The XDAS FX-series modular host design based on your needs and budget, select from 8Gb/s or 16Gb/s Fibre Channel, 1Gb/s or 10Gb/s iSCSI (either SFP+ or RJ-45), or 12G and 6Gb/s SAS host interfaces. The wide choices allows for great flexibility in this product line. A company on a budget can start off with cheaper gigabit technology and later when they are able to afford faster technology they can swap modules for Fibre or 10G iSCSI. Host interface modules can be easily swapped and upgraded, making the new XDAS FX more future-proof than any of our prior DAS products.
