Abstract: Boot integrity of a storage platform is verified by comparing observed boot data values with expected boot data values stored in a secure remote cloud. The boot data values include hashes of software that runs at each stage of a boot sequence, e.g., BIOS, bootloader, kernel, and runlevel programs. The observed boot data values may be provided by a TPM using an AIK and nonce. If the observed boot data values fail to match the expected boot data values then a boot integrity service running on the storage platform limits functionality such as by disabling IO services, disabling remote data replication, enabling a diagnostic service, enabling a data collection service, disabling access by non-service accounts, and protecting a management database.

The processing device is also configured to detect one or more designated events affecting operation of the database system and, responsive to detecting at least one of the one or more designated events, to process one or more unsaved transactions of the database system utilizing the information stored in the set of one or more queues of the data store external to the database system.

Abstract: One or more embodiments of the invention have a cluster manager, or other related component, determine upfront which data node should perform a backup of the asset. This is achieved by running a pre-backup step, either periodically or prior to the reception of a backup request, to determine the preferred node for backup. Once the backup request is received, the cluster manager queries the preferred node, if the preferred node is still the best data node to perform the backup, then that data node performs the backup. If, however, the preferred data node no-longer is the best data node for performing the backup, the current preferred data node will signal the cluster manager with an alternative data node that is best data node to perform the backup and the cluster manager will have that alternative data node perform the backup.

The processing device is further configured to determine, based on the IO activity level of the given storage object and the determined write penalty, whether to move the given storage object from the first to the second storage tier and to move, responsive to an affirmative movement determination, the given storage object to the second storage tier.

The method includes populating one or more data structures based at least in part on the received inputs, aggregating edge resources of multiple ones of the edge computing sites into an edge network based at least in part on the populated data structures, and utilizing at least a portion of the aggregated edge resources of the edge network to execute at least a portion of a workload of a particular user.

Abstract: Currently, there is no scalable methodologies defined to locate a namespace on an NVMe-oF fabric. Therefore, it is necessary to configure a host with the NVMe™ Qualified Name (NQN) and transport information of the storage subsystem where the boot namespace is located or discover and enumerate all namespaces available to the host on an NVMe-oF fabric. With the current protocols, a host may need to perform many operations to locate the proper namespace and boot from the NVMe-oF fabric, making booting in a SAN environment an extremely slow operation and computationally expensive process. Embodiments herein support discovery, via a discovery controller, to provide a namespace resolution service able to facilitate a host to efficiently resolve a given namespace identifier to the corresponding subsystem port(s) through which that namespace is accessible.

Abstract: A software-defined, server-based storage system is configured to support single node granular scaling and adaptive RAID width capabilities. The storage system includes multiple homogeneous storage nodes, each including a server and local storage. Aggregate storage is organized into same-size cells. RAID group members are distributed in cells across storage nodes in a recursive fractal pattern. The storage system is scaled by metamorphosing between recursive fractal distribution of the RAID groups and linear distribution of the RAID groups and splitting matrices of cells. When a sufficient number of new storage nodes have been added, new larger width RAID groups will be formed.

Abstract: A configuration file specifies a percentage value of data to validate. A synthetic full backup image of a source volume on cloud storage is accessed. The synthetic full backup is created by merging changed blocks of an incremental backup with another previous backup. A bitmap specifying locations of the changed blocks is examined. A region on the synthetic full backup beginning at a location corresponding to an initial changed block and ending at a location corresponding to a last changed block according to the bitmap is identified. The region is partitioned into a set of portions. Each portion is validated by randomly selecting blocks in a respective portion to validate. The validating of the respective portion continues until an amount of data validated in the respective portion reaches a size equal to the percentage value of a size of the incremental backup divided by a number of portions.

Abstract: A storage system that includes multiple CPU hosts and PCI-E multi-host capable devices uses link selection controllers to map shared memory addresses to individual PCI-E links such that each address is accessed via only one of a plurality of PCI-E links. The addresses may be grouped into same-size segments, each of which contains only addresses mapped to the same PCI-E link. The link selection controllers monitor for state changes that affect PCI-E link availability and, in response to detection of a failure, coordinate a response that includes re-mapping the affected addresses.
