Dell PowerScale

Introduction

Dell PowerScale is a scale-out network-attached storage platform offered by Dell EMC for high-volume storage, backup and archiving of unstructured data. It provides a cluster-based storage array based on industry-standard hardware and is scalable to 50 petabytes in a single filesystem using its FreeBSD-derived OneFS file system. A PowerScale clustered storage system is composed of three or more nodes. Each node is a server integrated with proprietary operating system software called OneFS (based on FreeBSD), which unifies a cluster of nodes into a single shared resource.

Available resources under PowerScale are as follows:

Cluster : OneFS works exclusively with dedicated platform nodes, referred to as a cluster.
Node : A single cluster consists of multiple nodes, which are rack-mountable enterprise appliances containing: memory, CPU, networking, Ethernet or low-latency InfiniBandinterconnects, disk controllers and storage media. As such, each node in the distributed cluster has compute as well as storage or capacity capabilities.

Use Cases

Discovery

Discovers all the high-level components such as PowerScale Cluster, PowerScale Node, PowerScale Network Interface, PowerScale Drive, PowerScale Job, PowerScale Network Pool, PowerScale Quota, PowerScale SyncIQ Policy, PowerScale SnapShot, PowerScale Nfs Export, PowerScale Smb Share.
Publishes relationships between resources to enable a topological view and simplify maintenance
Refer to the Resource Hierarchyfor detailed structure.

Monitoring

Provides monitoring related to availability, capacity, performance, usage, thermal and power.
Alerts are generated when defined metric thresholds are breached, notifying users of potential issues.
Refer to the Supported Metrics and Default Monitoring Configuration.

Supported Target Versions

Integration Version History


Application Version	Bug fixes / Enhancements
7.2.0	Refactored alert/event polling in the application configuration UI to improve usability.
7.1.0	Introduced third-party CI alert mapping and OpsQL-based enhancements. Alert mappings can be configured to target CI systems through the application configuration, automatically forwarding alerts to the corresponding third-party platforms and mapping them to the specified CIs. Moved resource filtering in the application configuration from manual entry of resource core and custom attributes to OpsQL-based filtering, with keys auto-populated as needed.
7.0.1	Fixed redundant API calls to PowerScale devices during concurrent monitoring cycles by implementing proper cache synchronization. Added monitor-type filtering so Event and API Statistics monitors execute only their required API calls. Optimized cluster monitoring by using direct API calls instead of the bulk cache.
7.0.0	Updated resource moids by including the cluster GUID to avoid resource reconciliation issues for nodes and their child resources. Added support for the root resource UUID as a custom attribute, along with changes to metric data precision values. An issue with the below metrics monitoring was observed and has now been fixed. powerscale_node_AvgLatency powerscale_node_MaxLatency powerscale_node_MinLatency
6.0.0	Support provided for the metric powerscale_cluster_health_Status and metric computations corrected for PowerScale Node native Type.
5.0.3	Added support for the latest metrics, Activity Logger updates, and DebugHandler changes.
5.0.2	Fixed the issue caused due to jsonpath library version update and populated IO statistics metrics on "PowerScale Cluster" & "PowerScale Node" native types. Enhanced event processing logic to resolve correlation issue.
5.0.1	If Cluster and One of the node Ips matched then Updating the MAC address of cluster and that Node as CU:00:00:00:00:FirstTwoCharsOfSerialNumber and ND:00:00:00:00:FirstTwoCharsOfSerialNumber respectively.
5.0.0	Updated loggers from Error Level to Debug Level to minimize memory utilization. Metric Calculation correction for below metrics: powerscale_cluster_FreeCapacity powerscale_cluster_UsedCapacity powerscale_cluster_TotalCapacity powerscale_quota_NfsHard powerscale_storagepools_AvailBytes powerscale_storagepools_AvailHddBytes powerscale_storagepools_AvailSsdBytes powerscale_storagepools_FreeBytes powerscale_storagepools_FreeHddBytes powerscale_storagepools_FreeSsdBytes powerscale_storagepools_TotalBytes powerscale_storagepools_TotalHddBytes powerscale_storagepools_TotalSsdBytes powerscale_storagepools_UsableBytes powerscale_storagepools_UsableHddBytes powerscale_storagepools_UsableSsdBytes powerscale_storagepools_UsedHddBytes powerscale_storagepools_UsedSsdBytes powerscale_storagepools_VirtualHotSpareBytes powerscale_nodepools_AvailBytes powerscale_nodepools_AvailHddBytes powerscale_nodepools_AvailSsdBytes powerscale_nodepools_FreeBytes powerscale_nodepools_FreeHddBytes powerscale_nodepools_FreeSsdBytes powerscale_nodepools_TotalBytes powerscale_nodepools_TotalHddBytes powerscale_nodepools_TotalSsdBytes powerscale_nodepools_UsableBytes powerscale_nodepools_UsableHddBytes powerscale_nodepools_UsableSsdBytes powerscale_nodepools_UsedHddBytes powerscale_nodepools_UsedSsdBytes powerscale_nodepools_VirtualHotSpareBytes powerscale_node_TotalCapacity powerscale_node_FreeCapacity powerscale_node_UsedCapacity Corrected powerscale_bootDrive_LifeRemaining metric processing check at app-level. Support given to all the possible states for metric powerscale_drive_State. subCategory updated from Storage Management to Storage. Support for native type wise discovery. Setting aliasName for PowerScale Nodes with its Serial Number
