How to delete a Hyper-V converged switch with System Center Virtual Machine Manager Update 5

With System Center Virtual Machine Manager Update Rollup 5 there came some real cool features. One of my favorit is to deleted and manage Windows Server Hyper-V converged switch or how it is called in VMM standards switch.

Before you can see and work with the VM Switch your VMM environment musst be on Update Rollup 5 and VMM need a network connect to the Hyper-V Host for the whole time. So it might be neccessary to connect one NIC of the host to you management network.

First put the Mode in Maintance Mode

The easiest way to delete the converged switch is to open the Hyper-V Host properties.

VMMSW02

Go to Virtual Switches

VMMSW03

 

 

 

Now select the switch you want to delete and press delete

If all went well, the task in VMM should be green and your vNIC on the host should be removed.

Microsoft recently published a new ebook about Deploying Hyper-V with Software-Defined Storage & Networking. You can find it here.

Error /Faile Hyper-V Host has an unsupported VMM Agent installed

When you update your System Center Virtual Machine Environment, you maybe face the issue that your Agent version is outdated and you are not able to update it.

VMM01

The easiest way is to logon to the host and uninstall the old agent.

VMM02

After you uninstalled it, run the task in VMM again.

VMM03

 

Afterwards it should be fine.

 

Error “Could not udpate managed code add-in pipeline” when starting system center virtual machine manager

Some of you maybe face the issue below when installing the VMM management console on a client.

VMM-Log-Error01

The reason for that issue is, that you user has no read/write permission on the folder.

First step to fix the issue navigate to the folder. In my case C:\Program Files\Microsoft System Center 2012 R2\Virtual Machine Manager\bin but it depends on where you installed the VMM.

VMM-Log-Error02

Than you need to change the permission to full controll for your your user or user group (I use my VMM Admins Group). That fixes the issue.

How to setup Azure Backup with Synology Storage

Hello everybody,

today I want to show you how to setup a disk to cloud backup with the new cloud backup feature from synology storage. In my environment I use Azure as backup target.

Why do I use Azure?

I backup some of my important VMs to Azure as desaster recovery. So if my local systems fail I fire up the VMs in Azure.

 

1. You need to create a new Azure Storage were you store your data. From a security standpoint I would not suggest to use a storage shared with other Azure services you have.

SY-AB-00

 

 

2. After you created one you need to create a new management access key. We will need it later.

SY-AB-000SY-AB-0000

3. Now the needed preparations on Azure are done. Next Logon to your Synology and select the Backup & Replication Plugin.

SY-AB-01

4. Now you click create and select the backup typ you want.

File Backup – You can select Files and Folder you want to backup.

LUN Backup – Backups a complette LUN on Synology LUN on Azure

SY-AB-02

 

5. Now you select “Public Cloud Backup Destination”

SY-AB-03

6.  Now you select Backup to Azure

SY-AB-04

7. Now you enter your Azure Storage account data and create a new storage container

SY-AB-05

8. Now enter your container name you want to use

SY-AB-06

 

9. When everything went well it should look like on the picture below

SY-AB-07

 

 

10. In the next step you need to select the volume and share or LUN you want to backup

SY-AB-08

 

 

11. Here you can also select applications to backup. I won’t do that in my szenario.

SY-AB-09

 

 

12. In the last step you need to do transfer, backup and shedule settings.

Synology configuration for max. IOPS with Hyper-V

Hello everybody,

as most of you know I’m using a Synology DS1813+ as storage for my testlab. Last week I took some time to change my configuration to improve the IOPS for my Hyper-V Systems.

My old configuration with RAID 10 and Block based iSCSI LUNs only brought about 6000 IOPS, so I needed to improve to get more VMs up.

 

Let us start with the Hardwareconfiguration. I’m using a DS1813+ with 8 Disk splitted as followed.

Disktyp Count Capacity HD Vendor & Typ Disk Role
SSD 2 120 GB Kingston SV300S37A120G Cache
HDD SATA 7.200 RPM 6 1000 TB 2x Seagate ST1000DM003-1ER162
3x Seagate ST1000DM003-1CH162
1x Seagate ST31000524AS
Storage

I connected three 1 Gbit/s ports in LACP to my SAN network. So there should be enough bandwidth.

 

My disk are configured as followed:

The SSDs are configured as Cache Volume for our later Hyper-V VM Volume. When you configure the SSC Chache choose “Read-Write”.

SY-PI-0000

 

Now back to the harddrives. You should configure RAID 10 for the disks. You can use RAID 5 too if you need the capacity but you will lose at least 1/3 of the final performance.

SY-PI-0001

 

 

Now you need to create the volume for you VMs. Here comes the point were I lose some performance because I need to create milti volumes on one RAID. For more performance you should choose single volume on RAID but you cannot use the disk any longer for more volumes.

SY-PI-0002

 

The volume must be configured with LUN allocation unit size 4KB for Windows ODX.

SY-PI-0003

 

Now you create the iSCSI Volume and Target. Here you choose regular files and advanced LUN features. If do not use thin provisioning, you will get some more IOPS too but that does not matter.

SY-PI-0004

SY-PI-0005

 

So that’s all you need to do on the storage. Next you need fomat the drive. Here I would suggest to format the driver with NTFS and 4KB unit size.

SY-PI-0006

 

 

As a resulte I got a max. from nearly 12.000 IOPS out of my Synology DS1813+ :)  Not bad for are SOHO Diskarray ;)
