Right now I am using local storage on the ESXi server.  For backups I am manually stopping the VMs and copying the files to a windows server share.  This is not optimal or fun. If I use a Thecus N8800 could I improve my ESXi backup process?  I understand the idea of "storage" but have never implemented iSCSI.  Are you using rsync to backup your ESX VMs?  If so, can it be done while the VMs are running?

I've only tried the N8800 with one ESX host,  but haven't run any production
VM's on it yet, as I'm still testing ( a RAID5 expansion is currently
at 35 hours to complete )   After I move my production VM's I'll post again.

For ESX backup check out a really neat product from PHDvirtual called
esXpress.   It does de-duplicated backup of the VM's while they are
running to a
NFS or SMB share.    With de-dup you only need 10% of your production
drive space
to keep 6 months of daily/weekly/monthly backups.

esXpress spins up several "Virtual backup agents" ( VBA's) to do the
de-duplication and
they store to a companion VM appliance that stores the blocks.

Restores are a matter of running a script that has access to the
de-duplicated file
share.   No software needed for the full restore of the VM.   You can
also restore
individual files without restoring the entire VM.

The price is $1000/host with unlimited sockets, and unlimited VM's, 
limited to
4 VBA's

This does not require Vsphere Vcenter server, however it does require ESX
not ESXi.    It's fairly easy to switch to ESX,  but patching ESX
without Vcenter is
a pain.   Vsphere Essentials was recently on sale for $500 for 3 hosts,

(Disclosure:   I'm a business partner with them,  and do some VMware
for their clients. )
