Multiple vmkernel ports in the same subnet

VMware support insider has another excellent post. This time covering some of the challenges with multiple vmkernel ports in the same subnet.

Mike does a great job walking you through the difference between ESX and ESXi with multiple vmkernel ports.

(Command line stuff as well)

Troubleshooting Network Teaming Problems in ESX/ESXi

It has been a little while since my last blog. Where has the year gone!

Here is a blog from VMware Support Insider about Troubleshooting Network Teaming.

As Mike Da Costa states "Perhaps one of the most common types of problems we encounter here at VMware Technical Support is relating to loss of network connectivity..."

I would agree its been an area that can be easily misconfigured.

VMware Tech Preview

Cormac Hogan from VMware has a three part Tech Preview series. The series is over at vSphere Blog.

The first part covered Distributed Storage Tech Preview which has a video. Basically what  it does is aggregates the hosts’ local storage and makes a single pool of storage shared across all hosts. Within the blog Cormac has other links highly recommend reading those.

• Massimo Re’Ferre
• Duncan Epping
• Christos Karamanolis

Distributed Storage Tech Preview 

The second part was Virtual Volumes (VVOLs) Tech Preview which also has a video.

"What if the vSphere admin could decide up front what the storage requirements of an application are, and then tell the array to create an appropriate VMDK based on these requirements? Welcome to VVOLs"

Virtual Volumes (VVOLs) Tech Preview 

 Lastly the third posting was Virtual Flash (vFlash) Tech Preview.
"To date, VMware has done very little around flash. We only have the smartd introduced in vSphere 5.1 to monitor Solid State Drives (SSD) attributes and the swap to SSD feature....."

Virtual Flash (vFlash) Tech Preview

 

Migrating virtual machines with Raw Device Mappings (RDMs)

A presentation on migrating virtual machines with RDMs FAQ.

Areas that are covers are;

• Warm migration (vMotion), where the virtual machine state as powered on.
• Cold migration, where the virtual machine state as powered off.
• Storage migration (Storage vMotion), where the virtual machine state as powered on.

vSphere client - Which one to use?

Administrating your vSphere 5.x environment can now be done via a Web Client. So now the question is asked when to use what? As some features can only  be administered via vSphere Web Client.

 The table below details features available in Web Client and Desktop Client and if a feature is not listed then the feature is available in both.

Information from vSphere Blog.

VMFS Locking Uncovered - vSphere Blog

Finally have time to get something on my blog.

Cormac Hogan from VMware has  a very good blog about VMFS. He starts by general overview on VMFS locking. Which over my time in virtualisation is misunderstood more often than not .

 Areas covered:

• Heartbeats

• On-disk Metadata Locks

• Optimistic Locking

• VAAI ATS (Atomic Test & Set)

Stretched Clusters and VMware vCenter, Site Recovery Manager

Been meaning to get this up....better late than never.

Stretched Clusters and VMware vCenter, Site Recovery Manager


"This paper is intended to clarify concepts involved with choosing solutions for vSphere site availability, and to help understand the use cases for availability solutions for the virtualized infrastructure.
Specific guidance is given around the intended use of DR solutions like VMware vCenter Site Recovery Manager and contrasted with the intended use of geographically stretched clusters spanning multiple datacenters.
While both solutions excel at their primary use case, their strengths lie in different areas which are explored within."

Antivirus Practices for VMware View 5

The documents talks about Best Practices for protecting VMware View Desktops from viruses.

http://www.vmware.com/resources/techresources/10258

"This paper focuses on the best practices for protection against viruses in the VMware View™ 5 virtual desktop
environment. Antivirus software is one of the largest segments in today’s computer security market. Nearly
every enterprise deploys antivirus software on every desktop. As services such as security, mobility, access
control, and line-of-business applications are all rolled up into the datacenter or cloud, antivirus practices need
to be rolled up as well."
