Tip #3 – By: Gene Homan When a large volume is in use (like in the case for the GroupWise post office volume) it is highly recommended to disable the Linux OS file system auto check feature that runs on an OS boot up every so many mounts or days for a disk partition.Note: This is accurate for VMWare guests with local VMDK disks on VMWare, but not for SAN attached storage. " entry >Įdit "Optional Kernal Command Line Parameter" line and add " elevator=noop" at end of it SLES11: Section Management tab > Edit "SUSE Linux. You need to set elevator=noop in the SLES OS boot-up.Here are the steps to accomplish this setting within SLES: When you let VMware take care of this, you will see disk speed increases some times up to 30%. Tip #2 – By: Gene Homan If running SLES under VMware ESXi, allow the VMware Hypervisor to take care of the disk IO block request order instead of SLES trying to figure out the optimal block request order.Note: It is accurate for SLES 11, but with SLES 12 we include open-vm-tools which do the same thing as the VMWare tools provided by VMWare, plus the open-vm-tools are installed automatically when you install SLES 12, so the VMWare provided tools are no longer needed. Overall the SLES OS performance and management is improved.
The VMware Hypervisor can issue “Shutdown Guest” and “Restart Guest” commands into the SLES OS gracefully.
- Provides support for guest-bound calls created with the VMware VIX APIĮxample of what can be done with the tools in place:.
- Synchronizes the time in the guest operating system with the time on the host.
- Provides the ability to take quiesced snapshots of the guest OS.
- Inability to copy and paste and drag-and-drop files.
- Installing VMware Tools eliminates or improves these issues:
- Tip #1 – by: Gene Homan If running SLES under VMware, it is highly recommended to install the VMware Tools for Linux so the SLES OS runs super efficient under VMware.
