Shared Filesystems for SAS Viya on Linux ?

[BigSASFan]

Dear Fellow Viya Admin,

We are moving from SAS9.4 to Viya, one interesting thing is to pick the ideal shared filesystem.

I am curious what kind of shared filesystem your Viya utilizes? 

I appreciate kind reply,

Lei

Hi Lei,

as you know, SAS main requirement, in order to optimise performance, is that your Shared File System must be able to provide a minimum of 100-150 MB/sec/physical core, without disturbances (eg: the file locks NFS often experiences). Aside from this, the question is mostly on the infrastructure side, and what might be already supported/tested by SAS R&D. Hence, you might want to align your infra architects with SAS regarding this question.

For now, SAS has published a ton of information in this subject. To give a couple of very notorious papers:

If your infra is on-premises, you have a lot of possibilities, not only on Shared FS product, also with configurations. You can base your selection on experiences with SAS GRID systems, as the concept with SAS Viya is mainly the same:

If you deploy in the cloud, your options are more limited, because not all Shared FS products have full support, but you still have plenty of options, even not listed or tested: https://www.sas.com/content/dam/SAS/support/en/sas-global-forum-proceedings/2020/4312-2020.pdf

Hi,

If you are on-prem or clouds based the IBM Spectrum Scale file system has been tested by SAS and can provide the performance per core needed to support the application requirements.

We have tested our solution in Azure (Sycomp Storage Fueled by IBM Spectrum Scale) with Margaret's team and they found it to be very performant and scalable.

Let me know if you would like to discuss further.
