What types of disk arrays provide the MOST fault tolerance?

RAID 6 provides the most fault tolerance of any standard RAID disk arrays (RAID 0, 1 , 5, 6, and RAID 10). If any two disks in a RAID 6 array fail and are removed, then two new blank disks can be installed and no data has been lost. RAID 1+1 or most other "layered" RAID systems can provide more fault tolerance than RAID 6, tolerating the failure of any 3 disks. Some experimental non-standard disk arrays can provide more fault tolerance with less overhead, such as the parchive system. Nearly all distributed file systems and distributed version control systems can be set up so that if one machine is completely destroyed by fire, all the data can be recovered from a backup machine in another building.

What is the most common topology and technology combination in use today?

The most common topology in use today is the star topology, primarily due to its scalability and ease of management. This topology often utilizes Ethernet technology, particularly with twisted-pair cabling, which is prevalent in local area networks (LANs). The star topology allows for easy addition and removal of devices without disrupting the network, making it ideal for modern networking needs. Additionally, advancements in wireless technology have also popularized star topology in Wi-Fi networks.


Difference between temporal redundancy and spatial redundancy?

The redundancy is nothing but the reduction.The temporal locality is of relating to short time requirements.And the spatial is of relating to over environment.The redundancy occur in the images are of most common,so many techniques applied to overcome this. In image temporal redundancy is of abrupt transitions while in spatial it is of block based transitions.Spatial is applied at minimum cost and temporal is at maximum cost.Threshold values apply to temporal redundancy and the pixel comparison technique applies to spatial redundancy.


Why was fault tolerance a major focus of the initial design for the internet?

Fault tolerance was a major focus of the intitial design of the Internet because the serial data connections that formed the backbone of the Internet were noisy and subject to bit errors, both single and burst, because they often used telephone lines, and various techniques were developed to detect/retransmit or detect/correct errors. Data integrity was and is paramount, and most protection is provided at layer four (transport layer), although much work has been done recently to enhance layer 2 (network layer) and layer 1 (physical layer).

What is the most fault tolerant physical topology?

Mesh type of topology is the most reliable.


What network topologies are most commonly used on today's networks?

star topology. Because they include a centralized connection point; can easily be moved, isolated, or interconnected with other networks; they are, therefore, scalable. For this reason, and because of their fault tolerance, the star topology has become the most popular layout used in contemporary LANs.


Why would you use a hybrid topology?

Reliable because a hybrid topology can diagnose and isolate faults efficiently. A network fault (such as a faulty node or a break in a network cable) will not affect the performance of the rest of the network. A hybrid network quickly scans all nodes and hardware points to detect where a fault lies, isolates it, and carries out further diagnostic tests. The rest of the network remains fully functional while this fault isolation and diagnosis is carried out. Flexible because I combine various configurations to bring about most optimal conditions to suit network traffic, processing loads and data latency. Hybrid networks can be expanded easily to add new systems and nodes. Each concentration point (or the point which a network connection is made) is designed to hold extra lobes. Additional network hardware peripherals can be attached to these lobes in order to increase capacity.A hybrid topology is able to tap into the strengths of other topologies and ignore their weaknesses. This results in a complex network that is more efficient and effective than individual topologies. It combines the optimal features of its combined topologies. For instance, a star-wired ring topology combines the features of a star topology with those of a ring topology. This hybrid topology combines the fault tolerance capability of the star topology with the data reliability of the ring topology. A star-wired bus topology combines the features of a star topology with a linear bus topology. It combines the network extension features of the bus topology with the simplicity and fault tolerance of the star topology.


What are the disadvantages of mesh topology?

There are several advantages to a mesh network topology. First, it is fault tolerant; since there is no gateway, nodes can connect to each other with no regard to the state of the rest of the network. In addition, nodes can create their own paths through the network because there is no gateway computer. One disadvantage to a mesh topology is that setup time can be quite time consuming.

Is there any fault tolerance such as raid built into anetwork attached storage device?

Many Network Attached Storage (NAS) devices do include built-in fault tolerance features, with RAID (Redundant Array of Independent Disks) being one of the most common implementations. RAID allows data to be distributed across multiple drives, providing redundancy in case of drive failure. Depending on the RAID level configured (such as RAID 1, 5, or 6), NAS devices can offer varying degrees of fault tolerance and performance benefits. It's important to choose the appropriate RAID level based on your specific data protection and performance needs.


What is the most popular Ethernet topology?

The "star" topology is the most common.


What is types of RAID?

RAID, or Redundant Array of Independent Disks, comes in several levels, each designed for different needs. The most common types include RAID 0 (striping for performance without redundancy), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for a balance of performance and fault tolerance), and RAID 10 (a combination of striping and mirroring for both speed and redundancy). Other variations, like RAID 2, 3, 4, and 6, exist but are less commonly used. Each RAID level offers distinct advantages and trade-offs depending on the requirements for performance, redundancy, and storage capacity.


Which topology would be the most redundant?

mesh topology


What is the most reliable network topology?

The most reliable network topology is often considered to be the mesh topology. In a mesh network, each device is connected to multiple other devices, providing multiple pathways for data to travel. This redundancy ensures that if one connection fails, data can still be routed through alternate paths, minimizing downtime and enhancing reliability. However, mesh networks can be more complex and costly to implement compared to simpler topologies.


Which topology is the most commonly used server network topology?

The most common LAN topology is that of a "star." In a star topology, each computer, or "node", is connected to a central hub. This is more reliable than a more classical "ring" topology, because a node failing will not bring down the entire network. A bus topology is arguably more reliable, but has poorer performance.
