Dell EMC announced the midrange unified storage system called PowerStore in May of 2020. In 2021, Dell EMC announced an additional PowerStore model targeted at entry level enterprise. The Dell EMC PowerStore system is derived from elements of earlier midrange storage platform and new functionality including the ability to run applications on the storage system. The operating environment is called PowerStoreOS and is deployed on purpose-built hardware in two different ways: one is native on the bare metal hardware and is designated by T as a suffix of the product model and the other installs in a VM with VMware ESXi running on the PowerStore hardware, designated with an X suffix. Multiple models of PowerStore vary by the amount of cache and the type of processor. All modes use solid state devices of flash or SCM Optane and devices in the base controller enclosure use NVMe protocol. All models can scale out to four pairs of nodes of the same T or X model type. T models offer unified block and file with NAS support.
The PowerStore 500 model was added by Dell EMC in 2021 as an entry level addition to the PowerStore family. Unlike the other models, PowerStore 500 is available as a T model only. PowerStore 500 can scale out in a cluster of up to 4 appliances, or mixed with other T models.
Many of the software functions of the Dell EMC PowerStore systems were extracted from Unity software and PowerStoreOS is a container-based operating environment. PowerStore systems use a SuSE Linux kernel and support Docker containers. The filesystem software in the T models support multiple NAS Servers, which were previously called virtual data movers. PowerStore Manager is the element manager, deployed as a web GUI, implemented with HTML5.
The dual controllers are packaged in a 2U enclosure along with up to 21 NVMe protocol 2.5” devices and 2 to 4 NVRAM modules depending on the model. Additional devices that are SAS attached can be added with up to three additional enclosures. Software features are included in the base price and include snapshots, asynchronous remote replication, VVOLs and VASA support. Telemetry data is collected and analyzed with a SaaS product called CloudIQ. Health checks are done and proactive maintenance is scheduled based on the analytics.
The SSDs in PowerStore have a lifetime warranty as long as a maintenance contract is in place. In addition, the maintenance price is guaranteed not to be increased from the initial purchase.
