The PowerStore system is a midrange storage product with a container-based active/active architecture. PowerStore supports the latest storage media, such as NVMe SCM, NVMe SSDs, and NVMe NVRAM drives. This system is a highly available 2U two-node-based appliance that incorporates a flexible consumption model. The PowerStore system can scale out to up to four appliances (eight nodes) in a cluster and scale up to three expansion enclosures per appliance.
The PowerStore family consists of ten different models, from the PowerStore 500 model through the PowerStore 9200 model. PowerStoreOS 1.0 was launched with the PowerStore 1000T/X, 3000T/X, 5000T/X, 7000T/X, and 9000T/X models, while PowerStoreOS 2.0 introduced the entry-level 500 model. PowerStoreOS 3.0 introduced a platform refresh with the 1200T, 3200T, 5200T, and 9200T models. All PowerStore models use a common base enclosure and I/O modules, while differing by CPU core count and speed, memory size, and number of NVMe NVRAM drives. These hardware differences give each model a unique performance profile, scaling from entry-level to high-end.
Appliances in the PowerStore series are available in one of the following configurations:
Note: PowerStore X models are not certified for running SAP HANA in production at the time of publication. These models can be used for nonproduction SAP HANA systems.
Each of these configurations is available in different models with varying or expanding memory and CPU capabilities. See Table 1.
A PowerStore cluster combines multiple PowerStore appliances into a single grouping, which is managed as a single storage system. The cluster delivers aggregate performance from all appliances in the cluster, but a single volume is serviced by only one appliance at any given time. Volumes can be migrated between appliances in a cluster.
Note: A cluster must contain only PowerStore T appliances or only PowerStore X appliances; these models cannot be mixed within a single cluster.
Dell Technologies recommends that:
Clustering is applicable to block storage resources only. While a PowerStore T model in unified mode can serve as the cluster’s primary appliance, the file resources cannot migrate to a different appliance. When deploying multiple appliances for file access, plan to have multiple clusters.
The HTML5-based PowerStore Manager UI, as shown in the following figure, is the primary management tool for PowerStore configuration and administration.
The PowerStore system also supports management, configuration, and monitoring using the PowerStore command-line interface (PSTCLI) and a REST API. For relevant documentation, see the PowerStore Info Hub.
