RAID technology for lotus notes assists to protect information from destruction should hard disks fail. It blends multiple drives on hard disks into one file system and utilizes fail-tolerance to restore information in the event of a single drive failure. This kind of technology is a good option for companies that want to ensure that their information continues to be available throughout the day.
A search in the Lotus Notes iDataAgent catalog gathers data from a database’s transaction log and associates it with the specific Notes database. The transaction log is split into smaller data files, known as sign extents. Each is 64MB. Each sign extent has an entry that indicates when the database was created and when the Fixup activity was running prior to it.
There are several levels of raid, and each one offers an individual level of performance and fault tolerance. RAID 1 is most common due to the fact that it uses mirroring to increase the storage capacity. However, it’s not completely foolproof. It can take a long time for the remaining drives to restore the data in the event that the mirror disk fails. RAID 5 is an amalgamation of striping and parity that provides good storage and performance. It requires two additional disks for parity, but provides the most optimal balance between storage and efficiency.
