Data Centers are sophisticated network infrastructure systems that incorporate a variety of storage and processing solutions, delivering high-speed operations, high resiliency and reliable data security. The rapid increase in the amount of information requires the continuous improvement of existing equipment, imposing appropriate requirements on the speed and reliability of data exchange, methods and principles of reliable storage of information.
The efficiency of data processing and storage is driven by the use of advanced solutions from the best technology brands for data centers, the leaders of the global network industry.
Traffic Load BalancingLoad balancing improves workload allocation across multiple computing resources: computers, clusters, network connections, CPUs, or disk drives. Traffic balancing allows you to optimize resource utilization, maximize bandwidth, minimize response time, and avoid overloading of individual resources. The use of multiple balancing components instead of a single component can increase reliability and availability with the resulting power reserve. Load balancing usually involves the use of special software or hardware....
Virtualization SystemsVirtualization, as the process of migrating application software, operating systems, server devices, repositories, and networks to the virtual plane, has long been a major trend in storage and data sharing. The main benefits include improving productivity and availability of resources, scalability, ease of administration, flexibility of deployment and process automation.
Known to date virtualization systems:
ESXi and vSphere from WMware are the leaders in virtualization, they are very popular due to the accessible interface, versatility in support of various operating systems, wide functionality, supported by a large amount of technical documentation;
Hyper-V, a Microsoft product based on OSWindows Server, is an easy-to-configure and maintain hypervisor that supports all versions of Windows operating systems;
KVM (Kernel-based Virtual Machine) - a virtualization solution for Linux / x86 platforms, is universal in terms of support for other versions of operating systems, supports hardware extensions (Intel VT and AMD-V);
OpenVZ - a free virtualization system implemented on the Linux kernel;
Proxmox Virtual Environment (Proxmox VE) - an open source virtualization system based on Debian GNU / Linux (debian version 1.x, debian 6 version 2.x);
Xen is a versatile hypervisor designed at the University of Cambridge's computer lab and licensed under the GPL. The main features: support for the mode of paravirtualization in addition to hardware virtualization, the minimum code of the hypervisor itself due to the removal of the maximum number of components beyond the hypervisor.

Data Center Network InfrastructureDesigning a data center network infrastructure, regardless of construction options, is based on the pursuit of excellence by such criteria as: performance, fault tolerance, scalability, security, data protection, management, virtualization, integration with other systems. In place of the classic kernel-aggregation-access topology, new solutions have emerged that have improved the flow of data not only from north to south, but also from east to west. The development of new networking equipment takes into account the use of both classic and LEAF-SPINE networks, a software-oriented infrastructure.

Data Storage SystemsThe Data Storage System (CPA) is a comprehensive software and hardware solution for the organization of secure storage of information resources and the provision of guaranteed access to them. CPAs can be both part and base of the Data Center (DOD).
There are several types of connection:
Direct Attached Storage (DAS) - Direct Connected Storage Systems. When using DAS, the server has a personal connection to the CPA and is almost always a single user of the device. In this case, the server receives block access to the storage system, that is, accesses directly to the data blocks.
Network Attached Storage (NAS) - Networked storage systems, also known as file servers, provide their network resources to clients over the network in the form of shared files. Clients use network file access protocols such as SMB (formerly known as CIFS) or NFS.
Storage Area Network (SAN) - A storage network that provides clients with block access to network data. Devices in the SAN do not belong to a single server and can be used by all storage clients. It is possible to split the disk space into logical volumes that are allocated to separate host servers. These volumes are independent of the SAN components and their placement. Clients access the data warehouse using block-type access, as with DAS connectivity, but since SAN uses the network, storage devices can be located far away from clients.
Universal Storage Systems (UnifiedStorage) combines NAS and SAN technologies in a single integrated solution. These versatile repositories make it possible to use both block and file type access to shared resources, in addition, the management of such devices is easier thanks to software that provides centralized management....
Hyper-Converged Solutions for Data CentersHyperconverged solutions combine computing power, high-speed storage systems, network infrastructure and are managed with a single software product.
Hyperconvergence is a software-driven infrastructure that allows you to separate the operation of infrastructure from hardware and combine them at the hypervisor level into one structural unit, which becomes hyperconverged.
Hyperconverged systems use software-driven intelligent tools to eliminate the fragmentation of computing resources and data storage systems, providing the ability to execute and manage them on the same server platform, thereby eliminating inefficiencies and speeding up computations....
