High Memory instance profiles - Gen 2
The High Memory profiles include Very High Memory profiles and Ultra High Memory profiles. The Very High Memory family is optimized for running small to medium in-memory databases and OLAP workloads, such as SAP BW/4 HANA. The Ultra High Memory family is optimized to run large in-memory databases and OLTP workloads, such as SAP S/4 HANA.
Very High Memory instance profiles
The very high memory family of 2nd generation virtual server profiles are built atop the 2nd Generation Intel® Xeon® Scalable processors. These profiles provide a broad set of capabilities and scale from 2 vCPUs (1 physical core) up to 176 vCPUs (88 physical cores). The profiles are targeted towards workloads that need a higher amount of memory per core.
The very high memory 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.
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.
Profile | vCPUs / Cores | Memory (GiB) | Instance Storage | Sockets per Host (NUMA) | Supported Instance Types |
---|---|---|---|---|---|
vx2d-host-176x2464 | 176 / 88 | 2464 | 5280 GB | 4 | vx2d (all) |
Ultra High Memory instance profiles
The ultra high memory family of 2nd generation virtual server profiles are built atop the 2nd Generation Intel® Xeon® Scalable processors. These profiles provide a broad set of capabilities and scale from 2 vCPUs (1 physical core) up to 200 vCPUs (100 physical cores). The profiles are meant for high-end, in-memory database workloads such as SAP HANA.
The ultra high memory 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.
