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 the View Events. There are a lot of resources that help in this database setup and configuration (for example, Microsoft SQL Server, there’s this post), but the procedure is not particularly complicated (you need just some attentions on the ports, on the firewall rules and on the authentication type). DBMSs supported are SQL Server (SQL Express can also work) or Oracle.

The possible problem in using SQL Express for the View Event is related to the database file size limit, considering that there isn’t a simple way to handle the data retention.

nakivo-logoAfter 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 more and more complete and competitive, considering also the price really aggressive, the low resource consumption (requires just 2 CPUs and 2 GB of RAM for a single installation), the Linux support (product itself could be installed on a Linux distribution) and the built-in database.

VMCEVeeam 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 to a major version of Veeam products.

Now more informations are available about this program, included a list of training centers.

One possible issue during an upgrade to VMware vSphere 5.1 or 5.5 (but also in a new installation) is related with the introduction of the the SSO (introduced in vSphere 5.1) component in vCenter Server that handle the authentication across the different vCenter Server components, but also against the users.

In some cases you may have the following issues during the user autentication:

  • You can log into vCenter Server 5.1 or 5.5 with the vSphere Client or vSphere Web Client only with local users
  • Logging into vCenter Server 5.1 or 5.5 using the vSphere Client with an Active Directory domain account and/or selecting the Use Windows session credentials checkbox, fails with this error:Cannot complete login due to an incorrect username or password

During the past months I’ve seen some posts and tweets enthusiastic on the a possible introduction of new server’s series based on ARM processor, with some considerations on how they could change the actual scenarios, for example in the virtual infrastructures.

But I have really some doubts in the server scenarios or at least in the virtualization user case: first to all we have to notice that most of the hypervisor are designed for the Intel/AMD server. Actually VMware vSphere (but also Microsoft Hyper-V) is working only with Intel/AMD x64 platform in order to provide only x86 and x64 virtualized platform.

Of course this does not mean that there isn’t any virtualization opportunity with ARM based processor. For example there are some interesting project in the OpenSource world, like the Xen porting. And both VMware and Microsoft have the possibility to build a porting to the ARM processor, but the result will be an hypervisor that can virtualize only ARM platform (virtualization is not emulation, it work like a software partitioning of the existing resources).

Some months ago I described the characteristics of a new Dell’s product, intended to redefine the existing server form factors and the server converged concept: Dell PowerEdge VRTX is the first and so far only Dell product (at present there aren’t similar solutions for other vendors) to merge together three different form factors (tower, rack and blade) into one with unique characteristics.

It could be defined a Data Center in a box, or (using a quote from Dell) a (private) Cloud in a box. Basically it’s an integrated tower format system (complete with wheels if you need to move it) that could be also rack-mountable (in that case it will oriented horizontally and will fill 5U) with most of the functionality of a Dell blade solutions, but also some unique functions. It include a server part, a storage part and also a networking part, all in a single system.

Unlike the PowerEdge C line (already existing from several time), in this case the storage is shared between the servers and the servers are in the same blade form factor, being able to benefit from the same components from the blade line (althought the blades are designed with a specific fabric for this solution). In contrast, the VRTX solution is less dense, but it is not his main purpose and its market position.
