The Top 5 Things to Keep in Mind When Buying a Server Rack

Server rack enclosures are integral to the success of your organization because they provide the platform that houses the mission-critical tool your enterprise depends on. Selecting the right server rack will help effectively power, cool, and protect your equipment; keep your enterprise running smoothly by reducing potential downtime; and make the management and organization of your datacenter more efficient. Here are five things to consider:

1. select An Appropriately-Sized Rack
Select a server rack with sufficient internal space to house your current tool and ensure that you have ample space to adapt planned hereafter expansion as well as any unplanned tool purchases. Rackmount tool is measured in the Electronic Industries Alliance (Eia) suitable "Rack Units" or Rack "U". One "Rack Unit" is equal to 1.75" in height. Keep in mind that space for accessories, such as environmental monitoring devices, remote power management devices, rack mount Lcd monitors, and battery back-up, may be necessary. For example, if you need to adapt 20 2U servers, you would likely want to pick a rack with a height of 44U to adapt accessories such as a 1U patch panel, as well as a 2U Ups back-up battery. A rack’s internal height is measured from the tallest point of any side rail to the lowest chassis; internal depth is measured from the insides of both front and rear doors; and internal width is measured from one side panel to the other. Be sure that the rack’s external dimensions can be accommodated in the floor space allotted for it, check that it can be safely moved through all doorways, and ensure that its placement meets any relevant clearance or protection regulations. As a note, always use suitable rack-loading techniques, including placing heavy items at the lowest of the rack to preclude a rack from becoming too top-heavy, have a plan about what you want to put toward the front and back of the rack (based on how much you will need to way or take off equipment), and have man help load tool that is heavy and/or above the height of your head. (1)

2. Corporeal protection Starts Here
Proper protection is vital to the allinclusive well-being and the function of your business. Knowing how your server rack fits into your allinclusive protection strategy is just as important. There are some measures you can take to heighten the protection of the racks and tool in your datacenter. To begin with, consider purchasing server racks that have locking front and rear doors, as many models offer this option. Second, use environmental monitoring devices to proactively monitor your racks. In addition to allowing administrators to continuously monitor amperage draw per circuit, water leaks, temperature, and other variables, and sending alerts automatically via Smtp/Sms/Snmp when conditions exceed established thresholds, some environmental monitoring devices have door sensors that sustain “normally open” or “normally closed” conditions and can alert administrators when a cabinet door has been opened. (When a change in state relative to its defined threshold occurs, the gismo reports an “error” condition.) In addition, there are devices available that work with docked camera pods and sensor pods to allow administrators to continually visually monitor server racks and rooms, as well as record audio clips. If you are planning a new datacenter, you might also consider additional Corporeal protection measures such as building the datacenter away from a main road, limiting windows in the datacenter, and providing collect entrances and exists. (2)

3. Tailor Your Rack produce To Work For You
Most manufacturers will allow you to select from many options so that your server rack meets the definite requirements of your environment. There are some base areas that you should be able to select options from.

Shelving: Most manufacturers offer some server rack shelf options, including adjustable or fixed server shelves with four-point mounting; sliding keyboard shelves with 2-point mounting; vented, heavy-duty, or cantilever shelves; and media shelves. pick a server rack shelf with a depth of 6 inches less than the allinclusive depth of the rack—for example, if you have a 30-inch deep cabinet, pick a shelf with a depth of 24 inches.

Top and Side Panels: Top panels protect tool from foreign materials. Options comprise perforated slots for added ventilation, grommet holes for additional cable management pathways, and mounting for exhaust fans. Side panels offer protection and are often available in some options: solid fixed, solid removable, and solid with vents (louvered).

Mounting Rails: Most racks come with two sets of mounting rails. However, additional sets of rails can be ordered to adapt dissimilar depths and facilitate rack loading. Most manufacturers allow you to pick from Universal Mounting Rails (square holes fitted with cage nuts) or Eia suitable rails (with 10/32 tapped holes). Universal rails will sustain 19" Eia width rackmount and networking tool and approximately all server equipment. Eia suitable Mounting Rails sustain 19" Eia width rackmount and networking tool and some server manufacturers’ rack mounting equipment. Either the rails have quadrilateral or tapped holes, all mounting rails comply with the Ansi/Eia-310-D suitable (1992). Most major enclosure manufacturers suggest rails with quadrilateral holes and cage nuts, and currently most off-the-shelf rack models apply rails with quadrilateral holes.

Feet: available “feet” options comprise retractable anti-tip feet to stabilize mid-to top-heavy loaded racks; casters that attach to the lowest of server cabinets to help maneuver racks; and levelers that should be used if casters are implemented to ensure that the rack remains level once it has been moved from one place to another.

4. consider The most recent Power Technologies
Power Distribution Units (Pdus) evenly disperse power to servers over the entire power strip. Rack mount power strips are specifically made for server racks and mount vertically or behind mounting posts in the back quantum of a cabinet. Power strips fall into two categories: suitable and intelligent. While suitable power strips have some features that can provide needful information, such as fuse exchange indicators and current output displays, they must be managed in-person and on-site. In contrast, bright power strips provide remote power control, which allows administrators to achieve a cold reboot of servers and devices and troubleshoot problems from any location with an internet connection, reducing server downtime and getting vital enterprise functions back online quickly. Remote power products not only provide bright operate of attached systems, they also allow administrators to leverage leading advances in power distribution, such as 3-Phase power. Three-Phase power technology is not exclusive to remote power management products, but many solutions can adapt or incorporate it. Compared to single-phase power, 3-Phase power uses fewer circuits, provides a more balanced power load, reduces the allinclusive whole of Pdus needed to power equipment, and significantly increases available amperage into the server rack. As an example, in a traditional rack environment, (4) 20-amp circuits would be required for 64 amps of available power (assuming a maximum 80% load). In contrast, a 3-phase circuit can provide up to 51.6 amps per circuit, or more than 82 amps of available power, while only requiring 2 circuits (assuming a maximum 80% load). The cost savings of 3-Phase power is beneficial, especially since experts estimation that in the future, electricity costs could rise from current levels of 10 percent or less of It budgets to 20-30 percent (3). Other power-related aspects to keep in mind comprise the whole of outlets you will need, plug/receptacle requirements, and redundancy requirements.

5. Know Your Cooling Strategy
Understand the role that server racks play in your perfect data center cooling strategy. The type of rack you pick will depend on the cooling methods used in your environment. Baseline kW of heat output per rack varies widely, depending on type and density of equipment, and can be in any place from 4 kW-12 kW or more per rack, with some experts estimating that the rise of high-density environments and designs for hereafter tool will succeed in an output of 30-50 kW per rack. (4)

Fully Perforated Racks: select a fully perforated rack for maximum air flow if the traditional method of cooling in your datacenter or server room will be ambient air cooling (fans, air handlers, blowers, and/or Computer Room Air Conditioning (Crac) units and a raised floor).

Fully-Sealed Racks: pick a fully-sealed rack if a liquid cooling unit or rack air conditioner will be used in your environment.

As power-intensive applications and server densities have increased, Liquid Cooling Units (modular, temperature-neutral high-density cooling solutions that apply air/water heat exchangers to provide uniform, productive cooling) are increasingly being used. One of the main benefits of self-contained liquid cooling units is that they succeed in petite or no impact on the existing Hvac system. Liquid cooling units are mounted at the rack base, in a rack “side car” with three cooling modules potential per tool rack, and can provide a total cooling capacity of 30kW.

Rack air conditioners are generally not used in traditional datacenter environments that have sufficient Crac systems. However, if It tool will be placed surface of a controlled datacenter environment, such as in a storage or factory, rack air conditioners are sometimes used. It is leading to keep in mind that rack air conditioners are intended for use in market and large spaces, they originate condensation and noise, and they exhaust hot air into the room where the enclosure is located. In a large room, the heat will dissipate. In a smaller room or confined space like a closet, the exhausted hot air from the Ac unit can cause the room to overheat. If an Ac unit is used in a small room, measures must be implemented to exhaust the hot air from the room. Air conditioner models differ in the whole of cooling output they can provide, so select one suitable to your needs.

Below are formulas to help imagine heat load and select a rack air conditioner:
1. Add up the wattage of each gismo and change it to Btu (a device’s manual commonly lists its wattage). You can also resolve wattage with the following method (Watts=Volts X Amps).(5) Remember that 1,000 Watts=1kW.

2. If a rack air conditioner will be used, for every 1 kW consumed, consider that 3412.14 Btu is generated. Air conditioners are rated for dissimilar Btu levels.

Additional Tips
Other ways to heighten cooling comprise using blanking panels to conduct air flow efficiency, Selecting a rack with built-in channels for better cable management and improved air flow, and removing any obsolete or unnecessary tool from the rack. In addition, consider that 3-phase power can significantly increase available amperage into the server rack, reducing the
overall whole of Pdus needed to power tool and leaving more space for airflow.
