Product Description
3BSE081637R1 PM866AK02 In addition to redundant processor units, there are several common hardware redundancy techniques:
Redundant power supply: Redundant power supply refers to the use of multiple power supplies in the system to ensure that in the event of a failure of one power supply, another power supply can immediately take over its work, thus ensuring continuous operation of the system.
Redundant storage: Redundant storage refers to the use of multiple storage devices in a system to ensure that in the event of a failure of one storage device, another storage device can immediately take over its work, thus ensuring data integrity and availability.
3BSE081637R1 PM866AK02 Redundant network: Redundant network refers to the use of multiple network interface cards (nics) or network paths in a system to ensure that if one network interface card or network path fails, another network interface card or network path can immediately take over its work, thus ensuring the network connectivity of the system.
Redundant fans: Redundant fans refer to the use of multiple fans in a system to ensure that if one fan fails, another fan can immediately take over its work, thus ensuring the heat dissipation of the system.
Redundant Array of Disks (RAID) : RAID is a technology that combines multiple disks together to improve data storage reliability and performance. RAID can provide data redundancy and fault tolerance to ensure that if one disk fails, data can still be recovered through other disks.
These hardware redundancy technologies can effectively improve the reliability and availability of the system, reduce the risk of single point of failure, and thus ensure the continuous operation of the system.
