Miva 4.x & an HA Environment

[swiftmv]

Hello all,

I have a group of technicians saying that we could/should run Miva in an "HA environment".

As this is all out of my league, I thought I'd put it to this Community to see if anybody has had any experience in running this, or even thinking about it.

What are the advantages and disadvantages? Or is it just a "don't go there" situation. Reason(s)?


many thanks,
Michael

Merchant 4 doesn't lend itself to high availability because of its reliance on file-based databases. The only way to run it in HA is on shared storage and the large amount of small I/O on the file-based databases results in poor performance on most types of shared storage unless you do a 2 gbit fiber channel SAN but that of course is not cheap. You also need a load balancer in front of the web servers.

Merchant 5 gets a lot closer to easy HA since many things are done in mysql; you still need to worry about replicating the static content to your web servers, including the page template files that are created on the fly when changing the pages in the admin, but if you don't change your store often, it will work great in an HA environment.
