  6. 6. Number of 9's Availability Percentage Total Annual Downtime 2 99% 3 days, 15 hours 3 99.9% 8 hours, 45 minutes 4 99.99% 52 minutes, 34 seconds 5 99.999% 5 minutes, 15 seconds For a given software application or service, high availability is ultimately measured in terms of the end user’s experience and expectations. The tangible and perceived business impact of downtime may be expressed in terms of information loss, property damage, decreased productivity, opportunity costs, contractual damages, or the loss of goodwill. The principal goal of a high availability solution is to minimize or mitigate the impact of downtime. A sound strategy for this optimally balances business processes and Service Level Agreements (SLAs) with technical capabilities and infrastructure costs. A platform is considered highly available per the agreement and expectations of customers and stakeholders. The availability of a system can be expressed as this calculation: Actual uptime/Expected uptime X 100% The resulting value is often expressed by industry in terms of the number of 9’s that the solution provides; meant to convey an annual number of minutes of possible uptime, or conversely, minutes of downtime. http://technet.microsoft.com/en-us/library/jj715263.aspx

  12. 12. All servers that belong to a server farm, including database servers, must physically reside in the same datacenter. Redundancy and failover between closely located data centers that are configured as a single farm ("stretched farm”) is not supported in SharePoint 2013. http://technet.microsoft.com/en-us/library/cc262485.aspx
