Scale Computing was founded in 2009, building a scale-out, software-defined storage system that’s used as the foundation for their HC3 Hyperconverged Infrastructure (HCI) appliance solution. The HC3 platform is a cluster of three or more single- node appliances that run the company’s “HyperCore” software at the Linux kernel level, not as a VM like most other HCI solutions. Each node runs a built-in hypervisor, a KVM-derivative, that’s included with the system, along with a migration utility to move VMs from other hypervisors. In fact, there is no choice to use VMware, Citrix or Hyper-V.
An HC3 cluster is comprised of three to sixteen 1U appliances, each containing up to 8 hard disk drives and SSDs for a maximum raw capacity of just over 18TB per node. Scale Computing’s solution supports flash storage as a tier, not a cache, and features an automated tiering software that moves data based on priorities set for each VM.
HyperCore is designed around the company’s proprietary data distribution architecture “SCRIBE” (Scale Computing Reliable Block Engine) that spreads data blocks of selected redundancy around the cluster in a variable RAID 10 type of protection. SCRIBE presents these blocks directly up to the hypervisor, eliminating additional file system layers in the stack to maximize performance and simplify data management.
The HyperCore operating system runs on each node for installation, operation and management. Like all hyperconverged solutions, HC3 is designed for ease of use and rapid deployment. “OneTouch” features configure all resources through a web portal to match applications and set the needed thresholds for the environment during deployment. The company also has a DR-as-a-Service offering in which users can replicate and store VMs in the Scale Computing cloud and then restart them in the cloud in the event of a primary system failure.
