| Fabric Management | The Intel® Omni-Path Fabric Suite Fabric Manager (FM) solution can be deployed as either a host-based or an embedded solution for an Omni-Path 1U Switch. The host solution uses the Intel® Omni-Path Fabric stack running on a Linux Server to access and manage the fabric. The host based FM is required for managing large fabrics greater than 100 nodes, as the FM software is able to make use of the large memory resources and high speed processor technology of standard servers. The Managed Switch FM deploys all of the host based FM components in an embedded solution using the Pluggable Q7 Intel® Atom™ processor board. The maximum fabric configuration supported by the Embedded FM is 100 HFI ports involving less than 20 Switch ASICs (1 ASIC per 1U switch). For the small-to-moderate fabrics, the embedded FM provides cost savings in that the fabric is able to utilize an existing resource for the embedded FM purposes. The Unmanaged Switch does not have the Q7 Intel® Atom™ processor and requires either a host-based FM or Managed Switch solution. | |
