Hi, there my problem
Vcenter 4.1 on Vm 2vcup and 4gb ram
3 ESX 4.0 update 1 host , dual xeon 5550 with 196 gb of ram
running 126 total vm
Host using 40% copu and 75% memory
connected to san using 2 fc hba per host
1 standalone test esx host 4.0 update 1 running no vm
dual xeon 5550 with 8 gb of ram.
connected to san using single fc hba
San it a netapp
using 10 lun on same raid array
8 datastore running production vm
2 datastore for test purpose
Windows 2008 r2 standard vm on VMSAN08SFS datastore
16 gb space
Windows 2008 r2 standard vm on TESTDATASTORE1 datastore
16 gb space
Test esx host is removed from vcenter
I deploy Windows 2008 r2 standard vm on VMSAN08SFS to datastore VMSAN01SFS , take 51 min
I deploy Windows 2008 r2 standard vm on VMSAN08SFS to datastore VMSAN04SFS , take 52 min
I deploy Windows 2008 r2 standard vm on VMSAN08SFS to datastore VMSAN06SFS , take 50 min
Test esx host connected to vcenter, test datastore zoned only to test esx host
I deploy Windows 2008 r2 standard vm on TESTDATASTORE1 to datastore TESTDATASTORE2 , take 15 min
test esx host removed from the vcenter, test datastore zoned only to production cluster host
I deploy Windows 2008 r2 standard vm on TESTDATASTORE1 to datastore TESTDATASTORE2 , take 53 min
using the same lun and san.
Vm deployment and cloning is very slow using the production cluster host
Vm deployment and cloning is fast using the test esx host.
Production esx host have workload that affect the vm deployment and cloning performance
since my host are only utilizing 40% cpu and 75 % memory then my hba are producing only 20-30 mb disk utilization
we are looking for a setting that can free enough resources to speed up our vm deploy.
