The Three-Phase power technology for server racks is not very exclusive to operating remote power management products. Actually, there are several solutions that can be accommodated by this technology. When you compare it to a single-phase power, it utilizes a fewer circuits making electricity in power loading more balanced. It also decreases the number of needed PDUs in order to power an equipment. It can also significantly reduce the amperage being used inside the server rack.
To further explain on this topic, there is a traditional rack environment that has 20-amp circuits that is going to be required to provide 64 amps of available power. Assuming the maximum power load of about 80%. In a contrasting scenario, the 3-phase circuit can give power up to 51.6 amps per circuit. That is equivalent to 82 amps of available power. It will only require 2 circuits in order to accommodate the 80% load.
The cost-efficiency required in order to run a 3-Phase power is very important. The electricity experts have an estimation that in the near future, the cost to acquire electricity (compared to recent costs) has the possibility to rise 10%. When it comes to IT budgets it can get to 20-30%.
The other electricity or power related required aspects should include the number of outlets that the server rack will be needing. Including the plug/receptacle requirements as well as the redundancy requirements.
When it comes to selecting a server rack with the appropriate, sufficient internal space to be able to accommodate your equipment is needed. Also it ensures that the server rack has ample space to house the equipment that will be needed for future expansions. Especially when there are unplanned purchases of additional equipment.
The server rack mount equipment is being measured using the Electronic Industries Alliance (EIA) standards. The standard measurement is one “Rack Unit” has the equivalence of 1.75” in height. Always be aware that the available space for accessories – the environmental monitoring devices, remote power management devices, LCD monitors and battery back-up – might be important.
With this example, if an engineer needs to accommodate at least 20 2U rack servers, they are more likely to buy a server rack with a height of 44U in able for them to accommodate all the needed accessories. These can be the 1U patch panel, as well as the 2U UPS battery back-up. The internal height of the server rack is being measured by getting the measurements from the tallest point of any side of the rack server up to the bottom of the chassis. The internal depth that is being measured internally are being done on front and rear doors. In addition to this, the internal width is being measured from the other side of the panel to the other.
