Fibre Channel (FC) SAN
FC vs. iSCSI: Five tips in five minutes
By Andrew Burton
FC is designed to transmit data between computer devices at data rates of up to 4 gigabits per second (Gbps) (and 10 Gbps in the near future). It is designed to connect computer servers to shared storage devices and for interconnecting storage controllers and drives. It's a high-performance, high-cost technology.
iSCSI (or Internet Small Computer System Interface) is an IP-based storage networking standard that has been touted for the wide range of choices it offers in both performance and price. Some analysts say iSCSI is reliable enough for important data and is frequently used for Microsoft Exchange storage. And, because iSCSI uses TCP/IP and SCSI, which have existed for decades and are well understood in the storage world, it's an appealing option for many in the industry.
But, how do you figure out which is right for your environment? Check out the expert technical advice below, and get started learning about how these technologies compare, so you can make the right decision for your environment.
Think that FC is faster than iSCSI? Vice versa? Storage expert Tony Asaro explains why the real answer may surprise you.
Storage expert Christopher Poelker offers insight on setting up clustered storage with iSCSI and how it differs from clustering with FC.
Storage expert Greg Schulz offers advice on how to compare FC and SCSI technology.
Tony Asaro explains why iSCSI is rapidly growing and is a viable alternative to a FC SAN, and the reason that iSCSI performance is an often misunderstood issue.
Storage expert Brett Cooper considers whether performance is the key criteria for deploying a specific storage protocol.
