 Comparing the different SAP-certified IaaS offerings 

When you compare the different SAP-certified IaaS offerings available on IBM Cloud, keep in mind that each offering was designed to provide flexibility for various scenarios. Each offering provides different levels of performance criteria, security, and risk-acceptance.

Each of these SAP-certified offerings is available to support numerous different SAP Business or SAP Technical Applications. However they differ in the performance they can achieve:



* Bare Metal very offers high performance. This option has no software-related overheads as it is purely an OS and the SAP software that uses local SSD storage. However, the SAP workload cannot move around as easily.
* Intel Virtual Servers for VPC uses an IBM Cloud managed hypervisor. This option provides lower total cost of ownership when coupling Suspend Discounts and Sustained Usage Discounts, with more flexibility and an abundance of extra features for security and networking. However, the performance and sizing are lower than other options.
* IBM Power Virtual Servers use the enterprise-grade IBM PowerVM Type 1. This option is a complementary offering from IBM Power Systems, with connection through IBM Cloud, that provides significant scalability on robust hardware with significant flexibility and many more features available. But, this option does not allow root-access control of IBM PowerVM underneath where some SAP tools would ordinarily provide integration. Commonly this is paired with existing IBM Power or IBM Z infrastructure in on-premises data centers, to create a Hybrid Cloud model which drives modernization using paired capabilities from either on-premises or Cloud that address the business needs (e.g. security, flexibility, speed etc.) and business strategy
* VMware is a Type 2 hypervisor. This option has a minor reduction in the available performance. But this option also has vastly more flexibility and optimization in running SAP workloads, including:

A very cost effective configuration is cx2-128x256, which allows 128 cores and 2 GB memory per core. This can cover a broad range of MPI workloads.

Scalable MPI jobs can be set up that require multiple virtual machines that are configured at up to 80 Gbps apiece, but that requires multiple NICs and might not be desirable. It is recommended to pick a configuration that provides the best network bandwidth per core with single NIC. bx2-16x64 might be a good starting point for your MPI benchmarking.



 Benchmarking of specific workloads 



 Electronic Design Automation (EDA) 

IBM Systems and IBM Research work in this industry domain and have successfully used IBM Cloud for such workloads. The following graph displays a scale test for up to 30 K cores. To showcase how cloud zones can be used as a single data center, we built a large HPC cluster aggregating the resources across three IBM Cloud locations. The setup also uses IBM Spectrum Scale as a scratch-based, high-performing file system along with IBM Spectrum LSF for HPC cluster configuration. We have used BX2-48x192 for IBM Spectrum LSF worker nodes and MX2d-16x128 for storage nodes under the IBM Spectrum Scale.

 Weather (WRF Model) 

IBM Cloud shows linear performance, performs favorably, and can scale well into thousands of cores. The virtual machine configuration that is used for this benchmark is bx2-16x64. The WRF model is not sensitive to network latency as it packs many variables into each message, resulting in fairly large messages, and not many small messages.

 Deployment Options 

The MAS Cloud Service supports two architectural deployment options, Dedicated Cluster and Shared Cluster, each of which require Capacity Units, Virtual Processor Cores and Gigabyte entitlements. The difference between the two options is how the Cloud Service is deployed and used. For both deployment options, the client will have their own MAS Applications and their own database schemas, but the underlying architecture will be different. The Cloud Service will be configured based on the deployment option purchased.

Clients who purchased MAS-MS (Managed Service) or were quoted prior to December 2022 are Shared Cluster deployment. Clients who were quoted and purchased off that quote after January 2023 are MAS-Dedicated Cluster deployment. If you are not sure which deployment option you have please contact your IBM sales person, CSM or open a support ticket.

Dedicated Cluster Deployment (default)

With the Dedicated Cluster deployment (otherwise known as MAS-Dedicated), Red Hat OpenShift is not shared by multiple Production Instances(s), Non-Production Instance(s) or Clients. Each MAS Client Production Instance and Non-Production Instance will have its own Services and it will not be shared across clients. Clients choosing the Dedicated Cluster deployment will determine when they wish to implement MAS-Dedicated software upgrades. The upgrade may be postponed or deferred by the client. Client will need to communicate to IBM Support if they wish to defer an upgrade. The following exceptions apply:



* Client must always be on a supported version. Client will need to upgrade their current version before it reaches the end of support date.
* Client will always be required to accept critical security patches. IBM alone will determine whether a patch is deemed a critical security patch and the date it will be applied.



Shared Cluster Deployment (optional)

In the Shared Cluster deployment (otherwise known as MAS-MAS), Red Hat OpenShift will be shared across multiple Production Instance(s), Non-Production Instance(s) and Clients. Clients choosing the Shared Cluster deployment will be subject to the software upgrade policy that is set by IBM SRE. IBM will determine and communicate when upgrades will occur, and no deferrals or exceptions will be allowed.

Standard maintenance windows for Production environments are planned on weekends (Saturday / Sunday).

Table 4. Network interface add-ons

 Field Details 

 Bandwidth 250 GB are included with monthly instances that have a public uplink. You can purchase larger allocations at a reduced cost compared to the overage rate. 
 Hardware and software firewalls Firewall services prevent unwanted traffic on your servers, reduce the likelihood of an attack, and allow your server resources to be dedicated for their intended use. 
 Primary IP address A primary IP address is automatically assigned to your instance. 
 Public secondary IP addresses These subnets are owned by you during your virtual server instance ownership. You can cancel the subnet separately, but if you cancel your instance, the subnet is also removed. For more information, see [About subnets and IPs](https://cloud.ibm.com/docs/subnets?topic=subnets-about-subnets-and-ipsabout-subnets-and-ips). 
 IPv6 and public static IPv6 addresses You can select an IPv6 address or public static IPv6 addresses for your instance. 
 VPN management This option is automatically selected for your instance with unlimited SSL VPN users. For more information, see [About VPN](https://cloud.ibm.com/docs/iaas-vpn?topic=iaas-vpn-getting-started). 









 Next steps 

A series of emails is sent to your administrator: acknowledgment of the provisioning order, provisioning order approval and processing, and provisioning complete. The provisioning complete email includes a link to your Device Details page after you log in to IBM Cloud.

After your virtual server is provisioned and available to use, you can configure your virtual servers by using the IBM Cloud console or SoftLayer API.

 Virtual private cloud restrictions 

An IBM Cloud VPC cannot be peered with other VPCs natively. It is possible to connect VPCs by using either Transit Gateway, VPN Gateways, or Floating IPs.



* Both VPN Gateways and Floating IPs can't use an automatic route advertisement between the two VPCs. Static routes must be used in each VPC to enable layer 3 connectivity between the two VPCs. See [Example: Connecting two VPCs by using the VPN](https://cloud.ibm.com/docs/vpc?topic=vpc-vpn-example) for how you can achieve VPC-to-VPC connectivity by using this method.
* With Transit Gateway, it advertises the root subnets of each VPC allowing traffic to be routed without the use of static routes. For more information, see [Getting started with IBM Cloud Transit Gateway](https://cloud.ibm.com/docs/transit-gateway?topic=transit-gateway-getting-started).







 Network restrictions 



* Multi-zone regions - A security group can’t reference another security group in a different zone in the same region.
* VPN - A VPN gateway serves only subnets that are in the zone in which the VPN is created. For more information, see [About VPN](https://cloud.ibm.com/docs/vpc?topic=vpc-using-vpn).
* z/OS - Experimental Deleting a subnet through the user interface might not work as expected when you delete an existing VPC. You can use the command ibmcloud is subnet-delete as the workaround.







 Compute restrictions 



* Every x86-based profile has a network performance value of 2 Gbps per vCPU, with a cap of 80 Gbps.
* Each x86-based network interface has a network performance cap of 16 Gbps.
