High performance

Supports the entire range of Intel ICE Lake processors with frequency up to 3.6 GHz. DDR4 technology, the ability to expand memory up to 12 TB. Provides computing power that meets the high computing requirements of applications such as blockchain, cloud computing, big data and virtual computing.

Reliability and stability

  • A truly fault-tolerant architecture has been implemented, including power supplies and fans.

  • Support for modern OS: Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, CentOS, Ubuntu,
    FreeBSD and virtualization systems: VMware ESXi, Linux KVM, Windows Hyper-V.

Flexible capabilities for organizing data storage and network I/O subsystems

Up to 16 slots DIMM.

Up to 12 х 3,5″ + 2 задних 2,5″ hard disks hot-swappable.

10 slots PCIe 4.0

Remote control

All vStack-R servers are equipped with an integrated management controller (Baseboard Management Controller, BMC) with support for IPMI 2.0 remote management and monitoring interface.
The operation of BMC does not depend on the server operating system and provides the following features through dedicated 1Gb RJ45 ports:

Configuring server hardware settings, including BIOS and hardware RAID.


Real-time monitoring of the system status.


KVM over IP – remote access to the server's graphical console.


Virtual Media – remote connection of virtual media (CD/DVD images) to the server.


Power management: on, off, reboot.


Display of temperature sensor readings.


Secure access via SSL.


Multi-user access, including integration with Active Directory.
