Glossary

application-specific integrated circuit

ASIC. An asynchronous transfer mode (ATM) local area network/ wide area network (LAN/WAN) circuit using cell relay transport technology. ASICs are designed for a specific application or purpose, such as implementing the lower-layer Fibre Channel protocol (FC-0). They are particularly suited to sending video and audio information, as well as text. ASICs differ from general-purpose devices such as memory chips or microprocessors.

attribute

In S/390 mode, the connection status of the address on a configuration matrix: allowed, blocked, or prohibited.

Audit Log

Log summarizing actions (audit trail) made by the user. There are two types of Audit Logs: the director or switch Audit Log, and the HAFM Audit Log.

(1)Director or switch Audit Log. Log displayed through the Product Manager application that provides a history of all configuration changes made to an individual director or switch from the respective Product Manager application, a simple network management protocol (SNMP) management workstation, a Fibre Connection (FICON) or open systems host, or the maintenance port. This information is useful for administrators and users. Contrast with HAFM Audit Log. See also Event Log; Hardware Log; Link Incident Log; Threshold Alert Log.

(2)See HAFM Audit Log.

availability

The accessibility of a computer system or network resource.
