Abstract: Example embodiments relate to methods, systems, and a computer program product for detecting and responding to the presence of malware persistently executing in a monitored virtual machine of a virtual computing platform. The method includes logging I/O requests at a hypervisor kernel in a kernel log and at a virtual machine (VM) managed by the hypervisor in a VM log. The logged I/O requests then may be compared to detect evidence of malware according to differences between the I/O requests logged in the VM log and the kernel log.

Abstract: A technique for managing synchronous replication and asynchronous replication of both block-based objects and file-based objects employs a common replication session manager configured from a common GUI application. The replication session manager can access different settings for different data objects (e.g., LUNs, file systems, block-based vVOLs (virtual volumes), file-based vVOLs, VMDKs, etc.), with replication settings maintained on a per-data-object basis. The replication session manager can also orchestrate synchronous and/or asynchronous replication sessions, failover, and/or recovery, for any given data object in accordance with the particular data-object-specific settings established for that object.

Abstract translation: 用于管理基于块的对象和基于文件的对象的同步复制和异步复制的技术使用从通用GUI应用程序配置的公共复制会话管理器。 复制会话管理器可以访问不同数据对象（例如，LUN，文件系统，基于块的vVOL（虚拟卷），基于文件的vVOL，VMDK等）的不同设置，复制设置保留在每个数据 - 对象基础。 复制会话管理器还可以根据为该对象建立的特定数据对象特定设置，为任何给定的数据对象编排同步和/或异步复制会话，故障转移和/或恢复。

Abstract: A technique secures data in cloud storage. The technique involves receiving, by processing circuitry, an input/output (I/O) request which includes host data. The technique further involves encrypting, by the processing circuitry, the host data to form encrypted data and sending a block-based write transaction which includes the encrypted data to a replication storage array to store the encrypted data within the replication storage array. The technique further involves storing, by the processing circuitry, the host data within the production storage array. The encrypted host data is stored within the replication storage array to secure the host data which is also stored at the production storage array.
