RAID technology for lotus notes helps to safeguard information from destruction should hard disks fail. It blends multiple hard disk drives into one file system. It also makes use of fail-tolerance in order to rebuild information in the event of a single drive failure. This type of technology is a good choice for businesses that need to ensure that their information continues to be available throughout the day.
A search of the Lotus Notes iDataAgent catalog gathers data from the transaction log of a database and connects it to the specific Notes database. The transaction log is broken into smaller data files, called sign extents, each 64MB in size. Each sign extent contains a record indicating the date when the database was initially created and the date that the Fixup process was run prior to it.
There are different levels of raid. Each has different level of performance and fault tolerance. RAID 1 is most common because it utilizes mirroring to double the storage capacity. It’s not 100% reliable. If the failed disk is mirrored it can take hours to recover data from remaining drives. RAID 5 is another option that combines striping and parity to provide good storage and performance. It requires two additional disks to achieve parity, but it provides the most optimal balance between storage and efficiency.
