Hardware is the unsung engine of modern business. We often hear and talk about the cloud and Software as a Service or SaaS, but hardware – such as servers, storage arrays and networking switches – provides the underlying platform upon which all our applications are delivered.
Selecting IT hardware for your organization is not simply a purchasing decision. It’s a strategic decision that has lasting impacts on your organization’s availability, integrity and financial success. Selecting unbuffered RAM or an inappropriate RAID controller can cause hours of lost time and tens of thousands of dollars in lost revenue. The purpose of this guide is to serve as a reference and provide insight in relation to choosing hardware that can not only meet today’s needs but those of tomorrow as well.
1. Defining Reliability in the Business Context
When it comes to choosing supplies for reliable operations in commercial environments, it’s important to understand what reliability means. Switch on and switch off isn’t quite what we mean. Reliability is about being dependable.
The Enterprise-Grade Benchmark
The most common mistake that growing businesses make when building up their IT infrastructure is falling victim to prosumerism. This is when businesses choose to buy low-cost business servers (which are effectively high-end consumer PCs) in order to reduce CAPEX (Capital Expenditure). They buy a high-end consumer PC for the usual reasons, and at first sight, it appears to meet all of their corporate requirements. However, they frequently overlook the fact that consumer-grade computers are not equipped with the architecture necessary to run commercial systems.
- Duty Cycles: Consumer grade systems are only designed for an 8/5 duty cycle. Enterprise systems are built for a 24/7 duty cycle.
- Vibration Resistance: Multiple spinning disks and high-RPM fans create vibrations in a server rack that can crash consumer-grade HDDs. Enterprise drives include sensors to counteract this.
- Error Correction: Business Quality Hardware Will typically use ECC (Error Correction Code) RAM which can catch any data corruption in real time, something that consumer level systems do not necessarily offer.
2. Storage Architecture: Protecting Your Most Valuable Asset
Data is the lifeblood of every business, organization and project in today’s digital age. Therefore, the underlying storage systems – in the form of servers, hard disk drives, shop solid state drives etc, are arguably the most important piece of infrastructure in that business.
The Power of the RAID Controller
At the heart of any server or high-performance workstation is the RAID controller. It takes the multiple physical disk drives in the system and presents a virtual disk or disk array to the operating system. RAID stands for Redundant Array of Independent Disks. This is a storage setup where multiple disks work together to provide improved performance and or redundancy.
When selecting a RAID controller, consider the following reliability pillars:
- Hardware vs. Software RAID: The best solution is always a hardware RAID controller when it comes to redundancy. A software RAID would be very CPU-intensive, which could cause problems if the OS fails and locks up. In a hardware RAID solution, there is a separate processor and memory that controls data redundancy. So, in the unlikely event of an OS failure, the disks are still protected.
- Flash-Backed Write Cache (FBWC): The data in the controller’s waiting room (cache) could be lost in the event of a power failure. A reliable controller should always be equipped with either a battery backup or use a flash capacitor to hold data in the cache until the power is back on.
- Hot-Swap Support: Reliability also means serviceability. Having to take down a server because a disk needs to be replaced is not really reliable. A good RAID controller allows the disks to be removed and replaced while the server is still operational, and this can be done while personnel are handling other matters – eliminating the possibility of a team being blocked due to disk failures.
3. Power Infrastructure: The First Line of Defense
Hardware reliability can often be made to look far worse than it really is due to the adverse effects of dirty power on hardware components. These effects include variations in the supply voltage, brownouts and power outages, all of which can actually cause physical hardware damage to components.
Redundant Power Supplies – RPS
Every server and switch should have redundant power supplies. Ideally these should be dual hot swap PSUs so in the unlikely event of a PSU failure the system will keep running and the user may not even know they failed. Even if you have redundant PSUs, make sure you have redundant power feeds or that they are plugged into different UPS units. This way if a PSU fails, you’ll still have power flowing into the other one.
Thermal Management and Airflow
Heat is the biggest threat to the longevity of the electronics. When choosing a hardware vendor make sure to consider the chassis design.
- Redundant Fans: Can the system keep cooling itself if one fan fails?
- Sensor Integration: Does the hardware report its temperature to your management software?
- Airflow Efficiency: To ensure Airflow Efficiency in your server room, you need the right hardware. Modern day server components are all designed assuming that airflow is front-to-back.
4. Scalability: Avoiding the Forklift Upgrade
True reliability means that the hardware of your system is scalable and will grow with your business. If you have to replace an entire system every 12 months because the capacity has been exhausted, then the system is not a reliable investment.
Modular Architecture
Look for hardware that supports modular growth. This includes:
- Empty DIMM slots: Can we add more RAM next year using new DIMMS without having to dispose of our current RAM?
- PCIe Expansion: Does the motherboard have enough lanes to support future upgrades like 25GbE networking or AI-accelerator cards?
- Drive Density: Choose a chassis that has more drive bays than you currently need. This will allow you to grow your storage array through your RAID controller using Online Capacity Expansion (OCE).
5. Vetting the Supply Chain
Where you buy your hardware matters just as much as what you buy. The global IT supply chain can be complicated, and ‘grey market’ hardware, which looks real but does not have official support, can be a big risk.
Authorized Partnerships and Firmware
Always buy your hardware from authorized partners. It offers you several important benefits:
- Genuine Firmware: You receive official security patches for your BIOS and RAID controller.
- Validation: Use parts that have been tested to work together. Mixing random parts, sometimes called ‘Frankenstein’ builds, often leads to strange errors that are very hard to fix.
The Role of Refurbished Hardware
For many businesses, buying certified refurbished hardware is a good way to get reliable equipment while saving money. Just make sure the supplier gives you a warranty that lasts as long as a new product. In fact, refurbished products are often tested more carefully than new items from the factory.
6. Connectivity: The Networking Backbone
if your network hardware is unreliable then the fastest server will not help. When picking switches and routers, keep these things in mind:
- Backplane Bandwidth: Make sure the switch can handle the full combined speed of all its ports at the same time.
- Stickability: Pick switches that you can manage together as one unit. It makes your network simpler and helps prevent setup mistakes. This is the common reason for network problems.
7. Lifecycle Management: Planning for the End
If you are planning to buy new hardware parts then check their lifecycle. Consider Hardware products which comes with 3 to 5 years warranty for business equipment.
- End of Life – EOL Awareness: Check if the manufacturer warranty before making any purchase. If manufacture provide limited duration warranty, then don’t consider this product for bulk purchases.
- Standardization: Try to use the same models throughout your office. It makes easier to keep spare parts. So, if any IT hardware damaged of fail, you have a replacement ready right away.
Final Thoughts
Choosing reliable IT hardware solution offer balance of technical needs, your budget and your long-term plans. When you avoid consumer-grade shortcuts and focus on features like backup power, easy upgrades and dedicated RAID controllers, you are not just buying equipment. You are investing in keeping your systems running.
In this digital era, your IT setup shows your business reputation. If you build it on reliable hardware, your business will have the stability it needs to grow.
