Platform
PowerStore Family
PowerStore is a 2U, two node, purpose built platform that ranges from the PowerStore 500 up to the new PowerStore 9200. The two model types (PowerStore T and PowerStore X) are denoted by the letter T or X at the end of the model number. In PowerStoreOS 3.0, four new PowerStore T models have been introduced, ranging from PowerStore 1200T up to PowerStore 9200T. These appliances feature the same dual-node architecture with upgraded dual-socket Intel® Xeon® processors and are supported on PowerStoreOS 3.0 and higher software.
The following two tables outline the next generation PowerStore models, including the PowerStore 500 and the new 1200-9200 models (Table 1), and the original PowerStore models available at the launch of PowerStoreOS 1.0 (Table 2).

NVMe Expansion Enclosure
Starting In PowerStoreOS 3.0, the PowerStore 500, 1200, 3200, 5200, and 9200 model systems support 24-drive 2U NVMe expansion enclosures (see Figure 1) using 2.5-inch NVMe SSD drives for extra capacity. NVMe expansion enclosures do not support NVMe SCM drives. The base enclosure can support all NVMe SSDs or a mix of NVMe SSDs and NVMe SCM drives (for meta data tier) with an NVMe expansion enclosure attached. Prior to attaching an NVMe expansion enclosure, all drive slots 0 to 21 in the base enclosure must be populated. Each appliance in a PowerStore cluster supports up to three NVMe expansion enclosures.
This enables each appliance to scale to over 90% more expansion capacity when compared to using a SAS expansion enclosure. The NVMe expansion enclosure (as shown here) can result in a 66% increase in the maximum effective capacity of a cluster. PowerStore can now support over 18 PBe capacity on each cluster!
100 GbE Front End Connectivity
PowerStoreOS 3.0 also introduces a new 100 GbE optical I/O module that supports QSFP28 transceivers running at 100 GbE speeds. The 100 GbE I/O module must be populated into I/O module slot 0 on each node of the PowerStore appliance. This I/O module supports file, NVMe/TCP, iSCSI traffic, replication, and import interfaces.
Data mobility
Metro Volume
PowerStoreOS 3.0 and higher supports synchronous block replication with the Metro Volume feature. Metro Volume can be used for disaster avoidance, application load balancing, and migration scenarios. This provides active-active IO to a metro volume spanned across two PowerStore clusters. It supports FC or iSCSI connected VMware ESXi hosts for VMFS datastores. A Metro Volume can be configured easily and quickly in as little as six clicks!
File Replication
Starting with PowerStoreOS 3.0, asynchronous file replication is now available. Asynchronous replication can be used to protect against a storage-system outage by creating a copy of data to a remote system. Replicating data helps to provide data redundancy and safeguards against failures and disasters at the main production site. Having a remote disaster recovery (DR) site protects against system and site-wide outages. It also provides a remote location that can resume production and minimize downtime due to a disaster.
vVol Replication
PowerStoreOS 3.0 brings support for asynchronous replication for vVol-based virtual machines. This feature uses VMware Storage Policies and requires VMware Site Recovery Manager instances at both sites. Asynchronous replication for vVol-based VMs uses the same snapshot-based asynchronous replication technology as native block replication.
Enterprise File
Common Event Publishing Agent (CEPA)
PowerStoreOS 3.0 introduces Common Event Publishing Agent (CEPA). CEPA delivers SMB and NFS file and directory event notifications to a server, enabling them to be parsed and controlled by third-party applications. You can implement this feature for use cases such as detecting ransomware, monitoring user access, configuring quotas, and providing storage analytics. The event notification solution consists of a combination of PowerStore, the Common Event Enabler (CEE) CEPA software, and a third-party application.
File Level Retention (FLR)
PowerStoreOS 3.0 also introduces File-Level Retention (FLR). FLR is a feature that can protect file data from deletion or modification until a specified retention date. This functionality is also known as Write-Once, Read-Many (WORM).
PowerStore supports two types of FLR: FLR-Enterprise (FLR-E) and FLR-Compliance (FLR-C). FLR-C has other restrictions and is designed for companies that must comply with federal regulations. The following table shows a comparison of FLR-E and FLR-C.
Table 3. FLR-E and FLR-C
Name | FLR-Enterprise (FLR-E) | FLR-Compliance (FLR-C) |
Functionality | Prevents file modification and deletion by users and administrators through NAS protocols such as SMB, NFS, and FTP | |
Deleting a file system with locked files | Allowed (warning is displayed) | Not allowed |
Factory reset (destroys all data) | Allowed | |
Infinite retention period behavior | Soft: A file locked with infinite retention can be reduced to a specific time later | Hard: A file locked with infinite retention can never be reduced (an FLR-C file system that has a file locked with infinite retention can never be deleted) |
Data integrity check | Not available | Available |
Restoring file system from a snapshot | Allowed | Not allowed |
Meets requirements of SEC rule 17a-4(f) | No | Yes |
File On All Ports
Starting with PowerStoreOS 3.0, you can configure user-defined link aggregations for file interfaces. This ability enables you to create custom bonds on two to four ports. The bond can span the 4-port card and I/O modules, but these components must have the same speed, duplex, and MTU settings. These user-designed link aggregations support NAS server interfaces, and allow you to scale file out to any supported Ethernet port.
VMware Integration
VMware Visibility
PowerStore natively supports visibility into vVol datastores, pulling all virtual machines hosted on PowerStore vVol datastores into PowerStore Manager for direct monitoring. With the introduction of PowerStoreOS 3.0, this VMware visibility is expanded to include NFS and VMFS datastores backed by PowerStore storage. File systems and volumes on PowerStore that are configured as NFS or VMFS datastores in vSphere will reflect the datastore name within PowerStore Manager. Any virtual machine deployed on those datastores will also be captured in PowerStore Manager and visible from both the virtual machines page or within the resource details page itself.
VMware File System
Starting with PowerStoreOS 3.0, an option to create a VMware file system is added. VMware file systems are designed and optimized specifically to be used as VMware NFS datastores. VMware file systems support AppSync for VMware NFS, Virtual Storage Integrator (VSI), hardware acceleration, and VM awareness in PowerStore Manager.
NVMe Storage Containers
PowerStoreOS 3.0 adds support to create either SCSI or NVMe storage containers. Before this release, all storage containers were SCSI by default. SCSI storage containers support host access through SCSI protocols, which include iSCSI or Fibre Channel. NVMe storage containers support host access through NVMe/FC protocols and allow for vVols over NVMe/FC.
Security
KMIP
PowerStoreOS 3.0 supports using external key-management applications. External key managers for storage arrays provide extra protection if the array is stolen. The system does not boot and data cannot be accessed if the external key server is not present to provide the relevant Key Encryption Key (KEK).
FIPS
Data at Rest Encryption (D@RE) in PowerStore uses FIPS 140-2 validated self-encrypting drives (SEDs) by respective drive vendors for primary storage (NVMe SSD, NVMe SCM, and SAS SSD). PowerStoreOS 3.0 also supports FIPS 140-2 on the NVMe NVRAM write-cache drives. With PowerStoreOS 3.0, all PowerStore models can now be FIPS 140-2 compliant.
Native Import
PowerStoreOS 3.0 introduces native file import. This feature enables you to import file storage resources from Dell VNX2 to PowerStore. This feature enables administrators to import a Virtual Data Mover (VDM) along with its associated NFS or SMB file systems. The creation, monitoring, and management of the migration session is all completed by PowerStore and has a similar user experience to native block import.
PowerStore Manager
PowerStoreOS 3.0 added a number of enhancements and new features to PowerStore Manager to improve the usability and efficiency of the system. I’ve summarized some of the key features in the management space below:
- Host Information – Initiators: The new initiators pane added to the Host Information page displays all initiators and initiator paths in one pane of glass for all supported protocols (iSCSI, FC, NVMe/FC, and NVMe/TCP).
- Snapshots Column: This new column added for the volumes, volume groups, file systems, and virtual machine list pages allows you to easily see how many snapshots are associated with a particular object.
- View Topology: This feature provides a hierarchy as a graphical family tree, making it easy and efficient to visualize the family relationship of a volume or volume group, snapshots, and thin clones.
- Performance Metrics: New five-second metrics allow you to specify certain resources with enhanced granularity, and even compare up to 12 resources of the same type in a single window.
- Automatic Software Downloads: With support connectivity enabled, this feature automatically downloads software packages to PowerStore to make upgrades even easier.
- Language Packs: This feature translates texts and adds specific local components for different regions.
Conclusion
As you can see, PowerStoreOS 3.0 is a huge release delivering a new second generation platform refresh and a huge set of features to allow our customers to boost their performance, innovate without limits, and remain continuously modern with the PowerStore platform.
