First, let’s recall that the standard width of a server rack is 19 inches, while the UCS Blade Chassis has a width of 17.5 inches. To calculate the number of chassis that can fit, we need to divide the available width of the rack by the width of each chassis.
Here’s an example to illustrate the calculation:
Step 1: Determine the available width of the server rack.
Assuming we have a standard 42U server rack with an inner width of 19 inches, the available width is 19 inches.
Step 2: Determine the width of the UCS Blade Chassis.
Considering that the UCS Blade Chassis has a width of 17.5 inches for each chassis, we have the width per chassis as 17.5 inches.
Step 3: Calculate the number of chassis that can fit.
Divide the available width of the server rack (19 inches) by the width of each UCS Blade Chassis (17.5 inches).
Number of Chassis = (Available Width / Width per Chassis)
Number of Chassis = (19 inches / 17.5 inches)
Number of Chassis ≈ 1.09
In this example, it can be determined that approximately 1 UCS Blade Chassis can fit in the server rack.
