|1.WHAT ARE THE BENEFITS OF FIBRE CHANNEL SANS?
Fibre Channel SANs are the de facto standard for storage networking in the
corporate data center because they provide exceptional reliability,
scalability, consolidation, and performance. Fibre Channel SANs provide
significant advantages over direct-attached storage through improved
storage utilization, higher data availability, reduced management costs,
and highly scalable capacity and performance.
2.WHAT ENVIRONMENT IS MOST SUITABLE FOR FIBRE CHANNEL SANS?
Typically, Fibre Channel SANs are most suitable for large data centers
running business-critical data, as well as applications that require high-
bandwidth performance such as medical imaging, streaming media, and large
databases. Fibre Channel SAN solutions can easily scale to meet the most
demanding performance and availability requirements.
3.WHAT CUSTOMER PROBLEMS DO FIBRE CHANNEL SANS SOLVE?
The increased performance of Fibre Channel enables a highly effective
backup and recovery approach, including LAN-free and server-free backup
models. The result is a faster, more scalable, and more reliable backup
and recovery solution. By providing flexible connectivity options and
resource sharing, Fibre Channel SANs also greatly reduce the number of
physical devices and disparate systems that must be purchased and managed,
which can dramatically lower capital expenditures. Heterogeneous SAN
management provides a single point of control for all devices on the SAN,
lowering costs and freeing personnel to do other tasks.
4.HOW LONG HAS FIBRE CHANNEL BEEN AROUND?
Development started in 1988, ANSI standard approval occurred in 1994, and
large deployments began in 1998. Fibre Channel is a mature, safe, and
widely deployed solution for high-speed (1Gb, 2Gb, 4Gb) communications and
is the foundation for the majority of SAN installations throughout the
5.WHAT IS THE FUTURE OF FIBRE CHANNEL SANS?
Fibre Channel is a well-established, widely deployed technology with a
proven track record and a very large installed base, particularly in
highperformance, business-critical data center environments. Fibre Channel
SANs continue to grow and will be enhanced for a long time to come.The
reduced costs of Fibre Channel components, the availability of SAN kits,
and the next generation of Fibre Channel (4Gb) are helping to fuel that
growth. In addition, the Fibre Channel roadmap includes plans to double
performance every three years
6.WHAT ARE THE BENEFITS OF 4GB FIBRE CHANNEL?
Benefits include twice the performance with little or no price increase,
investment protection with backward compatibility to 2Gb, higher
reliability due to fewer SAN components (switch and HBA ports) required,
and the ability to replicate, back up, and restore data more quickly. 4Gb
Fibre Channel systems are ideally suited for applications that need to
quickly transfer large amounts of data such as remote replication across a
SAN, streaming video on demand, modeling and rendering, and large
databases. 4Gb technology is shipping today.
7.HOW IS FIBRE CHANNEL DIFFERENT FROM ISCSI?
Fibre Channel and iSCSI each have a distinct place in the IT
infrastructure as SAN alternatives to DAS. Fibre Channel generally
provides high performance and high availability for business-critical
applications, usually in the corporate data center. In contrast, iSCSI is
generally used to provide SANs for business applications in smaller
regional or departmental data centers.
8.WHEN SHOULD I DEPLOY FIBRE CHANNEL INSTEAD OF ISCSI?
For environments consisting of high-end servers that require high
bandwidth or data center environments with business-critical data, Fibre
Channel is a better fit than iSCSI. For environments consisting of many
midrange or low-end servers, an IP SAN solution often delivers the most
