This section will discuss the hardware model for physical, blade or other device types. A hardware model is a template that specifies the rack display size, depth, image and power calculations for a set of devices.
Hardware Model properties
In the Name field, enter the model name. The manufacturer name will be appended automatically whenever this hardware model is displayed. For example, you can enter PE2950 for a Dell PE2950 and if the manufacturer chosen is Dell, it will add Dell in front when displaying the model.
Type : Indicate whether the model is for a physical device (regular), blade device, or other device (such as laptops, workstations etc.). Depending on what you choose, you will see size or blade size populated in the form.
Size is the size of physical device or type regular in Us. You can enter 1/2 U as well by entering 0.5.
Blade size : the various combinations for possible blade sizes.
Depth : If you want to add back to back devices in the rack, use half depth. Default is Full Depth.
Device type and hardware type relation
By default, when a device is discovered using auto-discovery, it is classified as type “unknown” (unless it is a virtual device).
This is because the discovered device could be a physical device, a blade device or “other” type.
You can change the device type in bulk by changing the type of the associated hardware model.
1. You discovered 50 devices with hardware Dell PE1950 and all devices show as unknown.
2. PE1950 hardware is also created by auto-discovery. You go and change the type to regular (rack mountable) and assign a size of 1U.
3. All associated devices will automatically change to type physical.
4. Any future device discovery with hardware PE1950 is automatically categorized as type physical.
You can do also this efficiently using hardware bulk edit and hardware excel import features.
Hardware Bulk Edit
The video above shows how to make a bulk edit.
As shown in the video, choose Tools > Bulk Operations > Hardware Bulk Edit.
You can quickly change discovered hardware properties and it will automatically add devices to appropriate categories.
Adding images for hardware
You can quickly import images for hardware models and add the images in the hardware edit page, bulk hardware edit page or hardware excel import.
Quickly adding images:
- Go to Tools > Settings > Image files.
- Browse to the image file.
- Save and Add another.
- Repeat 2 & 3.
Image files can be in multiple formats including png, jpg, tif, and others.
Hardware List View
The hardware list view gives you an overview with PSUs and thumbnails for the images. You can filter by manufacturer, size or type from the right hand side bar.
Hardware Merge Function
Using auto-discovery, import or APIs, sometimes you end up with multiple hardware names for same hardware model and devices assigned to each of these. There is a function in hardware edit to merge a hardware model with another hardware model. You have to just make sure size, depth, type and blade size(for blade type) match for these 2 models. It would ask you to choose which hardware to merge into and would re-assign device relationships to chosen hardware object and delete this object.
Hardware Bulk Merge Function
Datacenter > Hardware - select the two more items you wish to merge. From the Action menu, choose “Merge selected hardware models” then click Go.
Next you will be prompted to confirm the hardware model merge.
- Choose the model to become the master, i.e.: the hardware model tha all of the other models will be merged into.
- Optionally you can choose to add the merged hardware model names as alias in the new master. This is strictly for reference. All existing devices will associated with the new master hardware model.
Click “Merge hardware models” to complete the merge.
Note that we still have two hardware models remaining. In the event that the U size is different, the models will not be merged.
