You can have a datastore created up to 2tb and it depends on your businessneeds,i have not seen any changes with performance when you create a huge datastore or split to smaller ones.
However on VNXe when you create a single 2tb datastore it has to be created on one iSCSI server and intern one SP, in this case you can split into two 1tb datastores and have each of them created on two different iSCSI server and on two different SP's for achieving better performances.
So, splitting the datastores on the same SP might not improve performance which is equivalent to creating a large one and splitting them across SP's will make use of space and spindles on both the SP's.
