SQL Server 2012 New Feature Overview# Copyright 2012 EMC Corporation. All rights reserved.This slide details all of SQL Server 2012S new features.

The feature we are showcasing in this presentation is SQL Server 2012 AlwaysOn Availability Groups. Microsoft has provided critical enhancements to High Availability with the introduction of new AlwaysOn features, particularily AlwaysOn Availabiliy Groups which provide the next evolution for SQL Server transactional replication.

#EMC Multisite Disaster Recovery For Microsoft SQL Server 2012EMC VNX5700, EMC FAST Cache, SQL Server AlwaysOn Availability GroupsSQL Server AlwaysOn

# Copyright 2012 EMC Corporation. All rights reserved.SQL Server offers administrators several options to configure high availability for both servers and databases. These high availability configurations have until now included:Database mirroringANDLog shipping

SQL Server 2012 introduces two high availability configurations as part of SQL Server AlwaysOn, which provides availability at either the application database or instance level:

AlwaysOn Failover Clusteringfor instance level protectionAND AlwaysOn Availability Groupsfor database level protection#EMC Multisite Disaster Recovery For Microsoft SQL Server 2012EMC VNX5700, EMC FAST Cache, SQL Server AlwaysOn Availability GroupsSQL Server High Availability FeaturesHA LevelBefore SQL Server 2012SQL Server 2012Instance SQL Failover Cluster AlwaysOn Failover ClusterDatabase Backup and Restore Log Shipping Transactional Replication SQL Snapshot SQL Mirroring+ AlwaysOn Availability Group# Copyright 2012 EMC Corporation. All rights reserved.As stated: SQL Server High Availability and Disaster Recovery can be implemented at SQL Server database level or SQL Server instance level.

A database-level High Availability and Disaster Recovery feature provides more flexibility in managing which databases should, or should not, be moved to the secondary server. AlwaysOn Availability Group is an example of a database-level solution.

SQL Server 2012 AlwaysOn Failover Cluster is an example of a SQL Server instance level solution.

Before SQL Server 2012, having too many HA features in SQL Server could be confusing to customers. You may wonder which solution is better for your application and what are the pros and cons for each HA solution. With AlwayON microsoft has evolved its HA features, simplifying the choice for customers . For database level protection microsoft recommends the use of Avaialabilty Groups over traditional Log Shipping and Database mirroring.#EMC Multisite Disaster Recovery For Microsoft SQL Server 2012EMC VNX5700, EMC FAST Cache, SQL Server AlwaysOn Availability GroupsAlwaysOn Failover Cluster

Multi-subnet support now available# Copyright 2012 EMC Corporation. All rights reserved.With the AlwaysON Failover Cluster a single SQL Server instance is installed across multiple Windows Server Failover Cluster nodes. WSFC functionality provides high availability at the instance level, by presenting a failover cluster instance to the network as a single computer accessible through the clusters virtual name. This configuration is an enhancement to the SQL Server FCI functionality available in previous versions of SQL Server.

It is very much like todays FCI but more resilient in terms of varying networks.

Our current testing involves using ALWAYSON FCI with Recoverpoint and Cluster enabler.#EMC Multisite Disaster Recovery For Microsoft SQL Server 2012EMC VNX5700, EMC FAST Cache, SQL Server AlwaysOn Availability GroupsNotes second bullet, each hosting databases that could be configured as readable.

All rights reserved.Significant improvements have been delivered to the multisite failover clustering technology making it a viable option for HADR for many use cases and specifically multi-subnet failover clustering implementation.

Two major enhancements which support multi-subnet clustering are:

1. Cluster Setup supportcan intelligently detect a multi-subnet environment, and automatically set the IP address resource dependency to OR. as shown in the slide

2. SQL Server Engine supportTo bring the SQL Server resource online, the SQL Server Engine startup logic skips binding to any IP address that is not in an online state.#EMC Multisite Disaster Recovery For Microsoft SQL Server 2012EMC VNX5700, EMC FAST Cache, SQL Server AlwaysOn Availability GroupsAlwaysOn Availability Groups

AlwaysOn Availability Groups support a failover environment for a specific set of user databases, known as availability databases, these databases failover together.

Like AlwaysOn Failover Clustering, AlwaysOn Availability Groups require the SQL Server instances to be configured on nodes of the same cluster, but with the instances remaining and being presented to the network as separate computers.

Availability groups support a set of primary databases and one to four sets of corresponding secondary databases. An availability group fails over at the level of an availability replica and, optionally, secondary databases can be made available for read-only access and some backup operations.

Availability groups consist of a set of two or more failover partners referred to as availability replicas. Each availability replica is hosted on a separate instance of SQL Server

Each availability replica hosts a copy of the availability databases in the availability group. Each availability replica is assigned an initial role as either the primary role or the secondary role#EMC Multisite Disaster Recovery For Microsoft SQL Server 2012EMC VNX5700, EMC FAST Cache, SQL Server AlwaysOn Availability GroupsNotes second bullet, each hosting databases that could be configured as readable.
