Amazon EC2 R6i Instances

Memory-optimized instances powered by 3rd Generation Intel Xeon Scalable processors

Get started with Amazon EC2 R6i instances

Amazon Elastic Compute Cloud (Amazon EC2) R6i instances, powered by 3rd Generation Intel Xeon Scalable processors, deliver up to 15% better price performance compared to R5 instances. R6i instances feature an 8:1 ratio of memory to vCPU, similar to R5 instances, and support up to 128 vCPUs per instance, which is 33% more than R5 instances. These instances are SAP-Certified and are an ideal fit for memory-intensive workloads (SQL and NoSQL databases), distributed web scale in-memory caches (Memcached and Redis), in-memory databases (SAP HANA), and real-time big data analytics (Apache Hadoop and Apache Spark clusters).

R6id instances come with local NVMe-based solid state drive (SSD) block-level storage for applications that need high-speed, low-latency local storage. Compared to previous generation R5d instances, R6id instances offer 58% higher TB storage per vCPU and 34% lower cost per TB.

R6in and R6idn instances offer up to 200 Gbps of network bandwidth and up to 2x higher packet-processing performance than R5n and R5dn instances. These instances also deliver up to 100 Gbps bandwidth and up to 400K IOPS of Amazon Elastic Block Store (EBS) performance, the fastest block-storage performance on EC2. You can scale the performance and throughput of network-intensive workloads, such as SQL and NoSQL databases, and in-memory databases, such as SAP HANA.

R6in and R6idn instances now available

Sixth-generation memory-optimized instances are now available with up to 200 Gbps bandwidth, up to 4x faster than R6i instances. Provide faster transfers and communication for your network-intensive workloads.

Benefits

Lower total cost of ownership

R6i instances deliver up to 15% better price performance than R5 instances. R6i instances also offer larger sizes, with up to 128 vCPUs and 1024 GiB of memory that you can use to consolidate workloads on fewer instances.

Flexibility and choice

R6i instances add to the broadest and deepest selection of EC2 instances on AWS. They provide 10 different instance sizes that feature varying amounts of vCPU, memory, networking, and storage. You can run a broad range of memory-intensive workloads.

Maximized resource efficiency

R6i instances are built on the AWS Nitro System, a combination of dedicated hardware and lightweight hypervisor. The Nitro System delivers practically all of the compute and memory resources of the host hardware to your instances for better overall performance and security.

Features

Powered by 3rd Generation Intel Xeon Scalable processors

R6i instances are powered by 3rd Generation Intel Xeon Scalable processors (Ice Lake) with an all-core turbo frequency of 3.5 GHz and include support for always-on memory encryption using Intel Total Memory Encryption (TME). R6i instances also support new Intel Advanced Vector Extensions (AVX-512) instructions for faster processing of cryptographic algorithms.

High-performance interfaces

R6in and R6idn instances offer up to 200 Gbps networking, up to 2x higher than R5n and R5dn instances. R6in and R6idn instances also deliver up to 100 Gbps bandwidth to Amazon Elastic Block Store (EBS), up to 1.6x higher than R5b instances. R6i instances provide up to 20% higher memory bandwidth per vCPU compared to R5 instances. You can also enable Elastic Fabric Adapter (EFA) in R6i, R6id, R6in, and R6idn instances on the 32xlarge and metal sizes.

High-speed, low-latency local storage

R6id and R6idn instances are equipped with up to 7.6 TB of local NVMe-based SSD block-level storage, and deliver up to 15% better price performance compared to previous generation instances. R6id are ideal for a wide range of memory-intensive workloads, including those that need access to high-speed, low- latency local storage.

*For 32xlarge and metal sizes, at least 2 elastic network interfaces, with each attached to a different network card, are required on the instance to achieve 200 Gbps throughput. Each network interface attached to a network card can achieve a maximum of 170 Gbps. For more information, see Network cards.
