Raid technology for lotus notes is an element that allows designers to develop high-performance work applications. It makes use of open standard devices such as JavaScript and WEB CODING to make it easier for designers to create sophisticated work applications in a short time. It also provides a more stable environment for directories and data files.
Lotus Notes’ RAID technology helps protect data from being destroyed in the event of a disk failure. It blends multiple hard disk drives to create one file system and makes use of fail-tolerance to rebuild information if a single drive fails. This type of technology is a good choice for companies who need to ensure that their data is available all the time.
A raid for lotus notes iDataAgent catalog locates the transaction log for a database and associates it with a specific Notes database. The transaction log is split into smaller data files known as sign extents. Each sign extent is 64MB. Each sign extent has an entry that identifies when the database was first created and when the Fixup activity ran it previously.
There are a variety of levels of raid, each offering a different level of performance and fault tolerance. RAID 1 is the most common, as it uses mirroring to effectively double the storage capacity of the system. It’s not 100% reliable. If the mirrored disk fails it could take a long time to recover data from remaining drives. RAID 5 is another option that combines striping with parity to provide good storage and performance. It requires two extra disks for parity, however it offers the greatest combination of efficiency and storage.
