Data protection using intra-device parity and intra-device parity
A system and method for offset protection data in a RAID array. A computer system comprises client computers and data storage arrays coupled to one another via a network. A data storage array utilizes solid-state drives and Flash memory cells for data storage. A storage controller within a data storage array is configured to store user data in a first page of a first storage device of the plurality of storage devices; generate intra-device protection data corresponding to the user data, and store the intra-device protection data at a first offset within the first page. The controller is further configured to generate inter-device protection data corresponding to the first page, and store the inter-device protection data at a second offset within a second page in a second storage device of the plurality of storage devices, wherein the first offset is different from the second offset.
CONDITIONAL ROLE DECISION BASED ON SOURCE ENVIRONMENTS
Example implementations can involve a system, which can involve a server configured to distribute role decision condition expressions created based on user input to one or more storage devices; and the one or more storage devices, which can involve a processor, configured to, for receipt of a request, determine user identification information, request source environment information and requested contents from the request; determine a role from the role decision condition expressions based on the user identification information and request source environment information; and determine whether or not the request can be executed based on the role.
Servicing input/output (‘I/O’) operations during data migration
Volume migration among a set of storage systems synchronously replicating a dataset for a volume, where volume migration includes: initiating a transfer of the volume in dependence upon determining that a performance metric for accessing the volume stored on a first storage system would improve if transferred to a second storage system; and during the transfer of the volume: determining status information for the transfer; intercepting an I/O operation directed to the volume; and directing, in dependence upon the status information, the I/O operation to either the first storage system or the second storage system.
Baseboard-management-controller storage module
A system including a baseboard management controller (BMC) and a socket is described. The BMC is configured to provide a management interface to a network device. The socket is configured to accept an edge connector of a removable storage card. The BMC is configured to access via the socket at least a portion of the firmware of the BMC stored on the removable storage card.
Storage volume regulation for multi-modal machine data
A network storage volume stores first entries in a first-mode storage bucket and a second entries in a second-mode storage bucket. The first-mode storage bucket has first bucket metadata, and the second-mode storage bucket has second bucket metadata. A computer-implemented method includes comparing a utilized capacity of the network storage volume to a target capacity information of the network storage volume to obtain a comparison result. Based on the comparison result, at least one bucket is selected to be purged from the buckets of the network storage volume based at least in part on bucket metadata of the buckets. The method further includes causing a purge of the at least one selected bucket from the network storage volume.
Volume remote copy based on application priority
Example implementations described herein involve systems and methods which automatically determine volumes to be replicated for disaster recovery based on the execution priority of an application which uses the volumes. Such example implementations can involve systems and methods involving creating a volume in a first storage system for each of one or more containers newly launched on one or more servers managing a container orchestrator; and establishing replication of the volume for the each of the newly launched one or more containers to a second storage system in order from highest container priority to lowest container priority.
Multi-tenant storage
A system, apparatus and product comprising: a multi-tenant layer that comprises shared resources, wherein the shared resources are accessible to multiple tenants of the storage system, wherein the shared resources comprise shared logic resources and shared data resources; and multiple single-tenant layers, wherein each single-tenant layer is associated with a respective tenant of the multiple tenants, wherein each single-tenant layer comprises a database and business logic of the respective tenant, wherein a multi-tenant encryption scheme is configured to enable secure communications with the multiple tenants without divulging sensitive information to the multi-tenant layer.
Virtualized file server smart data ingestion
In one embodiment, a system for managing a virtualization environment includes a set of host machines, each of which includes a hypervisor, virtual machines, and a virtual machine controller, and a data migration system configured to identify one or more existing storage items stored at one or more existing File Server Virtual Machines (FSVMs) of an existing virtualized file server (VFS). For each of the existing storage items, the data migration system is configured to identify a new FSVMs of a new VFS based on the existing FSVM, send a representation of the storage item from the existing FSVM to the new FSVM, such that representations of storage items are sent between different pairs of FSVMs in parallel, and store a new storage item at the new FSVM, such that the new storage item is based on the representation of the existing storage item received by the new FSVM.
Partial save of memory
A variety of applications can include systems and/or methods of partial save of memory in an apparatus such as a non-volatile dual in-line memory module. In various embodiments, a set of control registers of a non-volatile dual in-line memory module can be configured to contain an identification of a portion of dynamic random-access memory of the non-volatile dual in-line memory module from which to back up content to non-volatile memory of the non-volatile dual in-line memory module. Registers of the set of control registers may also be allotted to contain an amount of content to transfer from the dynamic random-access memory content to the non-volatile memory. Additional apparatus, systems, and methods are disclosed.
Refresh counters in a memory system
Methods, systems, and devices for refresh counters in a memory system are described. In some examples, a memory device may include two or more counters configured to increment a respective count based on refresh operations performed on a memory array. A comparison may be made between two or more of the respective counts, which may include determining a difference between the respective counts or a difference in rate of incrementing. A memory device may transmit an indication to a host device based on determining a difference between counters, and the memory device, the host device, or both, may perform various operations or enter various operational modes based on the determined difference.
