I want to benchmark the ability of a single lustre client to save in its lustre-mounted filesystem.
I am an application developer and not a storage maintainer, so i am not worried about storage write bandwidth saturation by several clients, I am worried about how much a single application server/lustre client can write at once so i can compare it to my application performance.
I found this page with several benchmarks , but all seem to be interested in configuring several clients at once instead of using just one client. Is any of these more interesting for what i am looking?
Alternatively, i have a naive script which uses dd to benchmark filesystems in different block sizes and counts. Can I trust the results that I obtained by running this dd script in my lustre client? If not, why? I know i am limited by my network bandwidth, but i am interested in understanding how it limits my performance too.
