What's New in Linux Host Utilities 7.1

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.

  • The following operating systems are supported:

    • Citrix XenServer

    • KVM and XEN, RHEV 6.5 and 6.4

    • Oracle VM 3.2 series

    • Oracle Linux 7 and 6 series

    • RHEL 7 and 6 series

    • SUSE Linux Enterprise Server 15 series

    • SUSE Linux Enterprise Server 11 SP4

  • On RHEL 6 and 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 use the virtual guest profile as a guest virtual machine and the enterprise storage profile for configurations when LUNs from enterprise storage arrays are used. Using these tuned packages can result in improvement in throughput and latency in ONTAP.

  • Linux Host Utilities 7.1 adds support for 32GB FC adapters from Broadcom Emulex and Marvell Qlogic.

Note NetApp continues to work with the Linux 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 Interoperability Matrix Tool.
