RAID technology for lotus notepads helps 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 restore information in the event of a single drive failing. This technology is perfect for businesses who need to ensure that their data is always available.
A search for Lotus Notes in the iDataAgent catalog locates the transaction log of a database, and associates it with a specific Notes database. The transaction log is divided into smaller data files called sign extents. Each is 64MB. Each sign extent contains an entry that indicates when the database was created and also the date it was run by the Fixup program.
There are different levels of raid. Each level offers different level of performance and failure tolerance. RAID 1 is most common since it makes use of mirroring to double the storage capacity. It’s not completely secure. It can take several hours for the remaining drives to recover information if the mirror disk fails. RAID 5 is an amalgamation of striping and parity that gives you good storage and performance. It requires two additional disks for parity but offers the best balance between storage capacity and efficiency.
