Yes.  See Chap 7.3 in:

http://dlc-cdn.sun.com/pdf/820-3681/820-3681.pdf

Not too well worded and no specifics:

"There is one OSS with two Infiniband HCAs. Lustre clients have only
one Infiniband
using native Lustre drivers of o2ibind. Load balancing is done on both
HCAs on the
OSS with the help of LNET."
