SQL Server Memory & Storage Technology

SQL Server- Understanding Server Storage Technology Explained

First we need to understand the different types of memory below

a.Static random access memory (SRAM) comprising L1 and L2 caches for each physical core of a processor,larger but slower shared L3 cache for the entire processor.

b. Dynamic random access memory (DRAM) which also our RAM we install/upgrade in servers.

Both SRAM and DRAM are volatile and hold data only when electrical power is on.

c. SATA/SAS SSD hard drive(NAND)

d. Magnetic spinning media hard disk drives.

Each of Storage/memory above cost lower per MB or GB with higher total capacity as you go from a to d above.

Now New NVM Express PCIe SSD’s (NAND). These are really good with latency … Read the rest

SQL Server 2016 New Features In-Memory OLTP enhancements

SQL Server 2016 New Features In-Memory OLTP enhancements

1. SQL Server In-Memory OLTP – Parallel and heap scan for memory-optimized tables

Heap scan is also supported which can be performed in parallel which is scanning of all the rows in a table using the in-memory heap data structure used for storing the data.

2. SQL Server In-Memory OLTP -Transact-SQL/TSQL Improvements for memory-optimized tables

a.UNIQUE constraints and indexes are supported.
b.FOREIGN KEY references between memory-optimized tables are supported.
c.CHECK constraints are supported.
d. NULL values are allowed
e.Trigger’s are supported.

3. SQL Server 2016 In-Memory OLTP Storage format is now changed
