Server 2016 - PerfNet Application Error Event ID 2006

Server 2016 is out and although it's still a baby, I've decided to slowly put it in production as a secondary storage/backup server. I was testing on a Dell PowerEdge T320 server with 10GB & 1GB nics and other than some iscsi configuration, everything else was at default settings on the system. Please note that this is a physical machine and not a VM!

Server 2016 is great and I have to admit, the experience has been really good so far... I'm sharing one of the difficult issues I had

Veeam Backup Warning - SQL VSS Writer is missing: databases will be backed up in crash-consistent state

Problem:


When Veeam backup job is running for a SQL server VM and the "application aware processing" is activated on the job Veeam is not capable of using the VSS Writers to backup the databases. Instead, Veeam will proceed with a full backup. The disadvantage is when you need to restore backups in crash-consistent state, you won't be able to recover just the application items (databases, mailboxes, AD objects, etc...), you'll have to do a full restore or just OS files but no application objects recovers.

Notes:

Veeam even has a KB article for the issue. https://www.veeam.com/kb2095

Most of the time, it looks like it's a database naming issue. If your database names contains spaces in them, Veeam is not able to use the SQL VSS Writers.

I strongly suggest that you go trough that article before trying the solution found here. However, in my case, none of the solutions worked from veeam's article.

Solution:

I had to login to my SQL server and under services, change the "SQL Server VSS Writer" service logon account to a domain user account instead of "Local System" account.

Once you do this, your next backup will be processed properley with the application aware processing.

iSCSI Storage Performance & Benchmarking with IOMeter



This is a storage performance report that I have done on 3 different storage types. I was curious to see the performance difference between different types of iSCSI storage units. I wanted to share the results with others because when I wanted to compare my results with others, I was surprised to see that there are a lot of people discussing about storage technologies and all but no one is actually sharing their benchmarks openly.
Because, a storage benchmark can vary a lot depending on your environment, I am going to list my setup so you can compare these results to your own environment as close as possible.

WDS, PXE Boot, DHCP and VLANs… How to manage?



I’m a big fan of easy deployment, scripting, automating etc… Therefore I love deployment tools. I am constantly using tools like Microsoft System Center, WDS, MDT, etc… Thanks to these kinds of tools, I can be alone and have the workforce of an IT army :)

Windows Server 2012 R2 Boot.wim doesn't load during Boot

I am not sure if this happens under all circumstances but I wasn't able to use the boot.wim file from a Server 2012 R2 setup media. In my WDS server, I added a boot.wim file from the Server 2012 R2 setup ISO as a new Boot Image. I used a vm to boot into the PXE server and try the new boot image but I got the following error;

File: \Windows\System32\winload.exe
Status : 0xc000000f
Info: The selected entry could not be loaded because the application is missing or corrupt.
