Xeon E2136Xeon SilverHi,
 I am looking at two separate servers that come with two different CPUs (please see screenshots for details).
 When I compare Average CPU Mark, E-2136 @ 3.3Ghz with 6 cores has 15,338 compared to Xeon Silver @ 1.80GHz with 8 cores that has 10,883. But the price of E-2136 @3.3Ghz  is cheaper than Silver @1.8Ghz. I am going to set up Hyper-V server with two VMs (one VM is domain controller and the other VM is Terminal Server running Quickbooks with 2 users and MS ACCESS database accessed by about 8 users via Remoet Desktop Connection. Btw, MS ACCESS database will be converted to MS SQL database at some point)
   
Here are website links for the screenshots:
https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+Silver+4108+%40+1.80GHz&id=3167
https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E-2136+%40+3.30GHz&id=3363

 When you look at CPUs these days, they have so many varieties and down right confusing.
 Which CPU is better and why?

Thanks.

The 7 Worst Nightmares of a Sysadmin

I have Veeam backup and recovery and was wondering why I received the email message after I added disk space to one of my VM's using VMWARE.  I added 50 GB and then rescanned the drive and increased the drive space.  Does it always delete all restore points when you do this?  I thought I've increased disk space before in VMWARE and did not see this message.

Hello!

I got a big problem with vmware workstation 12.5.9 build-7535481:

In snapshot manager I wanted to delete a snapshot.

A message has occourred that there is not enough disk space to do this.

Now the snapshot is not longer visable in snapshotmanager.

The snapshot is not visible running:
C:\Users\hhussy\Documents\Virtual Machines\MONTEVELO3>"c:\Program Files (x86)\VMware\VMware Workstation"\vmrun listsnapshots montevelo3.vmx
Total snapshots: 0

The snapshot-chain seems to be fully functional, because the virtual machine is running correctly.

Directory listing of the VM:

Is there a way to determine which VMs on a host have a CD drive connected besides going to each VM? A host here will have between 40 and 150 VMs so it's a pain to go to each VM.

My reason for this is that when I do upgrades I need to put the host into maintenance mode and undoubtedly there will be some using a CD drive. This prevents vMotion but I don't know until the VM list shows the VMs left that couldn't be migrated. I then need to go to each one and see if it is due to the CD drive. Once confirmed, I need to disconnect the CD drive to continue.

Have a failing cluster disk with an Exchange 2013 CU16 Std VM on it. Pool will not rebuild on new disk and will only attach if the failing disk is in the array.

Storage was reporting no errors and only found due to failing backups, so backups are not current.

I have decided to install a new Exchange box and attempt to move the mailboxes. Issue is I onlu had access to Exchange 2013 SP1 and CU21 and the failing server is CU16 which is not available.

I do not want to even think about attempt installing CU21 on the failing space. My question is whether it is advisable or is a problem to install CU21 on the new machine and migrate the mailboxes with the version mismatch.

I am stuck, storage will not stay stable for backups, VM moves, or even attempting to copy the vhdx. I know the mailbox moves are high I/O but I don't seem to have a choice to to attempt it.

Will the 16 - 21mismatch be a problem?

Thanks,
Chuck

Greetings,

I'd like an expert to confirm that I am able to reboot a VMware Horizon View vCenter appliance without affecting operations of the four hosts it manages or the 80 or so virtual desktops in use.

I am doing this in an attempt to troubleshoot logging in as root. There are 12 failed login attempts recorded. The password in the company's password safe is not working. I tried 5 or 6 times (a few different passwords after the one in the safe didn't work) and a colleague tried as well, thus getting us to 12 failed attempts. I am following the directions here https://www.sneaku.com/2015/06/12/vrealize-operations-manager-6-0-root-account-locked/ as this vCenter appliance is 6.0. Though not vRealize Operations, I suspect the steps are the same.

Further, I am trying to login as root in order to run a shell so I can check the VMware vCenter workflow manager service and also disk space as a new vm pool I created fails to power on any of the new VMs and gives an error stating a general system error occurred connection refused. Troubleshooting that error led me to the aforementioned service and disk space as possible issues but need a shell to get that info. I am not able to run shell as administrator (receive permission error after successfully logging into the appliance with the administrator account). Then, if it ends up being one of those causing the error, fixing it so I can power on these VMs.

Whew, anyway... thanks.

HI,

I'm upgrading a cluster of hosts to 6.5 and wondering if it would break anything if I rename the cluster to 6.5. At the moment its 5.5?

Its an easy process, just wondering if things like Veeam backup will stop working

Thanks

i have a virtual machine within Azure which serves up a web site.

when i navigate to http://api.website.com it works fine.  i purchased a SSL certificate and it imported into IIS.  i edited the bindings for the cert using the default port of 443.  i added the site's name api.website.com to the bindings.  

when i navigate to https://api.website.com i get a "The connection has timed out" error.

the firewall rules allow 443 (default rule).

what else can i check and/or modify within IIS or the OS?  any help is appreciated.

thanks.

Hello,

I have a question regarding VEEAM Backup. We have many vSphere VMs which have terabytes of data. The typical backup strategy is to backup the VMs to disk and afterwards to tape as I know. We have enough space on the backup server to store the full backups but not for the incremental.

So I want to store the full backups on tape and afterwards delete it from the backup server. But VEEAM can not find the full backup anymore, so it starts a full backup instead of the incremenal. Is there a way to achieve what I want or are there any better strategies?

Any suggestions? Thank you in advance.

Hi,

I have VMWare 5.5 and I have 3 Windows servers. Is possible to create a virtual disk and share it to all 3 servers?

For example I create 100 GB disk and add photos and pdf files. Can I link this disk to 3 different VM servers or  for this case I really need to create a shared folder in a Windows server?

Thanks

Need to rescue 3 VM's running on a Problematic ESXi 5.1 host!

Here are the details of The Problematic Host:

Host = Cisco UCSC-C220-M3SBE Running ESXi 5.1, 1065491

Vcenter = NONE, This is a Standalone Host.  

Storage = Local Host Storage, File System=VMFS 5.58, Size=924.50 GB


VM's = 3 VM's Highly critical production VM's that cannot be shut down at all, Total size of used Space on the local storage is 548.29GB

ISSUE = Long story short, there is no way to fully diagnose the problematic host, and so the objective here is to either, move the VM's off the problematic Host and storage onto another host and storage, or just move the VM's to another Storage Device as quickly and non-disruptively as possible.


Here are my thoughts on this:  



Idea #1 I was thinking I could deploy a Vcenter 5.1 server either appliance or windows.   Then add the problematic host to vcenter.  And then add an NFS datastore and then storage vmotion the VM's across to the NFS Datastore.  


Idea # 2(Possibly Not as time consuming as Idea  #1), some how use something like Veeam or some other 3rd party solution.


Need your thoughts!!


Thanks for the HELP!

Is VM - Revert a Snapshot same as restore point in windows?

I have a vm running 2008 server (not R2) that is a primary domain controller and DNS server.   I have 2 vm's now running server 2016 (server2016-dc1 and server2016-dc2). I would like to make DC1 the primary domain controller the demote the 2008 server to a member server.  After that is done DC2 (2016 server) will become backup DC and DNS.  

Is there a good document that will help me step through this?  Also, do I have run adprep on the 2008 server first?  I read something somewhere that indicated that 2016 does this for you.

Hi,

In Azure I see there is an Azure Automation scheduler job which start and stop all dev vm during business hour. How can I remove a vm from that list or  create an exception? This shutdown and Start all DEV VM at specific hours. IM not talking about the shutdown option in VM properties... this is controlled by an automation scheduler.

Thanks

Setting up a new Hyper V environment replacing SBS 2011
I have the opportunity to do a full setup of Windows 2019 server with Exchange 2019 to replace an aging SBS 2011.
I will need a new hardware platform and look for suggestions on the best practices:
1) Should the host OS be on an SSD rather than SAS 15K ? (it will be on a RAID 1 anyway and the Hyper V VMs will be on a RAID 5 or 10 depending on suggestions))
2) Should Active directory be on a VM or a physical machine ?
3) 2 or 3 VMs planned: 1 for Exchange, one for File and print sharing and may be another one for A/D depending on suggestions to 2)

I installed an nVidia Tesla P4 in our Proliant DL360, running ESXi 6.7, and installed the .VIB for 6.7. No errors during install. nVidia Grid license manager has also been installed with a valid license.

After rebooting the server, ESXi sees the graphics card in ESXi. The Graphics Devices tab shows the correct card:
Screen-Shot-2018-12-31-at-2.12.47-PM.png

But when I get to the step of adding it to a VM, I run into an issue. I go to Edit Settings for the VM then Add Shared PCI Device. It automatically populates the box with NVIDIA GRID vGPU, but in the next field I am required to choose a GPU Profile and no profile is available in the dropdown box.

How do I get the GPU Profiles to show up?

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Dears,
I'm looking to fix a server issue at a client site where the backup server has died and thus is in dire need to be replaced.
The current used configuration is VMWare 5.5 but an upgrade to VMware 6.5 will take place very soon.
The backup server VMWare host had usually the DRP storage attached and the replicas of the servers are stored in it.
The backup server was connected at the Storage with a 1GB link passing through  a Cisco SG500 switch.
There are about 10 Virtual Machines, including highly consuming ones like a SMB server and a SQL server

With the replacement server, I have two issues / Questions :
-  the replacement server has no storage  available locally and I don't see the point in adding it because the Thecus storage has already enough disk space with fast drives. Is it possible to use this disk space to run the servers ? I'm 98% sure but I like the 100% :-)
- The connection between the Thecus storage and the Fujitsu storage would need to be upgraded to 10GB to make sure the response time between the storage and the server is kept  at a correct level. Is it possible to connect the 10GB RJ45 port of the Thecus storage directly to the 10GB RJ45 port of the server to establish a fast connection between both of them ?
- If it's possible, I'd have in mind to put two IP manually on each network cards like 192.168.8.1/24 on the server and 192.168.8.2/24 on the Storage to configure the ISCSI adaptor on the VMWare Host.
- I'm also wondering about the DRP …

How to add disk space to Thick provision eager zeroed in VMware? Right now it is greyed out, I tired to see if I shut down the server if I would be able to do it then and that is also not working.

Just installed a 2019 Standard VM. It was there in Server 2016. Did they finally kill of the Scripts folder under Windows->sysvol->sysvol->domain? The group policy folders are gone too. No sub folders to domain at this point. If that is truely the case where is a good place to put logon scripts now?

Extra avhdx filesHi,
  I have a HyperV  virtual machine that has two disks (P...K1-0.vhdx & P...K1-1.vhdx) - C drive and E drive. Each drive carries three files (vhdx, vhdx.mrt vhdx.rct).
 But then there are extra files of avhdx (4AD ...avhdx & B59...avhdx) seen on the screenshot and I like to get rid of it.
 Here is how they are created.
 I created new virtual machine using first disk - P...K1-0.vhdx. But when I tried to add 2nd disk (P...K1-1.vhdx), I added it to the wrong existing virtual machine (called TS1).
 When I eventually added 2nd disk (P...K1-1.vhdx) to the right virtual machine and started the VM, it complained about "file being currently used ...".
 So I rebooted the hyper-V server and was able to start my virtual machine with P...K1-0.vhdx & P...K1-1.vhdx. But my TS1 VM would not start saying "file being currently used ..." and it was put in "saved state". I deleted "saved state" from TS1 and now TS1 is working now.
 However during this process, two sets of extra avhdx, MRT and RCT  files were created and I like to delete them because they are not used and not intended.
 But I just wanted to check to make sure that I can delete them without casuing problems. Fyi, I have not created any snapshot for any VMs in Hyper-V server.

 Can I just delete them?

I am running a Hyper V cluster with two hyper v hosts and one of the host says Host not responding. We cannot see the GUI when we connected to a monitor, nor we can do a remote desktop connect to the server it simply hangs at creating session while doing RDP. Issue is there are few critical vm's running under it which we cannot take them down or risk loosing them due to some issue in future. Is there a way to get the host GUI back without disturbing the VM's? so I can safely migrate the vm's to another host and perform maintenance once I get access to GUI. As of now I feel its too risky to attempt host migration without knowing the root cause.

I have powershell access to that host and I tried restarting terminal services to attempt successful RDP connection however with no luck too.

Looking forward for experts help to get this resolved

Thanks
