General purpose instance profiles - Gen 2

The general purpose 2nd generation virtual server profiles (balanced, compute, and memory) are available to provision virtual servers on both Intel and AMD processor architectures.

Intel profiles

The general purpose 2nd generation virtual server profiles (balanced, compute, and memory) are built atop the 2nd Generation Intel® Xeon® Scalable processors. They provide a broad set of capabilities and scale from 2 vCPUs (1 physical core) up to 128 vCPUs (64 physical cores).

The general purpose profiles can also be paired with a corresponding dedicated host. This solution allows for single-tenant hypervisors running workloads from a single IBM Cloud® account.

Limits

An instance has a limit for the number of volumes and virtual network interfaces that can be attached. This limit is based on the size of the instance.

General purpose profile family limits for vCPU, maximum volumes, and maximum network interfaces
Number of vCPUs	Max Volumes	Max vNICs
2-16	15	5
17-48	15	10
49+	15	15

Dedicated host profiles

Dedicated hosts allow users to provision a single-tenant host server and then provision virtual server instances of the corresponding family on the dedicated host.
