- 6. Disk layouts TempDB Logs Database OS Backup Prioritize Separate drivesfor different purposes Prioritize for faster disk • TempDB • Logs • Database 6
- 7. Storage Disk block size SQL Serverpages are 8k in size Extents are a collection of eight pages Format drives with 64k allocation unit 7
- 8. Antivirus exclusions File types toexclude: • • • • *.mdf *.ndf *.ldf *.bak Clustering also exclude: • <$windir>/cluster • Witness quorum disk (if deployed) 8

- 10. Memory acquired isNOT released Unless OS reports memory pressure Dynamic memory management Min server memory Min amount that SQL Server process may trim in event of memory pressure Max server memory • Max amount that SQL Sever process can allocate to the buffer pool • Recommend to set to total MB minus OS + app overhead 10
- 11. Memory to Leave forOS SQL Server Max Server Memory 16GB 4GB 12GB 32GB Memory Allocation Physical Memory Setting 6GB 26GB The general recommendation is to always set Max Server Memory and to leave some memory to always be available for the OS. SQL server will give back memory SQL Max Memory = TotalPhyMem - (NumOfSQLThreads * ThreadStackSize) - (1GB * CEILING(NumOfCores/4)) 64GB 8GB 56GB if OS 0) NumOfSQLThreads = 256 + (NumOfProcessors*- 4) * 8 (* If NumOfProcessors > 4, elsememory runs low but there can be OS memory stress if SQL ThreadStackSize = 2MB on x64 or 4 MB on 64-bit (IA64) 128GB 16GB 112GB 256GB 16GB 240GB does not respond fast enough to sudden memory demands from other processes on the system. 11
- 12. TempDB files Same numberof data files as CPUs Max of 8 Use RAID-10 Pre-size TempDB files Set Auto Growth to Fixed size <200 MB Only one transaction log file 25% of largest DB size SELECT * FROM sys.dm_os_schedulers 12
- 13. Model database file settings • • SharePoint databasesare based off Model Consider changing the settings 13
- 14. MAXDOP for SharePoint mustbe 1 Max Degree of Parallelism Error message when creating new SP2013 farms Controls the number of processors that can be used to run a single SQL Server statement 11/24/2013 14
- 15. Other “Stuff” Instance collation Latin1_General_CI_AS_KS_WS Windows authentication Autoshrink set to off (case-insensitive, accent-sensitive, Kana-sensitive, and width-sensitive) Access Services requires Mixed Mode! Otherwise causes high fragmentation 11/24/2013 Set Fill Factor to 80 15

- 19. Naming standards A standard isbetter than no standard No GUIDS Consider multiple Farms and environments 19
- 20. Detecting index fragmentation Use ALTER INDEX (REBUILDor REORGANIZE) to defrag indexes 20
