M4N VM family, now GA: Highest per-core IOPS and throughput for I/O and memory-bound workloads

As enterprise organizations scale mission-critical applications, storage I/O and memory access can become severe operational bottlenecks. Whether its Oracle databases, in-memory databases like SAP HANA, or high-throughput SQL Server clusters, EHR systems, and real-time big data analytics, memory-bound databases often force enterprises to over-provision compute cores (vCPUs) to get the RAM capacity and storage bandwidth they need, driving up costly third-party software licensing fees.

Today, we are thrilled to announce the general availability of the M4N machine series in Google Compute Engine, purpose-built for I/O intensive, high-memory workloads, the second offering in our network- and block-storage optimized VM family. Compared to similar offerings from other hyperscalers M4N provides the highest per-core IOPS and throughput for high-memory instances, and over 20% TCO reduction for Oracle databases.

M4N is also the industry’s first instance of network and block storage optimized with higher memory ratios (up to 26:1) and size (6TB). Powered by 5th Gen Intel® Xeon® Scalable processors and built on Google Cloud’s custom Titanium offload architecture, M4N instances deliver up to 25,000 MiB/s (25 GiB/s) of aggregate host storage performance and up to 1 million IOPS when paired with Hyperdisk Extreme — doubling the block storage performance of current M4 instances.

M4N targets workloads that demand both extreme high-density RAM and uncompromising I/O performance, complementing our existing memory-optimized families (such as M1, M2, M3, M4, and X4) by solving specific storage and network bottlenecks for high-throughput enterprise applications.

Built for demanding workloads

Optimizing Oracle licensing costs

Enterprise IT departments struggle with the rising cost of core-based software licensing. For workloads like Oracle database, licensing fees are typically calculated based on the number of vCPUs or physical cores assigned to the instance. Historically, this has forced a difficult trade-off: paying for more compute cores than necessary just to obtain the required amount of RAM and storage performance.

M4N changes this paradigm with its industry-leading high memory-to-vCPU ratio. By providing the highest per-core IOPS and throughput for high-memory instances of all the leading hyperscalers, M4N allows database administrators to:

• Reduce TCO and licensing overhead: Stop over-provisioning of cores while meeting Oracle database performance density requirements, resulting in over 20% TCO reduction compared to similar offerings from leading hyperscalers.

• Right-size infrastructure: Allocate the exact amount of compute power needed for the workload while still accessing massive memory pools.

• Improve cache-hit ratios: With more memory available per core, larger portions of the database can reside in the system global area (SGA), reducing expensive I/O operations and further boosting efficiency.

What customers are saying

Early experiences with M4N show that workload-optimized infrastructure is the engine for transformation. 

“Before M4N, meeting our demanding I/O requirements on Google Cloud often required over-provisioning our compute to achieve the necessary performance density. The new M4N instances solve this by delivering high throughput across the smaller to larger shapes.” – Sherri Trojan, Sr Principal Solution Architect, Sabre

“We are delighted to see Google Cloud introduce this next-generation high-performance infrastructure for mission-critical database workloads. The new compute platform demonstrates tremendous potential for enterprise Oracle deployments requiring scalability, resiliency, and performance. We are excited about what this innovation means for customers running Oracle workloads on Google Cloud.” – Bala Kuchibhotla, Co-Founder and CEO, Tessell

“With M4N, Google Cloud continues to push the boundaries of platform co-design. By combining 5th Gen Intel Xeon Scalable processors with Google’s custom Titanium offload architecture, M4N delivers the extreme memory capacity, high memory bandwidth, and uncompromising I/O throughput required for the world’s most demanding mission-critical data environments.” –  Intel

What’s new: Scaling extreme data layers with M4N

M4N bridges two previously separate paradigms in cloud infrastructure: large memory footprints and extreme I/O performance. Engineered with custom Titanium offloads, M4N minimizes I/O bottlenecks without requiring infrastructure add-ons or compromises on memory density. Let’s take a look at how M4N fits into these environments. 

1. Enabling high bandwidth data transfer

For workloads with large memory footprints, M4N provides: 

• Superior VM-to-VM bandwidth: Delivers up to 400 Gbps aggregate VM-to-VM network bandwidth and up to 50 Gbps single-flow bandwidth within the same VPC, unlocking non-blocking data exchange for distributed database clusters and real-time streaming data layers.

• Enhanced internet and egress throughput: Enjoy up to 200 Gbps internet egress bandwidth and up to 48 MPPS packet processing performance.

• High bandwidth out-of-the-box: Achieve full performance without needing to purchase or configure premium Tier_1 networking add-ons.

2. Dynamic storage performance with Hyperdisk

Paired with Google Cloud’s next-generation storage portfolio, M4N with Hyperdisk lets you independently tune IOPS, throughput, and capacity:

• Hyperdisk Extreme (HdX): Delivers up to 25 GiB/s aggregate block storage throughput and 1,000,000 IOPS—double the storage performance of standard M4. This is great for rapid database recovery, transactional checkpointing, and instant in-memory index reloads.

• Hyperdisk Balanced (HdB): Scales up to 20 GiB/s throughput and 640,000 IOPS for cost-effective enterprise storage at scale.

M4N machine types and specifications

M4N instances are offered across three distinct memory-to-vCPU ratio tiers, scaling from 16 to 224 vCPUs and up to 5,952 GB of DDR5 RAM. M4N also offers predefined VM shapes across three distinct memory-to-vCPU ratios to match specific workload requirements, with support for Resource-based Committed Use Discounts (CUDs).  Details here.
