Virtual Servers

We use OpenStack Cinder as abstraction layer to data storage system. It supports many platforms and since it is opensource, you can move your stuff to any provider you want. Xentime will provide full copy of data and meta-data on request from you. Ther's no vendor lock-in.

Also we offer only fixed fee services. You do not need to worry when load increases.

Another issue Xentime has addressed was transparency. Most of companies do not care for information security enough nor even disclose details on how they store your data.

With opensource software it becomes more clear how your data are stored. Nevertheless, below you will find more details on what technologies we use and how they work.


Networking

Your VPS will have a static, white IPv4 address. It allows you to use any protocol you want without limitations.

Ethernet frame leaves your virtual machine through eth0 network interface and through bridged Linux device goes strangt to Ethernet Switch.

On the physical level we use Cisco switches and routers.


VPS Storage Backend

VPS data are stored on mirror RAID. We use LVM2 volumes, available through OpenStack's Block Storage service, called Cinder.

Hard drives in use are Wester Digital Black and Samsung 850 Pro.


Object Storage

Xentime offers a file storage service as well. When you upload files, OpenStack Swift stores those files in distributed object storage system. Then you can share files using links or leave them in private area.


Other Software

In Xentime we use Debian, but we have proficiency with RedHat-based operating systems, such as Centos, Scientific Linux, Fedora and others. Also we offer OpenBSD, NetBSD and FreeBSD pre-installed operating systems, that all have proven stability and decent level of security.

Our control panel and website are implemented using Django python framework, Celery asynchronous task queue manager, RabbitMQ message broker and PostgreSQL relational database management system.

We use best practices in programming to offer you the fastest, most stable and secure system.


Traffic

Xentime never changes routes, nor prioritize traffic. But in some rare cases we have to limit bandwidth.
