Hi,
I’m most of the way through rebuilding my home lab and have swapped to Cisco UCS M4 generation gear and am also using UCS manager.
I’m continuing to run VMWare vSAN so tracked down the required UCSB-MRAID12G-HE controllers for my B200M4 blades.
The environment is up and running UCS wise and I’m about to start the VMware config and decided to check the controller and disk queue lengths.
The controller is listed in esxtop as 896 depth, which is correct, by the Cisco SAS SSDs attached to it are only reporting a depth of 64.
I'm using the Cisco ESXi 6.7 U3 custom ISO, and my firmware versions are all the latest release of 4g.
The Cisco SAS SSDs are part numbers:
UCS-SD400G12S4-EP
UCS-SD16TB12S4-EP
All the hardware is on the vSAN HCL and with the exception of the “capacity” drive my setup essentially mirrors the B200M4 AF4 vSAN ready nodes setup.
Does the LSI controller in the “HE” only allow a depth of 64 to drives (instead of the expected 256 depth), or are these drives limited show how?
Any suggestions welcome!
