However, system performance limitations may be introduced as a result of inefficient system configuration, e. Make sure the Ethernet cable connectors are securely plugged in at both ends. Gaps can occur because an initiator is recovering from a failure or problem. The present invention is configured to address this deficiency in conventional analysis techniques and packages via the sample management process of the invention, which will be further discussed herein. Enter the user name and password you normally use to log on to the Xgig chassis. When the software is sequentially analyzing a trace to determine performance statistics behaviors on timeline, the software must determine various initial values and terminating values for the analysis duration.

The following definitions are applicable to embodiments of the invention: For example, there are stealth switches, public loops, and public loops where there is no switch involved. A solid green light means that the Xgig operating system is up and running and has obtained a valid IP address.
This allows the user to arbitrarily select a timeframe for analysis and maintain exact statistical and expert measurements for the events within the new analysis window. The system architecture illustrates that the SANMetrics package is capable of passing commands between itself and a peer application and sending commands to the SANMetrics IO layer The FC loop state machine embedded into the software of the invention generally trsce an algorithm to determine the status of devices at a predetermined interval in the trade data.
Rather, the data captured by analyzers virwer presented to the user a human being for inspection and determination of whatever faults, errors, or other unwanted conditions exist in the network. Every OPN between a pair of ports starts a new credit arrangement between the ports in the Alternate credit Model.
The communication activity is captured and recorded in a dedicated trace buffer associated with the protocol analyzer, and then analyzed or presented to the user for the purpose of diagnosing, testing or maintaining the communication interface in a trace viewer format. For more information about sequences, refer to sequences. Additionally, if the SCSI operations consist of a mixture of Random reads, the ECT will generally increase due to the additional seek time introduced between operations.

This can be the same PC that will be used to connect with the Xgig chassis through the Ethernet port. These brute force analysis type techniques are generally accomplished by tracf or more preprocessing routines configured to determine where the switches are and what type they are. Without pending exchanges, devices sit idle, waiting for new commands from the initiator.
If multiplexing traffic will be captured this must be switched to "Analog Pass-through Multiplexing " option. For this peripheral qualifier the peripheral device type shall be set to 1Fh to provide compatibility with previous versions of SCSI. Connect the Xgig chassis to the network and verify that the chassis can be accessed from another node on the network. The dongle contains licenses to enable functions for port-pairs in the chassis.
It may be necessary to configure instrument usage on a special sub-net to circumvent this problem.
Therefore, the software is capable of determining errors in the framing, i. Modular blade technology allows quick reconfiguration of chassis.
By the same token, Trace View can request SANMetrics to open a trace and go to the time duration of interest using a similar operation. Some FC devices send only one sequence within a tenancy, thus requiring more tenancies to complete exchanges.

When an application has gathered data to transmit writes or requests data from the targets readsit will generally issue the requests in a burst, driving the pending exchanges values upwards. You will notice Memory Module s on both sides of the blade. With the bracket ears securely attached, mount the Xgig chassis in your equipment rack.
For example, the requesting software on the host computer may no longer be issuing requests, thus the system is returning to an vieqer state.
Refer to the Xgig Blade Hardware Guide for complete information on all available blades. Note that the number of memory modules on one side giewer the blade depends on the type of blade. Although the state machine may be configured to determine status of devices for several protocols, the discussion of the present software package will generally be directed toward an FC state machine.
If there is a constant amount of work to complete between the initiator and the target, the values for completed exchanges should remain constant. The software package of the invention is configured to determine when these types of situations and configurations are at issue and present the information to the user in an easily readable format, which was not possible with conventional analysis techniques.
In this situation, the software determines a workable scale that makes sense across the time frame of the sampled trace. This prevents multiple initiators from creating data over-run or xgiig conditions.

For example, the software may save this information in the trace file or other associated data file so that subsequent analysis runs will have access to the information and will not require duplicate preprocessing or input steps. If this sgig of communication is all that the software observes during the trace, then the software has no way to determine where the switch is, because there is nothing to clue the software in, i.
