HPE Q1J01A MSA 2050 SAN Dual Controller SFF Storage Array
Overview
The HPE Q1J01A is a dual-controller entry SAN array in the MSA 2050 family, built for small to medium-sized deployments that need both simplicity and flexibility. The system comes in a 2U chassis configured for up to 24 hot-plug 2.5″ SFF drives, making it suitable for application acceleration, virtualization hosts, remote/branch sites or departmental datacentre tiers. With either Fibre Channel (4 ports per controller at 16 Gb / 8 Gb) or iSCSI (4 ports per controller at 1 Gb / 10 Gb) host connectivity, you can match your network infrastructure while preserving investment in drives and enclosures.Despite its entry positioning, the MSA 2050 architecture supports advanced features such as thin provisioning, online controller upgrades (data-in-place migration from legacy arrays), snapshots, replication and hybrid flash configurations.In real-world terms, deploying the Q1J01A means you mount the 2U chassis in your rack, attach dual controllers for redundancy, choose FC or iSCSI host interface modules, install your drives (SAS SSD, SAS HDD or SAS Midline HDD), and manage it via the built-in GUI. It gives you a cost-effective storage foundation that can scale via additional enclosures as demands grow.
Key Features
Dual-controller architecture ensures availability and serviceability×controllers can be replaced online.
Up to 24 hot-plug SFF drive bays in a 2U chassis enables high drive density and flexible tiering (SSD + HDD mix).
Choice of host interface: FC (16 Gb/8 Gb) or iSCSI (10 Gb/1 Gb) ports at 4 per controller for SAN connectivity.
Support for advanced storage features: thin provisioning, automated tiering, snapshots, and remote replication×all in an "entry" price class.
Data-in-place upgrade path preserves investment: you can reuse enclosures or drives from earlier MSA models and migrate into new ones without full data re-write.
