Subject: Questions about Archiver Appliance deployment

Dear all,

We plan to migrate from Channel Archiver to Archiver Appliance for archiving in CSNS (China Spallation Neutron Source) accelerator control system.

Our platform for Archiver Appliance deployment is:
Debian Jessie 8.7, HP blade server with 512G memory and 20-total-core Xeon E5-2650 processor.

After a couple of weeks' evaluation (deployed using single_machine_install.sh), I have some questions as follows.

1. For the 512G memory, in order to have a good performance, how much memory shall I allocate to RAMDisk (for STS) and how much to JVM heap (i.e. -Xms & -Xmx options) of each of the 4 components?

2. We have two blade servers dedicated for Archiver Appliance deployment and will only archive less than 100,000 channels, so we prefer redundancy (failover) instead of cluster. Is there any information about Archiver Appliance redundancy deployment?

3. It seems that Archiver Appliance allows users to achieve configuration and operation via web UI and script (HTTP/Json), but it is not what we want in our control network. So how can I enforce restrictions to the web UI or web service so that only admin can manage?

4. We need to convert Channel Archiver files to Archiver Appliance PB files for a complete transition, so which tool will be recommended to do this? Is the ca2aa [1] still available or already obsolete? I saw there is no README or wiki for that repo any more.

5. Is there any other tool or script that is useful for performance or reliability test for Archiver Appliance?


Any suggestion is appreciated.


Thanks,
Lin
