Dell High Availability and Disaster Recovery Solutions Using Microsoft SQL Server 2012 AlwaysOn Availability Groups discuss various server and storage options available from Del that are most conducive to optimal AVG deployments. Objectives  Understanding how AlwaysOn Availability Groups may be the right choice for implementing High Availability and Disaster Recovery solutions for business critical SQL databases based on customer RTO and RPO requirements.  Exploring the various hardware combinations possible using the latest Dell PowerEdge servers and available internal/external database storage options for HA and DR implementations.  Defining useful HA and DR implementation scenarios with AlwaysOn Availability Groups.  Discussing guidelines and recommendations for implementing AlwaysOn Availability Groups. Why Dell server and storage hardware for AlwaysOn setup? Dell recently launched its 12th Generation PowerEdge servers which bring to the market many new features and enhancements that benefit the AlwaysOn Availability Group deployments. These features and enhancements are detailed below. Processors By supporting Intel® E5-series processors, Dell's 12th Generation PowerEdge servers provide the heavyduty computing power required by high performing AVG databases. Together with High Quick Path Interconnect (QPI) links, 20MB L3 cache, and support for many 3rd Gen PCIe slots, this makes the Dell 12th generation PowerEdge servers the right platform for hosting high performing AVG databases. Memory AVG deployments benefit from the high speed memory DIMMs. Dell's 12th Generation PowerEdge servers support 1333 and 1600 MHz high speed memory DIMMS with ECC. Single, Dual and Quad rank DIMMs are supported. With the high speed memory DIMMS, Dell's solutions can achieve noticeable improvement in the overall database throughput. Internal storage (HDD and SSD) Dell's 12th Generation PowerEdge rack servers have a flexible storage chassis that supports 2.5- and 3.5-inch SAS HDDs and PCIe-based SSD drives with various capacities and speeds. This flexibility allows customers to choose drive type and number of drives based on their application requirements. For example, the PowerEdge R720xd can handle the storage-intensive databases needs of the entrylevel customer without demanding external storage. It supports 24 front-accessible 2.5-inch SAS drives, and provides a single server and storage platform for deploying AlwaysOn AVG databases. The Dell PowerEdge R720/R820 supports up to 4 front loading 2.5-inch PCIe SSD drives. This innovative server architecture allows the deployment of high performing AVG databases on PCIe SSD drives of the server, and achieves better throughputs and failover/failback times at lower latencies. 5
