Rack In Networking

 

Types of Network Racks and Their Specifications

1.     Open Frame Racks

o    What it is: A simple, open structure with no doors or sides.

o    Best For: Easy access to equipment and cables.

o    Specifications:

§  Height: 2-post or 4-post (in U units like 42U).

§  Width: Standard 19 inches.

§  No cooling or security features.

2.     Wall-Mount Racks

o    What it is: Small racks mounted on walls.

o    Best For: Compact spaces or small offices.

o    Specifications:

§  Height: 6U–15U.

§  Depth: 12–18 inches.

§  Lightweight, with basic ventilation.

3.     Server Racks (Enclosed Cabinets)

o    What it is: Fully enclosed with doors and side panels.

o    Best For: High-security and large data centers.

o    Specifications:

§  Height: 42U or more.

§  Depth: 36–48 inches.

§  Features: Cooling systems, locking doors, cable management.

4.     Portable Racks

o    What it is: Movable racks with wheels.

o    Best For: Temporary setups or flexible spaces.

o    Specifications:

§  Height: 12U–24U.

§  Includes: Handles, wheels, and sometimes covers.

5.     Custom Racks

o    What it is: Tailored for specific needs.

o    Best For: Special projects requiring unique dimensions.

o    Specifications:

§  Depends on requirements (height, width, cooling, etc.).

§  Usually more expensive.

                                    ___________________

o    The height of a rack in inches depends on the number of U units it has. Each U (rack unit) equals 1.75 inches.

Example:

§  6U rack: 6×1.75=10.56×1.75=10.5 inches.

§  12U rack: 12×1.75=2112×1.75=21 inches.

§  42U rack: 42×1.75=73.542×1.75=73.5 inches.

So, for any rack height, multiply the U number by 1.75 to get the height in inches!

                               ________________

Common Rack Sizes:

  • 6U Rack:
    • 6 devices (1U each), or 3 devices (2U each).
  • 12U Rack:
    • 12 devices (1U each), or 6 devices (2U each).
  • 42U Rack:
    • 42 devices (1U each), or 21 devices (2U each).

TCP/IP MODEL

  HISTORY OF TCP/IP MODEL THE TCP/IP MODEL WAS DEVELOPED BY VINT CERF AND BOB KAHN IN THE 1970S. THEY WERE BOTH WORKING AT THE DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA) AT THE TIME. Vint Cerf And Bob Kahn CERF AND KAHN WERE TASKED WITH DEVELOPING A NEW NETWORK PROTOCOL THAT WOULD BE MORE RELIABLE AND EFFICIENT THAN THE EXISTING PROTOCOLS. THEY CAME UP WITH THE IDEA OF USING A LAYERED APPROACH, WHICH WOULD ALLOW EACH LAYER TO FOCUS ON A SPECIFIC TASK. THIS LED TO THE DEVELOPMENT OF THE TCP/IP MODEL, WHICH IS STILL THE BASIS FOR HOW DATA IS TRANSMITTED OVER THE INTERNET TODAY. CERF AND KAHN ARE OFTEN REFERRED TO AS THE "FATHERS OF THE INTERNET" FOR THEIR WORK ON THE TCP/IP MODEL. THEY WERE INDUCTED INTO THE NATIONAL INVENTORS HALL OF FAME IN 2004 FOR THEIR CONTRIBUTIONS TO THE DEVELOPMENT OF THE INTERNET. HERE ARE SOME OTHER NOTABLE PEOPLE WHO CONTRIBUTED TO THE DEVELOPMENT OF THE TCP/IP MODEL: JON POSTEL: POSTEL WAS THE FIRST CHAIRMAN OF THE INTERNET ENGINEERI...

Internet Protocol (IP) Address

  IP ADDRESS IT IS A UNIQUE ADDRESS THAT WE CAN ASSIGN TO DEVICE .SO THAT DEVICECAN COMMUNICATE WITH EACH OTHER. WE CANNAOT ASSIGN SAME IP ADDRESS IN ANY TWO DEVICES IN OUR NETWORK. IF WE WILL DO THIS THEN IT WILL BE  CAUSE A CONFLICT ERROR. TWO VERSION OF IP ADDRESS: 1: IPV4 ; 2: IPV6 ; IPV4 32 BITS AND IPV6 128 BITS. AN IP ADDRESS, OR INTERNET PROTOCOL ADDRESS, IS A SERIES OF NUMBERS THAT IDENTIFIES ANY DEVICE ON A NETWORK.  COMPUTERS USE IP ADDRESSES TO COMMUNICATE WITH EACH OTHER BOTH OVER THE INTERNET AS WELL AS ON OTHER NETWORKS. TO FIND THE IP ADDRESS CLASS WE NEED TO LOOK AT THE FIRST DIGIT OF THE IP ADDRESS. AND BY LOOKING AT THE FIRST DIGIT, WE CAN GUESS THE SUBNET MASK TO WHICH CLASS IT BELONGS. CLASS A IP ADDRESS SUBNET MASK 255.0.0.0 CLASS B IP ADDRESS SUBNET MASK  255.255.0.0  CLASS C IP ADDRESS SUBNET MASK 255.255.255.0 IANA TABLE IP RANGES                 IANA   ( Internet Assigned Numbers Au...
