Abstract: One or more techniques and/or systems are provided for detecting stale data and/or changed data. For example, a bitmap file may be maintained and mapped to an inofile describing various states of files of a file system. The bitmap file may be populated with bitmap records indicating whether files were accessed, modified, or have other states. The bitmap file may efficiently convey information used to determine whether files have not been accessed recently (e.g., stale data) or were recently modified (e.g., changed data) compared to the inofile because the bitmap file may comprise a fraction of the size of the inofile (e.g., a byte of information may be used to represent various states of one or more files). In this way, instead of evaluating a relatively larger inofile, the bitmap file may be evaluated to efficiently identify stale data for deletion or destaging and/or changed data for backup.

Abstract: A method, non-transitory computer readable medium, and device that assists with dynamically determining and readjusting failover targets includes identifying an existing failover target from a plurality of failover targets for backing up an updated object. The identified existing failover target is determined for eligibility for backing up the updated object. One or more new failover targets from the plurality of failover targets are dynamically identified based on a plurality of storage parameters when the identified existing failover target is determined not to be eligible for backing up the updated object. The updated object is backed up in one of the dynamically identified one or more new failover targets.

Abstract: A method, non-transitory computer readable medium, and computing device that loads a scripting framework module into a runspace. The module includes a command including a noun, a verb, a parameter set, and a return type of the parameter set. Source code comprising a noun class corresponding to the noun, a build command method in the noun class corresponding to the verb, and a parameter set method in the noun class corresponding to the parameter set is generated. The build command method generates and returns an object and the parameter set method constructs and invokes the command using the build command method and converts a collection of objects returned in response to the command invocation into an enumerable of the return type. The source code, or a proxy dynamic link library (DLL) generated by compiling the source code, is output to an output directory.

Abstract: One or more techniques and/or systems are provided for dynamically provisioning logical storage pools of storage devices for applications. For example, a logical storage pool, of one or more storage devices, may be constructed based upon a service level agreement for an application (e.g., an acceptable latency, an expected throughput, etc.). Real-time performance statistics of the logical storage pool may be collected and evaluated against the service level agreement to determine whether a storage device does not satisfy the service level agreement. For example, a latency of a storage device within the logical storage pool may increase overtime as log files and/or other data of the application increase. Accordingly, a new logical storage pool may be automatically and dynamically defined and provisioned for the application to replace the logical storage pool. The new logical storage pool may comprise storage devices expected to satisfy the storage level agreement.

Abstract: The present invention provides a system and method for a shared write address protocol (SWAP) that is implemented over a remote direct memory address (RDMA) connection. Each party to a connection establishes a flow control block that is accessible to its partner via a RDMA READ operation. The novel protocol operates so that each module needs to have one outstanding RDMA READ operation at a time, i.e., to obtain the current flow control information from its partner. In operation, if data to be transmitted is less than or equal to a buffer size, an INLINE message data structure of the SWAP protocol is utilized to send the data to be target. However, if the data is greater than the buffer size, a second determination is made as to whether sufficient space exists in the message pool for the data. If insufficient space exists, the sender will wait until sufficient space exists before utilizing a novel WRITE operation of the SWAP protocol to transmit the data.

Abstract translation: 本发明提供了一种通过远程直接存储器地址（RDMA）连接实现的共享写地址协议（SWAP）的系统和方法。 连接的每一方都建立一个可通过RDMA READ操作访问其对方的流控制块。 新颖的协议操作使得每个模块一次需要具有一个未完成的RDMA READ操作，即从其伙伴获得当前的流控制信息。 在操作中，如果要发送的数据小于或等于缓冲区大小，则使用SWAP协议的INLINE消息数据结构将数据发送到目标。 然而，如果数据大于缓冲区大小，则进行关于数据的消息池中是否存在足够空间的第二确定。 如果空间不足，则在使用SWAP协议的新颖WRITE操作传输数据之前，发送方将等到有足够的空间存在。

Abstract: Systems and methods disclosed herein provide intelligent filtering of system log messages having low utility value. In providing the filtering, the systems and methods determine the utility value of a system log message and delete the message from the system log if the message is determined to be of low utility value. As such, embodiments herein provide an system log filter, which reduces the amount of data stored in the system log based on the utility value of the message.

Abstract: A system, method, and computer program product is described for providing dynamic enabling and/or disabling of protection information (PI) in array systems during operation. A storage system receives a request to transition a volume from PI disabled to PI enabled during regular operation. The storage system synchronizes and purges the cache associated with the target volume. The storage system initiates an immediate availability format (IAF-PI) process to initialize PI for the associated data blocks of the volume's storage devices. The storage system continues receiving I/O requests as the IAF-PI process sweeps through the storage devices. The storage system inserts and checks PI for the write data as it is written to the storage devices. The storage system inserts PI for requested data above the IAF-PI boundary and checks PI for requested data below the IAF-PI boundary. The transition remains an online process that avoids downtime.

Abstract: A method and system for dynamic rule-based automatic crash dump analysis are described. In an example, a dynamic rule-based crash dump analysis system retrieves debug symbol data, rules, and commands from a server over a network. The actions are executed based on the retrieved rules in order to automatically analyze a crash dump using a debugger and the debug symbol data. During the process of analyzing the crash dump, the system parses output from the debugger for further rule processing and creates a human-readable analysis file from the parsed output.
