How many servers one column serves

Port count arithmetic · industry practice

A rear aisle with manifold ports feeding hoses into server nodes
Servers per column
100+
Port pitch
Server U height
High port counts
Two-sided

In the industry a single column reaches 100+ servers, with the port pitch following the server U height rather than a fixed spacing. Above a certain count the ports go on both faces of the column.

Discussed: 100+ servers per column · pitch on server U height · two-sided option · rear aisle service

Test gate before it ships

Per-unit leak test · every quick disconnect port

A test bench unit with its chamber closed and hoses running to the fixture
Tested 100% every manifold, including each quick disconnect port
Conditions Static + dynamic both conditions, industry practice
Record Per serial a test certificate per serial number
In market UL / PG25 manifold lines in the market carry a UL declaration and PG25 validation · in-market
Shipping Capped every port plugged for transit

The leak test routine is what the industry does per unit. The UL declaration and the PG25 validation are things that exist on manifold lines in the market; neither is a mark held by DryLink.

Static · pressure held on the assembly

Dynamic · assembly under cycling condition

Height match

How tall is the rack?

Send the rack U count, the port count and whether the feed arrives from the top or the bottom. A 42U rack lands between 1800 and 1900 mm; 48U lands near 2100 mm.
