RAID technology is an amazing feature of Lotus Notes. It protects information in the event of a failure of the hard drive. It integrates multiple hard disk drives into one file system, and employs fail-tolerance in the event of a single drive failing. It’s especially beneficial for businesses that have multiple hard drives and need to ensure their information is always accessible.

A typical raid setup consists of three or two hard disks. Each disk has its data path. It also has a transaction record which is typically divided into smaller, scaled-down files referred to as log extents. The log extents are typically 64MB in size. The transaction log is supervised by the Notes Machine.

Raid has been around for decades and is a crucial component of the majority of datacenter systems. However, it’s far from foolproof. The entire file system could be rendered unusable if more than one drive fails.

Despite its shortcomings, raid is still used by some organizations to safeguard their critical data. The most recent versions of RAID and other features, such as erasure codification, are more efficient than ever in protecting data from damage and offer more performance. However, they are more than traditional raid solutions.
