Finding the Ideal Server: Key Considerations and Tips

After understanding the various types of servers, the wide range of options can make it challenging for buyers to decide. This section outlines some principles or factors to help buyers choose the most suitable server.

Stability Principle

Stability is the most crucial aspect of a server. To ensure the normal operation of the network, it is essential to guarantee the stable running of the server. If the server fails to operate correctly, it can result in irreparable losses.

Specificity Principle

Different network services have varying requirements for server configurations. For instance, file servers, FTP servers, and video-on-demand servers require large memory, high-capacity, and high read-rate disks, as well as sufficient network bandwidth, but do not need high CPU clock speeds. Conversely, database servers require high-performance CPUs and large memory, preferably with a multi-CPU architecture, but do not have high demands for hard disk capacity.

Web servers also require large memory but do not need high disk capacity or CPU clock speeds. Therefore, users should choose server configurations based on the specific network applications they intend to use.

Miniaturisation Principle

Except for providing advanced network services that necessitate high-performance servers, it is advisable not to purchase high-performance servers just to host all services on a single server. Firstly, higher-performance servers are more expensive and offer lower cost-effectiveness. Secondly, despite a certain level of stability, if a server fails, it will disrupt all services. Thirdly, when multiple services experience high concurrent access, it can significantly affect response speed and even cause system crashes.

Therefore, it is recommended to configure different servers for different network services to distribute access pressure. Alternatively, purchasing several lower-spec servers and using load balancing or clustering can meet network service needs, saving on costs while greatly improving network stability.

Sufficiency Principle

Server configurations are continually improving, and prices are constantly decreasing. Therefore, it is essential to meet current service needs with a slightly forward-looking approach. When existing servers can no longer meet network demands, they can be repurposed for services with lower performance requirements (such as DNS or FTP servers), appropriately expanded, or used in a cluster to enhance performance. New servers can then be purchased for new network needs.

Rack Principle

When a network requires multiple servers, it is advisable to consider rack-mounted servers. Rack-mounted servers can be uniformly installed in standard cabinets, reducing space occupancy and eliminating the need for multiple monitors and keyboards. More importantly, they facilitate power management and clustering operations.

Conclusion

Choosing the right server architecture is a strategic decision tailored to specific needs. Each type of server has its advantages and disadvantages, depending on an organisation’s particular circumstances and goals. In practice, some organisations opt for a hybrid deployment, utilising different server architectures based on workload requirements. This hybrid model can maximise the strengths of various architectures, providing more flexible solutions. We hope this article helps readers gain a comprehensive understanding of different server types to better meet their business needs.

How to Manage Cables in Server Rack?

Posted on August 4, 2018 by Admin

In data centers, we run all enterprise network equipment (server, storage, network switch, etc.) into the server rack. And various wires such as fiber optic cables, Ca5e/6 Ethernet cables and power cords are spreading all over the floor. It’s rather a disaster to see all these cables tangling together without knowing which ends they are tracing to, which is inconvenient for operators to implement troubleshooting. Besides, interwined wires also cause cooling problem, crosstalk and interference, which causes performance issues. Fragile fibers under neglected management will easily break. All these reasons confirmed the necessity of proper cable management. So how to manage cables in server rack?

Figure 1: An array of cable management accessories are installed in open server racks to manage cables.

Deploy Proper Server Rack

Above all, estimate your enterprise network scale, cabling numbers and other requirements to choose proper server rack. There are mainly three types of server cabinets in the market, making sure to choose the one for your network environment. All these server racks price are competitive in FS.COM.

Open Frame Server Rack

The open frame rack has no sides and doors to restrict it from reaching the open air. It provides easy access, sufficient open space and airflow for cable management, ideal for high-density cabling for server room and data center racks. You’d better to use open server rack in applications that don’t require security protection for cables. 2-post and 4-post are two types of open frame racks. The former requires less depth whereas the latter supports more weight.

Enclosed Server Rack

The enclosed server rack is a sever cabinet with front and back doors and side panels. The doors can be locked to prevent intentional sabotage and dust invasion. Black server rack 42U/45U is available in FS.COM to offer you with abundant rack cabling space. FS elaborately designs efficient brush guards on the roof to facilitate airflow and ensure better cooling.

Wall Mount Server Rack

Wall mount server rack is used to hold network equipment such as network switch and network accessories such as fiber patch panel. It features functionality to be attached onto the wall to save floor space. FS manufactures 9U/12U 4-post wall mount network cabinets with glass front door. The defect is that wall mount server rack is not as big as other server racks to room large quantity of network devices. In this case bigger network cabinet is the better choice to go. Here is a comprehensive data center cabling solution video guide for your reference.

Deploy Other Cable Management Products in Server Rack

After choosing optimal server racks for your cabling solution, take other cable management accessories into consideration.

Deploy right fiber patch panels or cassettes to terminate your fibers, and use matching fiber enclosures to load them and other enclosure accessories such as fiber slack management spool. An intact loaded fiber enclosure ensures safe entry and exist of fiber patch cables and stores an excess of fibers in a compact of 1U/2U/4U.

Use cable organizer – horizontal cable manager and vertical cable manager to keep scattered running cables in right place and ensure a neat rack environment. Besides, employ cable ties/zip ties to fix wire bundles.

Put emphasis on cable identification tools. Cable ties are available with different colors to help figure different types cables or end devices. Color coded fibers and Ethernet cables are also helpful for recognition. Or you can buy color-coded cable labels with different numbers to mark your wires.

Conclusion

Proper cable management cannot be accomplished in one action. First of all, carefully plan your cabling solution on the basis of your data center scale. Then deploying proper server racks or cabinets and other cable management products – fiber enclosure, fiber patch panel, cable organizer/cable manager, cable ties, cable labels to manage cables shipshape and facilitate cable identification. All these jobs done orderly will make a clean and decent server room, and endow cables and the whole systems with security warranty.
