Kaiwang, I track basic HDD info by adding two new attributes and associating them to the "server" object. The two attributes are "Num. HDD bays", an unsigned integer, and "Num. HDDs", a string. Below is how we fill in the information. These figures are searchable, and a quick way for us to be able to see how many disks, their speed and size, are installed. If you had the same configurations on multiple servers, you could just create these as dictionary items and make them dropdowns. Hope this helps. Examples: Num. HDD bays: 6 Num. HDDs: 6 x 300GB 10k Num. HDD bays: 8 Num. HDDs: 2 x 146GB 15k Additionally, I track RAID configuration with the below custom attributes. RAID -Driver Version - string RAID -Firmware Version - string RAID -Model - drop down RAID Driver Version (2nd Card) - string RAID Firmware Version (2nd Card) - string RAID Model (2nd Card) - drop down Attached is a screenshot showing the summary of details that includes the HDD and RAID info. Thanks, Matthew Castanien
