Web Tools
Web Tools provides a graphical interface that allows to monitor and manage entire fabrics and
individual switches and ports from a standard workstation. All switches in the fabric are displayed in
the main window of Web Tools, including switches that do not have a Web Tools license. However,
only switches that have a Web Tools license installed can be managed by Web Tools (other switches
must be managed through Telnet or SES).
Web Tools provides the following information and capabilities:
•
Monitoring and managing the entire fabric: status of all switches in the fabric, access to event logs
for entire fabric, zoning functions, access to the Name Server Table, Telnet functions.
•
Monitoring and managing individual switches: summary information about each switch, access to
event logs for individual switches, switch configuration and administration, ability to upgrade
Fabric OS and license key administration, report capability for switch configuration information.
•
Monitoring and managing individual ports: port status, information about connected devices,
performance.
SES (SCSI-3 Enclosure Services)
SES enables an SES host connected to a fabric switch to manage all the switches in the SAN. This is
done remotely, in-band, through a Fibre Channel link.
•
Access to and management of every Brocade SilkWorm switch in the fabric
•
Manage a fabric of Brocade SilkWorm switches in a storage environment that is exclusively SCSI
based
•
Configuration of switches in a fabric (for example, enabling or disabling a port)
•
Performance monitoring (for example, view frame and word counters of a port)
•
Enclosure monitoring (for example, view temperature sensor readings)
•
SES-enabled host can immediately begin managing Brocade SilkWorm switches.
ISL Trunking
The ISL Trunking feature allows up to four Inter-Switch Links (ISLs) to merge logically into a single
link. An ISL is a connection between two switches through an Expansion Port (E_Port). When using
ISL Trunking to aggregate bandwidth of up to four ports, the speed of the ISLs between switches in a
fabric is quadrupled. For example, at 2 Gb/s speeds, trunking delivers ISL throughput of up to 8 Gb/s.
The ISL Trunking feature
•
routes data in the switch network
•
optimizes bandwidth utilization
•
preserves in-order delivery
•
enables load balancing of traffic at the frame-level as opposed to Fibre Channel Shortest Path First
(FSPF), to achieve faster fabric convergence, as well as higher availability in the fabric.
QuickLoop (to create virtual private loops across the switch)
QuickLoop is a migration path from a single private Loop to a fully scalable Fabric for constructing
Storage Area Networks (SAN). QuickLoop enabled switch (or switches) can be used to replace hubs
when a SAN is first deployed. When Nx_Port devices become Fabric capable, the SAN can be
upgraded to mix QuickLoop and Fabric switches and continue to expand towards a full Fabric.
