Testing Jumbo Frame Support on ESXi

You will need to SSH into the host to perform these commands. This is the basic syntax vmkping -4 -d -I <vmk-number> -s <packet-size> <address> This is an example using vmk3 and vmk4, which we will assume is used for storage. We will use a packet size of 8400 bytes (can’t use 9000 b/c there won’t be enough room to allow for IP overhead) We will assume 192.168.1.10 is the address of the storage interface vmkping -4 -d -I vmk3 -s 8400 192.

To enable SSH on the MBR Align Suse VM, do the following: Open the shell Enter the below command: sudo /etc/rc.d/./sshd start Thats it; done.

Leveraging PowerShell

While I am no seasoned veteran with PowerShell, I have been using it heavily for the past 6 months or so to help automate tasks and increase the speed of my system management workflow. I have recently noticed that not many admins that I have been talking to, in and out of my place of work, are really leveraging what it has to offer. I realized that looking at an example .
