HC3 Virtualization Platform Deployment


The HC3 virtualization platform brings together servers, storage, virtualization, and disaster recovery into a single, feature rich solution. This guide describes all of the features that make HC3 the perfect infrastructure solution for any datacenter.


The heart of the HC3 platform is the HyperCore operating system which includes a fully integrated KVM-based hypervisor with our patented block access, direct attached storage system called SCRIBE. SCRIBE includes HEAT to automate tiering across our own hybrid flash storage architecture.

HC3 Web Interface

The entire HC3 solution including hardware and software is managed from a single web interface that can be accessed from any node in a cluster. The simple interface design allows both storage and compute resource management and virtual machine management from a single pane of glass. Resource statistics are displayed in real-time along with IOPS, both per VM and cluster wide. VM consoles are also immediately available from the web interface.

Remote Cluster Management

Multiple clusters or single nodes across multiple sites may be managed within the HC3 Web Interface. The remote systems can be monitored for errors, warnings, or other issues at a glance. Manage dozens of sites from a single interface for simple, scalable management

Multi-User Management

For clusters and sites with multiple administrators, HC3 features multi-user administration to allow each administrator a unique account and login. Multiple administrators can be managed with unique logins and activity logging to help troubleshoot issues based on administrator activity.


SCRIBE is a wide-striped storage architecture that combines all disks in the cluster into a single storage pool that is tiered between flash SSD and spinning HDD storage. Blocks are striped across all nodes in a cluster redundantly to protect both against individual drive failure and node failure. The use of every drive through wide striping gives a performance advantage to every VM on the cluster. Performance is also enhanced through direct block access because of the direct integration between the storage and the hypervisor resulting in Hypervisor Embedded Storage. There are no inefficient storage protocols that would normally be found in SAN or NAS-based storage solutions including Virtual Storage Appliance architectures.


HyperCore Enhanced Automated Tiering is the part of SCRIBE that manages data efficiently between the flash SSD tier and the spinning HDD tier in the cluster storage pool. It prioritizes blocks of data on SSD or HDD based on a I/O heat map that tracks I/O against each virtual disk. Although HEAT is primarily automation happening behind the scenes, it provides the ability for the user to tune the relative priority of every virtual disk in the cluster to further optimize the SSD usage where it is needed the most. You can literally turn it to 11.


SCRIBE includes data deduplication that eliminates duplicate blocks on virtual disks, significantly increasing disk capacity. Deduplication is done with minimal impact to running VMs. Reducing the storage footprint of data to increase your data storage capacity.

Live VM Migration

VMs on HC3 clusters can be non-disruptively migrated between nodes with no downtime. This not only allows for rebalancing resource allocation across the cluster but also allows VMs to be relocated automatically during our rolling update process for the HyperCore OS firmware.

Non-Disruptive Rolling Updates

HC3 receives software/firmware updates directly to the HC3 Web Interface where they can be applied automatically with no downtime. A single click updates the hypervisor, the storage system, the firmware, and any other part of the complete HC3 system. The automated update process will automatically relocate VMs between nodes to free up the nodes, one at a time, to be updated. When all of the cluster nodes are updated, the VMs are returned to their original configuration across the cluster.

VM High Availability

If a node fails within the cluster, all VMs running on that node are automatically failed over to one of the remaining cluster nodes. Failover happens within minutes for minimal disruption. After the node has been restored or replaced, the VMs can non-disruptively be live migrated back if desired.

Self Healing

The HC3 architecture is built with layers of redundancy, such as dual active/passive network ports, redundant power supplies, and redundant block storage striped across all cluster nodes. Intelligent automation handles drive failures and node failures, redistributing data across remaining drives and VMs across remaining nodes and automatically absorbing replacement drives and replacement nodes into the resource pools.

Cluster to Cluster Replication

VMs can be replicated between two HC3 clusters with native, built-in replication. Replication can be local or remote across any distance and can be configured to replicate changes as often as every 5 minutes. Granular selection of VMs for replication allows a range of between one and all of the VMs on a cluster to be replicated. Replica VMs on the target cluster can be booted up within minutes in the event of a failure of the VM on the primary cluster.

Snapshot Scheduling

VM snapshots can be scheduled intuitively and flexibly from the HC3 Web Interface. Schedules can include multiple rules spanning schedule intervals based on minutes to months. Schedules are created as templates that can be assigned to one or more VMs across a cluster.

Thin VM Cloning

HC3 uses a unique thin cloning technique that allows cloned VMs to share the same data blocks as their parent VM for storage optimization, but with no dependencies. If the parent is deleted, the clone is not affected and continues operating without disruption.

Rapid, Easy Deployment

An HC3 cluster can be racked, cabled, powered on, configured in a matter of minutes, and VMs can be deployed and running in under an hour. Manage from your prefered web browser to the HC3 web interface. There is no extra software to install, simply upload ISOs to deploy VMs with your favorite guest OS.

Non-Disruptive Scale-Out

When a cluster needs more resources, a new node can be added within minutes without any downtime to the existing nodes or VMs. After racking, cabling, powering up, and assigning an IP address, the new node and its resources are seamlessly absorbed into the cluster, including the storage capacity being immediately added to the storage pool. Adding nodes results in an immediate performance increase to the running VMs as the resource pool is expanded.

Mix and Match Nodes

With HC3, any two cluster nodes across all HC3 families (1000, 2000, and 4000) can coexist in the same cluster and contribute to the cluster storage pool. This allows clusters to grow not just linearly but in whatever way is needed or desired. This support for different size cluster nodes can facilitate non-disruptive upgrades to the infrastructure by adding newer, bigger nodes and then retiring or repurposing older small nodes if desired, all while keeping the VMs running.

Remote Support Access

HC3 offers a remote access point exclusive to ScaleCare support to help diagnose support issues and take corrective actions if necessary. This remote access dramatically speeds up support issue resolution by giving ScaleCare support engineers the ability to see issues firsthand and in real time.

Use Cases:

HC3 virtualization infrastructure can be used in a variety of ways but here are some of the most common use cases for our HC3 customers.

Virtualization Without Licensing

With HC3, the hypervisor is included with no additional costs or licensing fees. HC3 customers who had paid VMware licensing fees in the past see the value in becoming free of these extra fees for lower costs and more budget freed up.

Backup and High Availability

HC3 customers see the value of built-in backup and high availability after their legacy solutions had proven ineffective despite being an added cost. With options for offsite and cloud-based DR, HC3 customers have peace of mind that their VMs and data are protected.

Lowering Infrastructure TCO

Our customers have all been looking to lower their total cost of ownership (TCO) for IT infrastructure. We have designed HC3 to reduce IT infrastructure costs in almost every way. Many of the hidden costs of IT infrastructure such as unplanned downtime, management, maintenance, training, and consulting are virtually eliminated with HC3. Other solutions that integrate multiple vendor solutions only add complexity which increases costs. We believe HC3 is a better way, and our customers agree.

Edge Computing & Distributed Enterprise

HC3 customers who manage remote sites see the value in HC3 for both ease of use and low entry cost. The ease of use, rapid deployment, self-healing, and remote web-based management capabilities mean that their remote sites can be managed more efficiently and with less cost.

Virtual Desktops (VDI)

The low cost, ease-of-use, and scalability of HC3 make it perfect for VDI infrastructure. Scale Computing has validated our solution with VDI vendors to allow our customers to implement VDI from the SMB to the enterprise.
