What is a Power Systems Virtual Server?
IBM Power Systems Virtual Server is a Power Systems enterprise infrastructure as a service (IaaS) offering. Power Systems Virtual Servers are physically located with low-latency connectivity to the IBM Cloud infrastructure. In the data centers, the Power Systems Virtual Servers are separated from the rest of the IBM Cloud servers with separate networks and direct-attached storage. The internal networks are fenced but offer connectivity options to IBM Cloud infrastructure or on-premises environments. This infrastructure design enables Power Systems Virtual Server to maintain key enterprise software certification and support as the Power Systems Virtual Server architecture is identical to certified on-premises infrastructure. The virtual servers, also known as logical partitions (LPAR), run on IBM Power Systems hardware with the PowerVM hypervisor.
With the Power Systems Virtual Server service, we can create and deploy one or more virtual servers (that are running either the AIX, IBM i, or Linux operating systems). After provisioning the Power Systems Virtual Server, it is your responsibility to make sure that your operating system is secure.
Current AIX, IBM i, and Linux clients can use the Power Systems Virtual Server service for a number of workload scenarios, including disaster recovery, development environments, and partial IT infrastructure moves. Power Systems Virtual Server clients can stay competitive with the scaling of their infrastructure and remain flexible with their workload management and capacity both on- and off-premise. And since the infrastructure layer is identical, system administrators who run on-premises AIX, IBM i, and Linux systems today can use their same tools, workflows, and enhancements in the Power Systems Virtual Server.
Key features
The following are some of the key features for the Power Systems Virtual Server service.
Straightforward billing
The Power Systems Virtual Server service uses a monthly billing rate that includes the licenses for the AIX and IBM i operating systems. The monthly billing rate is pro-rated by the hour based on the resources deployed to the Power Systems Virtual Server instance for the month. When you create the Power Systems Virtual Server instance, you can see the total cost for your configuration based on the options specified. We can identify what configuration options provide you with the best value for your business needs. See Pricing.
The Power Systems Virtual Server service does not provide Linux stock images. You must bring your own Linux image (OVA format) and subscription. Only SLES OVA images are currently supported. Learn more
Infrastructure customization
We can configure and customize the following options when you create a Power Systems Virtual Server:
- Number of virtual server instances
- Number of cores
- Amount of memory
- Data volume size and type
- Network interfaces
Bring your own image
IBM provides you with stock AIX and IBM i images when you create a Power Systems Virtual Server. However, you can always bring your own custom AIX, IBM i or Linux image that you've tested and deployed.
Support for SAP NetWeaver or SAP HANA applications
When you provision a Power Systems Virtual Server instance to support SAP NetWeaver applications, select a version of the IBM-provided AIX or Linux stock operating system image. When you provision a Power Systems Virtual Server instance to support the SAP HANA applications, select a version of the IBM provided SUSE Enterprise Linux server (SLES) stock image. IBM i operating system and custom AIX and Linux images are not supported for SAP workloads. For information about the supported operating system versions, see FAQ.
Hardware specifications
The following IBM Power Systems can host a Power Systems Virtual Server: IBM Power System E880 (9119-MHE) (Dallas and Washington only), IBM Power System S922 (9009-22A), and IBM Power System E980 (9080-M9S) (Data centers other than Dallas and Washington). For more information about these systems and how they're used inside the Power Systems Virtual Server service, see their data sheets and the hardware overview table.
If you'd like to compare your current environment's performance to what's available through the Power Systems Virtual Server service, see the IBM Power Systems performance report. For a more condensed comparison, see IBM Power Systems CPW performance data comparison.

Storage tiers
For each Power Systems Virtual Server instance, you must select a storage tier - Tier 1 or Tier 3. The storage tiers in Power Systems Virtual Server are based on I/O operations per second (IOPS). It means that the performance of your storage volumes is limited to the maximum number of IOPS based on volume size and storage tier. Although, the exact numbers might change over time, the Tier 3 storage is currently set to 3 IOPS/GB, and the Tier 1 storage is currently set to 10 IOPS/GB. For example, a 100 GB Tier 3 storage volume can receive up to 300 IOPs, and a 100 GB Tier 1 storage volume can receive up to 1000 IOPS. After the IOPS limit is reached for the storage volume, the I/O latency increases.
Currently, the IOPS-based storage tiers are available only in TOK04 data center.
Public and private networks
When you create a Power Systems Virtual Server, you can select a private or public network interface.
Public network
- Easy and quick method to connect to a Power Systems Virtual Server instance.
- IBM configures the network environment to enable a secure public network connection from the internet to the Power Systems Virtual Server instance.
- Connectivity is implemented by using an IBM Cloud Virtual Router Appliance (VRA) and a Direct Link Connect on Classic connection.
- Protected by firewall and supports the following secure network protocols:
- SSH
- HTTPS
- Ping
- IBM i 5250 terminal emulation with SSL (port 992)
Private network
- Allows your Power Systems Virtual Server instance to access existing IBM Cloud resources, such as IBM Cloud Bare Metal Servers, Kubernetes containers, and Cloud Object Storage.
- Uses a Direct Link Connect on Classic connection to connect to your IBM Cloud account network and resources.
Required for communication between different Power Systems Virtual Server instances.
