What's New

The Linux Host Utilities 7.1 release contains the following new features and enhancements:

  • Linux Host Utilities is now called Linux Unified Host Utilities because it supports NetApp E-Series storage systems running SANtricity as well as AFF, FAS, and ASA systems running ONTAP.

    Note Any mention of Host Utilities or Linux Host Utilities in this document refers to Linux Unified Host Utilities.

  • The following operating systems are now supported:

    • SUSE Linux Enterprise Server 15 series

    • Oracle VM 3.2 series

    • Oracle Linux 6 and 7 series

    • Red Hat Enterprise Linux 6 and 7 series

    • SUSE Linux Enterprise Server 11 SP4

    • KVM and XEN, RHEV 6.4 and 6.5

    • Citrix XenServer

  • On Red Hat Enterprise Linux (RHEL) 6 and RHEL 7 hosts, a tuned package for setting server profiles is now supported. You can use the tuned-adm command to set different profiles, depending on the environment. For example, you can also use the virtual guest profile as a guest virtual machine and you can use the enterprise storage profile for configurations where LUNs from enterprise storage arrays are used. Using these tuned packages can result in improvement in throughput and latency in ONTAP.

  • Adds support for 32GB FC adapters from Broadcom Emulex and Marvell Qlogic.

Note NetApp continues to work with the Host Utilities to add support for features after the initial release. For latest information about the features that are supported and the new features that have been added, see the NetApp Interoperability Matrix Tool.
