Hi Assuming you are talking about GPFS QoS and not any fabric QoS. It would work with any supported fabric, ESS or not. It is a filesystem feature well above all the fabrics and HW. Limits IOPS per class
https://www.ibm.com/docs/en/storage-scale/5.1.8?topic=reference-mmchqos-command I recommend (depending on number of nodes and seconds) fine-stats so then you can visualize which PID on which client node is doing what. I believe I did something of that on SSUG London 18 or 19 -- Ystävällisin terveisin/Regards/Saludos/Salutations/Salutacions Luis Bolinches Executive IT Specialist IBM Storage Scale Server (formerly ESS) developer Phone: +358503112585 Ab IBM Finland Oy Toinen linja 7 00530 Helsinki Uusimaa - Finland Visitors entrance: Siltasaarenkatu 22 "If you always give you will always have" -- Anonymous https://www.credly.com/users/luis-bolinches/badges From: gpfsug-discuss <[email protected]> On Behalf Of Thomas Bernecker Sent: Thursday, 7 September 2023 11.36 To: [email protected] Subject: [EXTERNAL] [gpfsug-discuss] Spectrum Scale, InfiniBand and QoS Dear all, we recently found this presentation from 2021: https: //www. spectrumscaleug. org/wp-content/uploads/2021/05/SSSD21DE-06-Improving-Spectrum-Scale-performance-using-RDMA. pdf On page 10 it explains by setting the RDMA device in a specific ZjQcmQRYFpfptBannerStart This Message Is From an External Sender This message came from outside your organization.

Has anyone a working environment using QoS with InfiniBand outside of the ESS domain? If so, would you share your experience? Sorry for asking a rather broad question, but it seems that this is not well-known stuff … -- Best regards / Mit freundlichem Gruß Thomas Bernecker ------------------------------------------------------------------------------------------------------------------ Manager System Integration and Support, HPCE Division Mobile: +49 (1522) 2851523, Fax: +49 (211) 5369-199, Home Office: +49 (38821) 65091 NEC Deutschland GmbH, Fritz-Vomfelde-Straße 14-16, 40547 Düsseldorf, Germany Geschäftsführer: Christopher Richard Jackson – Handelsregister Düsseldorf HRB 57941 ------------------------------------------------------------------------------------------------------------------- Unless otherwise stated above: Oy IBM Finland Ab PL 265, 00101 Helsinki, Finland Business ID, Y-tunnus: 0195876-3 Registered in Finland
