Various factors come into play when you need to implement hardware within a new or existing infrastructure. Cost is a difficult consideration to master because you may need advanced technology, but not have the budget available to purchase new hardware. Used networking components supply needed technology without spending more than is available or forgoing functionality to meet pricing restrictions. A reliable supplier can provide refurbished equipment at a percentage of what new products cost. When you acquire servers from experienced secondhand distributors, you receive thoroughly tested equipment with warranty protection. The considerations required for purchasing used and refurbished servers are basically the same as for new hardware, with the exception of verifying supplier reliability. You should choose an equipment distributor that not only has a wide range of manufacturer inventories, but also a reputation for great service and quality.
Used Servers: What Are the Most Significant Buying Considerations?
Whether you are buying new or used servers, your biggest concern should be ensuring that the selected hardware meets the requirements of your business. Drivers, redundancy, hot swappable components, storage, CPU support, connectivity, memory capacity, and manageability are among the many items you must consider before making a final buying decision. One wrong choice in any of these areas can lead to a disappointing purchase where the product does not perform as required by your set infrastructure.
Driver support is easier to find when Windows platforms are used by your technology setup. You can purchase a server from any major manufacturer and be almost 100 percent certain the drivers will be supportable with a Windows based platform. Linux drivers are not as easy to accommodate and may require a little additional research before deciding on a manufacturer or specific line of servers.
You will need redundancy capabilities for mission-critical operations where a single point of failure can be devastating. Memory, power supplies, cooling, and other components should be backed by redundancy to ensure used servers can continue to operate if something should go wrong. Hot swappable components allow the system to continue running while parts such as the hard drive or power supply are replaced.
Internal storage can vary greatly between server models with common characteristics being the inclusion of two hard drives. Some designs boot off of SAN rather than a hard drive, meaning they have no internal storage. Others support immense storage arrays located within the storage hardware. Blade designs have two drives, but may be expanded with modules when chassis space supports this change. CPU architecture should be capable of accommodating future growth needs. Consider buying a server capable of accommodating CPU core additions.
Server hardware can have network connectivity built-in, but this may not meet the needs of your infrastructure. Setups involving clustering or virtualization technology involve more adapters than provided by a single storage device. Certain environments also require increased memory and management capabilities over others.
