A sliding rail adapted to be engaged with an engaging member, and includes a track and a limiting mechanism. The track includes a base wall having first and second ends, and two side walls. The limiting mechanism includes an operating member, a limiting member, first and second positioning members, and a connecting member. The limiting member has a limiting body, a pivoting portion, and two limiting portions. The operating member is formed with a linking slot that has a first linking slot end, a second linking slot end, and a linking slot tip. The limiting body has two pivoting slots. The operating member is operable to drive the limiting member to move among a locked position where the engaging member is contained in a limiting space, and first and second unlocked positions which opens the limiting space, allowing the engaging member to be released from the limiting space.

The sliding rail assembly includes an outer rail having a positioning feature, an intermediate rail displaceable relative to the outer rail and having a concave surface facing the positioning feature, a first stopper pivotally connected to the concave surface to correspond to a first side portion of the positioning feature; and an operating device movably connected to the outer rail with a push rod thereof placed in the concave surface and located on one side of the first stopper, so that when the push rod pushes the first stopper along the concave surface, the first stopper is prohibited from blocking the first side portion of the positioning feature.

A server slide can include a first rail and a second rail configured to slidably receive the first rail. In one example, a first pull rod for a locking mechanism can be slidably mounted to the first rail. A second pull rod for the locking mechanism can be slidably mounted to the first rail. The first and second pull rods can be mechanically connected such that actuation of the first pull rod simultaneously actuates the second pull rod to operate the locking mechanism.
