How to add ESXi custom drivers using an USB key

15 January 2013
Comments off

Reading Time: 2 minutes As written in the previous post, one common issue with recent servers of new generations is that maybe the NIC drivers are not included in the standard ESXi ISO. An if you use the vendor (or a personal) customized ISO, could be possible that during a patch update or a version upgrade you loose the drivers and the system is no working anymore. In those cases you may have an ESXi that complete his bootstrap, but without any network connectivity is not usable and could be hard to fix the missing drivers because VUM and […]

Reading Time: < 1 minute There could some cases where you may have some Windows (Server) completely isolated from the Internet, for example in some appliances or storage solution. One interesting aspect that learn on Windows products during a DataCore training was that in this case you can have some delay in the user interface, both on the DataCore GUI, but also on the Windows one.

Microsoft Virtual Labs

Reading Time: 5 minutes Some months ago I’ve write about the VMware Hands on Labs and how labs are important for testing and learning about a product (also for other vendor). Events like VMworld, Microsoft TechEd, Dell Storage Forum, HP Discover, … are a good moment to have access at those kind of labs. But of course you can also build your own labs (as described in this post) but this require more effort. A good work-around is use on-line and on-demand lab. For VMware the on-line version is just in beta, but for Microsoft this kind of tools […]

Issue in VM migration: MAC Address may change

Reading Time: 2 minutes Recently I got a strange issue using a cold storage migration usign the Migrate function of vCenter Server. This was the scenario: a Free Hypervisor with some VMs where a full license (Essential Plus) was added and the host was also added to a vCenter Server. For compatibility matrix reason the version 4.1 was used (although the storage can work with vSphere 5.0 but officially was not supported). Also the Free Hypervisor was build with the 4.0 version and upgraded (one year ago) to the 4.1 version. This was the issue: after a cold storage […]

Consideration about storage architectures

30 July 2012
Comments off

Reading Time: 5 minutes Storage is an important part of a virtual infrastructure, but compared with the server part (that provide computational “power”) the different storage vendor’s solutions are not so homogeneous and easy to compare or understand. Of course because there are different positioning but also a lot of different aspects, but in most cases, the most important aspects are also the “hidden” or the less described. What is probably clear is the difference between local storage (DAS) and shared storage (SAN or NAS, but sometimes also some kind of DAS) and why shared storage is so important: […]
