Hi Members,

Looking for any references where SAS Viya 4 storage is provisioned from Red Hat OpenShift Data Foundation (ODF).
If anyone has come across such a use case, kindly do share. 

 

TIA!

Hi @JuanS_OCS ,

Nice to hear from you too. Hope all is well!

Thanks for sharing, BTW I have seen these references already. I am looking for some references on a actual implementation done by any customer. Since SAS requires certain storage performance, I wanted to see if any customer was able to achieve this using ODF.

 

The solution offered by HPE includes their storage solution and CSI and doesn't run ODF.

HPE GreenLake for Block Storage built on HPE Alletra Storage MP is an all-NVME, scale-out, disaggregated block storage offering that has the flexibility to scale performance and capacity independently of each other. It uses the HPE Container Storage Interface (CSI) driver to present storage to the OpenShift layer for dynamic volume provisioning by SAS Viya.

Hi @AnandVyas ,

 

@JuanS_OCS has provided you with the most comprehensive documentation you ought to know.

 

We use SAS Viya on OpenShift Bare Metal (on premises) with the following combination :

 

- Micro-service Stateful storage within ODF

- SASWORK/CAS Cache directly accessing Worker Node local storage through HostPath

- Shared Filesystem for SAS Studio through NAS/NFS to be replaced with GPFS.

 

 Performance with ODF may vary, on our platform they use CEPH as backend storage behind ODF and ODF is going to be replaced by PortWorx in the coming months.

No issue found with ODF so far but as you can see, critical storage consumed by SAS jobs , especially WORK, are not relying on ODF.

Thank you @ronan ! Excellent addition.

 

In fact what you mentioned, I'd say it likely applies to most SAS Viya deployments, regardless of the platform behind, since, in the end, it is a general storage performance consideration.
