Dear Experts, Need you advise on, what should be the maximum memory to be set for sql server running data warehouse. my server configuration is: 32 GB RAM. with 7 databases on it. each database currently is around 100 GB. It also has SSRS,SSIS,SSAS configured on it.
Thanks. |

| SQL OS will grab as much memory as it is allowed to and does its own memory management. It may not do so initially when you start up the server, but when you run queries it will gradually take up more and more memory up to the limit it is allowed to. What it does is hold on to the memory it grabbed (which allows it to keep data, query plans etc. in memory, so if the same data is needed again, it can provide a faster turn-around). |

Sunita, Thanks for the detail. |

Some othe rconsiderations may include : a) Lock Pages in Memory. Yes or No ? This will depend on different scenarios. The main benefit of turning it on is that the buffer pool buffer doesn't get paged out.
b) Consider how much memory the other apps may take - such as AntiVirus
