Abstract: 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.

Abstract: Disclosed are ionene polymers having antimicrobial activity. “Ionene polymers” as used in this invention are cationic polymers in which a substantial proportion of the atoms providing the positive charge are quaternized nitrogens located in the main polymeric chain or backbone of the polymer rather than in pendant groups. Also disclosed are antimicrobial compositions comprising ionene polymers and methods for treating microbial infections in mammals comprising the step of administering to a mammal, a therapeutically effective amount of at least one antimicrobial composition of the invention. Also disclosed are antimicrobial compositions comprising at least one ionene polymer and methods for preventing, inhibiting or eliminating the growth, dissemination, and/or the accumulation of microorganisms on a susceptible surface (including, but not limited to, the formation of biofilms on a susceptible surface) comprising the step of contacting such surface with a composition of the invention.
