Association Map	Color highlights are used in the floor and rack layouts to indicate components most likely representing the selected device in IT Advisor (IT Advisor: Capacity feature). This overlay is available when you are working with Planning>Device Association and color highlights appear when you select a device in Unassociated Devices if there are one or more potential matches for the device in IT Advisor. Dark Green: Perfect match. The identifying properties of the unassociated device match those of the proposed matching component in the layout. The software expects the match to be unique in the sense that an external item should match with only one piece of equipment in IT Advisor. When highlighting perfect matches, the software compares these properties: ITO asset and Data Center Expert device: IP to IT Advisor component: Port configuration or any custom property ITO asset and Data Center Expert device: Serial number to IT Advisor component: Any custom property Any external system device: Name to IT Advisor component: Label Light Green: Highly likely match. Some properties of the unassociated device match those of the proposed matching component in the layout. The software detects multiple candidates and cannot tell which is the best. However, you can use these highlights to narrow down the components and their location before doing a manual association. When highlighting highly likely matches, the software compares these properties: ITO asset and Data Center Expert device: Model to IT Advisor component: Model ITO asset: Genome to IT Advisor component: Genome Yellow: Likely match. The specified manufacturer of the unassociated ITO device (property) matches that of the proposed matching component in the layout. The software detects multiple candidates and cannot tell which is the best. However, even if there may be many servers of a specific make, you can use these highlights to narrow down the components and their location before doing a manual association. When highlighting likely matches, the software compares these properties: ITO asset: Manufacturer to IT Advisor component: Manufacturer
Cooling	The Cooling overlay gives you a good indication of the effectiveness of the active cooling configuration as well as a qualified estimation of the effect of changes in supply temperature, airflow, and number of cooling units and room-based cooling parameters. Equipment is colored to describe cooling as green: sufficient; yellow: partial; red: insufficient. The tooltip shows you important cooling indicators, such as a cooling unit's capacity (load in kW) and estimated return temperature.
Floor Plenum	This overlay of the data center floor layout shows plenum airflow velocities and perforated tile airflow rates. The tile airflow rate is indicated by tile color and is also shown in the pop-up box when the cursor is placed over a tile.
Floor Plenum Pressure	This overlay of the data center floor layout shows a color-coded overview of the pressure distribution for the type of data center layout that includes a raised floor environment, perforated tiles, and downflow CRACs.
IT Optimize	This overlay shows power utilization of the servers in a rack. Racks are colored to describe the utilization as: green: max amount of servers are utilized; yellow: max amount of servers could be consolidated; red: max amount of servers could be retired. The tooltip includes a graphical overview of the server utilization in a selected rack. (Data Center: IT Optimize feature)
Network	This overlay shows network capacity data for racks with network equipment, including total number of ports and remaining ports. Colors indicate the amount of ports in use: red: all; yellow: almost all. Note The amount of ports shown in this overlay may not be the same as you see in the capacity overview shown in the global map overview. Whereas the floor layout Network overlay shows the amount of ports for racks with network equipment including patch panels, the global capacity overview shows network information represented as a percentage of the available network ports utilized by networking equipment, not including patch panels, in the location or room.
Physical	The physical capacity of racks and their contents is shown, such as available U space. The tooltip shows U and W bars on the racks to indicate the remaining U-space and weight capacity. The weight capacity bar shows how much the equipment placed in the rack layout weighs compared to the carrying capability of the floor or the rack depending on which is the highest. The bar indicators are divided into 3 sections 0-55% green, 56-85% yellow, 86-100% red. Note The floor weight capability is measured in kg/m² or lb/sq.ft. The weight of the equipment is converted into the same unit to identify how much it would weigh per m² or lb/sq.ft, and the percentage of used weight capacity is shown. If alarms occur on associated equipment, alarm icons help you identify precisely where in the layout the alarms occur, for example on a specific UPS in the layout and what the severity of the alarm is.
Power	Power capacity data is provided on top of power consuming components that identifies in detail how much power the component is using. Color is used to identify the power connections between equipment. If the connections span different rooms, the item that is supplied with power from an item in another room will be marked with an icon to indicate the distance (white arrow on a blue background). The tooltip shows E and M bars on the UPS units to indicate the estimated and measured loads. The M bar only occurs when a device from an external system has been associated with the component in IT Advisor.
Provisioning Map	Color highlights are used in the racks to indicate what position is best suited for the selected equipment (IT Advisor: Capacity feature). This overlay is available when you are working with Planning>Asset Provisioning and the color highlights appear when you click Add to Best Rack. Green: Optimum location for the equipment Yellow: Not optimum but possible location (may result in stranded capacity) Red: Location violating your setup (may result in power overload)
Co-lo	The co-lo overlay shows information on space and rack count. See more here.
Cooling Optimize	This overlay shows the thermal influence of an individual cooling unit over the facility, as well as its influence on individual sensors. Go to the Cooling Optimize tab and right click a cooling unit in the layout. Select Show Influence to see the influence map. You can adjust the Influence Scale to get a higher level of detail and a better view of the influence of the cooling units. Go to Tools > Preferences > Cooling Optimize. The rack tool tip shows you the rack temperature on a scale of the high/low limit temperature set points. The CRAC tool tip tells you if the unit is controlled manually or automatically and if the unit is on/off. The small icon 102237512_360038496293.png on the CRAC indicates that the CRAC is controlled automatically. If the icon is blue, it is on, and if it is black, it is off.
