Data processing and storage centers are a reliable comprehensive centralized system that ensures the automation of business processes with a high level of performance and quality of provided services. VERNA specialists provide a full range of services for building data center engineering systems.
The main advantages of implementing a modern data center network infrastructure:
• Ensuring the reliability of connections with servers and data storage systems.
• Ensuring scalability and flexibility when increasing computing power.
• Simplifying integration with other network infrastructure modules.
The design of the server farm (Server Farm) is based on a multi-level approach, which is key in building a data center network infrastructure and can be divided into three main levels: core, aggregation, and access.
Data Center Core Level provides high-speed packet switching for all data streams coming from the data center, connecting to aggregation modules, and ensuring reliable routing using dynamic routing protocols, and provides high-speed traffic transmission between the enterprise's local network core and the data center aggregation level.
Aggregation Level provides integration of service modules, termination of Layer 2 domains, and default gateway redundancy. At this level, services such as firewalls and server load balancing for application optimization and protection can function.
Data Center Access Level consists of modular fixed-configuration switches in 1 or 2 units.
Typical switches used in data center infrastructure meet the following requirements:
• Layer 2 and Layer 3 switches.
• Availability of 1/10-gigabit ports without oversubscription, with copper or optical connections.
• Virtualization or stacking capability for organizing reliable connections.
• Power redundancy.
The choice of a network solution for the data center is influenced by current and future services that will operate in the data center, server and storage equipment, its integration into the future network infrastructure, the required level of service - redundancy, reliability, and security level requirements.
VERNA specializes in designing and building multi-level environmental parameter monitoring systems for data centers.
Stages of building a monitoring system by VERNA:
• Determining environmental parameters in the data center, changes in which within certain limits or at a certain speed are critical for the operation of the customer's IT systems and business processes. For example, smoke (fire), water leakage, a sharp increase in temperature when the air conditioning and cooling system stops, power outage, etc.;
• Determining notification and warning algorithms for the duty personnel responsible for data center operation. For example, problem notification can be implemented in various forms: from a simple panel with sound and light signals to sending emails via messengers or SMS to pre-specified recipients;
• Designing the solution, selecting equipment and software, determining the location of equipment, sensors, etc.;
• Installation, calibration, test trials, and commissioning;
• Support and maintenance.
VERNA engineers are certified in data center monitoring and security solutions and perform all stages of creating monitoring systems: compiling and agreeing on technical specifications with the customer, designing, supplying, installing, calibrating, commissioning the monitoring system, and further support.
VERNA offers workstation virtualization solutions based on the VDI principle, which involves delivering the information system to a remote client regardless of the hardware and software architecture of the user's environment. Most implementations of this technology are based on storing virtualized workstations on a remote server. Thus, all user applications and information are executed and stored centrally on a dedicated server. This allows centralized management of the system, and users to work on the thin client principle using various devices.
Server Infrastructure Virtualization.
Virtualization is one of the most promising and effective approaches to optimizing IT infrastructure in the face of growing demands for computing resources. Virtualization technology can provide each virtual server with the resources of a physical server and distribute these resources among virtual servers depending on their needs. Each virtual machine operates with its own independent operating system and software set. Thus, on one hardware platform, it is possible to ensure the independent simultaneous operation of many virtual servers.
The virtual infrastructure can consist of various components: virtual machines, hypervisor, management software, additional software components, and hardware.
A hypervisor is a program or hardware scheme responsible for providing and distributing physical resources to virtual servers, their isolation, protection, and security.
Cost-effectiveness.
Server consolidation allows reducing costs not only on hardware but also provides cost savings on infrastructure management and maintenance. Using fewer physical servers helps reduce costs for power supply, air conditioning, and placement.
Ensuring reliability and security.
The virtualization environment allows creating solutions that provide the necessary level of reliability and security. With a wide range of available software components, it is possible to create infrastructures built on high-availability clusters, using fault-tolerance tools that ensure the isolation of hazardous environments, allow the use of backup and recovery tools.
Increasing efficiency.
Rational and efficient use of resources through shared use of hardware. The ability to manage resource allocation.
Application optimization.
Flexible configuration when creating hardware configurations of virtual machines. The ability to organize virtual machines into logical containers for specific applications. High manageability and mobility of virtual machines.
Scalability of capabilities.
Implementing new services does not require allocating separate physical servers. Using server consolidation allows rationally increasing production capacities depending on needs.
Flexible management capabilities.
Centralized management tools, extensive automation capabilities allow servicing the IT infrastructure as a whole, simplifying the work of IT personnel. Simplifying administrative tasks thanks to hypervisor tools and the absence of a large number of different hardware configurations.
Overall, virtualization is a powerful tool for optimizing and improving IT infrastructure. It allows ensuring cost-effectiveness, reliability, efficiency, and management flexibility, helping companies succeed in the modern digital world.
Thin client - a device or software whose operation principle is based on transferring computing functions and information processing tasks to a specially dedicated server used for these tasks. This is achieved through remote connection to servers using terminal access or VDI technologies.
This allows simplifying the architecture of thin clients and, consequently, obtaining the following advantages:
• Higher reliability. Fewer points of failure due to simplified architecture.
• Ease of setup, maintenance, and administration. Unified environment, configuration, availability of various management software, centralized user data storage.
• Improved security. Centralized data storage on specially protected servers, flexible security policy configuration.
• Budget savings. Reducing the total cost of the solution due to operational expenses.
The main ways to organize infrastructure using thin clients are the use of terminal access and VDI (Virtual Desktop Infrastructure). With terminal access, all computing work is performed on the terminal server, while the local terminal device performs KVM (Keyboard - Video - Mouse) functions. In this case, the thin client transmits commands from the local device to the terminal server and video images from the terminal server to the local device.
Data is a fundamental, integral part of information technology. Regulated, organized, proper information management is the key to the effective operation of IT infrastructure and the enterprise as a whole.
The purpose of backup:
• Disaster recovery. Restoring the entire or a significant part of the IT infrastructure in case of a disaster;
• Operational backup. Restoring deleted or damaged data to a specific point in time through operational intervention;
• Long-term storage. Backup for long-term storage. Performed to comply with established norms and laws in the field of information storage;
• Hardware failure;
• Software failure.
Backups can be deployed using the following main methods, depending on the load and capability of the backup source system:
• Hot Backup - a method where data can be used by applications during backup.
• Cold Backup - a method where the application is inactive during backup. The architecture of backup and recovery technologies.
Typical architecture is built on a client-server model and consists of the following main components:
• Backup Client - a component responsible for collecting data to be backed up, transferring data to the storage node, and retrieving data during recovery. It is also responsible for transferring metadata (service information) about files to the Backup Server.
• Backup Server - the main managing component responsible for managing and supporting backup and recovery operations. The Backup Server stores configuration information (supported clients, device information, backup schedule procedures, etc.), manages backup tracking.
• Storage Node - responsible for organizing information received from the Backup Client and writing data to backup devices. The storage node can control multiple backup devices. It also transfers metadata (service information) about the saved data set (saveset) to the Backup Server.
These are the main components of the architecture of backup and recovery technologies built on a client-server model.
