Setting up HUR is challenging. Without Experience, or assistance from services you will probably have many challenges. HUR operates in a very wide range of environments with many options.
1. What is the minimum version of Firmware for HUR?
I would recommend 70-06-20. You should ALWAYS go with the latest available microcode! It is safer to use the most recent code than any other version.
2.How HBA drive is related with HUR ?
I dont understand this phrasing?
3.What System Option mode is require for HUR to setup ?
There are many HUR SOM that are used depending on the desired behavior, and the performance goals. That is one reason to use Professional services to size and configure HUR. Additionally some SOM for HUR require approval from support to enable.
4.What about license for replication ?
Yes, a License is required to use HUR.
5.What is the thumb rule to design journal for HUR ?
JNL should be on dedicated RG, that are very fast. If your JNL are slow, then it will slow down the performance of host I/O. Again there are sizing tools that Professional Services uses to generate the required configuration.
6.How the rate of change induced by IOPS / throughput is related with journal volume , how the value will be factored in Journal volume calculation ?
IOPS, %Write, % Change, and MB/s are all factors in sizing HUR. These all help to tell you the number of links, Number of JNL, Number of PG, dedicated MPB or not, etc that you need.
7.How many IP / physical port is required for setting up minimum FCIP tunnel ?what is the VLAN requiremnet ? What is the expected data throughput expected in a FCIP tunnel ? What are the option to increase the same?
At a minimum HUR needs 2 physical ports on each VSP. The FCIP tunnel should have a high minimum guaranteed rate. Slow FCIP links are the number one cause of problems.
Also if I get an overall idea for planning of the DR starting from application --> server --> storage application --> Dr drill / DR activation --> DR failback etc . that would be a great help.That is one of the things that is provided by Professional Services.
