QuestionQ16

Storage portfolio overview

When describing to a customer how the Data Protection Accelerator (DPA) on the HPE Alletra Storage MP X10000 scales, which design approach allows performance and capacity to be scaled independently of one another?

Explanation

The HPE Alletra Storage MP X10000 platform, including its Data Protection Accelerator nodes, is built on HPE's disaggregated NVMe architecture in which compute nodes and storage nodes/shelves are separate, independently addable components. Because compute (which drives performance) and storage media (which drives capacity) are decoupled, customers can add compute nodes to increase throughput/performance or add storage shelves to increase capacity without needing to scale the other resource in lockstep. This avoids the over-provisioning and rebalancing overhead typical of tightly coupled, integrated appliance designs, and is the specific architectural reason the platform can grow linearly in performance while capacity scales separately from terabytes up to exabytes.
