HC3 Edge - HE150 Appliance
Q: What is the HE150?
A: The HE150 is a small form-factor platform designed to run HC3 in a variety of environments. The HE150 is a fully-functional HCI offering based on small form-factor hardware, designed to deploy a fully redundant HCI cluster for smaller workloads, generally less than 15 VMs per site.
Q: How is it different from other Scale Computing HC3 appliances?
A: The HE150 is a small form factor, designed for edge deployments. With a single drive and network port, the HE150 offers a simple configuration that can deploy quickly and easily. Redundancy and fault tolerance is provided by the native clustering within the Hypercore software.
Q: Is the HE150 available in a single-node configuration?
A: Yes. Like other HC3 deployment requirements, a replication target is required for single-node HC3. Since HE150 systems only provide a single NVMe storage device, there will be only one copy of data stored when using a single node configuration.
Q: Can we add an HE500 series appliance to an HE150 cluster?
A: HE150 appliances can only cluster with other HE150 appliances. The architectural differences (one drive per node, one NIC per node) preclude the HE150 appliances from being clustered with other HC3 appliances. Note that HE150 appliances and clusters can use built in VM replication to replicate to any type of HC3 system or appliance.
Q: What are the switch requirements / what will be supported for an HE150 cluster?
A: A HE150 cluster requires access to an available 1Gb Ethernet switch port for each node. Unlike other HC3 appliances, redundant ports are not required as the HE150 only has a single, 1Gb Ethernet port. A managed or unmanaged switch may be used. If manged switches are used, ports should be set to trunk or to specifically handle the VLAN tag configured for backplane traffic use. Please consult the latest networking guidelines for further information.
Q: Does HE150 support a direct-connected/daisy-chained backplane over Ethernet or Thunderbolt?
A: The HE150 only has a single physical ethernet interface, and therefore cannot support a direct-connected or ring topology. In the future, with the release of HC3 Edge Network Fabric v2, additional models of the HC3 Edge line which have multiple ethernet and/or Thunderbolt interfaces may support such topologies.
Q: Since HE150 backplane traffic shared a physical NIC/network with LAN/VM traffic how is traffic prioritized?
A: There is a VLAN specified for backplane traffic that is created as an internal, private network that shares the bandwidth and throughput with the LAN/VM network. Testing has shown that even under sustained high load both LAN/VM traffic and backplane traffic get fair access to the physical network port.
Q: Since HE150 backplane traffic travels over the same physical NIC/network as LAN VM traffic, are there security concerns? Can VM’s “sniff” backplane traffic?
A: The HC3 Hypervisor does not permit virtual machines to observe backplane traffic in any way. The backplane VLAN is private to the hypervisor, and those packets are filtered out prior to entering the virtual bridge.
Q: Is HE150 a fanless, ruggedized, or sealed system?
A: The HE150 is not a fanless, ruggedized, or sealed system, however, some enclosures may provide these attributes and Scale Computing is currently researching enclosure options.
Q: What rackmount or enclosure options are available for the HE150 appliances?
A: Scale Computing is evaluating options for rackmount options as well as enclosures. In the meantime, we can discuss the options we have been evaluating to see if they could meet your needs and could be purchased directly.
Q: Are HE150 nodes PoE (Power over Ethernet) ready? Can I get them or use them with SimplyNUC POE lid or other PoE switches/solutions?
A: NUCs do not support PoE natively. Third-party sellers have a variety of options to provide PoE as an option for NUCs. Scale Computing is testing out the alternatives, along with PoE switches for complete deployments.
Q: How is hardware replacement supported on the HE150?
A: The HE150 appliance is a small, tightly integrated form factor so when a component fails in an HE150, the entire node will be replaced, rather than individual components.
Q: How will a cluster of HE150 systems ship?
A: Each cluster will ship together (3 systems) in one outer shipping box. The number of shipments/outer boxes will vary depending on the number of HE150s ordered. Packaging and shipping specifics subject to change.
Q: Can I buy the software from Scale Computing and then buy the hardware separately on my own?
A: No, the solution is delivered as an appliance. In some cases, where very large volumes of appliances are needed, special considerations may apply.
Q: Are there different purchasing or license options for large deployments?
A: Multiple pricing options are available including per appliance, per site subscription, and MSP subscription. Please contact Scale Computing sales for more information.
