We've got 2 M1000e's, but they're slowly being retired and TBH they're in a 'do-less not do-more' situation (mostly!), so I haven't honestly had much experience past run-of-the-mill blade config, so that particular issue happily hasn't really bitten me :)

But thanks (to both you and Nick) for responding, the FX2s look interesting enough that I might have to see about an eval unit :)
