Operation Jumbo Frames – MTU 9000 for VMware Networking

by

Wanted to make a quick post about enabling Jumbo Frames in my VMware environment! My switches (Cisco SG-200 & SG-500) support Jumbo Frames so I thought why not? It would surely help push more data through the network for faster for VSAN and vMotions. I’ll do some speed tests later to compare!

Hardware Requirements:

Before you start out on this quest ensure your physical switch support jumbo frames. When enabling it on my Cisco switches a switch reboot was required:

1 Cisco SG Series - Jumbo Frames

The next step is to ensure the NICs in your servers support jumbo frames. If they are server NICs then they should. My Dell T620/R520 both have Broadcom NetXtreme 5709 which in fact support Jumbo Frames.

Deploying VMware Update Manager 6.0 Update 2

by

With the release of vSphere 6.0 Update 2 I needed to update my hosts! VMware Update Manager [VUM] makes updating and patching your environment very easy. It can also be used to upgrade VMTools and VMHardware versions on your virtual machines. In this post I will be installing VUM on Windows Server 2012 R2 VM using the SQL Express database and attaching it to my VCSA 6.0 U2 appliance. Once installed then I will use VUM to update my environment!

VUM Getting Started

Requirements:

  • Must have a vCenter.
  • Software: .NET Framework 3.5 needs to be installed on the VUM server. For two install methods click here and here.
  • Hardware: 2 GB of RAM if separated from vCenter. 8 GB of RAM if installed on a Windows vCenter.
  • Storage: VMware recommends at least 120 GB of free space for the patching repository. Sizing Estimator for vSphere Update Manager 6.0.
  • Database:
    • SQL Express: If you have a small environment (VMware says 5 hosts and 50 virtual machines or less) then the embedded SQL Express database is just fine.
    • External: If you have a larger environment then you will want to use a external database. Click here and here to read more about having a external database.
  • For a full of requirements check out the VMware Update Manager 6.0 Update 2 Release Notes.

Deploy and Configure WSUS on Server 2012 R2

by

Windows Server Update Service [WSUS] is a server role that serves as a repository for Microsoft product updates on your network. Instead of every computer on your network downloading updates directly from Microsoft you can deploy a WSUS server so the updates are downloaded once and distributed to your environment from the WSUS server.

In this post I will be deploying WSUS Server 2012 R2 in a domain environment, using the Windows Internal Database (WID), and using Group Policy to have my computers connect to WSUS instead of Microsoft Updates.
