Hewlett Packard Enterprise Q1J31A Storage System

The Hewlett Packard Enterprise Q1J31A/Q1J31B MSA 2052 SAS dual‑controller storage system is a high‑performance, scalable shared storage solution designed for enterprise data centers and virtualization environments that require reliable data management and redundancy. Housed in a 2U rack, it supports 2.5" SAS drives and 12Gb SAS storage interfaces to deliver fast data throughput, with dual active/active controllers and an integrated controller cache (model dependent) to sustain demanding workloads. It supports expansion enclosures to scale capacity and offers multiple RAID levels for data protection and performance tuning. Connectivity options vary by configuration and can include SAS, FC, or iSCSI host interfaces to fit diverse data center architectures. Redundancy is built in with dual controllers, redundant power supplies, and cooling, while a web‑based management interface simplifies monitoring and configuration. In enterprise environments, the MSA 2052 is commonly used for virtualized databases, backup and recovery, file storage, and other applications requiring reliable shared storage and continuous operation. Common replacements in data centers include HPE MSA 2060 and MSA 2042 storage arrays.
