To enhance the performance of Xenserver running 5.6SP2 on HPDL380 G6 with local storage
Problem : Performance of server is very low and taking huge time for creation of VM’s in Xenserver.
The configuration of the HP DL380G6 with 1.6TB local storage with EXT file system, 96GB RAM and Hexacore processor
Workaround : For this kind of issue we need to enable the Array Acceleration ratio in the Array configuration.
By default the array ratio will be 100% read, this has to be modified to 75% write and 25% read.
It is recommended to add BBWC with 512 MB for optimal performance.
Before enabling the VM creation was taking 4 hours 45 minutes
After applying this settings VM creation time reduced to 2 hours 40 minutes.
