The MDS 9513 and 9509 are designed for what is known as a 'collapsed core'. You can place the high density port line cards like the 32 and 48 port line cards for server attachment, and also install the line rate line cards like the 12 and 16 port line cards for Storage and Tape system attachment. This way you don't need ports dedicated for ISLs reducing cost since each ISL link is 2 dedicated ports (GBICs) and 1 cable.
There is another concept called locality where you design the SAN such that servers and the storage/tape devices they access are on the same switch. The intent here would be to limit traffic using the ISLs to only what you need to.
I would recommend creating a port channel between the 9509 and 9513, using ports from different line cards if possible on each MDS. This way you are protected against a single line card failing and causing a segmented fabric.
