M4352pa and M4328pa memory / buffer size?

[joelp1212]

What is the memory buffer size on the M4352 and M4328 switches?  i.e. if too many packets arrive  - example - it should be a holding buffer queue i.e. 10MB 20MB?

Data Sheets are your friends: M4300 series Data Sheet 

Increased packet buffering with up to 96Mb (96p 10G models), 72 Mb (48p 10G models), 32 Mb (24p 10G models) and 16 Mb (all other models)

Thank you.    Is the 16MB Buffer space for M4352 shared among all 52 ports or is it per port?  also how do we know if we have reached or exceed the memory buffer space, is there a log or a statistic we can look-up to guide us?
