correct connection string
We have two Centera configured as cluster with 4 nodes
The nodes have access,replication,management,storage as NodeRoles configured
Each Centera have 4 IP Adresses configured and we have 5 pools
Pool 1 to Pool 5
The replication is bi-directional
We use Easy archive and the description of the connection string in the Admin Guide of Easy Archive is not really clear for me.
Centera A have the IPs
10.10.10.10, 10.10.10.11,10.10.10.12 , 10.10.10.13
Centera B use
10.10.10.14, 10.10.10.15, 10.10.10.16, 10.10.10.17
I want configure all IP Adresses from both Centera Systems in my Storage Provider for best Performance and for highest availability
Can I configure the follow connection strings in the Storage Provider ?
Is this conform with EMC Centera ?
Connection String for Pool1
“10.10.10.10, primary=10.10.10.11, primary=10.10.10.12, primary=10.10.10.13, secondary=10.10.10.14, secondary=10.10.10.15, secondary=10.10.10.16,
secondary=10.10.10.17, ?D:\EASY\centera-pea-file\Pool1.pea”
Connection String for Pool2
“10.10.10.11, primary=10.10.10.12, primary=10.10.10.13, primary=10.10.10.10, secondary=10.10.10.15, secondary=10.10.10.16, secondary=10.10.10.17,
secondary=10.10.10.14, ?D:\EASY\centera-pea-file\Pool2.pea”
Connection String for Pool3
“10.10.10.12, primary=10.10.10.13, primary=10.10.10.10, primary=10.10.10.11, secondary=10.10.10.16, secondary=10.10.10.17, secondary=10.10.10.15,
secondary=10.10.10.14, ?D:\EASY\centera-pea-file\Pool3.pea”
Connection String for Pool4
“10.10.10.13, primary=10.10.10.10, primary=10.10.10.11, primary=10.10.10.12, secondary=10.10.10.17, secondary=10.10.10.14, secondary=10.10.10.15,
secondary=10.10.10.16, ?D:\EASY\centera-pea-file\Pool4.pea”
Connection String for Pool5
“10.10.10.10, primary=10.10.10.11, primary=10.10.10.12, primary=10.10.10.13, secondary=10.10.10.14, secondary=10.10.10.15, secondary=10.10.10.16,
secondary=10.10.10.17, ?D:\EASY\centera-pea-file\Pool5.pea”
what I want to achieve with it is a static round robin
I want spead the pools over the four IP's on Centera A, when one IP failed must the Application use the next primary IP Address.
When the Centera A is unreacheable must switch the Apllication to the first secondary IP Address (Centera B)
Is that possible or what is the best way
Thanks alot
Andreas
