Reading Time: 2 minutes In the previous post we have described how the command line of a Dell PowerVault storage allows several more operations compare the graphical interface. For example, the disk initialization is just one of the several troubleshooting cases where it becomes mandatory to rely on the command line (or on technical support). Another case is where the RAID of a disks group go into the “corrupted” state: at that point, again, there is no simple solution because you have limited options in the graphical interface. Again, the solution is switch to the command line and use the […]

Reading Time: 3 minutes One of the advantages of Dell PowerVault storage, with the MDxxx series, is that they use disks with identical bays of the server version (obviously depending on the generation, there will bays like the G9 servers or  bays with the same G10, G11, G12 servers form factor). In addition, disks are theoretically interchangeable because are the same models (almost from Seagate vendor, ad least for spinning disks). However, in practice, this was true with MD30xx models and derivatives, but with the recent series (MD32xx or MD36xx), there are some limitation based on the firmware version […]

Reading Time: 5 minutes The upgrade path from Veeam Backup & Replication 6.x to the new version 7 is almost simple and fast: basically you have to upgrade first the Backup Enterprise Manager and then the Backup & Replication part, and finally apply the patch to bring it at the Backup & Replication 7.0 R2 release. The entire upgrade procedure is almost fast and usually can take around 30 min for a simple install with only one single system. Of course before doing the upgrade you need to verify the license file (you need a new one for version […]

Reading Time: 5 minutes As written in a previous post, with the introduction of vSphere 5.0 in addition to the installable version of vCenter Server (which still requires a Windows operating system), there is also a Virtual Appliance version (called VMware vCenter Server Virtual Appliance). VMware vCenter Server Virtual Appliance (vCSA) is a VMware’s official VA that can be used as an alternative way to implement a full vCenter Server, instead to install on a Windows Server (that must be deployed first). Unlike the installable version, it does not require a Windows Server license and instance, but is rather […]

Reading Time: < 1 minute VMware has recently released a new new exam to qualify candidates for the VMware Certified Professional 5 – Data Center Virtualization (VCP5-DCV) Certification. This new exam (exam code VCP550) is based on vSphere v5.5, where the existing exam (exam code VCP510) is based on vSphere 5.0/5.1. Passing either of these exams will earn VCP5-DCV certification. Note that does not change the course requirement (for more information see the official certification page) and that now also for VCP exam you need to request an authorization. Is a change in the common approach of have certification based only on […]

Reading Time: 3 minutes After updating the vCenter Server part to version 5.5, you can focus on the host part. The update of the ESXi host can be completed, as usual, in several ways: Manual update with the installation CD of ESXi (by selecting upgrade and keep VMFS datastore) Manual update using the CLI Automatic updating via vSphere Update Manager (VUM) There are other ways, all discussed in the VMware KB 2058352 (Methods for upgrading to ESXi 5.5).

Reading Time: 5 minutes The VMware vCenter upgrade has some possible issue, considering also that the SSO part is changed from the one implemented in vSphere 5.1. VMware has released the vSphere 5.5b (specifically for the vCenter Server application, both installable and vCSA editions) just before the Christmas holiday. Mostly another bunch of fixes around vCenter Single Sign-On functionality and upgrade errors, so be sure to use this one for the upgrade to reduce the possible issues. Note that most of the issues are related to the vCenter components:

Reading Time: 4 minutes The procedure for upgrade to VMware vSphere 5.1 is quite similar to the upgrade path to vSphere 5.1 (and almost similar also to the upgrade path to vSphere 5.0) and is well described in the specific guide (vSphere Upgrade Guide). And first to all, you have to analyze the pro and the cons of a product upgrade, for more information see also: VMware vSphere 5.5 – Upgrade or not upgrade? You have also to consider (particularly for small enviroment) if apply an upgrade or rebuild. Anyway, some points are quite common for each major vSphere […]

Reading Time: 2 minutes I’m really honored to have been invited to as a delegate for third edition of Virtualization Field Day (#VFD3) event, scheduled in March 5-7, 2014 in California (Silicon Valley). Virtualization Field Day is one type of the Technical Field Day events, organized by Stephen Foskett and his team, with the purpose of bring together innovative IT product vendors and independent thought leaders to share information and opinions in a presentation and discussion format. Virtualization Field Day (VFD) focuses on server and desktop virtualization and management technologies and will be really interesting be part of this event […]

Reading Time: 4 minutes In the previous post we have talk about the VMware Horizon View Event database and how purge the old data in order to free some space. You can have similar issue also with the VMware vCenter Server database, considering that it can continuous grow due to the statistics and also due to the events/tasks. In really small system a simple solution could be re-install a fresh version of vCenter Server (maybe during an upgrade) and re-create all the configuration stored only in the vCenter Server database. But in several cases this approach is not realistic. […]

Reading Time: 3 minutes In an installation of VMware Horizon View one requirement is the VMware Composer database to keep track of the various pools with linked clones. But this is the only mandatory DB (if you have linked clones), because for the various View Connection Servers there isn’t any strictly database strictly requirement, since they exchange and share data via a specific data structure based on Active Directory Lightweight Mode (actually an LDAP tree replicated between each replication server). But in real scenario, it becomes useful, from the management point of view, set up a shared database for […]

Reading Time: 4 minutes After the recent announce of v3.8 of NAKIVO Backup & Replication, now it’s the turn of v3.9 that introduce Multi-Tenancy, Self-Service, and Dynamic License Allocation features. New features enable managed services, cloud, and hosting providers to introduce VM Backup-as-a-Service (BaaS), Replication-as-a-Service (RaaS), and Disaster-Recovery-as-a-Service (DRaaS) to their clients, while enterprises can easily manage VMware ESXi backup, replication, and recovery for multiple sites from a single pane of glass. With the extended products support introduced in v3.8, that include VMware vSphere 5.5, Microsoft Windows 8.1 and also Microsoft Windows Server 2012 R2, this solution is become […]

Reading Time: 3 minutes Veeam Certified Engineer (VMCE) certification is documented proof that an engineer possesses the necessary level of expertise to correctly architect, implement and configure Veeam Software Solutions. This certification is a great investment for an IT professional looking to increase productivity, reduce operating costs, propel personal career advancement and achieve industry recognition. It’s a new certification announced by Veeam some month ago in order to bring a technical certification level in the existing partner’s related certifications (sales and technical pre-sales), similar at the (initial) certifications in the VMware partners program. Note that each VMCE is related […]
