- 11. www.sharepointsummit.org Latence Network Latency between web front ends and SQL Server • < 1 ms during10 minutes (1% failure max) • 1 Giga bits / sec • Mandatory for stretched farm, but good practice
- 12. www.sharepointsummit.org NTFS Allocation Unit Size 64K is optimal, 4K = 30% Performance Penalty Use chkdsk <drive>to Verify Use Format to Configure: • Format <drive> /Q /FS:NTFS /A:64K /V:<volume> /Y

- 14. www.sharepointsummit.org SQL Server configuration For SharePoint 2013: • SQL Server 2008 R2 SP1 • SQL Server 2012 (SP1 for BI) • SQL Server 2014 (SP2013 SP1 & April CU) Don’t install SSMS on the SQL Server computer Use named instances SharePoint Use a dedicated instance Run the service with a Managed account •No specific permission
- 15. www.sharepointsummit.org Collation settings Latin1_General_CI_AS_KS_WS (for SharePoint databases) (Any CI collation is supported for tempDBs, master, but Latin1_xxx_ is recommended) SP uses this collation when it creates its own db Cannot be changed after the setup
- 19. www.sharepointsummit.org Use alias for the connection string • Client alias or DNS alias (preferred) Good practice : every SP Content db must be created (and documented) by a DBA after a strict capacity plan
