Low Cost Virtual Private Servers (VPS)
Our Virtual Private Server (VPS) technology gives you the benefits of your own private server including root access without paying the price of a dedicated machine. Each VPS performs and executes exactly like a standalone server for its users and applications- it can be rebooted independently and has its own root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.

You have an entire server to yourself- you may add additional users and give accounts on your system to other people. You can host any number of different web sites, email accounts and domains on your server for you or your customers.

The attractive pricing for these servers is made possible by technology that allows us to segment enterprise class servers into multiple, independent servers - each one a completely autonomous system.

VPSs behave exactly like an isolated standalone server
It manages its own processes, users, files and full root access
It has its own dedicated IP address(es), port numbers, tables, filtering and routing rules
It has its own configuration files for the system and applications software
It has its own versions of system libraries and can modify existing ones
It can install its own application software or custom configure/modify root application software
VPSs advantages compared to a shared hosting service
Guaranteed CPU, Memory and network resources
Full root access
Install and manage your own applications
Isolation and Advanced security
Host multiple domains
Manage your own web and mail server
Start and stop applications
Reboot your own VPS (currently, Linux VPS only)
Performance
At any given moment you will have access to a large majority of platform resources. This is because usage is highly non-parallel, and because server instances can be transparently moved from one physical server to the next.

All storage is hardware RAID for performance and fault tolerance.

We have in place sophisticated methods of performance "smoothing" between our host machines that allows us to transparently place each server instance in an optimal performance environment. Translation: your server will never be slow due to the operations of other server nodes in the cluster.
Unique Benefits
VPS servers have unique benefits over traditional colocation.

You are not responsible for the underlying hardware, and thus do not need to respond to equipment failures. If you crash or incapacitate your server, you do not need to wait for POST operations and other boot time delays. Further, your file system is not in jeopardy due to crashes or halts - there is no need to `fsck` or otherwise maintain the file system after a crash.

The hardware your server exists on is much more fault-tolerant than a machine you would collocate on from a traditional provider. It is common for our servers to have two or more independent power supplies each attached to a different physical circuit, four or more independent and hot-swappable fan units, and RAID HDDs running on duplexed adaptors. Each of our systems can withstand a large number of component failures without interrupting service. Standard co-location vendors cannot offer this.

There is a performance benefit as well - no matter how fast the single processor non-RAID systems offered by other vendors are, they do not offer anywhere near the performance of dual or quad-processer servers running with fast RAID arrays. Sizing and performance tuning manuals conclude that performance issues are almost always due to disk I/O. The disk I/O on our systems blows away that of standard rackmount co-lo servers offered by other vendors.

In the event of some catastrophic data loss, we can simply restore the previous nights image of your server, and restart it - a process that can take as little as ten minutes to complete. This means you do not even need to do your own backups (you may wish to backup your data more often, or to a separate site - if so, let us know and we can help). Note that we back up only the list of directories that you specify - you will receive details in your welcome email.
