Abstract: Systems, methods, and other embodiments for supporting high availability by using in-memory cache as a database are disclosed. In one embodiment, a system includes an application server that is configured to select a sub-set of data from a remote database that is predicted to be accessed by an application server, wherein the application server includes an in-memory cache. The sub-set of data is reformatted to reduce the size. The in-memory cache is configured to act as a backup database by pre-populating the reformatted sub-set of data into the in-memory cache. In response to detecting the remote database is in an off-line state: the in-memory cache is assigned as a primary database to replace the remote database and subsequent data requests are re-directed from being processed using the remote database to being processed using the in-memory cache.

Abstract: A new peripheral component interconnect express (PCIe) link state can enhance power saving capabilities of a PCIe link operating in a flow control unit (FLIT) mode. A device can operate a data link with a host in a FLIT mode using fixed-sized packets, the data link being in a partial width link state (PLS) in which a first set of lanes of the data link are in an electrical idle state and a second set of lanes of the data link are in an active state available for data traffic with the host. The device can transition one or more lines of the second set of lanes from the PLS to a partial width standby link state (PSLS) in which the one or more lines of the second set of lanes are in a standby state that has lower power consumption than the active state.

Abstract: Aspects relate to link speed for a peripheral component interconnect. In one aspect, an apparatus includes an interface circuit configured to provide an interface with a multiple lane data link, the data link having a first set of lanes in an active state and a second set of lanes in an idle state and a controller. The controller is configured to receive a request at the controller to change a data rate of the data link to a requested data rate, change the second set of lanes from an idle state to an active state, train the second set of lanes to the requested data rate, transfer data traffic from the first set of lanes to the second set of lanes after the training, and transmit the data traffic on the second set of lanes.

Abstract: A storage appliance or system may support backup and recovery for virtual machines that support various applications. The storage appliance or system may process a backup snapshot of the virtual machine to identify security vulnerabilities in the virtual machine. The storage appliance may generate an index of software packages installed on the virtual machine and software versions of the software packages. The index of software packages may be compared to a list of security vulnerabilities to identify the security vulnerability at the virtual machine. A notification may be triggered, and the notification may indicate a result of comparing the index of software packages and the software versions to the list of vulnerabilities. In some examples, a set of network configurations implemented by the virtual machines may be determined by processing the backup snapshot and used to identify security vulnerabilities.
