7050S-64 LAG 40Gb Ports

[clabs]

I inherited a pair of 40Gbe NICS and was looking at setting up a small storage network to experiment with. The Arista 7050S-64 is in my budget. I was wondering if anyone knows if the 4 40Gbe QSFP+ ports can be run in a LAG? I was planning on having the NAS box connect to these 4 ports and all other devices on the 10Gb-BaseT ports.
