A storage chassis may be adapted, or configured, to secure a plurality of carrierless devices (e.g., without the use of a carrier or drive tray) received thereby. The storage chassis may include a base, a first drive wall coupled to and extending from the base, and a second drive wall coupled to and extending from the base. The first drive wall may be spaced apart from the second drive wall. The base, the first drive wall, and the second drive wall may define a row of drive slots and each drive slot of the row of drive slots may be configured to receive a carrierless device. Further, the storage chassis may include a plate extending across the row of drive slots and may be configured to extend over the carrierless devices received by the row of drive slots.

Technologies for allocating resources of a set of managed nodes to workloads based on resource utilization phase residencies include an orchestrator server to receive resource allocation objective data and determine an assignment of a set of workloads among the managed nodes. The orchestrator server is further to receive telemetry data from the managed nodes, determine, as a function of the telemetry data, phase residency data, determine, as a function of at least the phase residency data and the resource allocation objective data, an adjustment to the assignment of the workloads to increase an achievement of at least one of the resource allocation objectives without decreasing the achievement of any of the other resource allocation objectives, and apply the adjustment to the assignments of the workloads among the managed nodes as the workloads are performed.

Examples may include sleds for a rack in a data center including physical compute resources and memory for the physical compute resources. The memory can be disaggregated, or organized into first level and second level memory. A first sled can comprise the physical compute resources and a first set of physical memory resources while a second sled can comprise a second set of physical memory resources. The first set of physical memory resources can be coupled to the physical compute resources via a local interface while the second set of physical memory resources can be coupled to the physical compute resources via a fabric.

An electronic device includes pairs of guide rails and elastic members. The pairs of guide rails are provided in a slot correspondingly to both ends of the circuit board in a direction intersecting the insertion direction, the guide rails of each pair extending along the insertion direction respectively on sides of both surfaces of the circuit board inserted in the slot, the pair of guide rails being configured to guide insertion of the circuit board into the slot. When the circuit board is inserted in the slot, each elastic member presses the circuit board against one or the other of the guide rails of the pair.

A substrate guide member is integrally formed of resin, and includes: a support portion fixed in a casing; and at least one pair of a first protrusion and a second protrusion protruding from the support portion and extending in an insertion direction with a gap from each other, to thereby form a groove for allowing passage of a substrate. The at least one pair of the first protrusion and the second protrusion includes: a plurality of guide portions configured to guide the substrate; and separated portions, which are portions connecting the plurality of guide portions and have a gap larger than the gap of the plurality of guide portions.

Technologies for dynamically allocating resources within a self-managed node include a self-managed node to receive quality of service objective data indicative of a performance objective of one or more workloads assigned to the self-managed node. Each workload includes one or more tasks. The self-managed node is also to execute the one or more tasks to perform the one or more workloads, obtain telemetry data as the workloads are performed, determine, as a function of the telemetry data, an adjustment to the allocation of resources among the workloads to satisfy the performance objective, and apply the determined adjustment as the workloads are performed by the self-managed node. Other embodiments are also described and claimed.

Embodiments are generally directed apparatuses, methods, techniques and so forth to receive a sled manifest comprising identifiers for physical resources of a sled, receive results of an authentication and validation operations performed to authenticate and validate the physical resources of the sled, determine whether the results of the authentication and validation operations indicate the physical resources are authenticate or not authenticate. Further and in response to the determination that the results indicate the physical resources are authenticated, permit the physical resources to process a workload, and in response to the determination that the results indicate the physical resources are not authenticated, prevent the physical resources from processing the workload.

A 1 U connection chassis and a 1 U cabinet, wherein two or more intermediate plates (16) mutually parallel to one another are disposed inside the 1 U connection chassis; each of the intermediate plates (16) is provided with one or more slots mutually parallel to one another; two opposing slots on two adjacent intermediate plates (16) respectively constitute a mounting dock; an adaptor module (18) or a splice tray (19) is slidably inserted into each mounting dock; optical fiber adaptors are mounted inside the adaptor module (18). The chassis has optimized internal mounting space to allow more adaptor modules and/or splice trays to be mounted in the limited mounting space.

Technologies for a low-latency interface with data storage of a storage sled in a data center are disclosed. In the illustrative embodiment, a storage sled stores metadata including the location of data in a storage device in low-latency non-volatile memory. When accessing data, the storage sled may access the metadata on the low-latency non-volatile memory and then, based on the location determined by the access to the metadata, access the location of the data in the storage device. Such an approach results in only one access to the data storage in order to read the data instead of two.

A component mounting part has a width shorter than a distance between guiderails. Backside projected parts protrude in a width direction from the component mounting part at a case-backside end. A width K2 which is a sum of a width of the component mounting part and widths of the backside projected parts is greater than a distance G1 between the guiderails. A clearance is formed between the circuit board and the heat conduction member when the backside projected parts are supported by the guiderails. A distance G3 from an insertion slot to an end of the guiderail on the case backside, is shorter than a distance K4 from an end of the circuit board on the side of the insertion slot to an end of the backside projected part on the side of the insertion slot.
