RAID technology is an amazing feature of Lotus Notes that protects information in the event of a failure of the hard drive. It blends several hard disk drives into a single file system, and uses fail-tolerance in the case of the failure of a single drive. It’s particularly useful for companies who have multiple hard drives and need to ensure that their info is always accessible.
A typical setup for raids consists of two or more hard disks and each disk has its own data path. It also has a transaction log, which is usually divided into smaller, scaled-down files referred to as log extents. The log extents are typically 64MB in size. The transaction log is controlled by the Notes Machine.
Raid is a popular form of storage that’s been in use for a long time, and is an integral part of many datacenter systems. But it’s not completely reliable. The entire file system can be rendered unusable if more than one drive fails.
Despite its shortcomings it is still employed by some companies to safeguard their important data. The latest versions of RAID, such as erasure codes, are more effective than ever in protecting data from loss and provide higher performance. However, they are more than traditional raid solutions.
