Dell Storage Forum 2012 London – Day1

9 January 2012
Comments off

Reading Time: 2 minutesOne of the first big events of this new year will be the Dell Storage Forum (the first Dell’s European storage show) during the second week of January (9-12). This event was partly born from the hashes of C-Drive (Compellent trade show) that was supposed to have its first European incarnation last year but due to the acquisition of Compellent by Dell C-Drive got canceled and Dell Storage Forum was born instead conveying all things storage by Dell in a single storage-focused event.

Veeam Backup & Replication – Understand the backup format

4 January 2012
Comments off

Reading Time: 2 minutesCompared to other backup software, Veeam Backup & Replication has several formats to save and handle the backup files. As you can see in the Advanced Settings for each backup jobs there are different formats (or mode) where the files are saved: Reversed incremental: the last file is a full version and past files are re-calculated as delta files. Incremental: the first file is a full one and on each backup jobs is created a new delta file. Incremental with synthetic full: similar to the previous but a new full file is periodically re-calculated. Incremental with […]

Predictions and forecasts for 2012

31 December 2011
Comments off

Reading Time: 2 minutesI don’t like make predictions, because the future isn’t so clear or simple, and in the IT one year could be lot of time and lot of changes. Also I see a lot of predictions that seems only in a binary state (who is in, who is out)… but the real could be completely different from a simple black and white approach. For example same say that the 2012 will be the year of the VDI (I’ve heard this in the last 3 years), others that will be the big fail of the VDI and […]

Why Dynamic Disks are a bad choice

22 December 2011
Comments off

Reading Time: 3 minutesMicrosoft Windows Dynamic Disks (or Dynamic Volumes) are an abstraction layer (introduced in Windows 2000) over the partitions (similar to the LVM layer on Linux environment) to decoupled the volumes (with their NTFS data) from the disk partitions and have a greater flexibility, like hot-extend a volume by simple add new partitions (but also several other advantages). But in a virtual environment there are other way to handle disk flexibility, like hot-extend a virtual disk at hypervisor level (for VMware this feature was introduced in VI 3.5U2)… so there is no need to use dynamic […]

ESXi – Partitions layout of system disk

20 December 2011
Comments off

Reading Time: 3 minutesIn ESXi the partitions schema is automatically defined by the installation process and there is no way to modify it (you can only choose where install the hypervisor). There is a great post from Rickard Nobel (ESXi 5 partitions) that explain the structure of the partitions, their size and their purpose. But it does not explain how to get this information. To see the partition layout in ESXi 5, the fdisk command will not work on new GTP disk (this type is used for all new disks and for disks that are extended to more […]

Storage Best Practices: Vendor vs. VMware

16 December 2011
Comments off

Reading Time: < 1 minuteA best practice is a method or technique that has consistently shown results superior to those achieved with other means, and that is used as a benchmark. In addition, a “best” practice can evolve to become better as improvements are discovered. But, as well described by Frank Denneman in his post, best practices are never absolute, they depends on your specific case.

ESXi Performance Graphs – VM Power

9 December 2011
Comments off

Reading Time: 2 minutesThere is an performance monitor at VM level that show always a null value: it’s the VM Power Graph. The same monitor at host level show the power usage of the specific host. But by default, the power usage of the VMs are not calculated. To enable this experimental feature you must change an advanced parameter (Power.ChargeVMs) on each host (by default, as show in the picture, is zero… it must be changed to 1):
