Amazon Elastic Block Store (Amazon EBS) provides storage volumes for use with EC2 instances which are deployed on Ansys Gateway.
EBS provides various volume types, which differ in performance characteristics and price. <\/p>\n
Here we are discussing general-purpose Solid-state drive (SSD) volumes. SSD-backed volumes are optimized for transactional workloads involving frequent read\/write operations with small I\/O size, where the dominant performance attribute is IOPS, and are suitable for Ansys workloads.<\/p>\n
General Purpose SSD volumes are offered in two types:<\/p>\n
Both balance price and performance, where gp3<\/strong> is the latest generation offered. gp2<\/strong> provides a maximum of 250MiB\/s throughput (with volumes that are 334 GiB and larger) , whereas gp3<\/strong> has the capability to provide throughput up to 1000 MiB\/s.<\/p>\n Table Summary volumes in the US East (N.

The main difference between the two is how performance is scaled:<\/p>\n\n
Volumes smaller than 1 TiB can also burst up to 3,000 IOPS for a limited period 30 minutes up to 2 hours depending on the disk size.<\/li>\n
Additionally gp3<\/strong> volumes offer a 20 percent lower price per GiB than gp2<\/strong> volumes.
It is possible to provision IOPS flexibly, so if more IOPS is required, modify it manually, this can be done using elastic volume operations described here:Amazon EBS Elastic Volumes – Amazon Elastic Compute Cloud<\/a><\/span><\/li>\n<\/ul>\n
