Abstract: A large-particle spherical salt with a particle size of 400-950 ?m and a sphericity of 0.5-1.0 is disclosed, which overcomes the existing difficulty in this field for larger particle size as well as higher sphericity. A preparation method of the large-particle spherical salt is also disclosed, wherein in one preparation process, 2% of gum arabic (based on the mass percentage of solute sodium chloride in a sodium chloride saturated solution) is added, and under conditions of an evaporating temperature of 60° C. a stirring rate of 350 rpm, and an evaporating time of 8 hours, a large-particle spherical salt with a particle size of 921.593 ?m and an average sphericity of 0.904 is successfully prepared. The large-particle spherical salt prepared by the method has a uniform particle size distribution and good appearance, can be combined with other substances, adding some extra value to the salt. Meanwhile, the large-particle spherical salt prepared by the method has a high safety grade (e.g.

Abstract: A distributed virtual switch system comprises a controller and multiple servers. Each server is configured with a virtual SDN switch and at least one VM. Each VM is connected with an external physical switch via the SDN switch. The controller obtains interface information of a switch logic interface corresponding to a VM, adds an entry comprising the interface information into a local global interface management table. The interface information includes a global unique identifier of the switch logic interface corresponding to the VM, a switch identifier of an SDN switch corresponding to the switch logic interface, and a local port identifier of the SDN switch corresponding to the switch logic interface. The controller manages each VM connected with each SDN switch according to the local global interface management table.

Abstract: Transparent communication between iSCSI and FCoE end nodes is provided by a gateway device having iSCSI and FCoE network interfaces. The gateway allows end nodes of one protocol to communicate with end nodes of another protocol as if they were communicating with end nodes of the same protocol. The gateway accomplishes this by creating “ghost” end nodes for each protocol. For example, the gateway creates ghost iSCSI nodes corresponding to physical FCoE nodes, and ghost FCoE nodes corresponding to physical iSCSI nodes. A ghost end node of a particular protocol is able to communicate with native end nodes of that protocol as if it were a native end node, because the gateway translates packets sent from end nodes in their native protocol into the other protocol for receipt by corresponding ghost nodes, and vice versa.
