What kind of architecture is MS SQL Server?
MS SQL Server is a client-server architecture. MS SQL Server process starts with the client application sending a request. The SQL Server accepts, processes and replies to the request with processed data. Let’s discuss in detail the entire architecture shown below:
How are CPUs assigned to virtualized SQL servers?
For virtualized SQL servers, licensing is based on the logical CPUs assigned to the VM running SQL Server. If the logical CPUs are from virtualization servers that are hyperthreaded, then you are licensing based on hyperthreaded CPUs.
How to determine how much CPU is available for SQL Server?
Determining how much CPU is available for a SQL Server involves: Inspecting licensing agreements and NUMA configurations to determine if there are any limitations on available CPUs Evaluating which scenario is a best fit in terms of usage, configuration and licensing costs
Do you have to license CPUs for SQL Server?
On a physical server running SQL Server, all the cores on the server must be licensed for SQL, even if that is more CPU capacity than your SQL instance requires. On a VM, you only need to license the logical CPUs allocated to the VM, with a minimum of 4 license units.
How big can images be stored in SQL Server?
Data Types For Images. For storing images you have to make use of the varbinary (MAX) datatype. The image datatype will Getting the best of both worlds with FileStream. Filestream storage was introduced in SQL Server 2008. Varbinary (max) can only store images with a maximum size of 2 GB.
What are the data structures in SQL Server?
System level data structures − Holds SQL Server instance level data about databases and locks. Log cache − Reserved for reading and writing transaction log pages. Connection context − Each connection to the instance has a small area of memory to record the current state of the connection.
