Rack Mount Shelves and Brackets

A range of rack mount shelves and brackets for use in server racks and cabinets including L-brackets, fixed, telescopic, modem and adjustable shelves. It is important when choosing rack mount shelves to ensure the depth of the shelf is matched to the cabinet depth and allows for cable runs and other clearances you may require in when populating your rack or cabinet.

Orion Rack Mount Shelf Guide

This is a general guide for selecting shelves for server cabinets and server racks.

Shelf Type	Mounting	Universal	Note
Fixed shelves	Front and rear	No	Designed for Orion racks and cabinets and are not guaranteed to fit other manufacturers cabinets
Telescopic shelves	Front and rear	No	Designed for Orion racks and cabinets and are not guaranteed to fit other manufacturers cabinets
Model shelves	Front mounted only	Yes	Will fit into most 19inch server cabinets
Adjustable shelves	Front and rear	Yes	Will fit into most 19inch server cabinets

Matching Shelf and Server Cabinet Depths

Cabinet Type	Range	Depth Note
Floor Standing	VS (Value) / FS (Floor Standing) / Premium (SR)	The usable depth is 130mm less than the overall cabinet depth
Accoustic	AR (Acoustic) / ARM (Mini Acoustic) / Tranquillo (TAR)	The usable depth is 180mm less than the overall depth
Wall Mounted	WM (Wall Mounted)	The usable depth is 100mm less than the external depth

For example for a 600mm deep foor standing cabinet the usable depth is 130mm deeper = 470mm and then you should allow for any further room you require for cables to run down the back of the cabinet.

Server racks are designed for one purpose and that is to provide an easy and secure way to house IT servers and their associated networking devices. Most organisations will have at least one server rack and the problem for many today is how to expand their existing installation to take advantage of new server technologies.

Data centres and server rooms should be designed around the workload they have to support both from day-one and in the future. This is not always the case and many server room operations evolve from their initial concept, driven by changes in demands, workloads and technology. This can lead to inefficiencies and less than optimum design in terms of critical systems and resilience.

How you manage the air flow within your server racks can have a dramatic effect on the overall energy efficiency of your datacentre and specifically the server room area. The higher the temperature within the server space, the greater the need for cool air from your air conditioning system and its delivery to your server racks either via a raised access floor or general movement via fans within the room. The harder the air conditioning system must work, the greater the energy used and the higher the running costs in terms of electricity bills.

A server rack is a frame into which 19inch rackmount servers, storage and associated networking devices are mounted or ‘rack mounted’. The frame may be 2 or 4-pillar in design. Equipment suitable for a server rack is termed ‘rack mount’ or designed for ‘rack mounting’. A server rack with side panels and a front and rear door assembly can be called a server cabinet. The front door may be solid metal, perforated hex mesh or glass. The rear door is typically solid or perforated hex mesh. The doors and side panels do not just make the server cabinet more secure but also assist air flow management. Server racks and cabinets are defined by their height in ‘U’ where 1U=45mm and their width and depth with typical sizes being 600, 800, 1000 and 1200mm.

If your cabinets are only partially populated and has perforated ventilation holes in the front and rear, you may not need additional cooling fan kits. Server manufacturers typically recommend a minimum perforation factor for the doors of the cabinets that would be used to house their servers and this is typically from 63% upwards; to allow adequate air flow from front to rear.

Server racks are designed for front air intake and rear cabinet exit. Cool or air conditioned air should be drawn into the front of the rack by fans within the servers themselves or within the server racks and this then exits as warm air out of the rear of the cabinet. In a data hall server racks are typically positioned in rows and the rows positioned so that the fronts face each to optimise cool air and hot air flows. This is a basic for of hot-aisle/cold-aisle containment. The server racks may themselves be within a separate containment known as a hot-aisle/cold-aisle container. For some server racks we can also offer rear cooling doors to help collect the hot exhaust air. The cooling doors fit onto the rear of the cabinets and use chilled water pipes within the rear door. We can also supply additional cabinet fans for extra cooling capacity.

We have over 30 years of experience working within data centre and server room environments. Our knowledge and experience means that we know how to design, install and maintain the right cooling, energy management, power and monitoring solutions for any critical IT environment.
