Here is the environment;
HP BladeCenter with 10 Blades, one blade has dedicated to 2TB SB40c SATA storage and all these Blades has been installed VMware ESX latest version.
Openfiler vSAN install on the SB40c partnered Blade as a virtual machine. These Blades has two network interfaces and one interface dedicated to iSCSI traffic.
Now the system working fine but it's really slow when I do the file copying operations.
What short of tune up do I need to make ? please advise and thanks a lot !
