You can now launch Amazon Redshift clusters on our second-generation Dense Compute (DC2) nodes. DC2 is designed for demanding data warehousing workloads that require low latency and high throughput. They feature powerful Intel E5-2686 v4 (Broadwell) CPUs, fast DDR4 memory, and NVMe-based solid state disks (SSDs). We’ve tuned Amazon Redshift to leverage the better CPU, network, and disk on DC2 nodes, providing up to twice the performance of DC1 at the same price. Our DC2.8xlarge instances now provide twice the memory per slice of data and an optimized storage layout with 30% better storage utilization.
If you have a DC1.Large Amazon Redshift cluster, you can simply restore to a new DC2.large cluster using an existing snapshot. To migrate from DS2.xlarge, DS2.8xlarge, or DC1.8xlarge Amazon Redshift clusters, you can use the resize operation to move data to your new DC2 cluster. For more information, see Clusters and Nodes in Amazon Redshift.
DC2 nodes are available in US East (N. Virginia), US East (Ohio), US West (N. California), US West (Oregon), EU (Frankfurt), EU (Ireland), EU (London), Asia Pacific (Singapore), Asia Pacific (Tokyo), Asia Pacific (Sydney), Asia Pacific (Seoul), Asia Pacific (Mumbai), Canada (Central), and South America (São Paulo) Regions, including Amazon Web Services China (Beijing) Region, operated by Sinnet.
