Abstract: A method for migration of operations between CPU cores, the method includes: processing, by a source core, one or more tasks and one or more interrupt service routines; accessing a mapping corresponding to a task of the one or more tasks and an interrupt service routine of the one or more interrupt service routines; identifying, based on the mapping, a target core that corresponds to the task and the interrupt service routine; blocking the task from being processed by the source core in response to identifying the target core; in response to identifying the target core, disabling an interrupt corresponding to the interrupt service routine; in response to identifying the target core, assigning the task and the interrupt to the target core; after assigning the interrupt to the target core, enabling the interrupt; and after assigning the task to the target core, processing the task by the target core.

Abstract: Systems and techniques for performing a data transaction are disclosed that provide data redundancy using two or more cache devices. In some embodiments, a data transaction is received by a storage controller of a storage system from a host system. The storage controller caches data and/or metadata associated with the data transaction to at least two cache devices that are discrete from the storage controller. After caching, the storage controller provides a transaction completion response to the host system from which the transaction was received. In some examples, each of the at least two cache devices includes a storage class memory. In some examples, the storage controller caches metadata to the at least two cache devices and to a controller cache of the storage controller, while data is cached to the at least two cache devices without being cached in the controller cache.

Abstract: Described herein is a system and method for a scalable crash-consistent snapshot operation. Write requests may be received from an application and a snapshot creation request may further be received. Write requests received before the snapshot creation request may be associated with pre-snapshot tags and write requests received after the snapshot creation request may be associated with post-snapshot tags. Furthermore, in response to the snapshot creation request, logical interfaces may begin to be switched from a pre-snapshot configuration to a post-snapshot configuration. The snapshot may then be created based on the pre-snapshot write requests and the post-snapshot write requests may be suspended until the logical interfaces have switched configuration.

Abstract: Described herein are systems and methods for storage and deployment of VMs in a virtual server environment. A VM deployment module executing on a server may produce VM container objects representing VMs, a VM container object comprising VM data describing a VM and vdisk configuration data. The VM deployment module may also later produce VMs on a server using the VM container objects. The VM deployment module may do so by producing a vdisk from a VM container object, the vdisk comprising the VM and vdisk configuration data. Rather than configuring the vdisk as typically done to make the vdisk useable to the server, the vdisk configuration data is used to make the vdisk useable and the VM data on the vdisk immediately accessible to the server. As such, the VM data may be immediately read to produce a VM on the server, thus providing rapid deployment of VMs.

An apparatus includes a processor component of an enrollment server; a selection component of the enrollment server to analyze an aspect of the storage of client data by at least one storage device of a storage system to determine a topic of interest to the operation of the storage system, and to enroll an administration device of the storage system as a recipient of a news feed based on the topic of interest; and a triggering component of the enrollment server to trigger a distribution server to transmit a document associated with the news feed to the administration device in response to the enrollment of the administration device.

Abstract: A technique preserves efficiency for replication of data between a source node of a source cluster (“source”) and a destination node of a destination cluster (“destination”) of a clustered network. Replication in the clustered network may be effected by leveraging global in-line deduplication at the source to identify and avoid copying duplicate data from the source to the destination. To ensure that the copy of the data on the destination is synchronized with the data received at the source, the source creates a snapshot of the data for use as a baseline copy at the destination. Thereafter, new data received at the source that differs from the baseline snapshot are transmitted and copied to the destination. In addition, the source and destination nodes negotiate to establish a mapping of name-to-data when transferring data (i.e., an extent) between the clusters. Illustratively, the name is an extent key for the extent, such that the negotiated mapping established by the source and destination is based on the extent key associated with the extent.

Abstract translation: 一种技术保留了源集群（“源”）的源节点与群集网络的目标集群（“目标”）的目标节点之间的数据复制的效率。 集群网络中的复制可以通过利用源上的全局在线重复数据消除来识别和避免将来自源的重复数据复制到目的地来实现。 为确保目标上的数据副本与源中接收到的数据同步，源将创建数据的快照，以用作目标的基准副本。 此后，源头接收到的与基线快照不同的新数据将被传送并复制到目的地。 另外，源和目的地节点协商在传送数据之间建立名称到数据的映射（即扩展）。 示例性地，该名称是该范围的扩展密钥，使得由源和目的地建立的协商映射基于与扩展相关联的扩展密钥。

Abstract: A technique improves efficiency of a copy-on-write (COW) operation used to create a snapshot and/or clone by a volume layer of a storage input/output (I/O) stack executing on one or more nodes of a cluster. The snapshot/clone may be represented as an independent volume, and embodied as a respective read-only copy (snapshot) or read-write copy (clone) of a parent volume. Volume metadata managed by the volume layer is organized as one or more multi-level dense tree metadata structures, wherein each level of the dense tree includes volume metadata entries for storing the metadata. The volume metadata entries may be organized as metadata pages having associated metadata page keys. Each metadata page is rendered distinct or “unique” from other metadata pages in an extent store layer of the storage I/O stack through the use of a multi-component uniqifier contained in a header of each metadata page. To improve the efficiency of the COW operation, the technique allows the use of reference count operations on the metadata page keys of the “unique” metadata pages so as to allow sharing of the metadata pages individually between the parent volume and the snapshot/clone.

Abstract translation: 一种技术提高了用于通过在集群的一个或多个节点上执行的存储输入/输出（I / O）堆栈的卷层创建快照和/或克隆的写时复制（COW）操作的效率。 快照/克隆可以表示为独立卷，并体现为父卷的相应只读副本（快照）或读写副本（克隆）。 由卷层管理的卷元数据被组织为一个或多个多级密集树元数据结构，其中密集树的每个级别包括用于存储元数据的卷元数据条目。 卷元数据条目可以被组织为具有相关联的元数据页面密钥的元数据页面。 每个元数据页面通过使用包含在每个元数据页面的报头中的多组件单元格，在存储I / O堆栈的盘区存储层中与其他元数据页面呈现不同或“唯一”。 为了提高COW操作的效率，该技术允许在“唯一”元数据页面的元数据页面键上使用引用计数操作，以便允许在父卷和快照/克隆之间单独共享元数据页面。

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 translation: 提供一个或多个技术和/或系统用于检测陈旧的数据和/或改变的数据。 例如，位图文件可以被维护并被映射到描述文件系统的各种文件状态的变体。 位图文件可以填充位图记录，指示文件是否被访问，修改或具有其他状态。 位图文件可以有效地传达用于确定文件是否最近没有被访问的信息（例如，陈旧的数据）或最近被修改（例如，改变的数据），因为位图文件可以包括大小的一小部分 （例如，一个字节的信息可以用于表示一个或多个文件的各种状态）。 以这种方式，可以评估位图文件而不是评估相对较大的内容，以便有效地识别用于删除或降级的陈旧数据和/或用于备份的改变的数据。
