You are working with a local hospital to update their aging storage environment, which uses mid- range arrays. The hospital has a limited budget and is very concerned with availability and security Wh

The HP P9500 is a high-end enterprise array whose cost would exceed a limited hospital budget, making it an impractical choice regardless of its security features.

The HP StoreServ 7200 with Proactive Care adds a support service tier for availability but omits SED, leaving the security requirement unaddressed for a healthcare environment.

The HP StoreServ 7400 is a mid-range array that fits within a limited budget while the Self-Encrypting Drives (SED) provide hardware-level data-at-rest encryption essential for healthcare regulatory compliance and data security. The Dual Mirror Rebuild (DMR) feature significantly reduces vulnerability windows during drive rebuilds, directly addressing the hospital's availability requirements, and the 4-node configuration adds controller-level redundancy.

HP StoreVirtual with Network RAID-10 and DMR is a software-defined scale-out solution targeting different workload tiers and does not directly replace mid-range arrays or meet the targeted security posture required by the hospital.
