RAID technology for lotus notes helps to protect information from destruction in the event that hard disks fail. It connects multiple hard disk drives to form one file system and employs fail-tolerance to restore information in the event that a single drive fails. This technology is perfect for companies that need to ensure that their information is always accessible.
A search in the Lotus Notes iDataAgent catalog retrieves a database’s transaction log and connects it to a specific Notes database. The transaction log is divided into smaller data files known as sign extents, each one 64MB in size. Each sign extent has the date that shows the date of creation of the database and the date it was last executed by the Fixup activity.
There are several levels of raid, and each one offers various levels of performance and fault tolerance. RAID 1 is most common since it makes use of mirroring to double the storage capacity. It’s not foolproof. If the mirroring disk fails it can take hours to recover data from the remaining drives. RAID 5 is a different option that combines striping with parity to give you good storage and performance. It requires two extra disks for parity, but it offers the best combination of storage and efficiency.
