2 Excel Power Distribution Power Distribution Units Power Distribution Units (PDUs) are an important and often overlooked part of an infrastructure design and installation. At their simplest they deliver the power required for the equipment within the rack, more advanced units can provide management information on power consumption and local environmental conditions such as temperature and humidity. It is important to consider the PDU requirement at the rack installation stage rather than as an afterthought at the equipment installation stage. Making sufficient provision for the power will ensure the longevity and best use of the rack. PDUs can be fitted in various different ways within the rack: front; rear; horizontal rack mount; vertical side mount. This may be dependent on Available space in the rack Position of equipment Position of the power input for specific equipment What capacity and how many PDU s should there be? For a rack that will be dedicated for equipment consideration should be made for dual power supply. In this case at least two PDUs will be required to provide the primary and secondary power supplies. This is typical for data centre and high importance communication rooms. Where racks are used to serve smaller locations and house a mixture of equipment and cabling then the requirement may be less. However, as networks and installations evolve over time the requirements change. There are a variety of types of sockets including IEC C13 & C19 type used throughout the world. Additionally there are country specific types, such as the UK (BS1363), Schuko and NFC French styles. Excel has Standard, Modular, Monitored and Managed PDUs to suit all requirements. Efficiency Measurements The more energy that is used in a data centre (or other facility) results in higher bills. These account for major ongoing costs in operation. Efficiency measurements are required to establish the performance of the data centre. Depending on the organisation or current trends these can be carried out in many different ways. The following two make the same comparison, just expressed in different ways. Power Usage Effectiveness Power Usage Effectiveness (PUE) compares the energy used directly for the computer equipment with the total power used in the facility. The calculation is a simple formula: Total Facility Energy PUE = IT Equipment Energy Total Facility Energy is a measure of all energy used including that consumed by the IT equipment. This includes, measuring the energy consumed as electricity, gas etc. IT Equipment Energy only relates to the energy used for the direction operation of the equipment. All energy measurements must be in the same units (or converted), for example kwh (kilowatt hours). The resulting number does not have units. The aim is to reduce the PUE, with a PUE of 1 meaning only the IT Equipment uses energy. The typical PUE is difficult to quantify. However, the aim should always to be below 2. Data Centre Infrastructure Efficiency Data Centre Infrastructure Efficiency (DCIE) is the inverse of PUE and is expressed as a percentage. Therefore the formula is: IT Equipment Energy DCIE = Total Facility Energy Using and recording the information that is supplied from the Excel Intelligent PDUs can help calculate the IT Equipment Energy usage, which in turn allows the PUE or DCIE to be calculated. Once the baseline figure is calculated steps can be put in place and the improvements may be measured. 154

3 Excel Modular PDU Range The Excel range of modular PDU s introduce flexibility and design options to suit your power requirements. A range of socket modules are available which snap into the housing quickly, easily and securely without the need for tooling. First choose the empty housing hardware: Part Number No. of Modules Housed Input Connectivity Output Connectivity Voltage Current Rating (Amps) Optional 250V 32A Optional 250V 16A Optional 250V 13A Optional 250V 32A Optional 250V 16A Optional 250V 13A Then pick your choice of power modules to go into your chosen housing. You can mix and match socket styles to suit your requirements and be safe in the knowledge that you can change them at a future date with the snap in connectivity. The Excel power modules may be added or removed safely without turning the power off. Installations of modular housing with empty positions is safe and makes provision for future power requirements without having to commit to the socket connectivity. See below for the list of modules available.

4 Excel Power Distribution Excel Standard PDUs The Excel Standard PDUs are available in a variety of sizes and socket types. The horizontal PDUs have the mounting brackets at the front to allow attachment to the 19 profiles. The vertical PDUs have the mounting brackets at the rear to allow mounting to single 19 profile, side supports or flat surface. Note that vertical PDU s are sometimes referred to as Zero U, due to mounting outside of the vertical equipment mounting rails. A range of input connectivity plugs are available to support different installation environments. The IEC Commando style plugs are utilised in Data Centres and other locations where the total current load for the PDU will exceed the standard domestic plug rating (UK BS1363, Schuko, French NFC. etc). It is becoming more common in rack installations to use either the C13 or C19 IEC output sockets. Within the range there are also PDUs with C14 and C20 Input Plugs so that a PDU may be connected direct to a rack mounted UPS (Uninterruptible power supply).

6 Excel Power Distribution Excel Intelligent PDU Family The Excel Intelligent PDU Family offers a high specification portfolio of power distribution units that are designed to suit any environment, where monitoring or managing of information is required. Excel is able to offer a PDU with up to 48 sockets with any combination of socket type including UK, Schuko, C13, C19 etc. We design and build everything in the UK, and have developed a wide range of products that cover the whole scale from overall monitored products to individual socket monitoring and individual socket switching. With a turnaround of approx days from order to manufacture and delivery, the Excel Intelligent PDU range provides total flexibility to allow you to build a solution that fits your individual requirement. From our experience there isn t an Intelligent PDU of one size fits all so we provide you with a simple build configuration to get exactly what you need. Our range of products has been developed so they can work as individual masters or run as a master and slave system. We can have one master with up to 31 slaves, all from one IP address, reducing the requirement for multiple IP addresses. The Excel Intelligent PDU range also comes with free software making it a highly competitive solution allowing the user to monitor and report on up to 50 IP addresses with the software. In theory it is possible to have up to 1600 PDU s each with up to 48 outlets per PDU, all from one free software licence. The Excel Intelligent PDU range provides billing quality accuracy to better than 1%, allowing the unit to be used in co-location centres for the monitoring and charging of power used. Our system is designed for use in both single and 3 phase systems and to that end is designed with one monitoring board, but with a meter board at the beginning where the input power flows through, allowing them to sample the power 4000 times per second. This enables the units to measure the power at every point on the sine wave providing a very accurate result. Most Intelligent PDUs available only sample between 200 and 250 volts, so results are not as accurate, particularly with RMS voltages. The meter board allows the unit to economically meter a 3 phase system, as it uses 3 meter boards, one per phase. If required the PDU can be split into 3 separate sections (for use in co-location facilities) and group the results for 3 separate users on the same power strip. Other possibilities are to measure both A and B feeds through one monitoring system. 158

9 Excel Intelligent PDU Family Communications Protocol s The Excel Intelligent PDU has embedded HTML web pages, which can be viewed as either HTTP or the more secure HTTPs. The web pages allow a user to Monitor and control the power usage of a PDU, as well as providing the interface to set up the PDU and commission it for use. The PDU can also communicate via SNMP V1, 2, and 3, enabling the user to integrate the PDU s with their own software choice using a MIB file. RGB Display As standard the PDU comes with a built in RGB Display, the display shows IP Address, kwh, and Volts, Amps, power factor and kilowatts per phase. In the event of an alarm condition the display changes colour and flashes giving a visual representation of a problem. An optional remote display can be fitted to the rack door or in a prominent position where the inbuilt display may be obscured at the rear of a rack.
