Sizing
Sizing applies to three key areas - compute, network, and storage.
Compute
Amazon has certified multiple instance families with different sizes to run
SAP workloads. For more details, see Amazon EC2 Instance Types for
SAP
To provision instances based on your requirements, you can use the Right sizing
For a greenfield (new) deployment of SAP workloads, you can use the Quick Sizer tool
For migrations, you can use any of the following data sources to decide the right size of your instance:
-
Source system utilization and workload patterns, such as EarlyWatch alert reports.
-
Source system specification: CPU, memory, storage size + throughput + IOPS, network.
-
Source system SAPS rating.
For more details, see Compute & storage .
Network
Network performance is often not explicitly stated as a requirement in SAP
sizing. Amazon enables you to check the network performance of all Amazon EC2 Instance
Types
Ensure that you have your network components setup to deploy resources
related to your SAP workload. If you haven’t already setup network components
like Amazon VPC, subnets, route tables etc., you can use the, Amazon Quick Start
Modular and Scalable VPC Architecture
You also must set up a secured network connection between the corporate data center and the Amazon VPC along with the appropriate route table configuration, if it isn't already configured.
Storage
Deploying SAP workloads on Amazon required a minimum storage size and layout, based on your choice of OS/DB platform. For further details, refer to the relevant SAP documentation. You need to create Amazon EBS volumes that match these requirements.
You must check that the storage required is enough to provide sufficient I/O
performance. The new gp3
volume is ideal for Oracle workloads that
require smaller volume size. With gp3
, the storage throughput and
IOPS are decoupled from the size and can scale independently.
The io2 volume is well-suited for I/O-intensive database workloads that
require sustained IOPS performance or more than 16,000 IOPS. The io2 Block
Express
is another provisioned IOPS SSD volume for workloads that
require sub-millisecond latency, sustained IOPS performance, and more than
64,000 IOPS or 1,000 MiB/s of throughput.
For more details, see Storage for Oracle.
