Skalowanie wydajności, konfiguracje ClusterXL, SecureXL i CoreXL J. Prokop Check Point

Skalowanie wydajności oprogramowania Trzy produkty kategorii „XL”: ClusterXL: łączenie urządzeń w klastry ClusterXL LS for VPN-1 and Connectra ClusterXL VSLS for VSX VSLS Nokia IP Clustering, Crossbeam X80 itp SecureXL (Accelerated Path) Hardware: (Nokia) ADP Software: Performance Pack (SecurePlatform, Crossbeam XOS) IPSO SecureXL implementation („fastpath”, SecureXL) CoreXL: wielordzeniowa implementacja Firewall Path / Middle Path

Cluster XL Cele klastrowania urzadzeń: Zwiększenie niezawodności Zwiększenie wydajności

Cluster XL Problemy rozwiązywane przy klastrowaniu: Sieć (adresy MAC, IP) Synchronizacja (asynchroniczny routing pakietów, krótkotrwałe sesje, sposoby dzielenia sesji między węzłami)

Cluster XL z ograniczoną liczbą adresów IP

Accelerated Path (brak „wzorca” – template) Core #... Medium Path FW Queue Core #4 Medium Path FW Queue Core #... Medium Path FW Queue Core #0 Core #1 Secure Dispatcher Secure Dispatcher Performance Pack Performance Pack eth0 eth1 Syn SynAck + subsequent S2C packets Subsequent C2S packets

Accelerated Path (ze „wzorcem” – template) Core #... Medium Path FW Queue Core #4 Medium Path FW Queue Core #... Medium Path FW Queue Core #0 Core #1 Secure Dispatcher Secure Dispatcher Performance Pack Performance Pack eth0 eth1 Syn + subsequent C2S packets SynAck + subsequent S2C packets

Medium Path – IPS Traffic Core #... Medium Path FW Queue Core #4 Medium Path FW Queue Core #... Medium Path FW Queue Core #0 Core #1 Secure Dispatcher Secure Dispatcher Performance Pack Performance Pack eth0 eth1 Syn + subsequent C2S packets SynAck + subsequent S2C packets

Monitorowanie CoreXL Funkcja hash rozdzielająca sesje pomiędzy instancjami (rdzeniami): Source IP address Destination IP address Destination TCP/UDP port IP protocol number VoIP i IPSec : zawsze na instancji „0” ! Nie ma tu portu źródłowego: konserwatywna, słabo rozrzucająca funkcja Jeżeli grupa klientów pracuje za translatorem adresów na pojedynczym serwerze to wszyscy będą przetwarzani na tym samym rdzeniu.

Podsumowanie i tematy ciekawych rozważań związanych z wydajnością CoreXL jest częścią każdej instalacji wielordzeniowej (nie wymaga dodatkowej licencji). CoreXL: R65: przerwania (SPLAT kernel 2.4 / 2.6) R70: przerwania, konfigurowalna liczba instancji, fwpprof, możliwość ignorowania procesorów

Dziękuję za uwagę!
