In the case of RDP - what do the system resources utilization look like?

resources utilization on the my PC, hypervisor, or VM?

That would depend, are you RDPing into the hypervisor or VM? in either case the hypervisor could be at fault. I'd start by looking at the hypervisor. I know in VMWare you can see the resource utilization of all on a chart, so you should be able to see everything you need from within the hypervisor I would guess.

I just gave the VM more virtual processor from 1 to 4. It does seem more responsive while RDP. But the progress bar when saving still there. The graph on Performance (Task Manager) does not seem to be indicating anything out of ordinary. The graph goes up and down like a heart beat on cross over ethernet and wobbling on internet.

So when you say saving the file is slow... this is when you are saving the file locally on the server or remotely from a workstation?

2 scenarios. 1st I noticed that opening files, saving, deleting, moving seem laggy. 2nd is when I remote into the VM via RDC it seem very laggy and delay. The mouse seem fine but clicking anything seem delayed. This is how I came to the thought of poor network bandwidth

Could be. Does the image update quickly?

How do I check? It should be within couple of seconds.. or every second.

When a file is written to your vSAN, the process doing the writing most likely won't reply that the process is completed until all nodes in the vSAN report that the file has been written.

If there is a bottleneck on the communication between the vSAN servers, this could introduce your delay.

I believe you said you are using x-over cables between the servers for the vSAN, so you likely don't have a switch related problem there. But you could still have bandwidth/latency issues there.

How to check if the bandwidth is saturated on cross over? It does not seem to use much at all.

Starwind console should have graphs available for all kinds of resources utilisation. Btw, you don't need crossover cable on 1Gbit and faster ethernet cards.

I couldn't find where the graph would be located at. But this is the setting on Synchronization priority

This could be related to the disk performance and not the network performance.

Just because the document is being written to a network share doesn't mean that is the issue.

How is this related to disk performance? Please enlighten me.

@scottalanmiller said:

Before I go digging... what is the storage situation? Local storage?

Not sure what you mean but it is configured with vSAN.

This is a separate thread to a thread on the same server but different problem. http://mangolassi.it/topic/7368/hyper-v-failover-live-migration-failed-error-21502

Currently, everything seems to be working fine... at least on the hypervisor side. The VM server is meant for file server and it need to perform in its top notch performance during business hours. However, the performance is barely acceptable. When saving a blank file (excel) on to the VM it takes couple of seconds with a progress bar. This action should be instant. What can I do to improve the file server performance?

it's a gigabit switch.

So you say you have a Gb switch. Those speeds are pretty terrible for a Gb switch transfer, unless the workstation is only connecting to the switch at 100 Mb.

So now I suggest that you check that all connections are listing themselves as 1 Gb connections and correcting any that are not.

All connections are Gb. All cables are CAT6.

can you paste some screenshots of the error or steps you taken when you try to remote in? The more the better. (please don't post anything security sensitive opened in the background).

#(please don't post anything security sensitive opened in the background). what do u mean ??

This is what I replicated. Are you sure that your user is allowed to be remote in on the machine?
You mentioned that something happened is it possible that whatever happens knock the user rights out.

Can you post (if possible) the remote user rights?

@shybrsky

@brianlittlejohn
I have done this on workstation multiple time and yes it works.
I cannot say the same thing for DC as I have not try it yet.

@shybrsky
Can you paste snapshots of the errors or problems? If you need to past 10 snapshots then do so. What exactly is the "Big issue"?

@Dashrender

I did not replicate file between the two cross-over servers. It is from a server to workstation.
it's a gigabit switch.

@Dashrender
it's a 10 minute transfer. The graph only shows a minute(?). Beside I think it should maxed out anyhow. Also, because I transfer the file across the network it doesn't utilize cross-over network.

@travisdh1
Beside setting static ip address I did not do anything more than that. (aside from starwind vSAN)

@Dashrender
First screenshot 5GB. transfer rate 8MB/s - 12MB/s

Second screenshot 5GB. transfer rate steady 10.5MB/s - 12MB/s

@Dashrender
Yes. that is correct.

@Dashrender
I really do not know what am I looking for. The first three are physical. The last one is VM.

@Dashrender
How do I check that?

@Dashrender

Server(VM server) > Cisco(1GB) > patch panel > my PC
Server has 4 ethernet ports. Port 1 is connected to Cisco switch. Port 3&4 is connected between the 2 failover servers via cross-over cable.

@original_anvil
The issue is resolved. However I am experiencing another "problem". I don't want to call it an issue since it does not prohibit the VM server from functioning, nor Failover to fail. I am using the VM servers as file server and some accounting application. I cannot seem to make the network bandwidth as stable as it is on physical server.
On a test 5GB file transfer between my PC to VM server, the transfer rate fluctuated between 7MB to 11MB. Some time as low as 4MB
On the same test between my PC to physical server, the transfer rate is steady at 11MB.
It is not much but for 70 users it might cause performance issue. Any idea?

@Dashrender

Okay.. that does clear up the confusion on my side. The Live Migration I performed is real Live Migration (I tested it by restart the main server to force VM to shutdown).

1. When I first create the HA VM I did not install any operating system which means there is only HDD/BIOS and probably took up no more than couple MB. It is like a barebone machine with only BIOS. That should explain how I managed to do it with 1GB space.
2. After the Live Migration is correctly configured I tried to install OS but failed and returned with not enough storage error (windows PE error). I thought I messed up something so I start fresh again (remove and delete VM), and this time I attach Windows Server ISO along with the configuration wizard. Which is why it keeps failing because the VM knows it does not have enough resources to properly install anything.
3. How did I get 1GB to begin with? It all started back in Starwind vSAN console. I configured 3 disks (storage1/storage2/witness). Storage1 has 1,000GB. Storage2 has 1GB, Witness has 200GB. The mistakes happens with I attach the drives to the server via iscsi. I must have skipped a step somewhere and thought I already did it thus the iscsi was incorrectly configured.

This is the screenshot of the iscsi drives (before fix) Noticed the Disk 3 with 1GB formated and 1TB unallocated space? That's how I got 1GB but shows 1TB.

This is the screeshot of the iscsi drives (after fixed)

If you need help configure your servers feel free to ask anything. Links belows are what I used for configured the HA servers
