Installing an ESXi from a USB device

Reading Time: < 1 minute

You can run the ESXi installer usually from the CD (official or customized), but also from PXE or from USB. The CD installation (still in version 5.5 the ISO fit on a CD) remain the most used option, but in some cases it’s not applicable.

For example recent servers or blade systems lacks of the CD/DVD unit and in this case the only option is use the hardware management interface (like the IOLE for HP or the iDRAC for Dell), or use alternative boot options.

PXE could be valuable in some cases, but require an infrastructure that is not so fast to be deployed. So USB remain the most reasonable option for a quick installation in those cases.

Granular restore of application is usually a complex and long task that may require also good knowledge of the application itself. This because most backup programs just restore the application files and then using specific application procedures you can restore specific objects from those recovered files.

As written in previous posts, Veeam Backup & Replication has different ways to handle object restores: using Application Item Recovery (AIR) or, for some applications, using a specific Veeam Explorer components.

For SQL Server actually there is only the U-AIR option, that is really powerful but require at least the Enterprise edition and a virtual lab setup.

Running Hyper-V in a nested VM

Reading Time: 2 minutes

How you probably know is possible run Hyper-V role (or Hyper-V Server) in a VM using latest version of VMware virtualization products (vSphere and Workstation) because they also can “emulate” the hardware instructions (AMD-V or Intel-VT) needed of hypervisors like Microsoft Hyper-V (but also, for example, Citix XenServer).

More complicated if you was to run Hyper-V in a nested VM inside Hyper-V (or some other virtualization platform that lacks of this “emulation” feature).

VMware Single Sign On is a new VMware vCenter Server components, introduced for the first time in vSphere 5.1, that manage the authentication across different VMware components both for services and users.

Issue in VMware vMotion that stop at 14%

Reading Time: 2 minutes

Some weeks ago I’ve got an issue in a VMware vSphere 5.1 environment with vMotion that stop each operation at 14% with some strange errors. Also there were several VMware KB articles related to this issues, with different reasons.

The error message was simple: Timed out waiting for migration start request. So the closest KB article was: vMotion fails at 14% with the error: Timed out waiting for migration start request (2068817).

But none of the possible solutions were applicable to my case.

PernixData FVP is a Flash Hypervisor software aggregates server flash across a virtualized data center, creating a scale-out data tier for accelerating reads and writes to primary storage in a simple and powerful way. Was one of first (probably the first) to implement a fault-tolerant write back acceleration.

In the previous posts I’ve described the installation and the configuration procedures of FVP 1.5 on vSphere 5.5, now it’s the turn of the final considerations and comments.
