Frequently Asked Questions

AUDIT-BUDDY Questions

AUDIT-BUDDY is a portable and standalone temperature and humidity monitor. It consists of three temperature and humidity sensors and 1 carbon fiber rod with weighted base. It is portable, battery powered and has a low learning curve— no new programs/installations--- just scan and use Excel to view data. The key advantage is that AUDIT-BUDDY can spot check air quality and diagnose cooling issues in areas without permanent monitoring.

AUDIT-BUDDY™ is a tool aimed at transient monitoring applications with no demands on the existing infrastructure. Users can deploy AUDIT-BUDDY™ where they suspect a problem, or if they need to baseline their facility, then put AUDIT-BUDDY™ away, without leaving any footprint in the datahall.

Wireless sensors require monitoring infrastructure to be set-up to collect information and users must keep track of where the sensors are located, adding to the RF pollution in the white space.

Infrared guns are not, and cannot, be as accurate as AUDIT-BUDDY™. Infrared guns can only measure the temperature of the surface of the server and can’t measure true air temperature. In addition, the color of the reflecting surface affects the temperature measurement.  If you are assessing data center operating efficiency by minute changes in the CRAC settings, where 1°F change is significant, you really can’t measure that impact with an IR gun. AUDIT-BUDDY™ on the other hand is an accurate tool to measure such minor change impacts.

AUDIT-BUDDY, like many data loggers such a measure both temperature and relative humidity. However, AUDIT-BUDDY differs in its standalone design and ability to both record and diagnose data.

The construction of Audit-Buddy allows you to measure the inlet or outlet air going into the server at three different heights simultaneously. This provides an accurate account of the whole rack environment, rather than an individual point. Measurement of the air temperature going in or out simultaneously of the server is key, as it lets you determine your cooling efficiency. Stated another way, the Audit-Buddy system provides you temperature stratification information for your cold and hot aisles without requiring any special installation, without touching the server or hanging multiple sensors from the ceiling.

The second key difference is with the information supplied. The Audit-Buddy system tells you what's causing your thermal issues (hot spots, overcooled regions etc.), how effective your cool efficiency is, and how much cold air you're wasting due to bypass and recirculation airflow. Our software is designed to make it easy to quickly post-process data, without wasting a lot of time. Audit-Buddy is a data center application focused tool that provides information about the cooling system, not just the raw data. 

AUDIT-BUDDY recordstemperature and humidity per location and the software allows the users to easily manipulate the data into meaningful information.

For example, users interested in cutting down on cooling can use AUDIT-BUDDY to measure every cabinet across the facility using the QuickScan mode and visually translate represent air profile of the aisle and pinpoint where their are hotspots or over cooled areas using Optimize Macro “Create Contour Map” function. The Interactive Data Hall program lets the user look at the entire data hall data in a comprehensive manner. After deciding to focus on specific problem areas, the user can then use the Delta-T scan to collect long term trend data and identify what causes the hot spot. 

A basic list of data functions is provided below:

  • Quickly Collect data for every cabinet environment
  • Collect Long term trend data for a single stand
  • View Scan highlights
  • View time-trend graphs with customized alarm limits
  • Create “CFD-like" Contour Map with real-time data. 
  • Diagnose server specific cooling efficiency
  • Calculate cost of “overcooling” in terms of OpEX and Consumption
  • Create Interactive “aerial” Data Hall Views to quickly drill down and isolate problem areas

Most hotspot or overcooled areas stem from poor  airflow management in data centers. Purkay Labs recommends using two AUDIT-BUDDY systems, one placed in front of the cabinet and one place in the back of the cabinet, to measure the server delta-T. This measurement when read through the Optimize Excel Macro, AUDIT-MATE or WIFI-MATE indicates how effectively the servers are being cooled.The Purkay Labs software shows how much cold supply air is reaching the server and how much is lost due to bypass and/or recirculation airflow. 

Users should measure server delta-T to prevent downtime and benchmark cooling efficiency. Today most data centers monitor temperature in order to ensure that the inlet air going into the server meets equipment or industry standards, or be alerted to potential problems to prevent server failure or downtime. At the same time, inlet air temperatures can fall within an acceptable range and still be at risk.

Data Centers are designed to maximize cooling by supplying cold “supply” air directly to the IT equipment and returning the warm “return” air directly to the cooling unit (CRAC/HVAC). Ideally, all of the cold supply air will reach the server inlet and all of the warm return air will reach the CRAC return with no or minimal waste. In reality, a significant amount of cold supply air is wasted because it either bypasses the IT equipment completely or it mixes with warm return air that is sucked back to the server inlet rather than the cooling unit. A long-term Uptime Institute study found that only 60% of cold air pumped into 19 data centers actually reached IT equipment. Poor airflow results in hot spots, higher energy con

sumption and higher utility cost. As managers increase load capacity, add blade servers or make any changes to the data center layout that inevitably effect the thermal environment, it is imperative to measure both inlet and outlet temperatures.

AUDIT-BUDDY is a simple tool that lets you measure this valuable parameter without requiring the expense of a large monitoring system. 

AUDIT-BUDDY is used in over 60 sites across the US, Canada and UK. Our end-users range from industries including: e-commerce, telecommunications, financial institutions, colocation providers, and commissioning/server agents. The majority of our clients are Tier 2-4 facilities. 

AUDIT-BUDDY is designed to be operational right out of the box. By design, there is no installation or integration required affecting the existing infrastructure. 

You can place AUDIT-BUDDY as close as an inch away from the server rack using the carbon fiber rod or fix it directly to the surface using the magnetic plate.

Purkay Labs recommends placing one TH1 Module near the floor, one TH1 Module close to the top of the rack and one TH1 Module in the middle of the cabinet to get a detailed stratification of the cabinet.

AUDIT-BUDDY uses standard alkaline AA batteries for operation. The low power design allows the user to operate the unit without requiring frequent replacements. Under normal operating conditions, used once or twice a week, the batteries will last for at least 6 months.  A low battery warning is displayed before the user starts a data collection. The user can also test the module’s current battery condition at any time. The scanned data is stored in Non-Volatile Memory and is not dependent on battery voltage, and therefore is not lost when the batteries are removed to be replaced.

AUDIT-BUDDY design allows you to transfer data one of three ways. The simplest is using a USB Flash Drive to transfer the data after the sampling is complete. For facilities where USB Flash Drives aren’t allowed, one can use the supplied USB cable to directly download the data from the module to the PC/tablet using the AUDIT-MATE PC program. The third approach uses the 802.11 WIFI. One needs to add a WIFI Adapter Module to make the TH1 module communicate via WIFI. The sampled data is automatically streamed directly to your PC or Tablet.

Yes.Using the new WIFI adapters that plug into the existing TH1 Module, users can stream data via their WIFI network* or router to WIFI-MATE. Purkay Labs is currently beta testing this function and is expected to release “AUDIT-BUDDY” in mid to late 2016.                                                                                                                    *Subject to facility security protocols.

Purkay Labs offers an annual verification service, for an additional fee, at the factory with a NIST traceable instrument. Please contact the Customer Service team at info@purkaylabs.com for more information. 

All software and macros supplied by Purkay Labs are digitally signed and time stamped for security systems designed to reject files that are not. To communicate to the TH1 module from the PC and Tablet, two different industry USB standard drivers are required.  These are supplied by Purkay Labs along with the AUDIT-BUDDY system. Contact your site IT Security person if you have any questions regarding driver installation.

WIFI-BUDDY uses industry standard 802.11 b/g 2.4GHz WIFI. The PC and WIFI Adapters use dynamic IP assignment by the router. The Authentication System supports WEP-128, WPA-PSK(TKIP) and WPA2-PSK(AES). Contact your site Wireless Security personnel to insure that the site WIFI will allow devices to initiate and receive UDP packets. Purkay Labs also supplies an off the shelf router, should you wish to use a temporary network for WIFI communications. 

All collected data from Purkay Labs Software and Macros support data export in .CSV and .PNG formats. Specific integration to a building automation system will require a custom wrapper to be written. This will vary from site to site based on the specific requirements. Please contact Purkay Labs for more information. 

By design AUDIT-BUDDY is designed to be non-intrusive, does not touch the existing server hardware and is meant to be for temporary use. After the data is collected, the system is meant to go back to the storage closet, leaving the data hall free and clear. There is no risk to the data center operation if the AUDIT-BUDDY system is operated as designed.

WIFI-BUDDY Questions

WIFI-BUDDY is the wireless version of AUDIT-BUDDY that allows users to stream real-time data via a personal or facility WIFI network. Each WIFI-BUDDY system consists of 3 WIFI-Modules (3 TH1 Modules and 3 WIFI adapters) and a carbon fiber rod. WIFI-BUDDY uses the WIFI-MATE program to configure and analyze data from up to 10 WIFI-BUDDY stands (30 WIFI Modules.)
The WIFI Adapter is a plug-in adapter that transmits data collected in the TH1 Module to a remote PC or tablet.
WIFI-MATE is the PC based program used to configure WIFI-Modules and analyze data. Users can connect up to 10 stands or 30 WIFI-Modules.
In terms of hardware, WIFI-BUDDY can stream real-time data directly to a PC whereas users must download AUDIT-BUDDY data via a USB stick or cable. During the scan process, WIFI-BUDDY users can start and stop all modules simultaneously with one click. The WIFI-BUDDY software, WIFI-MATE, has enhanced analytical capabilities that allow users to see real-time time-trend graphs, contour maps and enhanced automated cooling performance graphics.  
Each WIFI adapter use four standard (AA) alkaline batteries. Battery life varies between 12-24 hours based on scan type. There is a low battery warning when adapter or TH1 Module batteries fall below safe operating thresholds. Should battery failure occur, data collected up to that point is stored in the WIFI-MATE PC . Purkay Labs recommends using the supplied 100-240AV WIFI power brick for long term scans.
WIFI-BUDDY uses 4 AA Batteries (Alkaline or Lithium) for short term monitoring or a 100-240VAC Power Brick supplied with the adapter.
WIFI-BUDDY has been rigorously tested in a number of facilities. Purkay Labs’ offers a “Tester” program to confirm that the WIFI-BUDDY system works with your facilities’ IT Protocols. To ensure there are no IT restrictions, we ask that you verify that:•Your facility allows peer to peer communication as WIFI BUDDY uses P2P via UDP protocol•You have permission to install Silicon Labs’ drivers•You can authorize program communication through Windows Firewall 
Yes, WIFI-BUDDY is designed to work with facility WiFi. WIFI-BUDDY uses 802.11 b/g/n for communication. Users should check facility signal strength before conducting a scan to ensure that the facility WIFI signal reaches the top and bottom of all cabinets in the hall. Purkay Labs recommends using the cell phone signal strength as a good indicator for WIFI-connectivity. If signal strength is poor, users can use a separate router WiFi network.
No. The first generation of WIFI-MATE currently requires the PC and WIFI-BUDDY to be on the same network. Purkay Labs is currently working on a second generation remote monitoring capabilities.
WIFI-MATE is a .EXE application program that is digitally signed and time-stamped with a traceable code. Please check with your IT department if you need permission to install and run a Digitally Signed .Exe file.

Interactive Data Hall Questions

The Interactive Data Hall is a software program designed to store and visualize multiple QuickScan files. Users can build their own data hall – by themselves or with Purkay Labs’ assistance- with racks, aisles, perforated tiles, PDUs, CRAC units. Then users can upload various sets of data that has been collected.

Users can:

  • View a bird’s eye view layout of the data hall
  • Identify Hot and Cold Aisles
  • Sort through Maximum, Minimum or Average temperatures
  • Change Top, Middle, Bottom or Average view
  • Filter data for temperatures above, below, or between user defined or ASHRAE ranges
  • Display Perforated Tile Openings (25%, 50%, 75% and 100%)- Add custom notes to individual tiles
Purkay Labs recommends using two operators and estimating about 1 minute per cabinet for data collection. Users should note the following:-TH1 Module Heights on the rod-Tile Size-Grid Layout (Tile Name Convention, Top Left Hall Coordinate, Bottom Right Hall Coordinate, Start and Stop/Pause tile for each aisle,-Scan Direction (Note first scan location for each aisle, Pause or Stop)
The Interactive Data Hall is based on the tile layout of your facility. In some instances, cabinets will overlap two tiles. Please place the AUDIT-BUDDY in the middle of the tile, rather than the middle of the cabinet to ensure consistency. Purkay Labs uses the Grid convention to orient users while creating data hall layout and uploading files. Users should choose one orientation and one type of scan path to ensure consistency and accuracy.
Yes, the Interactive Data Hall program can use both AUDIT-BUDDY (.QPL files) or WIFI-BUDDY data.
