  • Patent number: 11945728
    Abstract: A process for obtaining vanadium component in the form of vanadium oxide from gasifier slag is disclosed. The process comprises pulverizing the slag to obtain pulverized slag, which is blended with water and an alkali salt to obtain a slurry. The slurry is dried and then roasted in the presence of air to obtain a roasted slag. The roasted slag is leached to obtain a first filtrate comprising the vanadium component. The first filtrate is reacted with a magnesium salt to remove a silica component in the form of a precipitate. The silica free second filtrate is reacted with an ammonium salt to obtain ammonium metavanadate, which is further calcined to obtain the significant amount of vanadium pentoxide (V2O5).

  • Patent number: 11909612
    Abstract: Some embodiments provide a novel method of performing health monitoring for resources associated with a global server load balancing (GSLB) system. This system is implemented by several domain name system (DNS) servers that perform DNS services for resources located at several geographically separate sites. The method identifies several different groupings of the resources. It then assigns the health monitoring of the different resource groups to different DNS servers. The method then configures each particular DNS server (1) to send health monitoring messages to the particular group of resources assigned to the particular DNS server, (2) to generate data by analyzing responses to the sent health monitoring messages, and (3) to distribute the generated data to the other DNS servers. The method in some embodiments is performed by a set of one or more controllers.

  • Patent number: 11909719
    Abstract: Techniques and technologies for an Internet Protocol (IP) address management (IPAM) system to track and manage IP address workflows in a network. The IPAM system can be used to define and enforce management policies or rules regarding IP address management, such as allocation policies, refill policies, and so forth. For instance, the IPAM system can enforce allocation policies that define rules to allow or deny allocation of IP addresses based on types of resources for which the IP addresses are requested, registered user accounts that are requesting the IP addresses, the purpose of the resources receiving the IP addresses, and so forth. Additionally, the IPAM system can enforce refill policies that define rules for replenishing inventories of IP addresses that have been allocated for different domains in the network. The IPAM system can improve the management of IP address workflows by enforcing policy and tracking IP address workflows in networks.

  • Patent number: 11907114
    Abstract: In certain aspects, dynamic remapping of memory addresses is provided and includes initiating a remapping of a logical block from a “mapped block” to a “remapped block.” Logical address locations for the logical block are mapped to physical address locations in the mapped block. The mapped and remapped blocks include non-volatile memory. A read command is received and determined to be for reading from a logical address location of the logical block, and the logical address location is determined to be mapped to a physical address location. Data is read from the physical address location of the mapped block. A write command is received and determined to be for writing data to the logical address location. Data is written to the physical address location of the remapped block. The read command is received after the initiation of the remapping and before the writing of the data to the remapped block.
