Where to buy server

Our advanced, build-to-order solutions are powering enterprises, data centers, universities, and government agencies. I tend to research what I want to buy pretty heavily, and then I want to order exactly the hardware I want. They very quickly provide me with a quote for exactly what I want with very minimal back and forth.

The few times when some issues came up, it was quickly fixed to my satisfaction. However, I appreciated the prompt customer service and follow up after our order was placed. If your product quality, technical support, and warranty services match our experience so far, we will certainly be a repeat customer.

Just a few years ago, one server typically handled a one task for office IT. One provided user credentials for accessing a database; another dedicated server managed the sending and receiving of e-mails; a different server was used for distributing Windows , another server for hosting a Web domain, and so forth. This might still be standard practice at a small business, but server management has changed drastically for larger companies within the past decade.

Now, medium and large organizations can save on server hardware costs by consolidating infrastructure onto one or a few enterprise servers. Modern enterprise servers can tackle several tasks with virtualization technology. Server virtualization uses a software application called a hypervisor to divide the computing power of a physical server into several virtual machines VMs —commonly called instances, or containers in IT semantics.

When looking at system specifications for servers for virtualization, look for high memory RAM capacity and number of CPU cores and CPU threads—all of which factor heavily in workload consolidation.

Knowing a few specifics about server hardware will help tie server specifications to system needs when buying a server or building one from components. The basic component structure of a server is similar to that of a PC. Servers for virtualization have motherboards with LGA sockets that support larger CPUs with the X99 chipset Intel Xeon E5 and Intel Core i7 X-series processors, for example that have multiple cores and threads for running virtual machines.

When you talk about scalability in servers, one huge consideration is the number slots in the motherboard. The more slots there are, the more room there is for expansion.

The number of cores and threads dictates performance for server CPUs. Clock speed, measured in GHz, plays a role in how fast the processor executes instructions, but in terms of functionality for modern servers, frequency does not gauge performance as much.

A larger amount of cache memory boosts performance: the cache stores frequently accessed data for faster recall, which speeds up server performance in many situations. Budget-level dedicated servers and NAS typically have a low-power dual- or quad-core processor Intel Core i3 typically found in PCs; more expensive servers have CPUs capable of greater processing power are more common in large tower servers and rack models.

Every server is meant for network use. Bandwidth considerations are important; inadequate networking components will sap performance for the system. For virtualized servers, a dual-port or quad-port network interface card NIC is recommended for greater connectivity, and a 10 gigabit Gbe NIC boosts performance for environments with an increased number of end users. File servers—sometimes called storage servers or Network Attached Storage NAS —have room for multiple hard drives that protect against data loss in the event of drive failure, a configuration called a RAID array.

They are meant to make available data for a pool of end users. A group of file servers configured together in as Storage Area Network SAN improves data availability across larger networks, and can improve application performance over multiple satellite office networks. Other interfaces for server storage include USB 3. Server cases have different form factors. A MicroServer is a square-ish server box, typically used as a file server or NAS , or a low-power single use server.
