Uptime 30 days uninterrupted? Excellent news.

Is it a OpenVZ, or Xen VPS...?

1GB memory?

Does it have the flexible memory limit... up to 1.5 GB peak?

Does a swap disk exist, or zero swap for maximum speed + more risk of crash ?

Fantastic!

Even 5minutes downtime (for a reboot?) in 60 days is 99.994%. "Four 9's."

2minutes (for reboot) in 60 days = 99.99768% uptime or just round it 99.998%.... "High four 9's."

1minute (for reboot) in 60 days = 99.9988% uptime or simply 99.999% uptime. This is the holy grail ! "Five 9's."

Hi Friend7,

98 days uptime is awesome. Bravo to you and David.

Is it possible to get a full set of configuration settings for this server ?? There's a lot of other features and settings.

Anti spam.. are you using amavis or no?? Which settings are you using?

Intrusion detection.. are you using snort or no?? ...

etc..

Are you using multiple organizations (companies) with separate domain and zarafa instance, for each organization ??

Hello,

It is a DNSSEC Server with PowerDNS and PowerAdmin.

It has MySQL Database Replication with SSL Encryption.

It binds 10 Websites.

It has "anti-hacks" everywhere and I have posted about it.

Also, The refresh setting is 350 MB RAM for PowerDNS

The Lower Config settings are above.

I have another one "in progress" with more applis

Thanks. I want to try one with minimal.. or medium.. RAM, 1-2GB.

Are you hosting separate organizations, each organization with its own .com, freewebs, and separate email system??

Did you think of testing many LXC containers, each with one zarafa community edition + one email domain + one organization ??

I have a Master Server with an Organization and multiple domains.

This is a full-featured server.

It has

Zarafa
Full Anti-SPAM (Milter Greylist, Amavis, Clam AV, SpamAssassin, Instant Ip Tables, Filters, Plugins and etc )
Postfix Multi-instances / System
Snort (stopped)
Freewebs
DNSSEC DNS Server with PowerDNS
PowerAdmin
MySQL Database Replication with SSL Encryption
Full Geo Anti-DOS/DDOS ATTACKS
Anti-hacks
iptables

Etc ...

I think you could not have Zarafa/Amavis in a small VPS. They could get 2 GB RAM.

Also, LXC is for Dedicated Server or maybe a very big XEN VPS
I would not try it in small container.

I think that LXC containers could work well in a
Sandy Bridge Server because it has Up to 17% more CPU performance
but I have not tried yet ...
Best Regards,
Friend7
