Support for Intel Coleto and Intel Lewisburg SSL chip-based platforms

September 27, 2025
Contributed by: 
C S

The following appliances ship with Intel Coleto chips:

  • MPX 5900
  • MPX/SDX 8900
  • MPX/SDX 15000
  • MPX/SDX 15000-50G
  • MPX/SDX 26000
  • MPX/SDX 26000-50S
  • MPX/SDX 26000-100G

The following appliance ships with Intel Lewisburg chips:

  • MPX/SDX 9100
  • MPX/SDX 16000

Use the ‘show hardware’ command to identify whether your appliance has Coleto (COL) or Lewisburg (LBG) chips.

Limitations

The following ciphers, protocols, and features are not supported:

  • DH 512 cipher
  • SSLv3 protocol
  • Azure Key Vault
  • GnuTLS
  • ECDSA certificates with ECC curves P_224 and P521
  • DNSSEC offload

Note

Support for the Thales Luna Network hardware security module (HSM) is available in release 13.1 build 33.x and later.

View the software-based SSL chip utilization on NetScaler MPX and SDX platforms

From release 13.1 build 21.x, counters are added to view more details about the software-based SSL chip utilization on the following platforms:

  • MPX and SDX platforms that ship with Intel Coleto chips.
  • MPX platforms that ship with Intel Lewisburg chips.

Note

This feature is not supported on the following platforms:

  • SDX 9100
  • MPX/SDX 16000

At the command prompt, type:

> stat ssl

Notes

  • Admin partition is supported, but the utilization for all partitions is shown in the default partition. On non-default partitions, these values display as 0.
  • In a cluster setup, the CLIP address displays the average utilization for all the nodes in the cluster. For node-specific utilization, run the command on the CLI of each node. This data might be incorrect for an SDX platform if the nodes of the cluster are hosted on the same hardware.
  • For VPX instances on the SDX platform, the utilization of each VPX instance is displayed.
