HPE Alletra Storage MP B10000 vs Dell PowerStore

The B10000 uses a disaggregated, scale-out architecture that separates compute from storage so each scales independently, and it carries a 100% data availability guarantee. PowerStore uses paired active/active dual-node appliances that scale up internally and scale out as a federated cluster. The B10000 is built for independent scaling and availability assurance; PowerStore favors a simple, unified all-in-one design.

Both are end-to-end NVMe arrays with very low latency. The B10000's all-active design keeps every controller, host port, and drive engaged in I/O processing, which helps sustain consistent performance under heavy consolidation. PowerStore's active/active dual-node design is also strong, and real-world results depend on workload, data reduction, and configuration, so we recommend sizing both for your specific I/O profile.

HPE markets the B10000 as the industry's first disaggregated scale-out block array with a 100% data availability guarantee, underpinned by full hardware redundancy and a separate instance of ArcusOS running on each controller node. Dell positions PowerStore as designed for 99.9999% (six-nines) availability. The guarantees are contractual commitments with specific terms, so review the SLA language for either platform.

Both run always-on inline deduplication and compression. Dell publishes an industry-leading 6:1 data reduction guarantee on reducible data with no assessment or signature required. HPE backs the B10000 with its own storage efficiency guarantee. Achievable ratios vary by data type, so neither number should be read as a promise for your specific dataset.

PowerStore has deep VMware integration, including vVols and AppsON for hosting VMs directly on the array, which appeals to vSphere-centric shops. The B10000 also integrates well with VMware and adds independent scaling and the availability guarantee. For pure general-purpose VM consolidation PowerStore is a natural fit; for mission-critical VMs that must never go offline the B10000's architecture has the edge.

Yes. As an authorized HPE reseller we can source the HPE Alletra Storage MP B10000 as a TAA-compliant configuration through vehicles such as GPC, SAP, and FAR, and Dell PowerStore is likewise widely available on federal contracts. PowerStore's STIG-hardened OS can help with accreditation. Tell us your contract vehicle and we can quote either array accordingly.

Yes. Both support NVMe-oF for low-latency host connectivity. PowerStore supports NVMe-oF over both Fibre Channel and TCP, and the B10000 supports NVMe-oF alongside traditional FC and iSCSI. The right transport depends on your existing fabric and host stack.

The B10000 is tightly integrated with HPE GreenLake for pay-per-use block storage and unified hybrid cloud operations, while PowerStore is available through Dell APEX subscriptions. If you want consumption pricing as part of a broader hybrid cloud estate, the B10000 with GreenLake is the more cohesive option; PowerStore via APEX is a solid choice within a Dell-centric environment.
