| − | 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.
