Data Storage: 10Gb iSCSI Connectivity Wins Acceptance in Data Centers: 10 Reasons Why
Storage connectivity is evolving away from wires and embracing the Internet, according to industry researchers, IT managers and storage vendors. Fibre Channel, powerful high-speed cable connectivity most often used in large data centers for high-transaction workloads, has been on the market for decades. But it's expensive and complicated to use. On the other hand, the Internet Small Computer System Interface (iSCSI)an end-to-end protocol for transporting storage I/O block data over an IP networkhas matured. Thanks to continued development of networking software and increased power in processors, it now is claiming new market share as IT managers and CTOs look to revamp or upgrade their data centers for increased cloud system usage. This eWEEK slide show, put together with information from storage controller maker Emulex, is admittedly a one-sided perspective of this very competitive global market. But it serves as a basic primer on the evolution of this storage technology.
More Storage for Less CAPEX
The constant search for ways to reduce capital expenditures, or "CAPEX" as its known to business managers, is the No. 1 reason why IT decision-makers are looking at iSCSI is to save costs. A conventional Fibre Channel SAN port for a director commonly costs $1,200 per port and FC switches can run $800 a port. Each FC host bus adaptor (HBA) costs about $1,500; then there is the cost of high-end storage arrays. FC hardware isnt cheap.
