    VSAN hardware compatibility for Cisco UCS-C240-M4

    AlanRaczek Novice

      Hi-

      Been banging my head against the wall trying to find out that this server supports VSAN 6.7U3. I am looking to upgrade

      the servers from vSphere 6.5 to 6.7U3. I have looked at the VMware compatibility tool (where it has ReadyNodes and

      the general compatibility guide but can't figure it out . I will be upgrading the BIOS and firmware of the servers to

      CIMC 4.1.1.

          Hello Alan,

           

          Welcome to Communities.

           

          There are various configurations of 'UCS C240 M4' on the ReadyNode HCL - please have a look and indicate which one has the same hardware specs as yours (specifically controller, Cache-tier and Capacity-tier devices):

          vmware.com/resources/compatibility/search.php?deviceCategory=vsan&details=1&vsan_type=vsanreadynode&keyword=UCS%20C240%20M4&page=1&display_interval=10&sortColumn=Partner&sortOrder=Asc

           

          But, yes I can see that there are variants stating supported for 6.7 U1/U2 but none for 6.7 U3 (whereas M5 versions are listed for 6.7 U3 and 7.0) - whether this implies Cisco will no longer support them as 'ReadyNodes' on 6.7 U3 or later is a question best asked of Cisco (and/or the party you purchased these servers from).

          That being said, all of the listed components - controller, Cache-tier and Capacity-tier devices - I can see from the models I checked (including the drives that have reached 'End of Sale') are on the HCL for 6.7 U3 and most 7.0. So from a VMware-supported perspective it is fine, but to get into the nuances of whether it is still considered a 'ReadyNode' or not (and thus things like SAS-Expander support) is beyond my station.

            TB-

            Thank you for the response. Being as I just came into maintaining these machines 3 months ago I am not sure of hardware specifics. I am trying to come up with some powercli/powershell that

            will give me that info. AFAIK these are Cisco UCSC-C240-M4SX . I will take a loser look at the readynodes but that page sort of confuses me. Never worked with that guide before.

              Hello Alan,

               

              Getting the controller, Cache-tier and Capacity-tier disk model and part-numbers is generally most accurate from the Cisco UCS Manager.

              However you can generally (as it depends) get this information from:

              # esxcli storage core device list

              # esxcfg-scsidevs -a

              # vmkchdev -l |grep vmhbaX

              Then search for the ID numbers and/or model/part numbers on the HCL directly or here:

              https://hcl.captain-vsan.com/

               

              The current (unsure about past) ReadyNode listings are also available in frequently updated pdf format:

              https://www.vmware.com/resources/compatibility/pdf/vi_vsan_rn_guide.pdf

                Thank you that was helpful. I found most of the hardware and by and large it looks like our hardware supports vSphere 6.7U3. I am just curious about the chaching tier

                and what I am looking for. See this output:

                esx_scsi_devices.JPG

                 

                But as a whole I think I am good. It's hard to get hw info as these machines are not managed by UCS.

                  Hi Alan,

                   

                  As per below vSAN HCL,Cisco 12G SAS Modular Raid Controller (UCSC-MRAID12G) is supported till ESXi 7.0/vSAN7.0,however you looked into  Footnotes for vSAN 6.7 U3 stating  that

                  “Firmware 4.620.00-7322 is packaged within container 24.12.1-0433.Please use one of the following UCS releases for Storage controller firmware & Driver - UCS C-series Standalone releases – 4.0(2d) , UCSM-Managed C series releases – 4.0(2d)”

                   

                     https://www.vmware.com/resources/compatibility/detail.php?deviceCategory=vsanio&productid=38642https://www.vmware.com/resources/compatibility/detail.php?deviceCategory=vsanio&productid=38642

                   

                  But as per Cisco compatibility Matrix, 6.7 U3 does not support current UCSC-MRAID12G controller for firmware version 4.0(2d) for C-series but Vmware Matrix says that use 4.0(2d) for ESXi6.7 U3/vSAN6.7 U3.

                   

                  So have you managed/installed ESXi 6.7 U3 /vSAN 6.7 U3? Is it working fine ? since i m also planning to upgrade ESXi/vSAN to 6.7 U3 for C240-M4SX  server with UCSC-MRAID12G controller,but we are not using vSAN ready Node

                   

                  Regards
