Direct Stream Digital (DSD) is a trademark used by Sony and Philips for their system for digitally encoding audio signals for the Super Audio CD (SACD).. DSD uses delta-sigma modulation, a form of pulse-density modulation encoding, a technique to represent audio signals in digital format, a sequence of single-bit values at a sampling rate of 2.8224 MHz.
A data center is a pool of resources (computational, storage, network) interconnected using a communication network. [1][2] A data center network (DCN) holds a pivotal role in a data center, as it interconnects all of the data center resources together. DCNs need to be scalable and efficient to connect tens or even hundreds of thousands of ...
Data center interconnect. A datacenter interconnect (DCI) is a connection between data centers and between the components within them. [1][2] The goal of a data center interconnect is to provide high bandwidth in order to maximize the utility of the data center. [2] Inter data center interconnects must also be able to transmit over long ...

Google data centers are the large data center facilities Google uses to provide their services, which combine large drives, computer nodes organized in aisles of racks, internal and external networking, environmental controls (mainly cooling and humidification control), and operations software (especially as concerns load balancing and fault tolerance).
The standard data center tiers are: [1] Tier I: no redundancy. Tier II: partial N+1 redundancy. Tier III: full N+1 redundancy of all systems, including power supply and cooling distribution paths. Tier IV: as Tier III, but with 2N+1 redundancy of all systems. A Tier III system is intended to operate at Tier II resiliency even when under ...
