Dell H710P is equivalent to LSI MegaRAID SAS 9266-8i

Dell H710P RAID card is equivalent to LSI MegaRAID SAS 9266-8i so if you want MegaCLI tool to manage the card then you can go to LSI webpage:

http://www.lsi.com/support/Pages/download-results.aspx?component=Storage+Component&productfamily=RAID+Controllers&productcode=P00584&assettype=0&productname=MegaRAID+SAS+9266-8i

"Management Software and Tools" tag and download the MegaCLI for Linux. I am using CentOS 6.x. Inside of the zip file there is a RPM. It works!
To show all cards in your box:

/opt/MegaRAID/MegaCli/MegaCli64 AdpAllInfo -aALL

PS: Check check!

$ /opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -LALL -aALL | grep State

State               : Optimal

Good Luck!
