New Storage-Optimized Amazon EC2 I4g Instances: Graviton Processors and AWS Nitro SSDs
- May 10, 2023
Today we are launching I4g instances powered by AWS Graviton2 processors that deliver up to 15% better compute performance than our other storage-optimized instances.
With up to 64 vCPUs, 512 GiB of memory, and 15 TB of NVMe storage, one of the six instance sizes is bound to be a great fit for your storage-intensive workloads: relational and non-relational databases, search engines, file systems, in-memory analytics, batch processing, streaming, and so forth. These workloads are generally very sensitive to I/O latency, and require plenty of random read/write IOPS along with high CPU performance.
Here are the specs:
|i4g.large||2||16 GiB||468 GB||up to 10 Gbps||up to 40 Gbps|
|i4g.xlarge||4||32GiB||937 GB||up to 10 Gbps||up to 40 Gbps|
|i4g.2xlarge||8||64 GiB||1.875 TB||up to 12 Gbps||up to 40 Gbps|
|i4g.4xlarge||16||128 GiB||3.750 TB||up to 25 Gbps||up to 40 Gbps|
|i4g.8xlarge||32||256 GiB||7.500 TB
(2 x 3.750 TB)
|18.750 Gbps||40 Gbps|
|i4g.16xlarge||64||512 GiB||15.000 TB
(4 x 3.750 TB)
|37.500 Gbps||80 Gbps|
The I4g instances make use of AWS Nitro SSDs (read AWS Nitro SSD – High Performance Storage for your I/O-Intensive Applications to learn more) for NVMe storage. Each storage volume can deliver the following performance (all measured using 4 KiB blocks):
Torn Write Protection is supported for 4 KiB, 8 KiB, and 16 KiB blocks.
I4g instances are available today in the US East (Ohio, N. Virginia), US West (Oregon), and Europe (Ireland) AWS Regions in On-Demand, Spot, Reserved Instance, and Savings Plan form.
