The scalability to meet growing demands

The System x3755 M3 is a four-socket server that provides outstanding performance and capacity in a data center-friendly 2U footprint. Based on the 4-, 8-, 12-core or 16-core AMD Opteron 6300 Series platform, the x3755 M3 helps organizations scale as workload demands increase, accommodating up to 64 processor cores and 512 GB of memory for cost-effective scaling.

The right size for midsized workloads

The x3755 M3 is an ideal server for business workloads including database, virtualization, Java, and enterprise applications such as ERP. The increased processor density helps reduce networking complexity and cost for high-performance computing environments, and the available 32 TB of internal storage facilitates data-intensive applications like business intelligence.
