It provides geographic information resources in the form of services via Internet \/ intranet networks, and allows to optimize internal work processes, solve production problems, coordinate the activities of various services.<\/p>\n<p>To solve the task set by the customer and to increase reliability, a two-node cluster was built on the basis of high-performance server hosts running the Windows Server operating system. The nodes of the cluster are Hewlett-Packard servers, which guarantee high productivity and full compatibility of the complex.<\/p>\n<p>In the cluster, a virtual high availability environment is deployed on the basis of Microsoft Hyper-V virtualization technology and the software components are installed (cartographic ArcGIS server, SQL server, WEB server, file server).<\/p>\n<p>To improve system performance and simplify maintenance operations and create backup copies of data, the database and images of virtual machines are stored on a network storage of data (storage).<\/p>\n<p>The network storage is equipped with an additional controller that provides higher availability and performance. Aruba level 3 managed switch allows to obtain high bandwidth of the local network and simplifies integration into the existing infrastructure<\/p>\n<p>To improve performance and fault tolerance, network connections are integrated into a trunk, and server-to-storage links are duplicated.<\/p>\n<p>The project implementation required installation and configuration of the directory service, firewall, terminal server, certification authority and infrastructure services, such as AD, DHCP, DNS. Configuration of management tools for servers, data storage and uninterruptible power supplies were completed.<\/p>\n<p>The domain controller and database servers were clustered at the virtual server level to provide fault tolerance.<\/p>\n<p>User workstations and the cluster operate in a leased network infrastructure with their own AD.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=&#8221;.vc_custom_1507631438298{margin-bottom: 15px !important;}&#8221;][vc_column]<div class=\"dt-fancy-separator title-left h3-size accent-border-color\" style=\"width: 100%;\"><div class=\"dt-fancy-title\"><span class=\"separator-holder separator-left\"><\/span>Result of project implementation<span class=\"separator-holder separator-right\"><\/span><\/div><\/div>[vc_column_text css=&#8221;.vc_custom_1515512635319{padding-top: 20px !important;}&#8221;]A two-node cluster based on HP servers was built.
