RAID technology for lotus notes can help to safeguard information from destruction should hard disks fail. It blends multiple drives on hard disks into one file system and makes use of failure tolerance to rebuild data in the event of a single drive failure. This kind of technology is an excellent option for businesses who want to ensure that their data is available all the time.
A search in the Lotus Notes iDataAgent catalog gathers data from the transaction log of a database, and associates it with a specific Notes database. The transaction log is divided into smaller data files known as sign extents. Each sign extent is 64MB. Each sign extent has an entry that indicates when the database was first established and when the Fixup activity ran it before.
There are different levels of raid. Each level offers different level of performance and the ability to tolerate faults. RAID 1 is the most frequent, since it makes use of mirroring to effectively double the storage capacity of the system. But it's not foolproof. It can take a long time for the remaining drives to recover the data if the mirror disk fails. RAID 5 is an amalgamation of striping and parity that offers good storage and performance. It requires two extra disks to parity, but it is the most efficient combination of storage and efficiency.
