Dell R710 Embedded ESXi question

Hi Experts,

Basically I am doing some digging to see how it  is installed on the host....so far I have:

/bootbank -> /vmfs/volumes/9dce70ec-7e2dba09-1265-13b8642bf37e

vmkfstools -P /vmfs/volumes/9dce70ec-7e2dba09-1265-13b8642bf37e
vfat-0.04 file system spanning 1 partitions.
File system label (if any):
Mode: private
Capacity 261853184 (63929 file blocks * 4096), 102584320 (25045 blocks) avail
UUID: 9dce70ec-7e2dba09-1265-13b8642bf37e
Partitions spanned (on "disks"):
        mpx.vmhba32:C0:T0:L0:5
Is Native Snapshot Capable: NO

   Is Boot USB Device: true


So this tells me that it is installed on some inetrnal flash storage.....correct?

But when I go into the iDRAC6 all I get is :

 Operating System      VMware ESXi 5.1.0 build-1117900      
Operating System Version      5.1.0 Update 1 Patch 13 (build-1117900)...
 vFlash       - Absent
 Note: SD card not detected. Please insert an SD card of size 256MB or greater.

So how the hell is it installed on this R710? if it is removable is it on a usb stick inside or outside?

Also why does none of the show up int he client when I click on storage/devices? I see all the SAN LUNs and the CDROm but none of this?
