The present invention discloses a system for adjusting the speed of operation of a channel for communicating with disk drives in a multi ported system, comprising a bridge controller having a first channel and a second channel and a plurality of enclosure services modules, each having a first channel connected in sequence from a bridge controller to a first enclosure services module and successively connected to successive enclosure services modules to a last enclosure services module and each having a second channel connected in reverse sequence from the bridge controller to the last enclosure services module and successively connected to the successive enclosure services modules to the first enclosure services module. In the disclosed method for changing the speed of operation of a channel, a change speed is performed on either the first or second channel and the other of the first and second channel is used to send change speed frames from the bridge controller to each of the plurality of enclosure services modules.

Method for changing fibre channel speed of a drive loop with ESM-controlled drive boxes using redundant drive channels

A vibration dampening mechanism for operative arrangement with a data storage media drive canister, having: a cantilevered dampening spring secured to a surface of, or integral with, a side of a housing for the drive canister. The spring has a free end that can extend over an aperture through the housing side. The spring can comprise a bent portion, having an outer bend surface, between a secured end and the free encl. When installed in a canister support structure, this outer bend surface will contact an under surface of the structure causing the bent portion to at least partially flatten; the free end may deflect into the aperture. Also, a storage media drive vibration dampening system for operation with a media drive canister support structure having: a cantilevered dampening spring secured to, or integral with, a side of a drive canister housing. And, a method of dampening the vibration of a data storage media drive in operation comprising the steps of: providing a cantilevered dampening spring secured to a surface of, or integral with, a side of a drive canister housing containing the media drive, the side has an aperture through it over which a free end of the spring can extend; and contacting an outer bend surface of a bent portion of the spring with an under surface of a canister support structure to cause the bent portion to at least partially flatten.
