peilattu

Peilattu is a Finnish term that translates to "mirrored" or "reflected" in English. It is primarily used in a technical context, particularly in computing and network administration.

In computing, peilattu refers to a process of data replication where identical copies of data are maintained on two or more storage devices. This is often done for redundancy and fault tolerance. If one device fails, the data can still be accessed from the other mirrored device, preventing data loss and minimizing downtime. This technique is commonly employed in RAID configurations (Redundant Array of Independent Disks), specifically RAID 1, which is often referred to as mirroring.

In networking, peilattu can also describe the replication of server configurations or services across multiple machines. This ensures high availability and load balancing. For example, web servers can be mirrored so that if one server becomes overloaded or fails, traffic can be seamlessly redirected to the other mirrored servers.

The concept of peilattu emphasizes the creation of exact duplicates to ensure that data or functionality is always accessible, even in the event of hardware failure or high demand. It is a fundamental principle for building robust and reliable systems.
