What is data center network topology?
What is data center network topology?
Data center topology refers to the general construction of a data center. The types of layout and related technologies help to address the needs of a data center in handling business intelligence as a central repository.
Which topology is followed to connect servers in a datacenter?
Leaf-spine is a data center network topology that’s catching on for data centers that experience more east-west network traffic. This topology augments the spine-layer with more switches to handle traffic within the data center, such as storage area network data traffic.
What cables do data centers use?
AC/DC power, ground, copper and fiber optic are the main types of network cabling used in data centers. The interface that is available on the equipment used in the data center is the primary means for determining which type of cabling should be used.
What is network topology explain various topologies with diagrams?
Network topology refers to the manner in which the links and nodes of a network are arranged to relate to each other. A network topology diagram helps visualize the communicating devices, which are modeled as nodes, and the connections between the devices, which are modeled as links between the nodes.
Is a data center a LAN?
For many years data center facilities have been served by two distinct networks: the local area network (LAN) and the storage area network (SAN). As with LANs in commercial office-type environments, Ethernet has been the transmission protocol of choice in data center LANs.
How many types of data center topologies are there?
There are three main data center topologies in use today—and each has its advantages and trade-offs. In fact, some larger data centers will often deploy two or even all three of these topologies in the same facility.
Is the aggregation point for devices that provide services to all server farms?
The aggregation layer is the aggregation point for devices that provide services to all server farms. Specific server farms are likely to span multiple access switches for redundancy, thus making the aggregation switches the logical connection point for service devices, instead of the access switches.
What are the topologies of a data center?
Initially, the discussion focuses on the traffic flow through the network infrastructure (on a generic topology) from a logical viewpoint and then from a physical viewpoint. The generic Layer 3/Layer 2 designs are based on the most common ways of deploying server farms.
What kind of topology does a home network use?
Many home networks use star topology. A star network features a central connection point called a “hub” that may be a hub, switch, or router. Devices typically connect to the center with Unshielded Twisted Pair (UTP) Ethernet.
What kind of cabling is used in data centers?
Structured cabling design and installation is governed by a set of standards that specify wiring data centers, offices, and apartment buildings for data or voice communications using various kinds of cable, most commonly category 5e (CAT-5e), category 6 (CAT-6), and fibre optic cabling and modular connectors.
When did Cisco Press Release data center topologies?
Sample Chapter is provided courtesy of Cisco Press . Date: Dec 31, 2003. This sample chapter covers types of server farms and Data Centers, Data Center topologies, fully redundant Layer 2 and Layer 3 designs, and fully redundant Layer 2 and Layer 3 designs with services.
