The following best practices and general advice are recommended when using Vertica Eon Mode with Dell PowerScale.
Description | Details |
DNS Specific Configuration | The Microsoft DNS server caches the Node IP addresses for queries made with a time to live (TTL) of one second. If there are multiple recursive queries for the same DNS zone name within the same second, the DNS server responds with the same node IP for the client connection requests. One option is to use the SmartConnect service IP as the preferred DNS server and the Domain DNS server as the alternate DNS server IP. Another option is to use an alternate DNS implementation. |
Load Balancer (optional) | Dell recommends using GSLB clustering if an IP Load Balancer is used in place of SmartConnect. ECS Connection manager supports GSLB clustering to leverage DNS and distribute traffic across the load balancers, therefore combining resources to deliver the required performance. |
