If the service provider is responsible for providing the redundant armature [1], this information must be included in theService LevelAgreement (SLA). The SLA should also include redundancy in case of business interruption or provide some type of compensation.On a larger scale, an organization may also need to have redundant facilities in case a catastrophic event causes damage to the facilities. Redundant facilities are referred to as hotsite(hotsite) > warm site (warmsite), and cold site (coldsite). The price of each type of equipment varies, as does the resulting downtime.For a hotsite, a fully redundant facility requires the use of nearly identical equipment. Replication of data to this redundant facility is part of normal operation.Therefore, in the event of a disaster, the full operation must be recovered by applying only the most recent data changes. Organizations that need to respond in seconds typically deploy global load balancing (GLC).GlobalLoadBalancing (GLB) and distributed SANs are often deployed for rapid response. When such redundancy is deployed, an organization canrecover quickly from an outage or even the destruction of equipment.The warm site is a physically redundant facility, but the software and data are not stored and updated on the equipment. A disaster recovery team is required to run to the redundant facility (whereIt is dependent on the amount of software and data involved and can take several days to get the business back up and running.
