HPE GreenLake for Aruba

HPE GreenLake for Aruba Networking offers an experience leveraging the breadth of HPE Aruba solutions with a flexible way to consume network infrastructure via monthly subscription versus an up-front capital expenditure.

HPE GreenLake for Aruba networking solutions are enabled using modular “Service Packs”. Each Service Pack consists of the required Aruba hardware (“Systems”), software, and service components for the specific use case. Service Packs are delivered as a monthly subscription invoiced in advance and can include options for customers to flex their subscription to Service Pack quantities up or down as their needs change.

Where available, a service pack is listed for each product in the reference architecture tables.

Small Campus

The small campus typically supports up to 5000 users with 2-3 devices per user. The network can be a single building, several floors in a larger building, or a group of small buildings located near one another.

The illustration below depicts a small campus consisting of three IDFs in a single location connected to a VSX collapsed core.

Example Design

The example small campus design includes one combined server room/MDF, and three intermediate IDFs that connect to the MDF using multimode fiber. This small campus reference design supports 750 employees and requires 75 APs to provide 2.4 GHz and 5 GHz coverage.

Building characteristics:

  • 3 floors, 75,000 square feet total size
  • 10 wiring closets (IDFs)
  • 750 employees with up to 2500 concurrent IPv4 clients
  • 75 APs
  • 1 combined server room/MDF

Example Bill-of-Materials

The example small campus bill-of-materials includes redundancy and bandwidth suitable for a highly reliable LAN and WLAN for a US based, small campus.

Medium Campus

The medium campus architecture is targeted for organizations supporting 5,000–15,000 users with multiple devices per user. The network can be a group of buildings located near one another, one large building, or several large or high-density floors in a building. This architecture uses access aggregation switches to consolidate traffic onto higher bandwidth uplinks toward the core and to provide layer 3 services to the access layer.

The illustration below depicts a medium campus consisting of six IDFs connecting to two, VSX access aggregation points that are further connected to a VSX core with directly connected gateways.

Example Design

The example medium campus design includes a VSX redundant core with directly connected gateway cluster and WAN services. Each floor includes two IDFs that connect to the MDF. This medium campus reference design supports 5,000 employees and requires 500 APs to provide full 2.4 GHz and 5 GHz coverage.

Campus characteristics:

  • 3 buildings of 5 floors each and 500,000 square feet total size
  • 2 IDFs per floor
  • 1 aggregation point per building
  • 5,000 employees with up to 18,000 concurrent IPv4 clients
  • 500 APs
  • 2 gateways
  • 1 MDF/computer room

Example Bill-of-Materials

Large Campus

The large campus architecture is targeted for organizations supporting more than 15,000 users with multiple devices per user. The network would typically be a group of large buildings located near one another. This architecture uses a standalone, layer 3 core and services aggregation points connecting to gateways and WAN services.

The illustration below depicts a large campus comprising six IDFs connecting to two access aggregation points that are further connected to a standalone, layer 3-only core with gateways connected to a services aggregation VSX pair.

Example Design

The example large campus design includes a standalone, layer 3 redundant core and services aggregation points for WLAN and WAN. Each floor includes two IDFs that connect to the MDF. This large campus reference design supports 15,000 employees and requires 1500 APs to provide full 2.4 GHz and 5 GHz coverage.

Building characteristics:

  • 10 buildings of 3 floors each and 1.8 million square feet total size
  • 2 IDFs per floor
  • 1 aggregation point per building
  • 15,000 employees with up to 50,000 concurrent IPv4 clients
  • 1,500 APs
  • 4 gateways
  • 1 MDF/on-prem data center
