Looking to change the default "Datastore usage on disk" alarm on a per VM basis.
I am basically looking to disable the alarm on individual datastores that are used on single VM's with thick partitions where growth is not a concern. Is this option available, or is there a...

I have storage with ocfs2, for about 4tb. There are some virtual machines in xen. I want to migrate or convert them to vSphere. So that is why i have to use this storage as datatstore, but when i try...

That is impossible.You have to use Xen to export the existing VMs to a temporary storage first - and then re-import them once you have created a regular VMFS datastore.

What is the exact way VMware ESXi works with storage?
I'm trying to figure out how exactly ESXi storage subsystem works. I'll give you an example. The first peak [1] is the result of: vmkfstools -i /vmfs/volumes/RAID0-1/333/333.vmdk...

Re: What is the exact way VMware ESXi works with storage?
Assuming your disk/LUN has a throughput of ~125MB/s, this would explain [1] with read and write combined to ~250MB/s, and it would explain [3] with read-only access.The reason for [2] is due to the way...
View ArticleRe: What is the exact way VMware ESXi works with storage?
But how LUN can have such a cap? Write bandwidth is proportional to the number of disks (2 — 220 MBps, 3 — 330 MBps, etc), but read is limited independently on number of disks.Read bandwidth when using...

I would recommend trying to go for Win 2012R2 as the OS for the StarWind Virtual SAN controller VMs, also try Diskspd instead of ATTO as a benchmarking tool. Another thing you might consider doing is...

It's real time. Looking at the last hour, there were 2 brief spikes up to 1200 IOPS. I haven't deployed any VMs from it for months.

For me to get VVols to work, it wasn't the "short name" that I needed to use, but rather the IP address, i.e.:https://10.201.30.184:8443/vasa/version.xml VVols and policies were working great for...
