Oracle Solaris ZFS

Integrated Cloud, Applications and Platform Service

Oracle Solaris 11 delivers many path breaking innvovations in Operating System technology for you to build, deploy and manage many complex, mission critical, uninterruptable enterprise services.

Oracle Solaris ZFS offers dramatic advancement in data management, an innovative approach to data integrity, near-zero administration, and a welcome integration of file system and volume management capabilities. The centerpiece of the new architecture is the concept of a virtual storage pool, which decouples the file system from physical storage, allowing much more-efficient use of storage devices.

KEY FEATURES :-

  1. Rock-solid data integrity: Data protected by 256-bit checksum, data consistency maintained at all times 
  2. No silent data corruption ever: ZFS self-healing feature automatically repairs corrupt data
  3. Mind-boggling scalability: 128-bit file system, zillion times the capacity of 32- or 64-bit file systems
  4. Breathtaking speed: Proven, cutting-edge technologies combined to optimize performance
  5. Near-zero administration: Complicated storage administration is automatic and simplified

My Presentation Oracle Solaris ZFS. Try it out. Simple and easy to follow steps.

Solaris DTrace, An Introduction

As a lead performance engineer with wide exposure to multiple applications in various industry domains, and working on Solaris10 platform for years. I believe, SolarisTM DTrace is one of the coolest innovations that could have ever happened in the Operating System world. DTrace was designed and implemented at Sun Microsystems by Bryan Cantrill, Adam Leventhal and Mike Shapiro.

DTrace is a comprehensive dynamic tracing framework created for troubleshooting kernel and application problems on production systems in real time. DTrace was developed for Solaris and released under the Common Development and Distribution License (CDDL). Other OS communities, after realizing the high potential and worthiness, have initiated projects to make DTrace available on respective operating systems.

DTrace can be used to get a global overview of a running system, such as the amount of memory, CPU time, filesystem and network resources used by the active processes. It can also provide much more fine-grained information, such as a log of the arguments with which a specific function is being called, or a list of the processes accessing a specific file. DTrace is Programmable, Flexible, Robust, Safe and Easy-to-Learn-and-Use. Possibilities are Endless !
