Hi.
We have implemented Private Cloud based on System Center, Hyper-V, vmware on Dell Server equipment. We've implemented Azurepack (Vm cloud atm) and the next step would be daas (fault tolerant mssql, mysql). My superiours tasked me to deploy 2 separate infrastructure configuration in order to find best (in term of overal perfomance) solution.
1st - VM1, VM2, SQL2014 in always on mode, one big Lun on which vhdx's from always on group reside, OS and SQL on a single vhdx = total 2 vhdx (governor is on in azurepack)
2nd - VM3, VM4, SQL2014 in always on mode, boot vhdx disks reside on a separate Lun, data (sql, logs etc) disks presented to vms via virtual FC adapters.(governor is on in azurepack)
Also i need to stress test this two configurations and confirm that а) governor actually works b) receive general io perfomance result on both configurations.
my questions:
1. in your opinion what configuration \ setup is the best solution for hosting tenants database? Our proposed configs is okay?
2. Testing io SQL. I've done some research and planning to use sqlio utility. Could you please share your expirience using this tool ? Anything i should be care of ? It would worth mentioning that tenants (our internal users, resourse consumers) failed to provide me any metrics for governor, so i've no clue what to input there ).
