Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environments.

Intel® VT-x?

Intel® VT-x with Extended Page Tables (EPT), also known as Second Level Address Translation (SLAT), provides acceleration for memory intensive virtualized applications. Extended Page Tables in Intel® Virtualization Technology platforms reduces the memory and power overhead costs and increases battery life through hardware optimization of page table management.

Intel® Demand Based Switching?

Intel® Demand Based Switching is a power-management technology in which the applied voltage and clock speed of a microprocessor are kept at the minimum necessary levels until more processing power is required. This technology was introduced as Intel SpeedStep® Technology in the server marketplace.

Just-in-Time Command Scheduling?

The memory controller integrated into the processor has an advanced task scheduling system that verifies all the queried requests simultaneously and decides which of them can be subsequently processed more efficiently.

Error-correcting code memory (ECC memory)?

It is a type of RAM that can detect and correct internal data corruption. ECC memory is used in servers where data corruption cannot be tolerated under any circumstances.
