1 ADX Software Updates and the Application Resource Broker (ARB) Introduction

2 Objectives Upon completion of this module, you will be able to: Discuss ADX licensing Describe the Application Resource Broker (ARB) List the web management enhancements Identify and gateway support Discuss the Router Advertisement (RA)-based default route Describe the Response Time Predictor enhancements Define the shared Layer 2 active-active Transparent Cache Switching (TCS) implementation Describe the SNMP weighted predictor for TCS 2

3 ADX: Software Updates Capacity on demand with ADX License Activation Feature Activation (v12.1) Used to enable premium features (e.g. Layer 3, GSLB) Software Licensing (v12.2 and above) Includes feature activation used to enable premium features Upgrade licenses are now available for specific ADX platforms which can be installed by customer Base licenses are pre-installed at the factory With the v12.2 release the software licensing structure now includes both feature and upgrade licensing capabilities for select ADX platforms 3

4 ADX: Software Updates (cont.) ADX 1000 Capacity-on-Demand Licensing Model The ADX 1000 family includes four base models of varying processor and port capacity, based on the full ADX 1000 platform hardware and operating system software ADX (1) application core and (8) 1 GbE ports ADX (2) application cores and (16) 1 GbE ports ADX (4) application cores and (16) 1 GbE ports ADX (4) application cores, (16) 1 GbE and (2) 10 GbE ports 4

5 ADX: Software Updates (cont.) Unlimited versus Trial Licensing Two types of licenses supported Unlimited (perpetual and never expire) Trial (Only for Upgrade Licenses 45 days) Example Unlimited and Trial licenses for 1U ADX LIC-2PPLS (Perpetual License) ADX TRL-2PPLS (Trial License) ADX LIC-10G (Perpetual License) ADX TRL-10G (Trial License) Example Unlimited and Trial licenses for Chassis ADX-CH-LIC-PREM (Perpetual License) ADX-CH-TRL-PREM (Trial License) 5

16 Web Management Enhancements

17 Web Management Enhancements Application Template and Software Upgrade Generic HTTP Template Built-in generic HTTP Template which helps to facilitate the configuration of HTTP Server Load Balancing Code Upgrade through web UI Copy software image from TFTP Server Reboot the device 17

18 Additional ADX Feature Enhancements SYN-Proxy support and Gateway support RA based default route Response Time Predictor Transparent Cache Switching

19 SYN-Proxy Enhancement In previous ADX releases, we offered line-rate SYN-attack protection for IPV4 traffic. This has now been extended to the protection of IPV6 traffic Enabling SYN-Proxy is the same as IPV4 no new commands have been introduced SYN-Attack is handled by hardware at line-rate Supports both 664 and 666 deployments 19

20 IPv6 Gateway Support Overview ADX supports two flavors of the IPv6 gateway 20

21 IPv6 Gateway Support Binding Combinations ADX IPv6 gateway does not support IPv4 VIP bound to IPv6 server(s) Note: Same IPv4 server can be bound to IPv6 VIPs as well as IPv4 VIPs 21

22 ADX RA-based Default Route Upstream Routers IPv6 Router Advertisement (RA)-based alternative to VRRP 1 Upstream routers send periodic RAs with different preferences (high, medium or low); default value is medium Set RA-interval to be a value lower than the required failover time 22

23 Response Time Predictor Enhancement Overview Review : The ADX uses a parameter called the predictor to determine how to balance the client s traffic across the servers ADX Connection Distribution policies: Round robin Least connections (default) Weighted distributions (Updated) Response time Response time/least connections Least local connections In previous releases traffic was always sent to the server with least response time. As of v12.2 the response time of the server will be used as a dynamic weight in load balancing decision. 23

24 Response Time Predictor Measurement of Response Time and Associated Weight Based on response time of health check packets If Layer 7 Health Check is enabled, application response time If Layer 4 Health Check is enabled, SYN/SYN ACK RTT Health Check must be enabled to make it work The response time predictor is only applicable to TCP traffic (for both well-known or non-well-known ports) The load balancing decision is based on response time weight instead of the actual response time Response time weights are derived from actual response time measurement, the smaller the response time, the larger the response time weight 1 24

25 Transparent Cache Switching (TCS) Enhancements Overview Shared Layer 2 active-active TCS support Operates at Layer 2 and provides for two or more cache groups directly attached split across the two ADXs Each uses all Caches in each group regardless of which ADX they are connected to Traffic may be asymmetric across the ADXs because which route the traffic may return is uncertain Sharing caches allows Link and ADX redundancy while utilizing all available caches Support an out-of-band SNMP-based polling mechanism to poll the cache servers for their load information Vendor specific MIB is available 25

26 Summary The Brocade ADX 1000 platform can be upgraded from entry level to high-end with simple license activation The Application Resource Broker enables on-demand provisioning of application resources for private clouds IPv6 to IPv4 gateway support allows for data center migration to IPv6 The failover capabilities provided by IPv6 Router Advertisements provide an alternative to VRRP deployment For additional ADX information go to learning.brocade.com and search for "ADX
