Abstract: The present disclosure related to a multilayer composite that may include a first polymethylpentene (TPX) liner, and a silicone-based foam layer overlying the first TPX liner. The silicone-based foam layer may include a component A and a component B, where the component A may include a silicone-based matrix component, a first filler component that may include alumina trihydrate, a second filler component that may include perlite, and a third filler component that may include calcium carbonate, and where the component B may include a silicone-based matrix component, a first filler component that may include alumina trihydrate, a second filler component that may include perlite, a third filler component that may include calcium carbonate, and a fourth filler component that may include zinc borate. The silicone-based foam layer may have a V-0 flammability rating as measured according to ASTM D3801.

Abstract: Techniques for monitoring an access request are described. For instance, a method comprises: obtaining a request parameter indicating a target storage space to which the access request is directed; determining a target address range of the target storage space based on the request parameter; determining, in a set of kernel logs, a target kernel log associated with the access request based on the target address range, the set of kernel logs recording operations that occur in a kernel of an operating system; and determining information of an operation of the access request based on the kernel log, the operation corresponding to the target kernel log.

Abstract: Embodiments of the present disclosure provide a method, electronic device and computer program product for handling congestion of data transmission. The method comprises determining whether congestion caused by a plurality of storage nodes occurs at a first port of a switch, the first port being connected to a first storage node, the plurality of storage nodes transmitting data to the first storage node via the first port of the switch. The method further comprises in response to determining that the congestion occurs at the first port, selecting at least a second storage node from the plurality of storage nodes. The method further comprises updating configuration of a data transmission path for the second storage node, such that the second storage node transmits data to the first storage node while bypassing the first port.
