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 – l Available space in the rack l Position of equipment l Position of the power input for specific equipment

What capacity and how many PDUs 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:

PUE =

Total Facility Energy 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:

DCIE =

IT Equipment Energy 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.

2. 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.

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 PDUs 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 60309 “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).

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 10-14 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. however we can offer the Lite version off the shelf. Our range of intelligent 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.

S9

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. The Lite range are produced using a Neutrik connector, for the power cord, allowing the PDU to be adaptable for any environment.

164


www.excel-networking.com The Excel Intelligent PDU range is a highly flexible solution. All versions have a built-in Environmental centre which covers a series of functions. As standard the units have a local display which can be supplemented by an additional remote display that can be mounted on the front of a rack for easy reading.

Communications Protocols iPower PDUs can communicate using multiple methods, via web browser utilising the embedded web pages, these give you full access to all PDU functionality, enable the setup and configuring of the PDU, enable the user to view live data, set thresholds, and view alerts on Single and Multiple PDUs, SNMP, using our MiB file a customer can upload onto their own or third party software, this can be used to gather information, view live data, control PDUs and collate information and histrionics.

Linking iPDUs PDU’s can be linked together with RJ22 to RJ45 communication cables by simple daisy-chain interconnections through 3-way splitters utilising 2 wire RS485 interface. This allows the construction of a network of PDU’s, where the 1st PDU becomes the master and subsequent PDU’s are set to “slave” mode, up to a maximum of 1600.

When daisy chaining the units the following items are needed: IPT-500-553 (3 metre cable RJ45 to RJ22) or IPT-500-555 (5 metre cable RJ45 to RJ22)

S9

And:- IPT-500-500 (RJ45/RJ22 3 way connector)

Std Cat 5e Patch cable from Ethernet port to PC or ther device

Central Management Our own Application software SNMP PDU Agent is a free to use application software aimed at a small to medium installations where a full DCiM platform is not required, it can be installed on a local PC, this can talk to up to 50 IP Addresses, 1600 PDUs (Daisy Chained), and provide Full control and Monitoring, Creation of Thresholds and Alerts, Data and Event Logging, Graphical Information and a complete user interface. The PDUs also have the ability to communicate using XML and Telnet, Telnet again offers full control over the PDUs functionality and is ideally suited to the home automation market.

167


Excel Power Distribution Sensors To complement the PDU’s and create an environmental solution, there is a host of sensor options available for the system*. Some of these items:l Temperature Sensor – Up to 8 Temperature sensors can be connected to the PDU, via a dedicated Port. l Humidity / Temperature Sensor – A single combined Temperature and Humidity sensor can be connected to the PDU via

a dedicated port.

l Smoke, Fire, Water, Heat, + Any type of Sensor with a normally closed relay output can be connected to the any one of

the 3 sets of Voltage free contacts on the PDU (Not IPLite)

l Remote Display – A slave / remote display can be connected to the PDU for mounting elsewhere within the cabinet,

Door, Plinth etc. for ease of viewing cabinet status.

l Door Locks – Electronic Door Handles with a 12 VDC operating mechanism can be connected to the PDU, other voltages

can be connected but require additional hardware. (Not IPLite)

l Door Contacts – Door contacts can be connected to the PDU to provide alerts when a cabinet door is opened. (Not IPLite) l Keypads / Readers – The PDU also has a dedicated port for Wiegand 26 capable readers / pin pads. (Not IPLite)

*Some of these items are 3rd party technology, and this section is designed to show the capabilities available.

S9 Billing Quality The Intelligent PDUs provide a high level of accuracy to help plan capacity and also provide accurate costs for billing purposes, the Class II billing quality meter circuitry utilises a calibrated resistor, this is more accurate than current transformers used by some manufacturers and due to the current being drawn directly through the resister means that we can accurately measure the full AC waveform from Peak to Peak providing extremely accurate measurement of RMS Volts, RMS Amps, Power Factor, the accurate measurement of Power factor means we can correctly report values for Kilowatts and Kilowatt Hours, making billing and capacity planning straightforward, this along with other values of Peak Volts, Peak Amps, kVA, BTUs, Energy Cost and Kilograms of CO2. The unit can also be calibrated onsite to further improve accuracy, subject to extra costs and availability.

Warranty Excel offers a 5 year return to base guarantee on all there main line products, whereby the product will either be repaired or replaced at the manufacturers discretion. On being notified of a problem of an apparently defective product Excel reserves the right to send an engineer to site (if economically viable to evaluate the problem.) prior to the return. Products containing surge suppression items are limited to a 2 year return to base warranty. Products which have been abused, damaged or not used for their designated purpose are excluded from any warranty.
