GridServer for Linux and virtualization environments

In Linux, the Zstor GridServer is a recommended system. Most datacenters estimate the flexible configuration options that meet exactly the requirements both in terms of performance and price. The simple management of the separate IPMI 2.0 interface optimized centralized management as well as the services frankly design, especially the easy to change motherboard tray is appreciated. The necessary internal approvals for use with all popular Linux derivatives, like Ubuntu, SuSE, RedHat, CentOS, or ZFS OSes like NexentaStor and OmniOS, are performed. For server virtualization within Microsoft HyperV, VMware or Proxmox configurations are available to support up to 44 hardware CPU cores providing the necessary performance.
