Engineer review before you buy: RFI and A/B options for IT equipment
Before ordering servers, network gear or a firewall, an engineer checks the requirement, an RFI pins down the real need, and ONYX prepares two options: a fully compliant A and a value-engineered B.
In this article
An engineer review before purchase means that before a server, network device or firewall is ordered, an engineer checks the requirement, a questionnaire (RFI) pins down what is really needed, and two options are prepared: option A, fully compliant with the stated requirement, and option B, value-engineered for lower cost with the trade-offs explained. This article explains how the process works and how to read the quotes you get.
ONYX was founded in Baku in 2019. It supplies corporate customers with servers, network equipment, firewalls and licences (Microsoft, for example), and delivers turnkey projects: office and branch IT setup, server rooms, network and security, cloud migration and structured cabling. For any risky or expensive order the approach is the same: engineer first, quote second.
Why "order now, fix later" fails
Equipment is often bought from a spec sheet, but problems show up outside the sheet. The server does not fit the rack, cooling falls short, the licence type does not match the application, and nobody remembers the support terms. The cost then arrives twice: once for the purchase, once for the correction.
An engineer review reduces that risk before the order, because the questions are asked while no money has been spent.
The RFI: a requirements questionnaire
An RFI (request for information) is a simple document that puts your real need on paper. The more precise it is, the better the quote fits. A good RFI covers:
- Users: how many, at which sites, and whether people work remotely.
- Applications: what will run and what each one demands.
- Growth: what is likely to change over the next few years.
- Uptime needs: what an outage costs the business and how long it can be tolerated.
- Power, cooling, rack space: whether the existing room can carry the new equipment.
- Licences: which software is needed, for how many users and devices.
- Support terms: response time, replacement, who gets the call.
- Delivery and warranty: lead time, acceptance, warranty conditions.
A and B: two options, a clear choice
Once the RFI is answered, ONYX prepares two options. Both rest on the same requirement but follow different logic:
| Option | Logic | Best for |
|---|---|---|
| A | Fully compliant with the stated requirement | Projects where the requirement cannot be compromised |
| B | Value-engineered: lower cost, with the trade-offs explained | Buyers with a limited budget who want to know which compromises are acceptable |
The key point is that B is not a quiet downgrade. What you give up is written down in advance, and the decision is yours.
How to read two quotes
The total is only one column of a quote. When comparing two offers, check:
- Is each line the same model and configuration?
- Do the licence type and term match?
- Are support and warranty terms written down, or only promised verbally?
- Are delivery and installation included?
- Is the equipment original vendor equipment?
Why "cheapest that matches the spec" can still fail
Matching a table does not guarantee it works. Two devices with the same specification can come with different support, licensing and warranty terms. The lowest price often comes from leaving those terms out. The project then becomes expensive not in year one, but when the first problem appears.
Original equipment and a documented handover
ONYX supplies original vendor equipment. Vendors you can work with include Cisco, Dell, HP/HPE, Lenovo, Fortinet, Palo Alto, MikroTik and Microsoft. A project ends with a documented handover: what was installed, how it is configured and what is left for whom, in writing. Without documentation, the knowledge leaves with the engineer.
One contractor from procurement to daily operation
Buying hardware from one company, installation from another and support from a third spreads accountability thin. ONYX can cover the whole chain as one contractor: requirements, procurement, installation, handover and day-to-day support. See equipment supply, infrastructure services and business solutions.

Frequently asked questions
What is an RFI and why fill one in before buying?
An RFI is a requirements questionnaire. It captures users, applications, growth, uptime needs, power, cooling, rack space, licences, support terms, delivery and warranty. Its purpose is to settle what is really needed before anything is ordered.
What is the difference between option A and option B?
Option A fully matches the stated requirement. Option B is value-engineered: it costs less, and the trade-offs you accept in return are explained openly. The choice stays with you.
How do I compare two quotes?
Look at what is inside, not only the total: exact model, licence type and term, support terms, warranty, delivery and documentation. Each line in one quote should be the same thing as the matching line in the other.
Do I have to buy only from ONYX to use this approach?
No. An RFI and A/B comparison works with any supplier. ONYX applies it to risky or expensive orders and can cover every stage from procurement to daily operation as a single contractor.
