IT Infrastructure from IQusion: Professional Services and High Quality
When a company grows or expands its office space, the network infrastructure, server complex, and power supply systems must operate as a single coordinated mechanism. IQusion specialists offer a systematic approach to designing, deploying, and supporting infrastructure solutions for corporate clients. Work areas cover building cable lines and deploying wireless communications, selecting servers and data storage systems, installing operating systems, databases (DBMS), and setting up workstations, as well as preparing the engineering environment (power supply, uninterruptible power supplies, cooling, physical access control) and subsequent support. In a contract for system integration services, it is worth specifying concrete deliverables: an agreed as-built diagram, equipment inventory list, access rights matrix, personnel instructions, and an acceptance testing protocol.
Design and Construction of Network Infrastructure
Stable operation of corporate services depends on the quality of the structured cabling system (SCS) and the wireless network. The process of creating a network environment begins with a premises survey, assessing the number of workstations, and calculating the required bandwidth of communication channels. The designer selects the configuration of cable routes, switches, routers, and Wi-Fi access points based on the actual needs of the facility, without overloading the project with redundant components.
For the wireless segment, access point coverage and load are evaluated. It is advisable to separate corporate and guest traffic, for example, using virtual networks (VLANs) and firewall rules. The NIST SP 800-53 Rev. 5 (2020) catalog can be used as a methodological reference for selecting security controls. Installation concludes with checking lines and connections; the scope of as-built diagrams and measurement results should be stipulated in the contract.
Servers, Storage, and Operating Environment
Server equipment is selected for specific business tasks: from ensuring the operation of domain controllers and mail services to supporting corporate databases and application software. Calculating the required computing power, RAM capacity, and disk array parameters relies on current load and predictions of data volume growth.
Configuring system software includes installing operating systems, disabling unnecessary services, installing current updates, and restricting administrative privileges to reduce the risk of unauthorized access (NIST SP 800-123). Establishing a standardized server configuration simplifies subsequent maintenance and regular software updates (NIST SP 800-128). At the workstation level, engineering personnel install office software, connect peripheral devices, and configure user accounts in accordance with the organization's security policy.
Engineering Systems: Power, Climate, and Access Control
Reliable operation of a server room requires creating appropriate climate and electrical conditions. Uninterruptible power supplies (UPS) protect sensitive equipment from voltage surges and provide a short buffer of time for saving data and performing a standard system shutdown. The required UPS battery runtime is calculated during design and verified in practice. If additional protection against prolonged power outages is needed, a generator can be included in the scheme, but its presence is optional.
To maintain the required temperature, air conditioning is installed in the room taking into account the heat output of the server equipment. Physical security is ensured by installing access control and management systems (ACS), which limit the group of individuals authorized to enter the room, as well as video surveillance systems that record events and equipment status. It should be noted that having a UPS or backup power solves only power supply issues and does not replace creating data backups.
Work Phasing and Practical Business Benefits
Sequential work phases help the client see intermediate results and approve expenses before equipment procurement. Documented diagrams and instructions reduce dependency on the knowledge of a single administrator. Tracking server loads and available network ports provides a basis for planning expansion. And agreed test scenarios allow assessing whether the built infrastructure fulfills business objectives.
- Phase 1: Audit and Survey — inspection of premises, inventory of existing equipment, and assessment of network line conditions.
- Phase 2: Design — development of specifications, equipment layout diagrams, power calculation, and access matrix approval.
- Phase 3: Installation Works — cable laying, rack assembly, server installation, connection of UPS and climate systems.
- Phase 4: Commissioning — OS and DBMS installation, configuration of network protocols and user rights.
- Phase 5: Acceptance Testing — testing system performance under various modes, failover testing, and signing the protocol.
- Phase 6: Handover into Operation — handing over diagrams, inventory statements, line specification sheets, and personnel instructions to the client.
Disaster Recovery Planning and Boundaries of Responsibility
The mere presence of file backups does not ensure service recovery in the event of a large-scale outage. To restore systems to an operational state, an IT infrastructure recovery plan is developed, describing the sequence of personnel actions and software launch priorities (NIST SP 800-34 Rev. 1 — a methodological guide for contingency planning). Regular test deployment of backups on a test bed enables estimating the actual time required to recover data.
Before starting work, it is worth establishing who is responsible for equipment, software applications, backups, and user inquiries after launch. Support terms should define communication channels, incident priorities, and agreed response times. This helps avoid situations where a problem is passed between multiple contractors without anyone responsible for its resolution. Facility requirements and scope of services can be worked out with specialists from IQusion IT consulting. The cited NIST materials are methodological sources, not proof of company certification or mandatory standards for all Ukrainian clients.
Questions and answers
Where does an infrastructure project start?
With a survey of premises, existing equipment, load, and service operation requirements. Based on this, the scope of equipment and project phases are defined.
Does a UPS replace backing up?
No. A UPS maintains power for a calculated period of time, while backups are required for data recovery. Both mechanisms are tested separately.
What should be provided for during acceptance testing?
Agreed test scenarios, as-built diagrams, inventory lists, instructions, and designated roles responsible for subsequent operation.
