Hi Team,

As doc said,in a production environment, each node is likely to have at least 12 physical disks and do not use RAID or Logical Volume Management on any disks or partitions for use by MapR.

 Can you recommend some detailed info about the server which make MapR performance better?
   Such as Dell Power Edge 2950 or HP ProLiant DL388p or any other server.

 How to cancel Logical Volume Management on server?
 Because when i install CentOS on server, the LVM would be add to the system partion by default.

 How LVM impact on MapR?
