Cluster NetEye – failover anche sui canali di notifica GSM
Per ottenere, oltre la completa replicazione dei dati con RAID, anche una flessibilita’ di continuita’ dei servizi NetEye in caso di problemi, tanti clienti hanno installato un cluster con tutti i servizi di monitoraggio, capacity view/management ed asset management (inventario hw / software ) in failover.
La configurazione di questo cluster comprende la funzionalita’ di garantire la continua replicazione dei dati tra i nodi, ma anche la gestione automatica di spostare il servizio verso l’altro nodo in caso di problemi.
Per un Ns. cliente e’ stato implementato di recente una logica avanzata che comprende anche il failover sui canali di notifica tramite modem GSM. Questa logica riconosce il controllo della corretta funzione e reativita’ del gateway GSM sul nodo attivo. In caso di problemi ( il modem perde il collegamento al provider GSM, la SIM si blocca, etc ) il cluster service va a verificare la corretta disponibilita’ del servizio GSM sul secondo nodo NetEye e se ( e solo se ) questo riporta un risultato positivo il servizio NetEye viene attivato su questo nodo. Per arrontondare questa funzione viene inoltre inviata una SMS di notifica all’amministratore di rete attraverso il modem del server remoto.
Questa logica impedisce che avvenga un cluster “failover loop” in caso di problemi genereali sulla rete GSM e garantisce inoltre, insieme a determinate configurazioni di recovery, di salvare ed inviare in questo caso gli sms falliti una volta tornato disponibile almeno un gateway.
After my graduation in Applied Computer Science at the Free University of Bolzano I decided to start my professional career outside the province. With a bit of good timing and good luck I went into the booming IT-Dept. of Geox in the shoe district of Montebelluna, where I realized how a big IT infrastructure has to grow and adapt to quickly changing requirements. During this experience I had also the nice possibility to travel the world, while setting up the various production and retail areas of this company. Arrived at Würth Phoenix I started developing on our monitoring solution NetEye. Today, in my position as Consulting an Project Manager I am continuously heading to implement our solutions to meet the expectation of your enterprise customers.
