Question

I have an application due on the following, but I'm not sure how I should go about creating my table. Can someone help construct the table?

Active/active systems represent the cutting edge of highly available architectures. Able to fail over in seconds rather than minutes, hours, or days, they safeguard data with extraordinary reliability. However, active/active architectures are not necessarily the best choice for all information systems—an organization must consider key variables such as cost, maintenance, and staffing when selecting its fault-tolerance requirements.

Throughout this course, you have encountered a number of different system architectures, a few of which are listed below. Each has its own benefits and risks, and each appropriately addresses the needs of different companies.

Tape backup

Asynchronous Replication

Cluster

Active/passive

Active/active

Bunkering

Companies' availability needs fall along a spectrum, due to factors that include personnel and budgetary constraints. Additionally, the degree to which a business relies on an information system and the requirements placed on that system by stakeholders and regulatory agencies often dictate which infrastructure will be required.

Fault tolerance is not a one-size-fits-all solution. Understanding the specific characteristics of different high availability configurations and implementing them aptly represents the first step toward establishing a successful and reliable data infrastructure.

Construct a table that compares the bulleted systems above. Provide the following information for each:

A brief summary of the system itself, including its components, how it responds to failure, and how data may be affected when an outage occurs.

A typical range of values for its reliability parameters: availability, RTO, and RPO.

One type of organization whose data center/information system needs would be fully satisfied by that architecture, and why.

Explanation / Answer

proper storage architecture that provides for scalable systems, integration and management of storage subsystems.

DAS is the most common form of storage used by companies. Most computer storage devices like disk drives or JBODs (Just a Bunch of Disks), tape devices, and RAID systems are directly attached to a client computer. They use various adapters and standardized software protocols like SCSI (Small Computer Systems Interface) and FC (Fiber Channel).

2 Asynchronus Replication- Asynchronus replication, a single master site supporting materialized view replication provides the mechanisms to support potentially hundreds or thousands of materialized view sites.Multimaster replication, also known as peer-to-peer or n-way replication, is comprised of multiple master sites equally participating in an update-anywhere model. Updates made to an individual master site are propagated (sent) to all other participating master sites.

3) Cluster-A cluster comprises two or more nodes that are linked by an interconnect. The interconnect serves as the communication path between the nodes in the cluster.

Node Components-A node has these main components:

central processing unit - The main processing component of a computer that reads from and writes to the computer's main memory.
memory - The component used for programmatic execution and the buffering of data.
interconnect - The communication link between the nodes.
storage - A device that stores data. This is usually persistent storage that must be accessed by read/write transactions to alter its contents.

4) Active/ passive- Network Switches are the basic components of an IP Network. All the network endpoints (like PC’s, Laptops, Printers, etc) connect to these switches. As the name goes, they switch (distribute) the data received from one node to any other node in the network.
