Built into the HP Moonshot 1500 Chassis architecture are four separate and independent fabrics that support a range of current and future capabilities:
• Network fabric
• Storage fabric
• Management fabric
• Integrated cluster fabric
Network fabric
The Network fabric provides the primary external communication path for the HP Moonshot 1500 Chassis.
For communication within the chassis, the network switch has four communication channels to each of the 45 servers. Each channel supports a 1-GbE or 10-GbE interface.Each HP Moonshot-45G Switch Module supports 6 channels of 10GbE interface to the HP Moonshot-6SFP network uplink modules located in the rear of the chassis.
Storage fabric
The Storage fabric provides dedicated SAS lanes between server and storage cartridges. We utilize HP Smart Storage firmware found in the ProLiant family of servers to enable multiple core to spindle ratios for specific solutions. A hard drive can be shared among multiple server cartridges to enable low cost boot, logging, or attached to a node to provide storage expansion.
The current HP Moonshot System configuration targets light scale-out applications. To provide the best operating environment for these applications, it includes HP ProLiant Moonshot Servers with a hard disk drive (HDD) as part of the server architecture. Shared storage is not an advantage for these environments. Future releases of the servers thattarget different solutions will take advantage of the storage fabric.
Management fabric
We utilize the Integrated Lights-Out (iLO) application-specific integrated circuit (ASIC) standard in the HP ProLiant family of servers to provide the innovative management features in the HP Moonshot System. To handle the range of extreme low energy processors we provide a device neutral approach to management, which can be easily consumed by data center operators to deploy at scale.
The Management fabric enables management of the HP Moonshot System components as one platform with a dedicated iLO network. Benefits of the management fabric include:
• The iLO Chassis Manager aggregates data to a common set of management interfaces.
• The HP Moonshot 1500 Chassis has a single Ethernet port gateway that is the single point of access for the Moonshot Chassis manager.
• Intelligent Platform Management Interface (IPMI) and Serial Console for each server
• True out-of-band firmware update services
• SL-APM Rack Management spans rack or multiple racks
Integrated Cluster fabric
The Integrated Cluster fabric provides a high-speed interface among future server cartridge technologies that will benefit from high bandwidth node-to-node communication. North, south, east, and west lanes are provided between individual server cartridges.
The current HP ProLiant Moonshot Server targets light scale-out applications. These applications do not benefit from the node-to-node communications, so the Integrated Cluster fabric is not utilized. Future releases of the cartridges that target different workloads that require low latency interconnects will take advantage of the Integrated Cluster fabric.
Moonshot System network configurations
Moonshot System network switches and uplink modules provide resiliency and efficiency when configured as stand-alone or stackable networks. This feature allows you to connect up to nine Moonshot 1500 Chassis and then to your core network, eliminating the need for a top of rack (TOR) switch.
- Dual switches provide traffic isolation or can be stacked
- Rack level stacking simplifies management domain
- Redundant switch configurations provide a more resilient infrastructure
- Layer 2, Layer 3 Routing & QoS, Management (CLI, SNMP, SFLOW).
