vSphere HA Isolation Response

As of VMware vCenter 2.5 Update 2 the HA default isolation response changed from “Power Off” to “Leave powered on”. A lot of people liked this new default setting because it would lower the chances of downtime due to a “false positive”. I’ve never been a fan though, I just don’t like using degraded hardware or a degraded ESX host for that matter. Those that did like the change should take notice of the fact that with vSphere comes a new default isolation response: Note that this change is only for new clusters, if you... [Lire la suite]

vSphere, finally available…

When ESX 3.0 was released people were excited about it but it can’t be compared to the buzz that has been created around vSphere. It’s all over the blogosphere, I think every single blog out there published articles  about vSphere weeks even months before it was released . Now the time has finally come, it’s available! Go to the download section of the VMware website to download it. Equally important is the update documentation section. Be sure to download all the documents and start reading! ... [Lire la suite]

Hyper-V R2 Import/Export – Part 1 – The Case for New Import/Export Functionality

This is the first blog entry of a multi-part series of blogs that addresses Import/Export in Windows Server 2008 R2. This blog talks about the scenarios enabled by the changes made to import/export in R2.

Use StorMagic SvSAN if you do not have SAN or NFS

If you don’t have SAN/NAS storage box at home and you did not build an Openfiler NAS with for your lab without aditional physical machine as I did, you might be interested in SvSAN. With SvSAN you will be able to use the internal disks of your ESX Servers for a such an advanced features like vMotion or High Availability. Of course you cannot expect to have the same performance like in real SAN, but for home testing is just fine… So what SvSan is about? First of all it’s free. Not a demo, but you can download a free copy for your... [Lire la suite]

vSphere performance

The last couple of weeks I’ve seen all these performance numbers(most not publicly available though)  of vSphere, one even more impressing than the other. I think every one will agree that the latest one is really impressive, 364.00 IOPS is just insane. There’s no load vSphere can’t handle, when correctly sized of course. But something that even made a bigger impression on me, as a consolidation fanatic, is the following line from the latest performance study:VMware’s new paravirtualized SCSI adapter (pvSCSI) offered 12%...

Will VMware give away VMotion and HA for free?

The virtualization wars heated up again last week when Microsoft announced that the next release of Hyper-V will include Live Migration, its version of VMotion, and High Availability (HA) features for free. Currently, these features are not included for free in VMware’s free edition of ESXi; VMotion is only available in the Advanced and Enterprise versions of vSphere; and HA is included in all but the free and the low-end Essentials edition. This just serves as further proof that Microsoft is desperate to catch up with VMware and win... [Lire la suite]

Memory usage in vCenter Server 4.0

If you are using vCenter Server and plan on upgrading to vSphere you should be aware that vCenter Server 4.0 uses much more memory than vCenter Server 2.5 does. According to the official documentation for both 2.5 and 4.0, the system requirements are very similar: 2.0 GHz or faster Intel or AMD x86 processor. Processor requirements can be more if your database runs on the same hardware. 2 GB RAM. You might need more RAM if your database runs on the same hardware. But VMware has a note in the vSphere documentation that... [Lire la suite]
