Overview

Overview

Cisco HyperFlex C225 M6 node is a one-rack unit node that can be used standalone, or as part of the Cisco HyperFlex (HX) System, which unifies computing, networking, management, virtualization, and storage access into a single integrated architecture. Cisco HX also enables end-to-end server visibility, management, and control in both bare metal and virtualized environments.

Cisco HyperFlex C225 M6 Server is orderable in two versions:

Following PCIe Riser combinations are available:

  • One half-height riser card in PCIe Riser 1

  • Three half-height riser cards in PCIe Riser 1, 2, 3

  • Two full-height riser cards Riser 1 and 3

  • Riser 1—Supports Riser1. Supports single x16 PCIe supporting full height 3/4 length cards in 2 riser configuration (or) Half-height 3/4-length cards in 3 riser configuration and NC-SI from Pilot4.

  • Riser 2—Supports Riser 1. Supports single x16 PCIe supporting only Half-height 3/4-length cards in 3-riser configuration.
