Hi friends, let’s talk this time about the new concept in file manager that will be introduced by Microsoft in its new Operating system Windows Vista. The name of this new file administration is “WinFS”.
WinFS is a new file system that it’s being developed by Microsoft to be used in its new operating system Windows Vista. At the begining this name means Windows Future Storage, but now is only Windows File System. Acctually, there is no clear information about what “WinFS” is. Some people say that is a complete new file system and others say that WinFS is only an extension of the actual system because many of the file system work is done by NTFS.
Necessity
With the evolution of Internet and the information technologies, working with big volumes of information has increasingly become more common. Hard disks represent the first half of the storage for personal information. They are commonly used to store personal contacts, work documents, etc. These information items usually keep certain relationship levels among them. So, when you work with a large number of these items, it is very important to organize them and provide a flexible search mechanism based on their properties and content.
Architecture
WinFS is a storage platform to organize, search and share a wide diversity of information.
Instead of a traditional tree in NTFS to organize information, WinFS uses a direct acyclic graph of items (DAG). It is a set of stored items and their relationships whose physical storage is a relational database providing support to store any item hierarchy. Now it is possible to find items according to the value of their properties and even to the value of the properties of items related to them.The data-sharing capacities of WinFS come with a set of services such us synchronization, notification, a unified store and a common security model. The integration of these services to other technologies like Active Directory makes it possible for applications to share data in a flexible way.
Conclusions
WinFS data model expresses a set of modern storage concepts featuring a combination of the file system services and the relational system to provide a new powerful and enhancing storage platform. This actually elevates the file system conception to a higher level. The WinFS Item may be expressed in XML, object-oriented or tabular manner which allows the WinFS functionalities to be used in a variety of heterogeneous environments. In addition to this, WinFS features a powerful API to develop applications that use its potentialities. Due to its conception WinFS data model represents a step forward in the evolution of file systems and even of storage platforms.

Cisco's Catalyst 6500 Remains The Network Switch To Beat
San Francisco, California October 10, 2006: Following a lackluster Q3, Cisco Systems emerges as the leader in the 10 Gigabit Ethernet Switch Market for the fourth quarter. Fueled by increased demand and an overall rise in the average selling price, Cisco experienced significant gains in a market of over $300 Million.
With almost 70% of the projected $1.3 Billion 10-Gig market share and a more powerful, yet affordable design, the Catalyst 6500 is poised to cement Cisco as the dominating force in the industry. With the recent release of an eight-port, 10-Gigabit Ethernet module for the 6500, Cisco is quickly pulling away from the rest of the pack.
In addition, upgrades like the Application Control Engine (ACE) module have prompted companies like Pure Video Networks to adopt Cisco switches to manage traffic of their popular video websites. Implementing simultaneous data center services such as server load balancing, integrated network and application switching/security, the ACE module delivers the highest performance in the industry. The ACE Simplifies application infrastructure by combining the functionality of multiple application delivery appliances into a single module, including server load balancing and off-load, Secure Socket Layer (SSL) protocol, security, and application optimization capabilities.
Already the most successful networking switch on the IT market, the 6500 Series reduces existing operational costs and improves a network's ability to respond to intensive bandwidth demands. In general, customers using the services modules for the Catalyst 6500 reduce their total cost of ownership by taking advantage of simplified infrastructure, improved investment protection, pervasive security, and the high levels of performance, scalability, and innovative technologies.
With over twenty unique service modules in five distinct categories, the Catalyst 6500 ranks among the most scalable, high-performance platform for integrated services. Currently, Cisco offers modules that address security issues, application, networking, network monitoring, wireless/mobility, and IP communications, which can be integrated into existing catalyst switches. Each modules offers upgraded performance and reinforces Cisco's hold on the market for network switches. With more than $20 Billion is sales sine it's release in 1999, the 6500 Series switch has become the most popular networking platform ever.
While Cisco has been able to fend off most threats to their position, rival Foundry Networks, and newcomer Force 10 have recently launched new 10Gbe ready products aimed at disrupting the company's market share. According to literature on Force 10's Terascale E-Series 1200, the E1200 boasts of more than double the ports of the Catalyst 6500 (1260 vs. 576 Ethernet ports/chassis). While this may be good news for the company, Force 10 has been focused on the data center vertical, and is therefore still untested in the enterprise market. Foundry's BigIron RX series switch has received favorable press for it's size/performance ratio and lower prices. With the launch of the new RX series, Foundry has mounted a consistent affront to Cisco's unchallenged reign.
Even with the competition mounting new efforts, the Cisco name is still a major factor among IT professionals whose networks depend on their equipment. Fortunately for the stalwart Cisco, reputation is still the key to market dominance.
