  1. SQL Server 2014: Overview Phil Brammer @PhilBrammer ssistalk.com

  2. Phil Brammer • Over 13 years’ experience in database technologies, data warehousing, ETL, on-call… • Worked with Teradata at PayPal • Operationally manages multi-terabyte instances • Dabbles a bit in SSIS – ssistalk.com • Microsoft MVP, SQL Server – 7th year

  3. Breakthrough Performance & Scale • In-Memory OLTP (Hekaton) • Columnstore Improvements • Query Performance Improvements • Resource Governor for I/O • Buffer Pool Extension • Scale Optimizations for > 8 socket systems

  4. Enhanced High Availability • AlwaysOn Enhancements • Online Database Operations

  5. Hybrid Scenarios • Smart Backup • AlwaysOn Replica in Windows Azure VM • SQL Server with Azure Storage Integration • On-Prem to Azure Migration

  6. Other • Separation of Duties • Extending PowerView • Windows Server Enhancements

  7. BP & S: In-Memory OLTP • Up to 20-30x throughput • Easy to migrate existing applications • Integrated experience • Full ACID support • All in-memory. No buffer pool, B-Trees • No lock manager, latches, or spinlocks

  8. BP & S: Columnstore • New clustered option • Completely read/writeable • New archive option for even more compression

  9. BP & S: Query Performance Improvements • New cardinality estimator • Incremental statistics per partition

  10. BP & S: Resource Governor • Limit I/O to a Resource Pool • Limit CPU usage; percent, affinity • Limit DOP • Limit Memory

  11. BP & S: Buffer Pool Extension • Ability to extend buffer cache to any volume (SSD) • Improve OLTP performance • No risk of data loss (clean pages) • Easy to implement

  12. HA: AlwaysOn Enhancements • Up to 8 readable secondaries • Ability to use readable secondaries during network failures • Cluster Shared Volume support • Easier troubleshooting • Wizard to add replica to Azure

  13. HA: Online Operations • Single partition online index rebuild • Manage lock priority for SWITCH and online index rebuild operations

  14. Hybrid: Smart Backup • Input storage URL (Azure), retention • Automatically backs up databases • Automatically cleans up • Context aware • Minimal storage costs • Zero hardware management • No media decay

  15. Hybrid: Backup to Azure Storage • Near-bottomless storage • Offsite, geo-redundant • No provisioning • No device management • No media decay • Remote accessibility

  16. Hybrid: AlwaysOn Replica in Azure • Wizard to add a replica in Windows Azure VMs • Eliminates DR site needs (hardware, rent, etc…) • Offload read/backup workloads

  17. Hybrid: SQL & Azure Storage Integration • Native support for SQL Server database files stored as Azure blobs • Can move a single database at a time • Save storage costs • Backed by Azure Storage SLAs • Fast disaster recovery using database attach • Control security with on-prem model

  18. Hybrid: Migrations to Azure VMs • New Wizard to migrate databases to Azure VM • Perfect for DBAs new to Azure • No need of specific Azure knowledge • Time to transfer DB is limiting factor

  19. Other: Separation Of Duties • CONNECT ANY DATABASE • IMPERSONATE ANY LOGIN • SELECT ALL USER SECURABLES • Allows for greater role separations – audit vs admin

  20. Other: Power View for Multidimensional Models • Allows native support for DAX in Analysis Services • via BI Semantic Model

  21. Other: Windows Server Enhancements • ReFS Support • Online resize VHDX • Storage Tiering • SMB improvement • Hyper-V replica improvement • Faster live migrations

  22. End • Thank you for attending! • Phil Brammer • @PhilBrammer • http://www.ssistalk.com
