IBM Power S1124

Why IBM Power S1124?

Largest scale-out workloads require serious horsepower. Mid-range often too small for production databases. Enterprise systems are overkill for departmental. Two-socket architecture offers optimal price/performance. Scale-out clusters need dense nodes.

IBM Power S1124 is largest scale-out Power10 with maximum flexibility. 8-48 cores - highest density in scale-out. 8 TB RAM - serious memory for large databases. 2-socket - optimal price/performance. Full PowerVM with enterprise features.
