siCloud delivers enough IOPs for VDI, enough network storage bandwidth for VMs, and tightly-coupled compute nodes for the most demanding virtualized HPC workloads. Its balanced, no-compromise architecture provides outstanding performance, service, and value.

siCloud solutions are built for long-term utilization. Open Source software and standard drivers deliver on our Bricking Not Included promise, ensuring that once-useful systems won’t become outdated or obsolete.

siCloud solutions are powered by:

  • Unison, our scalable storage for fast access to VMs and associated data,
  • Tightly-coupled nodes based on our JackRabbit and siFlash appliances for the highest performance.
  • Our siRouter virtual switching with a 4 µs port-to-port NAT and 578 Gbps backplane BW.

siCloud also provides software-defined flexibility for virtual or physical machines using Linux Containers, KVM, Smart Zone, and bare-metal provisioning to match the environment to the application.
