How to Buy Rack Server: A Guide for Small Businesses
If you are looking for a way to store and manage your data efficiently, securely and cost-effectively, you might want to consider buying a rack server. A rack server is a type of server that is mounted on a metal frame called a rack, which can hold multiple servers and other devices in a vertical arrangement. Rack servers are designed to save space, power and cooling resources, as well as to simplify maintenance and scalability.
But how do you buy rack server that suits your needs and budget? In this article, we will explain what factors you should consider when buying a rack server, such as the size, performance, features and price of the server. We will also give you some tips on how to find the best deals and vendors for rack servers.
What Size of Rack Server Do You Need?
The first thing you need to decide when buying a rack server is the size of the server. Rack servers come in different sizes, measured by the number of rack units (U) they occupy. One rack unit is equal to 1.75 inches of height. The most common sizes of rack servers are 1U, 2U and 4U, but there are also other sizes available.
The size of the rack server determines how much space it takes up in the rack, how many servers you can fit in one rack, and how much power and cooling it consumes. Generally speaking, the smaller the size, the lower the cost and energy consumption, but also the lower the performance and storage capacity. The larger the size, the higher the cost and energy consumption, but also the higher the performance and storage capacity.
Therefore, you need to balance your needs and budget when choosing the size of the rack server. You should also consider how much room you have in your rack and how much room you need for future expansion. If you have limited space or plan to add more servers in the future, you might want to opt for smaller sizes. If you have ample space or do not plan to add more servers in the future, you might want to opt for larger sizes.
What Performance of Rack Server Do You Need?
The next thing you need to decide when buying a rack server is the performance of the server. The performance of the rack server depends on several factors, such as the processor, memory, storage and network of the server. These factors affect how fast and reliable your server can process data and handle requests from your users or applications.
The processor is the brain of the server that executes instructions and calculations. The processor’s speed is measured by its clock rate (GHz) and its number of cores. The higher the clock rate and the number of cores, the faster and more powerful the processor. However, higher clock rates and cores also mean higher power consumption and heat generation.
The memory is the short-term storage of the server that holds data temporarily while it is being processed by the processor. The memory’s size is measured by its capacity (GB) and its speed is measured by its frequency (MHz). The larger and faster the memory, the more data it can store and access quickly. However, larger and faster memory also means higher cost.
The storage is the long-term storage of the server that holds data permanently until it is deleted or overwritten. The storage’s size is measured by its capacity (TB) and its speed is measured by its type (HDD or SSD) and its interface (SATA or SAS). The larger and faster the storage, the more data it can store and retrieve quickly. However, larger and faster storage also means higher cost.
The network is the connection of the server to other devices or networks via cables or wireless signals. The network’s speed is measured by its bandwidth (Mbps or Gbps) and its type (Ethernet or Wi-Fi). The higher
