AWS Service: Amazon EC2 X2idn/X2iedn Instances
Question: How do X2idn/X2iedn Instances handle data transfer between the instance and storage services such as Amazon EBS or Amazon S3, and what architectural features enable high throughput and low-latency data access?
Answer:
X2idn/X2iedn Instances are optimized for high-performance computing and memory-intensive workloads and have several architectural features that enable high throughput and low-latency data access to storage services such as Amazon EBS or Amazon S3. Here are some key architectural features that contribute to this:
High-bandwidth networking: X2idn/X2iedn Instances are built on a high-performance networking architecture that includes multiple 100 Gbps network interfaces, which provides high-bandwidth and low-latency connectivity to storage services such as Amazon EBS or Amazon S3. This enables data to be transferred quickly and efficiently between the instance and storage services.
Non-uniform memory access (NUMA) architecture: X2idn/X2iedn Instances are designed with a NUMA architecture, which optimizes memory access by allocating memory that is closer to the processor. This architecture helps minimize data transfer across the system, reducing latency and improving performance.
Local storage options: X2idn/X2iedn Instances come with local NVMe SSD storage that provides high-speed storage directly attached to the instance, which can be used to store frequently accessed data. This reduces the need to transfer data between the instance and storage services such as Amazon EBS or Amazon S3.
Elastic Fabric Adapter (EFA): X2idn/X2iedn Instances are equipped with an Elastic Fabric Adapter (EFA) that provides high-speed, low-latency interconnectivity between instances in a cluster. EFA is specifically designed for HPC workloads and can provide up to 100 Gbps of network bandwidth, reducing latency and improving performance for data transfer between instances.
Enhanced networking: X2idn/X2iedn Instances support enhanced networking, which provides higher packet-per-second (PPS) performance, lower network jitter, and lower latencies. This enables more efficient use of network resources and faster data transfer between the instance and storage services.
Overall, the combination of high-bandwidth networking, NUMA architecture, local storage options, EFA, and enhanced networking in X2idn/X2iedn Instances enables high throughput and low-latency data access to storage services such as Amazon EBS or Amazon S3, making them ideal for high-performance computing and memory-intensive workloads.
