This paper describes the move to 4 Gb/s Fibre Channel, the benefits and the
major applications that will benefit from this newest interconnect technology.
4 Gb/s Fibre Channel
Storage System
The IBM®
TotalStorage®
DS4800 controller,
features sixth
generation system
technology and offers
the same extensive
capabilities and
functionality as other
IBM DS4000 series
Fibre Channel
systems. These
capabilities include
broad support for
operating systems and
host types; advanced
replication services
such as Snapshot,
remote volume
mirroring and volume
copying.
Introduction
Since the 2001 introduction of 2 Gigabit per second (Gb/s) Fibre Channel
(FC) technology, engineers have been working on the next generation of
Fibre Channel interconnection – 4 Gb/s. The new technology is now
available, thoroughly tested and offered to enterprise customers.
4 Gb/s Fibre Channel systems are ideally suited for applications that need
to quickly transfer large amounts of data – such as remote replication
across a SAN, database in memory; streaming video on demand; medical
imaging; data mining and data warehousing; and large databases
supporting online transaction processing (OLTP). Additionally, large
increases in online data, such as driven by radio frequency identification
(RFID) applications, will leverage the benefits of 4 Gb/s Fibre Channel
technology.

- Page 2 Why buy 4 Gb/s Fibre Channel technology? The potential benefits of 4 Gb/s Fibre Channel technology include communication faster between servers and storage devices the ability to more rapidly transfer data from storage to server or restore data from online backup media; high reliability due to the number of connections;...
- Page 3 Campus area replication While wide area network (WAN) replication can help provide outstanding protection against regional disasters, campus area replication can be just as beneficial. When replicating across the high-speed SAN, data can be mirrored synchronously, so the remote site has the same data as the local site at all times. The data at the remote site can then be used for a variety of purposes, such as data restoration, mining, analysis, testing and backup.
- Page 4 Database in Memory Customers running this emerging application need to have very large datasets in memory. Loading or refreshing these from disks becomes a time-critical effort. Large Linux™ clusters are an example of this type of computing complex, where loading as much as 12TB of memory from disk storage in less than seven minutes can be the requirement.
- Page 5 Transitioning from 2 Gb/s to 4 Gb/s According to a 2003 IDC report, 2 Gb/s Fibre Channel accounted for only six percent of the market in 2001, but by the end of 2002 2 Gb/s represented 70 percent of the market. IDC also predicted that by December 2003, 1 Gb/s technology would no longer be sold.
- Page 6 Once the decision to upgrade has been made, the transition can take place quickly. Products are already being released based on 4 Gb/s Fibre Channel and as storage products continue to evolve, many will be designed based on 4 Gb/s standards. Storage vendors know that customers rarely replace their entire infrastructure at once.
- Page 7 Conclusion Many industry analysts, customers and manufacturers agree that by the end of 2006, 4 Gb/s Fibre Channel technology will be widely adopted by organizations around the world. Four Gb/s Fibre Channel is backwards compatible, provides customers with state- of-the-art interconnection technology at the same price and cost of ownership as current 2 Gb/s systems.
