As small-to-medium businesses (SMBs) faced 53% annual data growth and 68% of IT teams struggled with outdated infrastructure in the mid-2010s, HPE’s ProLiant ML30 and DL20 Gen9 servers emerged as game-changers. These platforms redefined cost-efficient scalability, offering enterprise-grade features at SMB budgets. This analysis uncovers how these servers became the backbone of modern SMB operations, combining raw power with smart management in compact form factors.
The Gen9 ProLiant series marked a turning point in server design—35% smaller than previous generations yet packing 2.7x the compute density. Released during the critical transition to hybrid cloud and NVMe storage, these servers addressed key SMB pain points: budget constraints, limited IT expertise, and unpredictable workload demands.
