MSA 2040 SAS connectivity WORKS 6 GB\s no 12 GB\s

Hi, I have a HP MSA 2040 with a SAS connection on HP DL380 G9 servers running Windows Server 2016 Datacenter and the connectivity between the Windows server and the MSA 2040 is only 6 GB \ s while it should be 12 GB \ s. The two controllers on the MSA 2040 are 12 GB \ s and the 8644 12 GB \ s. On the servers I have HP h241 HBA 12 GB \ s cards. But it only works for 6 GB \ s.

Hi BoSsNeX,

I suspect fault with the SAS cable.  Kindly check the SAS cable spare part number used to connect between the H241 controller and the MSA2040 SAS controller.  

As per quickspecs we should be using following 12G SAS cables for 12G SAS initator. 

QuickSpecs : https://h20195.www2.hpe.com/v2/GetPDF.aspx/c04123144   

HP External 1.0m (3ft) Mini-SAS HD 4x to Mini-SAS HD 4x Cable 716195-B21
HP External 2.0m (6ft) Mini-SAS HD 4x to Mini-SAS HD 4x Cable 716197-B21
HP External 4.0m (13ft) Mini-SAS HD 4x to Mini-SAS HD 4x Cable 716199-B21 

In case issue persist with the above P/N cables, capture AHS report and Store logs from MSA and open ticket with HPE Support.

Hope this helps.
