IBM Power S1122

Why IBM Power S1122?

Mid-range is the sweet spot for most organizations. Entry-level too small for production. Enterprise-class too expensive for medium workloads. Headroom needed for growth. Full virtualization capabilities required.

IBM Power S1122 is mid-range Power10 with optimal balance. 4-22 cores - flexibility for varied workloads. 4 TB RAM - serious memory for databases. Full PowerVM - enterprise virtualization. 2U footprint - space efficient.
