Enterprise applications often face storage I/O and memory access bottlenecks, leading to over-provisioning of compute cores and increased software licensing costs. Google Cloud's new M4N machine series in Compute Engine is designed to address these challenges. These instances are purpose-built for I/O intensive, high-memory workloads, offering a significant advantage over competitors. M4N provides the highest per-core IOPS and throughput for high-memory instances. It also offers over a 20% total cost of ownership reduction for Oracle databases.The M4N instances feature higher memory ratios, up to 26:1, and can scale up to 6TB of memory. Powered by Intel's 5th Gen Xeon Scalable processors and Google Cloud's custom Titanium offload architecture, they deliver exceptional host storage performance. When paired with Hyperdisk Extreme, M4N instances achieve up to 25 GiB/s of aggregate storage performance and 1 million IOPS. This new offering complements existing memory-optimized families, specifically targeting storage and network bottlenecks.M4N is ideal for mission-critical databases, generative AI data layers, enterprise healthcare, and real-time analytics. Its high memory-to-core ratio allows for rapid data ingestion and zero-stall backup cycles. The instances also support sub-millisecond similarity searches for massive vector indexes and 400 Gbps network bandwidth. This capability is crucial for distributed model retrieval in generative AI.For enterprise healthcare and ERP systems, M4N ensures sustained I/O headroom, preventing latency spikes during peak usage. This is vital for applications like Epic Systems and SAP S/4HANA. Real-time analytics and Electronic Design Automation benefit from high memory capacity and maximum storage bandwidth for loading massive datasets. This allows for efficient checkpointing and in-memory processing.The M4N instances significantly optimize Oracle licensing costs by enabling right-sizing of infrastructure. Enterprises can reduce over-provisioning of cores while still meeting performance density requirements. This leads to a substantial TCO reduction compared to other hyperscalers. With more memory per core, larger portions of databases can reside in the system global area, reducing expensive I/O operations.Early customer experiences highlight M4N's role in transforming workloads by delivering high throughput across various instance sizes. The new compute platform demonstrates potential for scalable, resilient, and performant enterprise Oracle deployments. M4N bridges the gap between large memory footprints and extreme I/O performance, minimizing bottlenecks without additional infrastructure. This makes it a powerful solution for demanding data environments. The M4N instances are now available in select regions globally.
