BRRABill's Field Report With XenServer
-
-
-
I was not able to adjust memory before. Now after XenTools I can. (You can also see memory usage which is nice.)

Not to side track this thread (apologies to @BRRABill ), what is the "hyperconverged" equivalent in the XenServer world?
To all you XS experts, what is the "hyperconverged" equivalent in the XenServer world?
Similar to Starwind in the Windows world
XenServer is natively that in the Xen world. Nothing additional needed.
If you had 2, 3 or more XS bare metal installs with local drives, how do you "hyperconverge" all the local disks?
Are you saying with XS the "hyperconvergence" just auto-magically happens?
Of course not, but it doesn't for any platform. If you're setting up a greenfield situation, then you design it from the ground up with XS with single shared storage.
Let's try this again:
In Windows, you can take multiple boxes, add Starwind or Datacore = hyperconverged using local storage (no SAN needed).
How do you do the same thing with XS?
This can do HC for XenServer:

If you REALLY REALLY WANT a gui to get HA setup and running on XenServer, maybe give HA-Lizard a look. Haven't used it myself yet (single host), but I've heard it talked about enough to remember it.... the name is kinda memorable.

It's something I want to configure as well, 2 new host, and then download the HA-Lizard client to both, supposedly it handles the entire configuration from what @halizard said in a previous post.

XS (and XO) show the provisioned size of the virtual disk. Is there a way to show how much space it is actually taking up?
(For example in Hyper-V you could just look at the size of the VHD.)

Same, you either look at the storage device and query it and/or you look at the size of the filesystem image file.
-
Yep there is.
Go to the Dashboard firstFrom the dashboard find the Storage Repository (SR)
Click on it.
Now scroll down a little and you'll see your VHDs
-
I fumbled around for about 5 mins before I bumped my way into this.

Is that functionality available in XC or XO?
In Hyper-V you can right click the storage and it tells you provisioned size and size on disk.
-
But that doesn't tell you virtual drive by virtual drive. Only the main XS drive. (Which you can also see in XC.)

I guess in reality it doesn't matter. You'd be managing the drive sizes in each VM, so it would never be an issue.
I just like to know hey ... this virtual disk is only 10% full without going into the VM itself to check. Pretty easy to do in Hyper-V. I figured it was in XC/XO as well, but I was just missing it.

Aww.. OK I gotcha now..
i thought there was a place to see the assigned space vs the used space - can't see to find it right now.. of course I'm guessing the VDH doesn't shrink when you delete things.. so it will only show the max size it ever was.I thought you only wanted to see how large an assigned VHD was - not the actual internal usage inside the VHD... but I understand now.
-
Also - @BRRABill the ability of Hyper-V Manager to show you the used storage space might only apply to Windows based VMs. That seems pretty likely.

I guess my thinking was that if you overprovisioned a bit, and one of your servers was going nuts, it would be nice to easily see which one it was.
But there should be checks on the individual servers to prevent that from happening.
I am assuming it can be done directly in the XS file system. Was just wondering if it was in XS/XO somewhere.
-
and now I'm back to not following.
-
-
here is one of my 2012R2 servers on ESXi - from here I can't tell how full the VHDs are, only the assigned size.
I might see something different if I thin provisioned those machines, but back then I never did that, so i can't show you what that looks like.
I'm guessing the insite you have to Windows VHDs is the nature that it's Windows on Windows, but if it was a Linux VM, I'm guessing you wouldn't get that information.
