It's a little like MTV, but without the Scantily Clad ladies…. Maybe it's something VMware could implement?

Our new video KB articles have been received so well by our customers that we have created a new blog just for video content.  The videos are great for how-to types of topics, or for doing white-board chats. Some folks are just happier having something shown to them rather than having to read through pages of steps.

Reading Time: 1 minute

Have you ever been looking into an issue in vCenter only to find that the time the issue happened has just dropped off of the bottom of the Tasks or Events lists? Well that's happened to me a few times.

VMware Hot-Add Memory/CPU Support

Reading Time: 2 minutes

I've been asked to take a look into the Hot-Add Memory and CPU features which are available with vSphere 4. The concept seems pretty useful and straight forward, but what isn't is the list of Operating Systems that support these features. There doesn't seem to be a definitive list. Either that, or I should have gone to Specsavers?

I've had a look around and I can find two KB articles from VMware: Here, and Here which talk about using Hot-Add on Linux OS's. Another VMware document focused on Microsoft: VMware Guest/Host OS Compatibility Guide There is Jason Boche's great article which he researched and tested himself, And Daniel Eason's summary on Hot-Add.

From these different articles I have taken all of the information and produced the following table which in theory should be all of the OS's which support VMware Hot-Add Memory/CPU.

VMware Certifies First 2nd Gen CNAs on vSphere 4

Reading Time: 1 minute

Yesterday, QLogic announced that its 2nd Generation, Single Chip, 8100 Series 10Gb Converged Network Adapters are now certified by VMware for ESX/ESXi 4.0. This is key because a number of end users have been waiting for VMware to announce certification for 2nd Generation CNAs since QLogic announced the industry’s first 2nd Gen CNAs in March 2009 with support for only Windows/Linux.  EMC, IBM, and NetApp are already supporting the 8100 Series CNAs today. The combination of QLogic second generation CNAs with VMware vSphere 4 enables customers to attain a higher degree of data center efficiency — an Intelligent Converged Data Center.

The 8100 Series 2nd Gen CNAs are the first 2nd Gen CNAs to be listed on the vSphere 4 HCL. This is key because the 2nd Gen CNAs (in comparison to currently shipping 1st Gen CNAs in the market) offer:

  • 150% higher FCoE performance
  • 1/3 the power consumption
  • Standard PCI Express form factor which enables the adapter to be deployed in any leading rack/tower servers with PCIe x8 or larger slot. Current Gen 1 CNAs are compatible only with a limited set of server models due to its large size.
  • Compatible with the latest released standards for FCoE

Below is the URL with more details on the new certification.
