Hi, It lists both the R720 and R710 under compatible systems and both link to the same page, so the custom version is the same for both servers. The version listed in the reference guide for A02 is megaraid_sas - 06.803.73.00 Page 5 ftp://ftp.dell.com/Manuals/all-products/esuprt_software/esuprt_virt_solutions/vmware-esxi-5_Reference%20Guide6_en-us.pdf   That is the same version it shows for your install on the R710 so that looks correct.
I'm upgrading one R710 and two R720 from ESXi v5.5 (Dell image) to ESXi v5.5 U2 using the Dell image here: www.dell.com/.../DriversDetails The documentation "Upgrade Guide to ESXi 5.5 Using Dell Customized Image" here: www.dell.com/.../manuals states that a specific version of the megaraid_sas driver needs to be installed.   Is the megaraid_sas version that installs with the v5.5 U2 Dell image not the correct version? I just ran the upgrade on one R710 and this is the megaraid_sas version installed: ~ # vmkload_mod -s megaraid_sas | grep Version Version: Version 06.803.73.00, Build: 1331820, Interface: 9.2 Built on: Aug 22 2014Thanks.
R710/R720 - Dell Customized Image of VMware ESXi 5.5 Update 2 - megaraid_sas 
version specific?
