Lumen Private Cloud on VMware Cloud Foundation is a hosted private cloud service that provides a managed infrastructure for Customer’s use. The infrastructure includes use of the physical servers, space and power for the servers, virtualization Software system licenses, network connectivity to layer 2 switches, use of integrated storage services, management and monitoring of the servers and underlying infrastructure hardware virtualization Software packages system, and use of VMware Cloud Director (VCD) interface for automated instance provisioning. Lumen Private Cloud on VMware Cloud Foundation is based on Lumen’s Hybrid Cloud management strategy. For clarity, Lumen Private Cloud on VMware Cloud Foundation uses VMware’s Cloud Foundation Architecture, including Software-Defined Networking and VSAN Storage for a completely integrated Hyper-converged Cloud Infrastructure.
VCD allows the Customer to configure the environment enabled by Lumen Private Cloud on VMware Cloud Foundation.
The primary capabilities of Lumen Private Cloud on VMware Cloud Foundation are:
Optional Add-on Services:
Note: The Service Level Agreement (“SLA”) applicable to this Service is the “Managed Hosting Services” SLA Attachment.
A Lumen Private Cloud on VMware Cloud Foundation Host is a dedicated, physical server as well as licensing, monitoring and management of the VMware Cloud Foundation Software Bundle, including vSphere Enterprise Plus, Software-Defined Data Center Manager, NSX Enterprise, VSAN Advanced and VCenter. Lumen Private Cloud on VMware Cloud Foundation Hosts are built upon the HPE ProLiant or Dell PowerEdge rack mount servers. Traditional server Hosts are available in various configurations.
Lumen Private Cloud on VMware Cloud Foundation Host options are the HPE DL-Gen10 or the Dell PowerEdge R640 with the Intel Scalable Xeon Platinum/Gold/Silver Series CPU Configuration Options. Note that a Minimum of 4 Hosts is required per stack.
|Standard Options||Custom Option|
|Small Configuration||Medium Configuration||Large Configuration||Custom Configuration|
Please note: RAM can be configured in 128 GB Increments. Usable storage can be configured in 2.5 TB or 5 TB increments with a 5 TB minimum per Host.
Each Host is connected to dual homed 10 GigE switches with 4 10 GigE Ports. Two 10 GigE Ports are for VSAN traffic only and two 10 GigE Ports are for Customer traffic and VMware management. There is also a single GigE port connected for HPE Integrated Lights Out (ILO) or Integrated Dell Remote Access Controller (iDRAC) for remote management. Lumen and its vendors do not have access to any customer information or traffic transmitted via the Service.
All capacity storage provided with Lumen Private Cloud on VMware Cloud Foundation is SSD Local Disks that are configured with VMware VSAN as part of the standard service offering. Hosts also include NVMe drives for Storage Caching. The default VSAN configuration is RAID-1 with Dedupe and Compression Enabled. Additional VSAN Storage can be added to a Lumen Private Cloud on VMware Cloud Foundation Host through a change order process, which means a Service Order signed by the Customer. Additional storage must adhere to vendor requirements, including that all VSAN storage has to be symmetrical across all Hosts. For example, if Customer wants to add 2.5 TB of useable storage to one Host, Lumen will require that Customer also purchases the same amount of storage to all Hosts in the stack.
Adding RAM to Lumen Private Cloud on VMware Cloud Foundation Hosts can be done through change order process requiring a new Service Order to be signed. Consistent with storage requirements above, and per vendor requirements, the additional RAM ordered and installed needs to be same amount for each of the Hosts in the stack. For example, if Customer wants to increase a Host by 128 GB of RAM, Lumen will require that Customer increase the RAM on all Hosts in the stack.
Customer has the ability to install any type of Guest Operating Systems (OS) or Virtual Appliance as long as it supports being installed on a VMware Hypervisor Platform and the version of Vsphere implemented. Customer is solely responsible for ensuring that any Guest OS or virtual appliance is and remains compatible with the Lumen Private Cloud on VMware Cloud Foundation infrastructure provided and maintained by Lumen.
Guest OS licenses may be provided by the Customer or Lumen can provide licenses for Window Server or RHEL for a fee.
Lumen is responsible for maintaining and supporting all standard installed VMware software and connectivity to the Lumen Private Cloud on VMware Cloud Foundation Hosts as listed here:

VCD is the interface presented to the Customer. From the VCD login it is Customer’s responsibility to build out their networks, routers and security devices such as Server Load Balancers, Firewalls and VPNs and setting security policies on each device. In addition, the VCD environment is where a Customer will create a Catalog of images, Templates, import open virtual formats (OVFs) and manage Snapshots. All interactions to the backend VCenter, NSX, VSAN, and Vsphere software applications are done through the VCD interface and not directly with the individual VMware software packages. The VMware Cloud Director Tenant Portal API’s are accessible to the customer.
Lumen maintains and monitors all components of the Lumen Private Cloud on VMware Cloud Foundation Service - physical servers, including the repair and replacement of defective or failed hardware and the installation of firmware updates, as needed. Hardware upgrades, such as increasing RAM or increasing Storage, can be performed by Lumen for an additional fee. Lumen may subcontract any hardware support to the manufacturer or equivalent vendor in order to expedite repairs.
Lumen also monitors and maintains all of the VMware Software that is installed as part of the standard Service.
The following diagram identifies the Services and the optional Add-On Services that are available.
Lumen will update Lumen Private Cloud on VMware Cloud Foundation Hosts with all VMware recommended security patches, updates or hot-fixes and will address the overall integrity and performance of servers. Security threats are evaluated, verified and tested before a patch is recommended to customers. Sometimes a reboot is necessary when a patch is distributed and installed, which Lumen will conduct during scheduled Maintenance Windows or in coordination with the Customer.
Customers must approve patches or updates prior to them being applied to their environment; however, Lumen is not responsible for any failure in the service, including SLAs if a Customer does not approve the installation of necessary patches or updates.
Please note that VMware Software Upgrades are not included as part of the standard Service but can be quoted and implemented for an additional fee.
