Lotus Notes’ RAID technology is used to safeguard data from being destroyed in the event of a disk failure. It blends multiple hard disk drives into one file system and makes use of fail-tolerance to rebuild information in the event of a single drive failing. This technology is ideal for companies who want to ensure that their data is always accessible.
A raid on the lotus notes iDataAgent Catalog retrieves a database’s transaction log, and then associates it to a specific Notes Database. The transaction log is broken into scaled-down data files called sign extents. Each one is 64MB in size. Each sign extent includes https://advancedexamples.com/ an entry that identifies the date when the database was initially created and when the Fixup activity performed it prior to.
There are a variety of levels of raid, and each provides an individual level of performance and fault tolerance. RAID 1 is the most common, as it uses mirroring to effectively double the storage capacity of an system. It’s not foolproof. It will take hours for the remaining drives to recover information if the mirror disk fails. RAID 5 is a combination of striping and parity that offers good storage and performance. It requires two additional disks to achieve parity, but provides the best balance between storage and efficiency.
