Complete Guide to Buying Server Rack Shelves

There is a huge variety of hardware that can be mounted in server racks, and there are also a wide variety of methods in which this hardware may be mounted. If you want to make use of server rack shelves, you should search for the most cost-effective solutions that are suitable for your requirements. 

To make the best purchase decisions, you'll need to know a lot of things, like when a sliding shelf may be better than a fixed shelf and when it's okay to put a two-post shelf inside a four-post rack.

In what circumstances might 2 post shelves be used in place of 4 post racks? 

People often buy server rack shelves in order to store almost all of their equipment that is not related to servers. This means that they have to be able to hold a wide range of equipment, both in terms of size and weight.

Even though it could make sense to purchase a 4-post shelf given that you already have a 4-post rack, the vast majority of 4-post racks are designed to accommodate the majority of 2-post shelves. Purchasing the appropriate number of two-post shelves for your four-post rack will help lower the weight on your rack, increase the quantity of air that your equipment is exposed to, save you money, and minimize the amount of resources you consume. 

You should begin by determining whether or not your rack has two mounting points on each upright. If it does, then you may go on to the next step. Mounting hardware for 4-post racks often only has a single point of attachment per post, while mounting hardware for 2 post racks typically has two points of attachment per post.

If your rack has two points of connection, then the majority of shelves that are 2 posts tall will work with it. If there is just one point of connection, then the alternatives available to you will be constrained.

For instance, due to the fact that it has one connection per upright, the 2 Post Rack Sliding Half Shelf that Rack Solutions offers would be a breeze to install on any 2 post or 4 post rack. On the other hand, to mount a Rack Solutions Fixed Rack Shelf on a 2-post shelf, it would need two points of connection because it can hold more weight.

During the design process, making a decision on a server rack frame can be the single most crucial step. In order to aid you in selecting a rack that is an appropriate match for your environment, the following are eight things to keep in mind:

  1. For the rack cabinet enclosure, what size should I get?

The kind of hardware that must have rack mount capabilities as well as the quantity of hardware that must have server rack enclosure space are the two primary considerations that go into determining the appropriate size of the server cabinet. Planning is essential in order to have a successful experience while purchasing a server rack. Because cabinet rack units cannot be put on after a server rack has been manufactured, it is ideal for users to tally the entire quantity of rack units that are now required while also taking into consideration any potential future growth. In the event that additional rack mount accessories are needed, such as environmental monitoring, battery back-up, and/or remote power management, additional front and rear cabinet space may be required in order to adequately mount rack accessories both vertically and horizontally. This is because mounting rack accessories requires a certain amount of depth. Racks may be selected according to size by clicking this link.

  1. Why is it important to have accurate measurements for the inside rack cabinet enclosure?

When determining the size of the equipment and the number of pieces that can be stored in server rack enclosures, it is important to utilise the internal dimensions as a reference. Total internal height is determined by taking vertical interior measures beginning at the highest point of any side rail and ending at the bottom of the chassis. To determine the internal depth of a space, one measures from the inside of both the front and the back door. Last but not least, measurements of the inside width are taken from one side panel to the other.

When assessing rack mount requirements, it is important to obtain interior dimension measurements that take into account rack equipment and accessories that are often mounted internally to the back or side of cabinets. During the production process of racks, additional space may be adjusted to allow for the mounting of rack equipment on the side, back, or front of the rack. Also, the space set aside for the auxiliary compartment will have room for ventilation systems, power lines that are hard to manage, and other needs.

  1. Why is it important to have accurate measurements for the external rack cabinet enclosure?

It is common practice to wait until the rack enclosure has arrived at the dock for delivery before determining the position of the server rack inside the data center or co-location facility in which it will be housed. It is of the utmost importance for users to discover whether or not the finished precise exterior dimensions of the server rack will be able to pass through doors and other barriers of the planned target site. When designing the environment of your data center or server farm, give careful consideration to environmental issues such as ceiling height and clearance standards. If server racks need to be moved via stairways or freight elevators in order to reach their ultimate installation, be sure that the dimensions of these passageways are respected.

  1. Will the space that my rack cabinet enclosure is meant for be able to accommodate it?

When transferring server racks from one location to another, it is very crucial to take into consideration a variety of parameters, including the weight and height of the server rack. Certain kinds of server racks may weigh more than 300 pounds and stand more than 7 feet tall at their maximum height. Since server racks are enormous things, moving them, turning corners, carrying them up stairs, and squeezing them into any kind of confined space requires a significant amount of work. Before you decide to buy rack enclosures, you need to make sure that there is enough space and that it has been taken into account.

  1. Will the Rack Cabinet Enclosure be able to pass through any and all of the doors on the way into the destination room?

Each and every one of our server rack enclosures ships pre-built and ready to use. There are certain components that may be removed, such as the door and the side panels; however, this will not affect the rack's outward dimensions, and the frame itself cannot be disassembled. If you want to make sure that your server racks meet all clearance rules, you should carefully look over all product measurements.

  1. Can you explain what a rack unit is? What exactly does 40U stand for? 44U? 48U? etc.

An EIA standard allowance unit for measuring rack mount equipment is referred to as a "Rack Unit," sometimes abbreviated as a "Rack U." One "rack unit" is equivalent to a height of 1.75 inches. To get the amount of internal space that may be used inside a rack enclosure, just multiply the total number of rack units by 1.75 inches. For illustration purposes, a 44U rack enclosure would have 77 inches of usable interior space (44 x 1.75). To choose racks based on their height, click here.

  1. How can I determine how many rack units I need and how to compute that number?

Many administrators of data centers compute the required height of rack enclosures by first evaluating the best possible use of rack units. Users, for instance, who are aware that future plans call for the installation of 20 servers with a size of 2U might reasonably anticipate that they will need a rack enclosure with 44U of space. This will provide sufficient interior height for about twenty servers, as well as space for a one-unit patch panel and a two-unit UPS back-up battery. There will be enough room on the back or side of the vehicle for vertically placed power management devices to do their jobs.

  1. What is the function of a relay rack with two posts?

A relay rack is a two-post structure made of aluminum or steel with either EIA standard mounting holes (round) or universal mounting holes (square). The mounting holes may be either round or square. Racks for relays are also sometimes referred to as 2-Post Racks or Open Bay Racks. Mounting telecommunications or computer and network equipment requires a certain vertical hole spacing, which is defined on relay racks. Cantilever shelving for different types of equipment that cannot be mounted on a rack may be attached to Relay Racks. As a result of the open frame architecture, the Open Bay rack design allows for the greatest possible movement of air across the whole rack.

How to Determine If You Need Sliding Shelves or Fixed Shelves

Here are some considerations you should ask yourself before determining whether to use sliding or fixed shelves: 

  • How often will it be necessary for me to access the wires that are located at the rear of the shelf? 
  •  At what intervals would it be necessary for me to take apart the machinery or conduct maintenance? 
  •  Will a feature that slides make it possible for me to reach the equipment with more ease? 
  •  How important is it that the product be easy to use?
  •  What is the maximum amount of weight I can carry? 

There’s really much to get around it. Sliding shelves are always going to be the prettier product. Therefore, the majority of the choices depend on how much money you have available and how big of an impact having easy access to equipment may have on your productivity. 

The only time this is not true is if you have a need for a very high weight capacity. When compared to a sliding shelf, a fixed shelf will often have a larger weight capacity ceiling than its sliding counterpart. If the weight capabilities are the same, the sliding shelf will almost certainly have a higher price tag if it is constructed with the same level of quality. 

When could rails be more appropriate than rack shelves to use instead? 

It is natural to believe that shelving is the ideal choice for mounting equipment that does not have a special mounting solution and that equipment will be placed in the same location for an extended period of time. This is true most of the time, but there may sometimes be another approach that is less expensive. 

Universal Rack Rails are simply shelves with L-shaped hinges that hold equipment from both sides rather than having a platform to set stuff on top of. This means they use less material, but it's still easy to take gear off of them.

Because the two brackets do not need to connect in order for you to successfully install these rails, it will not matter what width your rack is in any way. Reducer brackets can also be used to install smaller hardware, like patch panels or switches.
