General

To build cloud services, our company uses Enterprise-level equipment from the world's leading manufacturers (Cisco, NetApp). They are located in data centers that meet the Uptime Institute TIER III international quality standard: Equinix AM2 (Amsterdam), NNJ3 (New Jersey), DataSpace (Moscow), beCloud (Minsk), and Kazteleport (Almaty). We are constantly expanding our geographic presence.

The architecture of our services is designed to have no single point of failure. This means that all critical components (Internet providers, network infrastructure, computing hosts and storage systems) are protected at the hardware layer and configured with automatic switching.

Cisco Blade Servers

Cisco UCS is considered one of the best platforms for building cloud environments. It has a single system for managing hardware components, automatic recognition of added "blades" and an advanced software API.

Virtual servers are hosted on the following servers:

  • B480 M5 with four 18-core Intel Xeon Gold 6154 processors (72 cores per socket), 1024 GB DDR4 RAM;
  • B200 M4 with two 20-core Intel Xeon E5-2698 v4 processors (40 cores per socket), 512 GB DDR4 RAM in Minsk.

Cisco UCS Series servers are housed in an intermediate casing called the “chassis”. Each chassis contains 4 power supplies that back up each other, 8 cooling system modules, and 2 Fabric Extender modules to provide communication with the switches. Each component supports a hot-swap feature.

NetApp Data Storage Systems

High-performance NetApp AFF A300 disk arrays with fast solid-state drives (SSDs) deliver the disk space for virtual machines.

A300 storage system with Intel Broadwell DE multi-core processors use high-performance RAM and non-volatile NVRAM and provide an availability level of 99.999% or higher.

Data, available on a disk array, is stored and backed up using three physical hard drives, which are located at the maximum distance from each other. This ensures the maximum safety of your data.

For backup and long-term data storage, we use Netapp E2860 disk arrays built on hard drives with NLSAS interface.

Network connectivity and equipment

Redundant high-performance Cisco ASR 9001 routers are linked with internal switchboards, Cisco Nexus 93180, at the network edge of each site to avoid a single point failure.

We use Cisco Fabric Interconnect switchboards to connect the Cisco UCS chassis to the network switches. It ensures rapid switching at high speeds with no packet loss and with extremely low latency.

Models we use:

  • Cisco UCS 6332UP Fabric Interconnect 40 Gbit/s;
  • Cisco UCS 6454 Fabric Interconnect up to 100 Gbit/s.

Internet access is provided by connecting two separate providers to two uplink ports, via different physical routes. The routers continuously monitor the availability status of one another. If one of them goes down, the entire traffic processing load is transferred to the other router to establish a persistent link between the cloud and the Internet.

1.5x better performance

Compare the Geekbench 4 score of Serverspace VMs with the others cloud providers. Implementation of real tasks on servers with 1 vCPU and 1 GB memory.
