The HP Intelligent Infrastructure Analyzer Software (IIAS) v2 is an online monitoring and diagnostic solution intended to manage the physical layer of a Storage Area Network (SAN) consisting of HP StoreFabric B-series and/or H-series Fibre Channel switches and directors, HP 3PAR StoreServ Storage and HP StoreFabric Fibre Channel HBAs. It is also supported on select HP Networking (HPN) Switches. It uses industry-standard protocols (such as SNMP, SMI-S, Telnet) to monitor the physical layer across the SAN and to diagnose changes/events in Small Form-factor Pluggable (SFP) transceiver states/characteristics. It also presents the SAN topology, inventory and diagnostic information to the user in real-time. It is targeted at customers who have HP 3PAR StoreServ Storage, HP StoreFabric Fibre Channel HBAs and/or HP storage networking hardware in their SAN. In addition, customers with select HP Networking switches can also make use of the monitoring and diagnostic capability of HP IIAS. The HP Intelligent Infrastructure Analyzer software can be used to monitor and diagnose the physical layer of the Storage Area Network (SAN) in real-time, with an emphasis on the Small Form-factor Pluggable (SFP) transceivers on FC Switches and 8 and 16 Gb FC HBAs in servers or Storage arrays. The product can be used to detect potential failures in the SAN for root cause analysis and failure impact assessment and is therefore highly beneficial for enterprise SANs, where SAN management becomes cumbersome and tedious. HP Intelligent Infrastructure Analyzer Softwareimproves the total data center quality experience by predicting switch optical link failures before they are reported and aims to reducethe cost incurred due to application downtime.
