SQL Hardware Selection

x64 Windows and x64 SQLOnly x64 support in future versions

Loads of RAM for SQL

4GB 16GB (why more memory)Choosing server class hardware

Scaling out always an option withSharePoint

Database Configuration

Data File Characteristic: TLOG = Sequential Write IODATA = Random Read and Write IO

Separate TLog and Data onto separateDisksSeparate Databases onto separateDisks

Disk I/O Optimization

Partition Alignment

Behavior prior to Windows Server 2008create partition primary align=format fs=ntfs unit=64K label="" nowait

Chose RAID Configuration appropriatelyConfigure SAN appropriately


16/34

SharePoint DBs

ContentMax Size 100GBSite Collections / Database

Use RAID 5 for data (or even better RAID10)Use RAID 10 for logs

Usage is highly variable based on SharePointusage

SearchUse RAID 10 logical units

Usage is extremely read/write intensive


17/34

SQL Server TempDB

Create additional secondary files of equal size

Optimal TempDB data file sizes can be

calculated using the following formula: [MAX DB SIZE (KB)] X [.25] / [# CORES] =DATA FILE SIZE (KB)

Rule of thumb: Calculation result

(starting size) should be roughly equalto 25% of the largest content orsearch DB.

Best managed by monitoring usage Trace Flag -T1118

I/O Performance

MeasurementPerformance Monitor Counters towatch:Disk Read/sec and Write/sec

Compared with maximum achieved during test Typical systems will perform 100+ per spindle

Average Disk sec/Read and sec/Write< 5ms for log writes and 100ms you will have a performance problemAverage Disk Queue Length

Not the best measure in my opinion, compareto baseline

Using Database Aliases

Allow content database to be moved toother instances with no configchanges in SharePoint

Can use DNS changes to move DBsto alternative instance in the case of database mirroring SQL Server Client Alias

DNS Lookup

Instance Name

Resolution

SQL 2005 or 2008Browser Service

Windows DNSService

CNAME Record

A Record

Connect to SQL SQL 2005 or 2008Database Service

SQL Server Name = SQL Server NameSQL Server Name = Host Name, PortSQL Server Name = IP, Port

If port unknown then lookup instance usingSQL Server Browser Service

If IP unknown then lookup hostname usingWindows DNS Service

What not to do

Dont do anything else with these dBsNo new indexesNo new tablesNo stored procedure changes

Couple of well known exceptionsMoving tables to filegroups to separate IO
