The following Ultra High Memory profiles are available for x86-64 processors:

GPU

The GPU profile family includes -v100, -a100, -l4, and -l40S and -h100 profiles. The GPU profile family includes profiles with and without instance storage.

• GPU -v100 profiles include 1 or 2 NVIDIA V100 PCIe 16 GB GPUs. All OS images are supported on these GPU profiles.
• Select availability GPU -a100 profiles includes 8 NVIDIA A100 NVlink 80 GB GPUs. The a100 offering is available to select customers. This GPU profile supports only Linux OS images Ubuntu or RHEL.
• GPU -l4 profiles include NVIDIA L4 24 GB GPUs.
• GPU -l40S profiles include NVIDIA L40S 48 GB GPUs.
• Select availability GPU -h100 profiles include NVIDIA H100 80 GB GPUs. The system is an HGX design. The H100 offering is available in the following regions and zones: London (eu-gb-2), Sydney (au-syd-2), Toronto (ca-tor-3), Madrid (eu-es-3), Washington DC (us-east-3), Tokyo (jp-tok-3), Sao Paulo (br-sao-1), Dallas (us-south-1), and Frankfurt (eu-de-2).

See Download drivers to review the most current versions that are supported. NVIDIA GPU drivers must be installed separately.

Storage Optimized

Storage Optimized profiles are hosted exclusively on Intel® Xeon® Platinum Cascade Lake servers. This profile family offers our highest vCPU to instance storage ratio with 300 GB of storage for every 1 vCPU and is optimized for running data lake and other workloads that require more intensive data capabilities. All storage optimized profiles are provisioned with temporary SSD-backed instance storage at no additional charge. For more information, see Lifecycle of instance storage.

Storage Optimized profiles use the Storage optimized (ox2) instance storage quota, for instance, storage quota tracking. Unlike other profiles, which use the Instance storage quota. For more information, see Quotas.

Storage Optimized profiles are available in the US South (Dallas), US East (Washington DC), United Kingdom (London), Germany (Frankfurt), EU Spain (Madrid), Japan (Tokyo), and Japan (Osaka) regions.

The following Storage Optimized profiles are available for x86-64 processors:

Confidential computing profiles

Select availability

The following profiles support Confidential computing with Intel Software Guard Extensions (SGX), Confidential computing with Intel Trusted Domain Extension (TDX), and secure boot.

For more information about confidential computing, see Confidential computing for x86 Virtual Servers for VPC.

Bandwidth allocation

Instance bandwidth is allocated between volume bandwidth and networking bandwidth. The bandwidth capacity (Bandwidth Cap) is determined by the virtual server profile that you select during instance provisioning. For example, a bx2-2x8 balanced server profile allows a bandwidth cap of 4 Gbps.

Block Storage volume notes for profiles

When you create secondary data volumes, you select a volume profile that best meets your requirements. Volume profiles are available as three predefined tiers or as a custom profile. These volume profiles relate to virtual server instance profiles:

• A 3 IOPS general-purpose tier profile provides IOPS/GB performance that is suitable for a virtual server instance Balanced profile.
• A 5-IOPS tier profile provides IOPS/GB performance that is suitable for a virtual server instance Compute profile.
• A 10-IOPS tier profile provides IOPS/GB performance that is suitable for a virtual server instance Memory profile.

Viewing profile configurations

You can view available profile configurations by using the IBM Cloud console or the CLI. In the IBM Cloud console, you can select from popular profile configurations that support the most common use cases.

Next generation instance profiles

The 3rd generation of IBM Cloud Virtual Servers for VPC are available to provision in all regions. This new generation features virtual server profile families that are hosted exclusively on Intel 4th Generation Xeon Scalable processors to provide the most powerful and performant general-purpose profiles available. These 3rd generation profiles provide the following enhancements:

• Improved performance with DDR 5 memory DIMMs, PCI Gen 5 interconnects, and more memory per vCPU than prior generation profiles.
• A wide variety of profiles sizes with core to memory ratios optimized to maximize performance and economics for intensive workloads.
• Enhanced integrated accelerators that feature AMX-512, AVX, and enhanced crypto acceleration.
• Instances are started by default with Open Virtual Machine Format (OVMF), and run in Unified Extensible Firmware Interface (UEFI) mode for enhanced security.
• Local instance storage is included with all profiles for ease of access to temporary storage and swap space. For more information about the temporary nature of instance storage, see Lifecycle of instance storage.
• A 3rd generation profile can be resized to a 2nd generation profile. A 2nd generation profile can be resized to a 3rd generation profile. For more information, see Resizing between Gen 2 and Gen 3 profiles.

Intel Hyper-Threading Technology

All Intel® x86-64 servers have Hyper-Threading enabled by default. Intel® Hyper-Threading Technology is a term that describes simultaneous multithreading (SMT). Hyper-Threading Technology splits each physical core into two virtual processors. Hyper-Threading Technology is like taking a wide road with a single lane and making it into two relatively narrower lanes. The two-lane highway provides better service over the single-lane road if traffic is moving slow and fast. Hyper-Threading Technology provides better application performance for File I/O, Network I/O, and other slower operations mixed with CPU-intensive operations. The performance advantage of Hyper-Threading Technology typically ranges in the range 0 - 30% over a single-thread mode. Some applications might also see a drop in performance.
