DevUrandom: Question regarding TekTonic website

Thanks for fixing up that other page! No one on IRC or Google knew about this page, though...<br/>
Informations about SLM and VZFS on http://wiki.openvz.org/w/index.php?title=OpenVZ_vs._Virtuozzo&oldid=6042 are wrong? I dont see that topic covered on this page.
--[[User:DevUrandom|DevUrandom]] 07:18, 5 June 2008 (EDT)
: VZFS is "Higher container density" -- first item in "Main benefits". I will add the VZFS letters there :)
: easySLM is indeed not mentioned, I will fix that. Info on SLM vs. [[UBC]] was wrong -- SLM is not "vs.", it is rather an addition to [[UBC]] mechanism.
: --[[User:Kir|Kir]] 08:21, 5 June 2008 (EDT)
:: http://www.tektonic.net/vz.html is incorrect? The information there ("SLM is the answer to the problem" and below) seems to be quite extensive.
:: Maybe you want to add the letters "UBC" in addition to "User Beancounters", too? Seems as if it is a catchphrase people recognize before they know what the letters stand for.

OpenVZ vs. Virtuozzo

DevUrandom: More details about "ram management"

== Comparison ==

Many may wonder what exactly the difference between OpenVZ and Virtuozzo is.<br/>
Virtuozzo is based off OpenVZ, which means it adds a few features. Which are that?

* Management interface (GUI)
* Resource management
* SLM memory management, while OpenVZ uses UBC ("Unified Buffer Cache"), [[OpenVZ vs. Virtuozzo#SLM vs. UBC|see below for a comparison]].
* VZFS (allows for disk and memory savings very similiar to Linux-VServer's copy-on-write system called "unification")
* Commercial support

OpenVZ is mostly run by Parallels (owner of Virtuozzo) employees, who maintain OpenVZ as the core functionality of Virtuozzo.

== SLM vs. UBC ==
An example would be: With UBC a VPS may be limited to 128 iptables entries. With SLM you can create thousands of iptables entries up to their global RAM limit.
See bottom of http://www.tektonic.net/vz.html for a description of the SLM technology.

DevUrandom: Very basic Virtuozzo vs OpenVZ comparison, as recieved on IRC (the net seems to be missing something like this).
