I know the "limitations" of Xsan2

Number of storage pools in a volume : 512

Number of LUNs in a storage pool : 32

Number of LUNs in a volume : 512

Number of files in a volume : 4,294,967,296

LUN size : Limited only by the size of the RAID array

Volume size : Limited only by the number and size of LUNs

File size : Approximately 263 bytes

Volume name length : 70 characters (A–Z, a–z, 0–9, and _ )

File or folder name length : 251 ASCII characters

SAN name length : 255 Unicode characters

But what are they for Xsan3? And then specific for the max file or folder length..?
