LVM stripping for SAP on RHEL 8.1

[dnyandev]

Hello,

We are planning to implement the SAP HANA on GCP. I wanted to know if anybody has used LVM stripping to improve the HANA database performance.

I have gone through the following blogs about how it helps to solve IO performance issue.

https://blogs.sap.com/2017/12/18/how-to-free-hana-system-on-public-cloud-from-io-performance-issue/

has anybody done this on GCP and what are the best practices around volume stripping.

Thanks,

Dnyandev Kondekar

Hi Dnyandev,

I would suggest consulting the SAP HANA planning guide and the section on Persistent disk storage.
You can increase storage performance by adding more PD storage or changing storage type.
Specifically I would check out the section and links:

For more information about the different types of Compute Engine persistent disks, their performance characteristics, and how to work with them, see the Compute Engine documentation:

• Storage options
• Block storage performance
• Other factors that affect performance

I hope this helps,
Mike

Hi Dnyandev,

You may also find this terraform module useful, if you are planning to deploy HANA on GCP.  Are you planning on following SAP Adaptive Design Principles?

You probably want to also think about your automation strategy.  Are you thinking of something like Terraform/Ansible for deployment and also use of SAP LaMa for operations etc.?

To get the full benefit of running in the cloud, these are very important factors to consider.
