A datacenter may include a server rack supported on a floor that is supported over a subfloor. The server rack may be anchored through the floor to the subfloor by a linkage that extends through the floor. The linkage may include a rack anchor secured to the server rack and a subfloor anchor secured to the subfloor. A cable and turnbuckle or other linkage components may be arranged between the rack anchor and subfloor anchor and may be used collectively for removing slack from the linkage and/or otherwise tensioning the linkage to anchor the server through the raised floor and via the linkage to the subfloor.
