- Reduced connectivity costs. Leveraging existing IP infrastructure and commodity NICs will definitely reduce costs as compared to Fibre Channel storage area networds. Fibre Channel HBAs still hover around $1k each, and SAN port costs are about the same. Don't forget nearly $250 per FC cable and you're up to $2,250 per node on the SAN. If your $1,500 blade server is dual connected to the SAN, you just spent 3x what the server was worth on connectivity. Compare that to almost free via iSCSI and you have a bargain.
- Reduced manpower costs. Everybody has an existing network infrastructure. As a result, everybody has a network administrator. Don't expect the network admin to belly up the FC SAN and work wonders overnight. It takes special training and experience to make a iSCSI SAN storage system sing.
