 From the fstab(5) man page:
"The fourth field, (fs_mntops), describes the mount options associated 
with the file system.  It is formatted as a comma separated list of 
options.  It contains at least the type of mount (see fs_type below) 
plus any additional options appropriate to the file system type.  See 
the options flag (-o) in the mount(8) page and the file system specific 
page, such as mount_nfs(8), for additional options that may be specified."

What trouble did you have with fstab?  You can specify as many options 
as you want as long as you separate them with commas (I think putting a 
'=' between an option and its value is also necessary, although I don't 
know for sure).  For you it should look like this (assuming you want 
read/write):

dell:/nfs  /dellbak  nfs  rw,-s,-x=2,-T  0  0
