Unfortunately I can't tell you whether the host contains an SD slot. Anyway, there's no need to use any 3rd party tools. Just connect the Flash/USB/SD drive to the hosts and run the ESXi installation from the CD-ROM. You should be able to pick the Flash drive as the installation drive during the installation.
Regarding the VDs. It's interesting to see VD2. I'm interested how this works, must be a combination of RAID 10 and JBOD!? Anyway, I wouldn't use this for production, as it doesn't seem to provide on failure protection, nor does VD1 which is a JBOD. Only VD1 seems to be a RAID1 set, with no hot spare however.
