6 THE MANY LAYERS OF SQL SERVER Windows Server O/S SQL Server instance (SQLOS) SQL Server Database(s)

7 SERVER OS CONFIGURATION OPTIONS Every server has the same constraints:

8 SERVER OS CONFIGURATION OPTIONS Every server has the same constraints: Memory CPU Disk Network

9 SERVER OS CONFIGURATION OPTIONS Memory 32 v 64 bit Limits for Standard edition (64GB, 128GB) Virtualized host servers may be over-allocated

10 SERVER OS CONFIGURATION OPTIONS CPU Power settings can cause CPU issues May need to set in BIOS Virtualized host servers may be over-allocated

11 SERVER OS CONFIGURATION OPTIONS Disk Mount points Clustering options SAN configuration Storage spaces 64K Allocation Unit Sizes

12 SERVER OS CONFIGURATION OPTIONS Network Named Instances Non-default ports Firewalls Anti-virus exclusions

13 SERVER OS CONFIGURATION OPTIONS Service Account Permissions Instant File Initialization Lock Pages in Memory

14 INSTANCE CONFIGURATION OPTIONS Memory Set your min/max values Default min = 0, max = Max = 0, tells SQL to be dynamic MIN((95% physical), (50% avail)) Multi-instance don t talk to each other

15 INSTANCE CONFIGURATION OPTIONS Cost Threshold for Parallelism Default is 5 OLAP workloads = 25 OLTP workloads = 40

16 INSTANCE CONFIGURATION OPTIONS Cost Threshold for Parallelism Default is 5 OLAP workloads = 25 OLTP workloads = 40 Max Degree of Parallelism Default is 0 Consider NUMA when setting

17 INSTANCE CONFIGURATION OPTIONS Optimize for Ad-hoc Workloads Disabled by default You should enable this Unless you already know you shouldn t

18 INSTANCE CONFIGURATION OPTIONS Physical file layouts Default is system install drive Set this during installation of SQL Server Distinct drives for data, log, backups Think about recovery first

19 INSTANCE CONFIGURATION OPTIONS tempdb configuration Default is system install drive SQL 2016 enhancements Ensure files are the same size Enable TF 1118 <8 Cores: tempdb files = cores >=8 Cores: tempdb files = 8 Add 4 at a time after that

20 INSTANCE CONFIGURATION OPTIONS SQL login passwords Authentication mode chosen during installation (mixed-mode) Set strong password for sa, then disable Default is CHECK_POLICY = ON PWDCOMPRE() system function

21 INSTANCE CONFIGURATION OPTIONS Resource Governor Default is system pool only Use RG for dedicated workloads Example: Hekaton workloads, Maintenance Related: Query Governor

22 INSTANCE CONFIGURATION OPTIONS Backup compression Consider enabling Increases CPU consider using RG Cycle error logs sp_cycle_errorlog TF to turn off log backup messages in error log

23 INSTANCE CONFIGURATION OPTIONS System Health event session Add event file Modify ring buffer (2008, R2) Blocked Process report Consider changing from default value of 0 Capture for blocked processes

24 DATABASE CONFIGURATION OPTIONS Filegroups Default is one (PRIMARY) Create at least two: System User Tables and indexes

25 DATABASE CONFIGURATION OPTIONS Compression Row and Page Can dramatically reduce data size Will be some overhead Must be set for each object manually (no database option)

26 DATABASE CONFIGURATION OPTIONS Auto defaults Autogrowth Configure smart values Update statistics Large tables consider TF 2371 Create statistics

27 DATABASE CONFIGURATION OPTIONS Compatibility mode Default is either model (new db created) or whatever the restore had previously Match instance version (SQL2014 = 120) Test this for your environment

28 DATABASE CONFIGURATION OPTIONS Optimistic Isolation Read Committed Snapshot Isolation (RCSI) Should be considered when workloads have high amount locking/blocking Some tempdb overhead

29 DATABASE CONFIGURATION OPTIONS Forced Parameterization Default is SIMPLE Leave it SIMPLE Unless you are the 1% Trustworthy Default is OFF Leave it OFF

30 5 THINGS YOU CAN DO BETTER Standard OS builds Consider using sysprep for SQL installations

31 5 THINGS YOU CAN DO BETTER Scripted installs

32 5 THINGS YOU CAN DO BETTER Build checklist Esp helpful AFTER applying SPs/CUs/Upgrades Automate system checks

33 5 THINGS YOU CAN DO BETTER Understand RPO and RTO, as they impact your configuration choices

34 5 THINGS YOU CAN DO BETTER HA <> DR Understand RPO and RTO, as they impact your configuration choices

35 5 THINGS YOU CAN DO BETTER Use Policy Based Management
