Compatible expander card to HP SmartArray p222

i've got an HP ProlIant Microserver Gen8.

After some time internal storage of it became full. So i've got plans to install additional JBOD to it (DAS) with use of HP SmartArray p222 that compatible with Microserver Gen8. To minimize wiring i want to use an expander card in JBOD, but i can't find what product compatible with p222.

So, could somebody clarfy is 468406-B21 suitable for this (http://www.amazon.com/gp/product/B0025ZQ16K?ie=UTF8&tag=servecom-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=B0025ZQ16K)?

Or maybe there is another compatible card?
