Data storage for server VMs - which way?

Post by panto » Fri May 18, 2018 4:50 am

Hi, I’m looking at setting up a couple of servers on my TVS882 and would like to know what options I have available for data storage provision and their pros and cons. If I have a RAID1 SSD pool on which the VMs are stored and I wish to segregate database data, for instance, from the OS should I do that via an additional virtualised drive on the SSD (effectively a file), an iscsi target, a file share (OS may or may not like that and may have speed impacts despite network being virtual only), or some other solution?
Also, does iscsi require a not fully provisioned pool into which you are hard allocating storage space i.e. on the SSD I would soon run out of space by allocating iscsi targets?
I could trial and error this but would prefer to gain knowledge from experienced users. Thanks.

Your question is vague.
What hypervisor are you talking about, Qnap VS or VMware ESXi/Hyper-V running on a separate server?

Sorry, talking completely self contained within Virtualization Station on the NAS.Wondering if it is best to just keep it simple as and extra attached hard drive on the VM and hence file/folder representation on disk or are there advantages to going a different way? I’m guessing an iSCSI target would potentially have the advantage of being able to host the VM on a white box ESXi server in future and still accessing the same storage.
