1 Overview

This chapter describes the event levels and event signal flows.

Event LevelAn event level indicates the severity of the event to the system services. The event level isdisplayed on the DeviceManager interface and can be classified into the following levels:

l CriticalThis level indicates that a fault has caused service interruption or device failure. Recoverymeasures should be taken immediately.

l MajorThis level indicates that a fault has certain impact on the device or system performance.Measures should be taken immediately to prevent more serious faults. All hardware faultsare of the level.

l WarningThis level indicates that a fault has no impact on the device. The system detects a potentialor an imminent fault that is about to affect the services.

Event Signal FlowIf the storage system is faulty, the module in which the fault occurs reports the fault to the servicecontrol module and alarm module. The service control module and alarm module analyze thefault information. Then the service control module reports the fault information to the underlyingmodule for further handling. The alarm module reports the fault information to the device alarmindicator to generate visual alarm, and to the DeviceManager through the maintenance interfaceto display the alarm status and cause.

Figure 1-1 shows the event signal flow figure of the storage system.

B

Backup A periodic operation performed on the data stored in the database forthe purposes of database recovery in case that the database is faulty. Thebackup also refers to data synchronization between active and standbyboards.

Bandwidth A range of transmission frequencies a transmission line or channel cancarry in a network. In fact, the bandwidth is the difference between thehighest and lowest frequencies in the transmission line or channel. Thegreater the bandwidth, the faster the data transfer rate.

Baud rate The number of times per second the signal can change on a transmissionline. Commonly, the transmission line uses only two signal states,making the baud rate equal to the number of bits per second that can betransferred. The underlying transmission technique may use some of thebandwidth, so it may not be the case that user data transfers at the line'sspecified bit rate.

Bit error An incompatibility between a bit in a transmitted digital signal and thecorresponding bit in the received digital signal.

Bit error rate The percentage of bits that have errors relative to the total number ofbits received in a transmission.

239

Write back A caching technology in which the completion of a write request issignaled as soon as the data is in cache, and actual writing to non-volatilemedia occurs at a later time. Write back includes an inherent risk thatan application will take some action predicated on the write completionsignal, and a system failure before the data is written to non-volatilemedia will cause media contents to be inconsistent with that subsequentaction. For this reason, good write back implementations includemechanisms to preserve cache contents across system failures(including power failures) and to flush the cache at system restart time.

Write through A caching technology in which the completion of a write request is notsignaled until data is safely stored on non-volatile media. Writeperformance with the write through technology is approximately that ofa non-cached system, but if the data written is also held in cache,subsequent read performance may be dramatically improved.

Z

Zone In the fiber channel, a collection of the N_Port or the NL_Port whichcan communicate with each other in the optical network. Only theN_Port or the NL_Port in the same partition can communicate with eachother through the optical network.
