Traditional Data Centers are giving way to private and public cloud/fog.  Data Center storage using NAND flash has gained an upper hand over traditional spinning media.  With falling flash prices, there is an increased uptake of All-Flash Storage Arrays composed of faster and denser SSDs.  

The online world depends on Data Centers.  They occupy large building spaces that house servers and the accompanying storage and network. Servers take the centerstage when it comes to the online experience.  They are known as service-driven, application-specific computing machines that are highly adaptable.  They are reliable and capable of virtualization and consolidation, making daily operations simpler for network and database administrators.

The global data center trends are converging to HCI (Hyper-Converged Infrastructure) from the traditional data center architecture as they are smaller, simpler and more efficient. HCI is a purpose-built data center architecture that adapts easier than the others to the assigned purpose.  It simplifies operational and management tasks p (阅读更多)

The three components of data centers are compute, storage, and network.  Arranged in racks, towers, or silos, the servers (or compute) work with an array of hard or solid state drives (storage) and connect to the outside through rack-mounted switches (network).  The data center customer orders each component from selected hardware vendors and integrates them into a functional unit.
