Can you ask them to raise the ceiling a few inches to get you a minimum of 18” above the cable tray? Other wise tell them you have to add sprinklers below the cable tray and right on top of the servers. That should get them to be willing to move the ceiling up.

The cable tray sits atop the servers at 8-8". I plan on using NFPA 13, 2022 edition, section 10.2.7.3.2.3 and figure 10.2 7.3.2.3. What does it mean in figure, "center of partition less than 12"? Servers are larger than 12", so I cannot use this method? Must resort to 3* rule?
