The Raid Technology for Lotus Notes is a feature which allows designers to create high-performance 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 within a short time. It also provides a stable environment for directories, data files and other types of data.
Lotus Notes’ RAID technology is used to safeguard data from being destroyed in the event of a hard disk failure. It blends multiple hard disk drives into one file system and uses fail-tolerance in order to rebuild information if single drive fails. This is a great option for companies who want to make sure that their data is always accessible.
A search in the Lotus Notes iDataAgent catalog gathers data from the transaction log for a database and connects it to a specific Notes database. The transaction log is broken into smaller data files known as sign extents, each 64MB in size. Each sign extent contains the date that shows when the database was created and also the date it was executed by the Fixup activity.
There are different levels of raid. Each offers different performance and the ability to tolerate faults. RAID 1 is most common because it utilizes mirroring to double the storage capacity. It’s not completely secure. If the failed mirrored disk is damaged it can take hours to restore data from the remaining drives. RAID 5 is a different option that combines striping and parity to provide good storage and performance. It requires two additional disks for parity but offers the best balance between storage capacity and efficiency.
