Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.
I have done some checks prior to the main server install, and found that CentOS 5 doesn't come in ia64 format yet, which is what my PowerEdge 3250 is.
So I'm going to have to use CentOS 4.5 ia64 version for now.
I have a question. I have found out that the LSI Logic SCSI Controller in my PowerEdge 3250 isn't true hardward RAID and doesn't support hot swap on the drives.
Would it be better to use its limited software RAID features (not that software RAID is reliable!) or would it be better to run some kind of automated back up script to copy the database, user files, plesk files and so on to the second drive once a day.
Performance, nobody optimizes anything for ia64. A lot of packages tend to be i386 in compat mode. Driver support is nearly non-existent. What you're getting (best case) is a slower, less stable i386 system that uses at least twice the amount of ram for any regular operation.
