THE MANY LAYERS OF SQL

SERVER

Windows Server™ O/S

SQL Server™ instance (SQLOS)

SQL Server™ Database(s)

Every server has the same

constraints:

SERVER OS CONFIGURATION OPTIONS

Every server has the same

constraints:

• Memory

• CPU

• Disk

• Network

Memory

• 32 v 64 bit

• Limits for Standard edition (64GB,

128GB)

• Virtualized host servers may be

over-allocated

• Power settings can cause CPU issues

• May need to set in BIOS

• Virtualized host servers may be over-allocated

• Mount points

• Clustering options

• SAN configuration

• Storage spaces

• 64K Allocation Unit Sizes

Network

• Named Instances

• Non-default ports

• Firewalls

• Anti-virus exclusions

Service Account Permissions

• Instant File Initialization

• Lock Pages in Memory

Memory

• Set your min/max values

• Default min = 0, max =

2147483647

• Max = 0, tells SQL to be dynamic

MIN((95% physical), (50% avail))

• Multi-instance don’t talk to each

INSTANCE CONFIGURATION OPTIONS

Cost Threshold for Parallelism

• Default is 5

• OLAP workloads = 25

• OLTP workloads = 40

Cost Threshold for Parallelism

• Default is 5

• OLAP workloads = 25

• OLTP workloads = 40

Max Degree of Parallelism

• Default is 0

• Consider NUMA when setting

Optimize for Ad-hoc Workloads

• Disabled by default

• You should enable this

• Unless you already know you

shouldn’t

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

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 = 8Add 4 at a time after that

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

Resource Governor

• Default is system pool only

• Use RG for dedicated

workloads

• Example: Hekaton workloads,

Maintenance

• Related: Query Governor

Backup compression

• Consider enabling

• Increases CPU – consider using

Cycle error logs

• sp_cycle_errorlog

• TF to turn off log backup

messages in error log - 3226

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

Filegroups

• Default is one (PRIMARY)

• Create at least two:

• System

• User

• Tables and indexes

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)

Auto defaults

• Autogrowth

• Configure smart values

• Update statistics

• Large tables consider TF 2371

• Create statistics

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

Optimistic Isolation

• Read Committed Snapshot

Isolation (RCSI)

• Should be considered when

workloads have high amount

locking/blocking

• Some tempdb overhead

Forced Parameterization

• Default is SIMPLE

• Leave it SIMPLE

• Unless you are the 1%

Trustworthy

• Default is OFF

• Leave it OFF

Standard OS builds

Consider using sysprep for SQL installations

5 THINGS YOU CAN DO BETTER

Scripted installs

Build checklist

Esp helpful AFTER applying SPs/CUs/Upgrades

Understand RPO and RTO, as they

impact your configuration choices
