mytime34 Posted November 18, 2021 Share Posted November 18, 2021 To All, I am running 4ea 7.68tb Enterprise SAS 12gb SSD drives and when I run Disk speed, I get the following message. Bandwidth was capped on the folloiwng drives: Cache (sdm), Cache 2 (sdn), test (sdo), test2 (sdp) 2 of these drives are hitting 700mbps, but the other 2 are only hitting 350mbps. Is there a way to uncap the bandwidth? These drives are capable of 900-1100mbps each, and has been tested on a windows machine. Any thought or fixes would be great. Thanks Quote Link to comment

ChatNoir Posted November 18, 2021 Share Posted November 18, 2021 I am not great at deciphering the logs, but that does not seem OK.

In doubt post a screenshot of the results. Quote Link to comment
mytime34 Posted November 18, 2021 Author Share Posted November 18, 2021 I have tried running the tests individually and simultaneous with the same results. Bandwidth is always capped on these 2 drives. My 2 other sas ssd drives do not cap out, they run without issue. Quote Link to comment
JorgeB Posted November 18, 2021 Share Posted November 18, 2021 That then suggests a device issue, they are different brands. Quote Link to comment
