Introduction

This guide provides information on the guidelines and recommendations for networking equipment

and its use with Scale Computing HC3 clusters. This guide covers general concepts rather than specic

conguration options. If you need information on specic conguration information for a switch or other

networking product you can refer to the guides in the Scale Computing Knowledge base or the website

of the manufacturers of the switch or product.

Minimum Switch Attributes

When using switches other than a recommended switch, the following features and attributes should be

strongly considered.

• VLAN support

• Managed switch

• 1 GbE or 10 GbE

• 72/144 mpps for 24/48 port switches respectively

• Allows disabling of spanning tree protocol (STP) on a per port basis

• Supports 802.3x ow control

• (Optional) Stacking or dedicated interconnnect for High Availability (HA)

• (10 GbE Only) SFP+ ports - twinax cables are recommended as they are inexpensive and

compatible

Recommended Switches

These switches are expected to work based on published specications, successful customer

deployments, and/or internal testing. Switches not listed here may work as long as they meet the

stated requirements above in Minimum Switch Attributes. If it is determined that performance

or cluster redundancy issues are due to network latency, dropped packets, or other network issues, a

recommended switch may become the required action from Scale Support.

Known Successful Switches (Untested)

These switches have been seen to be successful in various customer deployments. Switches listed here

have not been tested by Scale and Scale does not offer any guidelines for conguration outside what is

listed in this guide in Spanning Tree (STP) and Flow Control. Switches not listed here may work as

long as they meet the stated requirements above in Minimum Switch Attributes. If it is determined

that performance or cluster redundancy issues are due to network latency, dropped packets, or other

network issues, a recommended switch may become the required action from Scale Support.
