Sun Tuesday unveiled the Solaris Dynamic File System, new file system technology that is part of the next rev of its Solaris 10 operating system.

The Solaris Dynamic File System is the latest component to be made available for download through the Software Express program. The main benefit of Dynamic File System is that it enables admins to automate many common tasks.

Sun describes Dynamic File System as a self-healing, self-managing operating system file system technology designed to provide 16 billion billion times more capacity than current file systems while offering virtually unlimited scalability. To do this, Dynamic File System constantly reads and checks data to ensure it is correct. If it detects an error in a mirrored pool, the technology can repair the corrupt data.

Solaris' Dynamic File System is built on top of shared virtual storage pools to simplify the creation and deletion of file systems. This architecture also simplifies administration, enables resources to be shared among file systems, and offers increased storage utilization.

By automating a number of common admin tasks, Sun claims Dynamic File System reduces the process of creating and growing filesystems from 28 separate tasks to five. Translated into time, Sun says it now takes 10 seconds to add mirrored file systems for three users and then add more disk space. Previously this took 40 minutes.

In addition, with Dynamic File System, Solaris 10 is the only known operating system to provide end-to-end check summing for all data, helping reduce the risk of data corruption and loss.

Like Solaris 10, Dynamic File System will be available for industry standard and SPARC Systems. It is also being written for 64-bit architectures, specifically for 64-bit SPARC kernels, scalable Xeon processors, and Opteron processors, Graham Lovell, director of OS marketing at Sun, told ServerWatch.

Other new features in Solaris 10 released through Software Express earlier this year are:

  • Predictive Self Healing, which anticipates an outage and takes a corrective action
  • N1 Grid Containers, system virtualization technology that supports more than 8,000 software partitions per single instance
  • DTrace, a dynamic tracing framework for administrators, developers, and service personnel
  • Cryptographic Infrastructure, which provides cryptographic services to users and applications
  • Process Rights Management, which allows administrators to give users privileges for a specific task, thus eliminating the need for root or super-user privileges, Lovell said
  • IP filter provides network address translation and firewall services

Sun claims an estimated 80,000 users are currently previewing Solaris 10 through Software Express. Since September 2003, more than 16,000 copies of the operating system have been downloaded, Lovell said.

At press time, nearly 30 commercial development partners have begun preparing and testing their applications to support Solaris 10. Vendors include Actuate Corporation, BEA Systems, BMC Software, Check Point Software Technologies, Entrust, Macromedia, RSA Security, SunGard, and Synopsys.

The production ready version of Solaris 10 is scheduled to begin shipping later this year.
