RAID technology for lotus notes assists to protect information from destruction if hard disks fail. It blends multiple hard disk drives into one file system, and makes use of fail-tolerance to rebuild data if a single drive fails. This kind of technology is a great choice for businesses that need to ensure that their data remains accessible throughout the day.
A search in the lotus notes iDataAgent Catalog retrieves a database’s transaction log, and then associates it to a specific Notes Database. The transaction log is split into smaller data files, referred to as sign extents, each one 64MB in size. Each sign extent includes a record indicating when the database was first created and the date that the Fixup activity performed it prior to it.
There are different levels of raid. Each one offers a different level of performance and fault tolerance. RAID 1 is the most common, as it uses mirroring to basically double the storage capacity of the system. However, it’s not 100% secure. If the failed mirrored disk is damaged it could take a long time to recover data from the remaining drives. RAID 5 is another option that combines striping with parity to secure your lotus notes give you good storage and performance. It requires two extra disks for parity but it offers the greatest combination of storage and efficiency.
