Installing Linux Unified Host Utilities and optimizing I/O performance

Linux Unified Host Utilities software includes the sanlun utility, a Lenovo LUN reporting tool that you can use to display information about storage cluster nodes. You must also enable the correct server profile on the Linux host to optimize Lenovo storage performance.

Before you begin

You must have identified the supported Linux Unified Host Utilities version for your configuration. You must also have the tuned package, which is part of your Linux OS distribution and contains the tuned-adm command, which you use to set the server profile on the host.
  1. Download the supported Linux Unified Host Utilities version from the Lenovo Data Center Support site.
