As mentioned in another email, the M10i can use the RE-850 which has
1.5 GByte on the RE.

As for the GigE cards: Note that the 4 port GigE PIC for M10i/M7i
(PE-4GE-TYPE1-SFP-IQ2) has 1 GigE (full duplex) backplane capacity,
thus you will *not* be able to run all 4 ports line rate at the same
time. I haven't checked whether the same restriction also applies to
the corresponding M20 card.
