IT and Networking

Application Servers

 

This kind of server is dedicated to running certain software applications. The application server often serves to connect database servers with the end-user, thus acting as a kind of "middleware" that releases stored information requested by said user. The server is usually responsible for properly decoding and recoding data and providing security over connections.

Message Servers

 

Message servers refer to a collection of servers that include chat servers, groupware and IRC servers. These servers provide instant, real-time communication between users, regardless of where a user may be. Message servers allow a wide variety of communication methods, from simple forms such as text to more complex forms such as video, audio and graphics.

 

 

File Servers

 

These servers focus on file management and are responsible for security, management and availability of stored files. These servers allow connections to the end-user for the purpose of sending and receiving files at the request of the user. Servers using a TCP/IP connection usually use the File Transfer Protocol (FTP), while servers on a LAN may use either the SMB/CIFS protocol (Windows and Unix-like) or the NFS protocol (Unix-like systems).

Mail Servers

 

Mail servers provide the services necessary to send, receive and store electronic mail (e-mail), either in a local network, in a wide area network or on the Internet.

 

Proxy Servers

 

This type of server acts as a mediator between a client program and another server to filter requests made by users, improve performance and allow shared connections.

Database Servers

 

These servers manage the database that is stored in that server using the SQL database management system. A client request is sent in the form of an SQL query to the server. That server in turn searches through the database for the requested information and sends the results to the client.

Web Servers

 

Web servers provide access to the Internet through the HyperText Transfer Protocol (HTTP). Files in a web server use HyperText Markup Language (HTML) to display content on web browsers. A web server usually receives requests from a web browser and sends back the requested HTML file and related graphic files.

Servers not listed here generally serve more obscure functions, such as Gopher servers and open source servers. With the advent of online multi-player video games, gaming servers continue to form a growing part of the Internet. Some servers work only on an inter-server level, while technologies for peer-to-peer file sharing, VoIP telephony and television programs bypass servers entirely and connect users directly.

 

 

 

 

ENVIROMUX-SEMS-16U:

 

Also known as: Remote Environment Monitoring System, monitor networking closets, server room alert, IP temperature sensor, humidity sensor, computer room humidity probe.

The ENVIROMUX® Server Environment Monitoring System monitors critical environmental conditions, such as temperature, humidity, liquid water presence, power, intrusion, and smoke. When a sensor goes out of range of a configurable threshold, the system will notify you via email, LEDs, alarm beacon, siren, web page, network management (SNMP), voice phone calls (via Automatic Voice Dialer System), and SMS messages (via external GSM). The system includes three internal sensors: temperature, humidity and power. It also supports 16 external configurable sensors and eight digital input sensors.

  • Monitor and manage server room environmental and security conditions over IP.
  • Create alarm signals with customized input parameters.
  • Four output relays for control of external devices.

Supports IP network video cameras for live view of any facility.

Monitor (ping) up to 64 IP network devices.

  • Available sensors include: temperature, humidity, smoke, water, glass break, motion, vibration, 4-20 mA converter, voltage detector, and more.
  • Stores up to 1,000 event and data entries in system data log.
  • Integrates with various Open Source monitoring packages – Nagios and MRTG.
  • Provides power supply for all sensors.
  • Internal battery backup.

 

 

 

 

Sensaphone:

For small businesses, property owners, and more, the ALL NEW Sensaphone 400 offers an easy, inexpensive way to monitor a remote facility. It can be installed in any clean indoor environment to monitor a variety of applications.

The 400 has a built-in ability to monitor for power failures and to listen to the sound of a smoke detector. There are also four external inputs that can be connected to a variety of sensors to monitor temperature, water on the floor, humidity, and much more. One of the four external inputs already comes with a temperature sensor for monitoring temperature where the 400 is installed.

When an alarm is detected, the Sensaphone 400 can notify up to four people by making voice phone calls. It will continue to make phone calls until someone responds to the call. The voice messages can be custom recorded, so you get to describe each alarm message that it speaks in your own voice. The phone interface includes a line seize feature so that extension phones are automatically disconnected when it needs to make an alarm phone call.
