Why Windows Server Core ?
Benefits

 Ensure the server stability

 Less down time

 Smaller attack surface – higher security

 Reduce servicing and management requirements

 Reduce Hardware constraints : Disk / Memory

The perfect platform for databases and naturally SQL Server


Why Windows Server Core ?
Reduce OS patches

 If Server Core had existed
 Windows 2000 is ~60% reduction

 Windows Server 2003 is ~40% reduction

 Windows Server 2008:
 ~35% reduction if accepting all patches

 ~59% reduction if applying only necessary patches

 ~59% elimination of reboots

SQL Server Configuration
Configure Firewall
 Port de communication SQL Server

 Windows 2008
netsh firewall set portopening TCP 1433 "SQLServer"

 Windows 2008 R2
netsh advfirewall firewall add rule name=”SQL Server
default port 1433” dir=in action=allow protocol=TCP
localport=1433


Configure SQL Server Instance
 Apply best practices:
http://www.slideshare.net/dbiservices
/d-dbif20110830005sql-serverbestpractice

 Use SQL Server on remote with SSMS or directly SQLCMD:

sqlcmd -S <server><instance> -i W:sqlinstconfig.sql
sqlcmd -S <server><instance> -i W:tempdbconfig.sql


Useful Commands
 Enable and Start SQL Browser
sc config SQLBROWSER start=auto
net start SQLBROWSER

 New DMVs :
sqlcmd -q "SELECT * FROM sys.dm_os_windows_info“
sqlcmd -q "SELECT * FROM sys.dm_server_services“

 Identify all processes that are blocked for more than 10 seconds
sqlcmd -q "SELECT * FROM sys.sysprocesses WHERE
blocked<>0 AND waittime > 10000”

 Check if there are any deadlocks
sqlcmd -q "SELECT * FROM sys.dm_os_performance_counters
WHERE counter_name = 'Number of Deadlocks/sec‘ AND
cntr_value <> 0”


Checklist
 Install requirements like .Net 4 Core

 Install SQL Server in command-line

 Configure the Firewall for SQL Server ports

 Apply Best Practice to configure Instance

 Load or install the databases
