Technologies for storage cluster quality of service (QoS) management include multiple compute devices in communication via a storage network. A controller node monitors network traffic of the storage cluster. The network traffic includes a replication traffic class and a rebuild traffic class. The controller node determines whether burst bandwidth is required by the storage cluster and, if so, applies a group policy indicative of burst bandwidth to the storage cluster. The group policy may be applied to an end to end path of the storage cluster. Applying the group policy may include setting one or more bits or fields of an overlay network header of network traffic of the storage cluster. Other embodiments are described and claimed.

The device also includes a first fixing plate, where the first fixing plate is fixedly connected with a second fixing plate through a damping spring, the side walls of a first supporting door frame and a second supporting door frame are embedded with dustproof filter screens, a clamping outer frame is bonded with a first soft cushion block, a sliding supporting block is rotatably connected with a fastening screw, a fixed supporting block and the sliding supporting block are both fixedly connected with a fastening pressure plate through a fastening spring, the fastening pressure plate is bonded with a second soft cushion block, and the supporting frame is embedded with a heat-dissipating fan and a heat-dissipating filter screen, respectively.

A method and apparatus for removing a daughter board from a mother board.

Proposed is a memory module socket capable of increasing electrical contact reliability. The memory module socket includes a socket body (100) including a slot (111) in which terminals (13) of a memory module are inserted, a plurality of receiving portions (113) symmetrically defined by a plurality of partition walls (112), and a stopper member (114) provided under the slot (111), at least one pair of contacts (200) symmetrically provided in each pair of receiving portions (113); and an elastic body (300) inserted into the socket body (100). Each of the contacts (200) includes a curved portion (210), an outer extension portion (220), a first protrusion (222), an inner extension portion (230), an inclined extension portion (240) including a first contact protrusion (240a), and a vertical extension portion (250). Each of the receiving portions (113) includes restraining surfaces (118a and 118b).

A portable information handling system modular hybrid architecture separates components between rotationally coupled housing portions to minimize cabling, connectors and materials, and to provide improved durability that supports recycling and reuse of the components. For example, a plurality of display configurations couple to housing portions of different dimensions with opposing couplers and a common keystone element that, when installed, prevents separation of the opposing couplers. Removal of the keystone element provides ready access to the housing portion interior to recycle processing components, such as a main board having a processor and memory.
