Yes, it is possible. 

You can run a MD1000 either as an expansion unit for MD3000(i) (but not
more than 2x per MD3000(i)) or as JBOD. 

The JBOD then can either be used on SAS5 HBA w/o RAID function or
connected to any external Perc to enable you to run RAIDs.

We have an MD3000 with 2 x MD1000 chained off it.

We now want to add another MD1000, can we add more SAS cards to the
server and attach the MD1000 to them ?

Ie can we have independent connections to an MD3000 and an MD1000 ?


Many thanks,
