4 2 Executive Summary ACME Inc engaged Focus Group Technologies to undertake a Data Centre Assessment of their current rack infrastructure located at Harbour MSP. The onsite visit by the engineer had the following observation and recommendations: 2.1 Observations: The current installation is of 3 racks within the Global Switch Data Centre. Overall environmental conditions are excellent as provided by the DC Current Power draw is over utilised above available capacity Operating temperature of racked equipment is within range of ASHRAE guidelines Some efficiencies can still be gained via following data centre best practices 2.2 Recommendation Summary Priority High Impact is High. Action must be taken and be addressed immediately Power utilisation of Racks 1 and 2 are above allocated power. This is currently resulting in excess charges from your service provider. This can be achieved by: o Acquiring additional racks adjacent to the current racks and move some devices in to the new racks. i.e..spread the load across more racks o Or moving the current equipment to rack space that provides more power per rack. With at least % more than measured to account for peaks and growth. Priority Medium Action should be taken and be addressed in the next month or so. Implement environmental monitoring Priority Low Action will result in Best Practice and can be addressed in time. Implement blanking panels in the racks Replace the monitor in Rack 3 with a pull out flip-top LCD monitor. Focus Group Technologies is happy to provide CUSTOMER with a quotation to perform any or all of these services. Focus Group Technologies Pty Ltd. ACN ABN Page 4

5 3 Physical infrastructure 3.1 Quality Racking Server rack cabinets are important to your business success because they provide space for vital equipment that is crucial to the survival of your organization. If you select the right server rack, you will keep your equipment cool, your power running, and your downtime minimized. Racks should be a size and quality that allow for the intended equipment and provide room for cable management and airflow. Observation Quality racks are implemented Recommendation Nil 3.2 Blanking Panels Unused vertical space in rack enclosures creates an unrestricted recycling of hot air that causes equipment to heat up unnecessarily. The use of blanking panels can reduce this problem. Observation Blanking Panels are not implemented Recommendation Implement blanking panels in the racks Focus Group Technologies Pty Ltd. ACN ABN Page 5

6 3.3 Monitors within racks Monitors on shelves create an open space that permits hot exhaust air to return to equipment air intake resulting in overheating. This is a similar effect to not having blanking panels. Observation Monitors on shelves are being used Recommendation Replace the monitor in Rack 3 with a pull out flip-top LCD monitor. 3.4 Cable Management Cable management refers to the process of routing and placing cables within a rack environment. Poor cable management can not only lead to damaged cables or increased time to add or change out cables, but can block critical airflow or access. This can lead to inefficiencies in the performance of your equipment or even downtime Bad cable management Good cable management Observation Cable management was observed to be adequate, some improvements could be made to improve airflow and cable identification. Recommendation Improve cable management by routing cables to the side of the servers. Focus Group Technologies Pty Ltd. ACN ABN Page 6

7 4 Power 4.1 Redundancy of Power to Racks Power to the rack should be provided by dual sources to dual Power Distribution Units (PDUs). Redundant PDUs ensure uptime in the event of issue or failure in the power source, PDU or cabling. Observation Redundant PDUs were implemented. Recommendation Nil 4.2 Redundancy of Power in servers In addition to redundant connections to the individual devices, redundant power supplies should be implemented. Where redundant power supplies do not exist in the device, an Automatic Transfer Switch (ATS) can assist. The ATS is a dual input, rack-mountable power distribution unit (PDU) with a built in automatic transfer switch. The Micro Smart Switch is capable of receiving power from two independent AC power sources and utilises a built-in automatic AC transfer switch to quickly switch between them. This provides AC power line redundancy to critical computer or communications equipment in a rack environment. Observation ATS have not been implemented Recommendation Implement ATS technology for single power supply devices. Focus Group Technologies Pty Ltd. ACN ABN Page 7

8 4.3 Audit of Power Usage ACME Inc engaged Focus Group Technologies to undertake a power audit of their current rack infrastructure located at Harbour MSP. The purpose of this audit is to perform device level analysis of the power consumption so as to determine which devices are consuming what power. In addition, temperature measurements of the rack and surrounding areas were taken. Method As downtime could not occur, out of band external power monitoring was selected as the method of monitoring the power consumption. External monitoring in this case was conducted via a handheld clamp meter on each individual device Accuracy In band monitoring techniques (such as intelligent PDUs, in line power meters) are the most accurate form of measurement, but requires that the equipment is already installed or downtime occurs to place them in the power path. External monitoring in this case was conducted via a handheld clamp meter. The clamp meter has a resolution of 0.1 AMP with a ± 5% error rate. Individual devices or servers were measured at a point in time and those measurements added to provide a rack total. While the total power usage measured per rack will be accurate to within a few amps, more importantly the relative power usage of the devices will be comparable and valuable. The data recorded was a series of point in time measurements of a 2 hour period. As such the data does not represent a maximum or average power utilisation, rather the draw as measured.

10 7 Power Analysis Detail

11 8 Rack Location The diagram below shows the rack locations and orientation within the data centre.

12 9 Temperature Heat Map Floor View This heat map shows the surface temperature of the data centre floor around the racks. The monitored temperature is between 16.4ºC at the front to 21ºC at the rear. Focus Group Technologies Pty Ltd. ACN ABN Page 12

13 10 Temperature Heat Map - Rack Rack Front View ` This heat map shows the surface temperature of the front of the racks. The monitored temperature is between 15.4ºC at the bottom to 26.2ºC at the top left (west) Focus Group Technologies Pty Ltd. ACN ABN Page 13

14 Rack Front View This heat map shows the surface temperature of the rear of the racks. The monitored temperature is between 18.6ºC at the bottom to 32.0ºC at the top right (west) Focus Group Technologies Pty Ltd. ACN ABN Page 14

15 11 Power Observations It is our understanding that the allocated power per rack is 1600Watts. The table below shows the relative power usage versus allocated: Rack Power Usage (W) Allocated (W) % difference % % % Total % Clearly Racks 1 and 2 are over utilised from a power draw perspective, while rack 3 is well within limits. As shown in the analysis detail, no particular single device appears to be a major contributor to the power usage, rather the number and density of the devices. Rack 1 is over drawing the power allocation due to: More devices than the other racks Larger number of high power draw devices (e.g. storage, v245s) The power draw of these racks is well within current industry norms (usually 16 or 32 amps per rack). A concentration of high power draw equipment also results in temperature hot spots. For example, greater power draw in rack 1 results in a hot spot near the top of the rear of rack 1. This also results in a slightly higher temperature at the front of rack 1(26.2ºC) from hotter air circulating to the front and not being sufficiently cooled. Focus Group Technologies Pty Ltd. ACN ABN Page 15

16 12 Power Recommendations As mentioned in the observations no particular single device appears to be a major contributor to the power usage, rather the number and density of the devices. Additionally the total power usage is 124% over the total allocated; as such redistribution within the 3 racks would not solve the current problem. As such the recommendations are as follows: (in no particular order) Acquire additional racks adjacent to the current rack/s and move some devices in to the new racks. i.e..spread the load across more rack/s Move the current equipment to rack space that provides more power per rack. With at least % more than measured to account for peaks and growth. With either situation, we recommend that the 3 (or more) racks are evenly distributed for power load so as to even out temperature variations. Focus Group Technologies Pty Ltd. ACN ABN Page 16

18 15 Environmental Monitoring Environmental Monitoring and control is crucial to the smooth running of your data centre. To maximise system reliability you should aim for a stable environment free from wild fluctuations. The key areas of concern are: Temperature Humidity Wetness (optional) Airflow (optional) Observation: Environmental monitoring is currently not implementation Recommendation: Implement an environmental monitoring system that provides alerting and historical reporting. Focus Group Technologies Pty Ltd. ACN ABN Page 18

19 16 Subsequent recommendations: Lastly, if the type of data prepared from this report is beneficial to you in the longer term, we would recommend that Intelligent PDUs or inline power meters be investigated to provide more accurate and detailed information. Intelligent PDUs will allow you to have features such as: Outlet-Level Current/Voltage/Power Metering with Threshold/Alert Capabilities Long term reporting and trending of power usage Capability to Remotely Switch Outlets Through On-Board Web Electronic Overcurrent Protection Sequential Startup Internal Temperature Sensor and Two Optional External Sensors A move or redistribution of racks equipment would be an ideal time to implement such technology.
