One complication is the multiplication of paths 256 is the limit. And whatever delay that occurs in each switch.
(zSeries)16Ficon(McData)16Ficon(DS8000) is 16*16=256 paths. (zSeries)4Ficon(Mcdata)8Ficon(McData)8Ficon(DS8000) is 4 * 8 * 8 = 256 paths. (zSeries)4Ficon(Mcdata)4Ficon(McData)4Ficon(McData)4Ficon(DS8000) is 4 * 4 * 4 * 4 = 256 paths. (zSeries)2Ficon(Mcdata)2Ficon(McData)2Ficon(McData)2Ficon(Mcdata)2Ficon(McData)2Ficon(McData)2Ficon(McData)2Ficon(DS8000) is 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2= 256 paths.
