2 SQL Saturday Nashville & Precon Virtualization for SQL Server DBAs Friday, January 17 th 8:30a to 4:30p Details and link to EventBrite registration at SQL Saturday January 18th Register today! 3 Agenda What is Virtualization? Why Virtualize? Infrastructure Underneath Benefits for DBAs Benefit Examples 4 2

3 Virtualization What Is It? 5 What is Virtualization? Added layer between hardware and operating system Hardware treated as physical resource queues Extension of the hardware, so is treated as part of the platform Not just P2Ving a single server Most DBA s virtualization experience 6 3

4 Terminology Virtual Machine / Guest Hypervisor Physical Machine / Host Template Cloud (Public / Private) Over-Committed Consolidation Live Migration / vmotion 7 Traditional Computing Local Disks (OS, Instance Home) SQL Server A (10% utilization) SQL Server B (12% utilization) SQL Server C (15% utilization) 8 4

5 Virtualization Computing (75% utilization) VIRTUALIZATION 9 Why Virtualize? And Why Should DBAs Care?

6 Business Cases Reduced costs Datacenter efficiency, consolidation & simplification Increased agility, flexibility, & responsiveness Business continuity Software development lifecycle Automation Simplified management Security 11 How Does It Help DBAs? High Availability & Disaster Recovery Snapshots for system-state rollback Capacity management - quickly Less downtime with equipment upgrades or maintenance Ease administration Cloning & templates Standardization Better Performance

7 How Does It Hurt DBAs? One extra layer Not dedicated infrastructure resources Lack of infrastructure-level visibility Silent performance killers Insufficient physical resources Poor performance FUD! 13 Infrastructure What is Underneath Your Data

8 In The Beginning Virtualization s historical draw is datacenter consolidation Extremely high overhead from virtualization layer Virtualize Dev/ Test / QA Virtualize tiny / simple Production Low resource allocations to s Performance impact rarely mattered 15 Today s Technologies Virtualize everything Tier-1 production Almost zero virtualization overhead Extremely mature technologies Easy to configure and manage SSD host-level read caching Virtual storage, networking, security Infinitely scale the datacenter Public / private / hybrid cloud models

9 Hypervisor Options (Q1 2014) ware vsphere 5.5 (ESXi + vcenter) Microsoft Hyper-V 2012 R2 (Hyper-V + SCCM + SCM) 17 vsphere 5.5 & Hyper-V 2012 R2 ware vsphere vcpus / 1TB vram 62TB x 180 virtual disks 62TB Raw Device Maps HA & Load Balancing 399 OSs Supported vcenter included Microsoft Hyper-V 2012 R2 64 vcpus / 1TB vram 64TB x 256 virtual disks 256TB Pass-Through Disks HA & Load Balancing 46 OSs Supported Need System Center & SCM

12 Benefits for DBAs Get The Most From Virtualization 23 High Availability 2013 Heraflux Technologies 24 12

13 Disaster Recovery SQL Server A App Server B 15 minute replication 60 minute replication WAN SQL Server A App Server B Virtualization Virtualization Primary Site DR Site 25 Snapshots

14 Capacity Management 27 Templates & Cloning Build master gold template Deploy new from template in minutes (vs. days) Configuration guaranteed

15 Standardization Use template to standardize the build Deploy from template Best practices always applied Know where all objects are located Makes automation possible 29 Benefit Examples Benefits Go Beyond the Obvious

16 Virtualization Benefit Example System backup and restore testing Restore your -level backups to a new on an offline virtual network Clone domain controller into offline virtual network Power on everything Validate that the server comes up Now validate your SQL Server functionality Validate SQL Server-level backups Destroy the s when complete CERTIFIED RECOVERY 31 Performance Benefit Example (1) High transactional volume application? Long-running ETL data loads? iperfhow-to guide: Move a lot of data between two s?

17 Performance Benefit Example (2) Collocate two s on the same host to increase virtual network performance 33 Conclusions Don t fear virtualization embrace it ( cuzit s here to stay) Virtualize everything with confidence Revisit your operational procedures Smart architecture can simplify Smarter architecture can possibly improve performance
