cellular phones are extremely slim and enable us to take pictures, view video clips, hear songs, browse the net, enjoy games, and much more.

You can avail these features with the help of specific programs inlayed inside the mobile phones or can be downloaded from the net after which installed. These types of programs also can be purchased by the end-user through software stores. Businesses that are into mobile application development earn a handsome amount of money by marketing their application that provides yet another characteristic on mobile phones. The fundamental idea behind developing mobile phone programs is to modify the way in which individuals get in touch with one another or assist them to carry out complicated jobs easily. A large number of mobile phone applications can be obtained on the internet and devoted stores and all of them play a role in one way or the other to enhance the experience of the end user.
