Non-Recommended Switches
These switches have not performed well or have performed inconsistently in the eld in a wide variety
of use cases.
• Cisco Catalyst 3650
• Cisco Catalyst 3750 Family
• HP Procurve 1910
• Home, Workgroup, Departmental, or Unmanaged switches do not have sufcient switching

High Availability (HA)
HC3 nodes come equipped with two Network Interface Cards (NICs) for High Availability (HA). These
NIC ports work in an Active/Passive mode, meaning one NIC will be active and the other NIC will be
inactive and will only become active in the event that the primary NIC becomes unavailable. Scale nodes
will use the NIC that is on the motherboard as the primary NIC if both NICs are working properly.
Active/Passive is the only available mode for Scale Computing node NIC congurations at this time.
Dell Networking Cables
Customers are required to provide all of their own network cables for Dell and HP switch models;
Mellanox cables are included and sold through Scale Computing. Any Dell switches purchased through
Scale Computing will not include cables. Below are recommended cables for the Dell switches that have
performed well in a variety of use cases. Scale Computing recommends using the suggested 10 GbE
cables for a given switch manufacturer as they have been tested in most use cases and will help to ensure
compatibility with 10 GbE Scale Computing nodes.
