A disclosed method for developing and testing a hyper-converged infrastructure (HCI) platform creates a snapshot pool with one or more virtual resource snapshots that include one or more virtual node snapshots, one or more virtual cluster snapshots, or both. The snapshot pool may be maintained with a desired quantity of the virtual resource snapshots by adjusting the composition of the snapshot pool in response to snapshot events, including an event that alters either a composition of the snapshot pool or a configuration of the HCI platform. The desired quantity of virtual resource snapshots may be determined in accordance with one or more snapshot thresholds. The snapshot thresholds may include a snapshot pertaining to a quantity of virtual node snapshots in the snapshot pool and/or a snapshot pertaining to a quantity of virtual cluster snapshots. Specifically, the threshold may include a cluster maximum and minimum and a node maximum and minimum.

A method for haptic feedback, a device for haptic feedback, and a storage device are provided. The method includes the following. In response to a session information editing operation from a first user, session information is generated, where the session information includes Morse code character information. In response to a sending operation from the first user, the session information is sent to a data platform for a second electronic device to obtain the session information from the data platform and to generate haptic feedback according to the session information. In the technical solutions provided in the embodiments of the disclosure, information is sent through the Morse code by utilizing the characteristics of the Morse code, thus simplifying the communication process, improving the interest in the communication process, and improving the user experience.

Disclosed methods define VLAN time slots for one or more VLANs within an HCI environment. A management resource may control virtual application access to each VLAN in accordance with the VLAN time slots wherein only one virtual application may connect to the VLAN during a VLAN time slot. Disclosed methods may define VLAN time slots for each of the plurality of virtual applications. The VLAN time slots may be defined dynamically, wherein durations of the VLAN time slots may be re-calculated each VLAN cycle. A duration of the VLAN time slot for a particular virtual application may be determined based on the number of packets transmitted by the virtual application during a previous VLAN cycle. Each VLAN time slot may include an active interval, for transmitting packets, and an inactive interval. Each active interval may include a fixed duration base interval and a variable duration dynamic interval.

Time division control of virtual local area network (vlan) to accommodate multiple virtual applications

A method for catalytic cracking of naphtha is provided. Naphtha is catalytically cracked under the action of a catalyst. The catalyst includes aluminosilicate, alkali metal oxide, alkaline earth metal oxide, TiO, iron oxide, vanadium oxide and nickel oxide. On the other hand, a rapid separation component is arranged in a disengager of a catalytic cracking reaction device, so that a transport disengaging height is greatly reduced without changing a gas flow and a diameter of the disengager. In addition, the separation efficiency of oil gas and the catalyst is improved.
