NAS using the traditional Ethernet and TCP / IP protocol, as for file sharing, then the use of NFS and CIFS to communicate with NT and UNIX systems. As NFS and CIFS are based on the operating system file sharing protocol, so the performance of NAS is characterized by small-file-level shared access.
With the construction of the campus computer network, spread and application, many applications continue to demonstrate the problem is the following directions:
The overall amount of data and reason for a lot of obsolete data storage management is difficult
The segment leading multi-platform and heterogeneous data sharing and management difficult
Data support the rapid growth and concurrent lead to real-time data storage of the load and poor
The popularity of multimedia educational network storage of data put forward higher requirements
These issues in Leshan Teachers College campus network mainly in:
1. In the College strongly universal premise of modern educational technology, professional teachers assisted instruction on the use of multimedia means enthusiasm, the College has more than 30 multi-media teachers to provide teaching services for the whole hospital. But the rich multimedia courses must involve a large number of graphics, images and audio and video data. And the growing amount of data, which determines the original server's storage capacity is not enough.
2. As a public platform for multimedia teacher. If you are bringing a large number of teachers per class electronic teaching materials, will result in excellent original facilitate modern teaching methods, but the way in achieving the inconvenience. Hence the urgent need of public and secure data exchange and sharing platform. Requires not only high-capacity storage devices, and require very secure data storage.
3. With the construction of the campus network for many years, has accumulated a large amount of important information and data, completed construction of a number of important software systems, data and application of these much-needed backup support.
4. Institute for each teacher create a personal home page, used to publish relevant information and teaching materials, need easy to use and high performance FTP server.
5. Other applications, such as people over the size of the student mail system, campus VOD video on demand system, campus software distribution and installation within the public service are required to solve a lot of storage space.
Summary, Leshan Teachers College network storage needs:
1. Need high capacity network storage, storage, teaching and research large amount of data generated in the process;
2. Requirements can be multi-user, multi-platform of data and have enough to enjoy the security management model.
3. Requires the ability to centrally manage data and improve data protection.
4. Reducing management costs and maintenance costs and the use of a good memory scalability. The main features
NAS
NAS using the traditional Ethernet and TCP / IP protocol, when file sharing, then the use of NFS and CIFS to communicate with NT and UNIX systems. As NFS and CIFS are based on the operating system file sharing protocol, so the performance of NAS is characterized by small-file-level shared access. From the simple mechanism can be seen NAS, NAS deployment is very simple, you can only connect with the traditional switch; Second, it costs less, because the investment is limited to NAS a NAS server, rather than the entire SAN storage network at the same time, NAS server prices are often targeted for SMEs; third, NAS server management is very simple, it is general support for Web client management, network management personnel are familiar with the operating system, its set to both familiar and easy.
