RHEL to FreeBSD file server

[Bob Friesenhahn]

I am not able to attest to the type of configuration you are building. 
It all sounds good to me and it would surely work fine with Solaris, 
and so likely with FreeBSD as well.  The only concern might be that 64 
GB of memory is not so much according to today's hardware standards. 
New hardware is easily able to fit 128 GB, 256 GB, or even 512 GB.

If the working set from all those clients is bigger than will fit in 
64 GB of RAM, then your disks will be working much harder than they 
should be.  With zfs, disks don't do any reading (reads will stall) 
while zfs is writing a transaction group.  A proper server should be 
doing mostly writing because key data is already in cache.

With so many clients, make sure that your intent log FLASH devices are 
mirrored and be prepared to replace them periodically.
