Scale Computing HC3 Hyperconverged Infrastructure – Product Brief

Last updated November 8th, 2019 for updates to EvaluScale table. Concise 7-page overview of hyperconverged product Scale Computing HC3. Covers potential, usage, technical specs, and commentary on strengths/concerns.

Scale Computing was founded in 2009, building a scale-out, softwaredefined storage system that’s used as the foundation for their HC3 Hyperconverged Infrastructure (HCI) solution. The HC3 platform is a cluster of three or more single- node systems 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 KVMderivative, 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 or 2Unodes, each containing up to 9 hard disk drives or 4 SSDs. Storage configurations include hard drive only, hybrid and all-flash. 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.
The HE series of nodes are single-CPU, 4-drive nodes designed for smaller locations or remote offices. These lower-cost models are available in 1U rack or tower form factors.
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. This architecture also reduces total resource requirements which enables HC3 to run with lower core-count CPUs and less memory.
