How to verify other IT Certifications

In the previous post I've define some ways to verify a VMware certification, to avoid frauds and wrong usage of false credential. Note that VUE give also a way to authenticate a Score Report. For other certifications there are different ways and, in some cases, could also be simplest: Microsoft: for all this kind of certification there is a specific portal (Validate MCP Transcript) where you can put the MCP ID (each certified people has a unique ID and this does not depends on the certification type) and a password (defined by the certified guy) and get the entire transcript of all Microsoft certifications. ...

Virtualization types

With the term virtualization usually we are talking about System Virtualization, where a physical system is "partitioned" to permit multiple environments (using virtual machines). But virtualization is more generic and include different types: System Virtualization or Platform Virtualization: the hypervisor layer permit multiple virtual machines (VM). There are mainly two sub-types: Server Virtualization: where VMs are usually server OSes with server roles. Desktop Virtualization: where VMs are desktop OSes. There are two different approaches: Server Hosted: where VMs are running on physical server machines (usually using hypervisor for server virtualization). Also called VDI (Virtual Desktop Infrastructure or Virtual Desktop Interface). Client Hosted: where VMs are running ...

Using PCoIP on WAN connections

In a View environment the PCoIP is usually the right choice and on a LAN works really well (see also the previous post about PCoIP and RDP differences). But on a wide-area networks (WANs)you have to consider some aspects to have a reasonable reactivity or to maximize the number of remote clients: you must consider bandwidth constraints and latency issues. The PCoIP display protocol provided by VMware adapts to varying latency and bandwidth conditions, but some optimization may be needed. The best reference document is the VMware View 5 PCoIP Network Optimization Guide with a lot of useful information.  But there ...

Copy/Paste in a VMware View session

Probably you have already notice that copy & paste operation in a VMware View session are limited for security reasons and is discussed in the View admin guide: Configure clipboard redirection Determines the direction in which clipboard redirection is allowed. You can select one of these values: Enabled client to server only  (That is, allow  copy and paste only from the client system to the View desktop.) Disabled in both directions Enabled in both directions Enabled server to client only (That is, allow  copy and paste only from the View desktop to the client system.) Clipboard  redirection is implemented as a virtual channel. If virtual channels  are disabled, ...

Hyper-converged storage momentum

Hyper-converged architectures consolidate and manage computing, networking, and storage resources via software so they can run on any vendor's server hardware. Several years ago they where (apparently) strange approach to storage implementation used mainly for cheap solution (using VSA, that lacks, in much cases, of right scalability), or for special user cases like ROBO or VDI (with solution like NexentaVSA for View). But starting with Nutanix (probably the first real player in those kind of solution) the idea of simple VSA (Virtual Storage Appliance) has dramatically changed by introducing a large scalability with new scale-out (or web-scale, using Nutanix terms) approach. VMware is talking about ...

Manage a storage array with System Center VMM 2012

One of the interesting features of System Center Virtual Machine Manager 2012 is that it can handle several other objects and not only the VM (when the name will be changed to reflect this?). Of course it can handle hosts (not only Hyper-V hosts), but also networking and storage. All those resource are in the "fabric" tab. In this case we see a storage array with its LUNs: The storage integration in System Center is really similar to several storage plugins for VMware vCenter and the VASA functionality on vSphere 5 (in fact it also require a "provider"): you can manage your ...

Approaching the SMB segment

The challenge! SMB segment could be a (big) challenge due to the following reasons: Requirements: in most cases are the same of the enterprise segment. For example the required availability and SLA are really close and may imply similar solutions to achieve it. Constraints: are really different and in most cases very strictly. For example budget, but also the IT staff and skills. Evolution: and SMB may have big trend in evolution (or involution). Note that also in SMB, disaster recovery, business continuity, availability and security aspects have still to be considered. This kind of market remain still interesting, considering the number of the companies and ...

VMware Horizon for View 6.0 upgrade path

VMware has announced and released Horizon for View 6.0 several months ago. I've already discussed about the news of this product (remote apps and app pools is probably one of the most evident). The upgrade procedure is almost similar with previous procedures (see upgrade to View 5.3 or View 5.2) and it's well document in the official Horizon View 6.0 upgrades guide. Remember to check first the compatibility guide (and verify with version of vSphere could be used) and finally to upgrade also the AD GPO templates. But there are some significant changes that you have to consider in your upgrade path: Starting with ...

What's happen to the virtualization ecosystem?

In the last years, in the virtualization ecosystem, there where three big trends: one is the shifting from a single hypervisor to a multi-hypervisors (originally was mainly a VMware ecosystem, now is a virtualization ecosystem) the second is the reduction of the number of players, at least in some fields like backup e monitoring, due to some acquisitions (for example Quest has bought VizionCore and VKernel... Novell has bought Platespin...) the third is that the big vendors are directly involved and in competition: for example VMware is working on some solutions, like VDR for backup (although is a limited solution) or vCenter Operations ...

ESXi - More on partitions

In a previous post I've described the partitions used by a ESXi installation (see ESXi – Partitions layout of system disk). Partitions are formatted with a FAT16 filesystem, but the ESXi files are stored into the banks partitions with a specific system that consist in some compressed archives containing the required files or more archives (as also described in the yesterday's post about the reset of the root password). More details on the filesystem used is on the first number of the VMware Technical Journal, in the paper: VisorFS: A Special-purpose File System for Efficient Handling of System Images. But for a ...

EVO represents an entire new family of Hyper-Converged Infrastructure offerings from VMware, and EVO:RAIL represents the first product in this family. It was announced in this VMworld 2014 (with a first list of EVO partners) and will be available during the second half of 2014. Note that this product will be available only through qualified EVO partners (similar in the concept on how vSphere could be sold through a pre-installed OEM channel). ...

Issue in VM migration: MAC Address may change

Recently I got a strange issue using a cold storage migration usign the Migrate function of vCenter Server. This was the scenario: a Free Hypervisor with some VMs where a full license (Essential Plus) was added and the host was also added to a vCenter Server. For compatibility matrix reason the version 4.1 was used (although the storage can work with vSphere 5.0 but officially was not supported). Also the Free Hypervisor was build with the 4.0 version and upgraded (one year ago) to the 4.1 version. This was the issue: after a cold storage migration all the VM build when the ...

New in vSphere 5 - VMware HA advanced options

With the new HA implemenation, something has changed also in the advanced options with new parameters, but also with some that now are no more available. For a list see Supported vSphere 5.0 Advanced Options. One options that has been removed “das.failuredetectiontime”. The reason is well explained in Duncan's HA Deep Dive: I know many of you used this advanced setting to tweak when the host would trigger the isolation response, that is no longer possible and needed to be honest. If you’ve closely read my other articles you hopefully picked up on the datastore heartbeating part already which is one reason ...

Manage an isolated Windows Server

There could some cases where you may have some Windows (Server) completely isolated from the Internet, for example in some appliances or storage solution. One interesting aspect that learn on Windows products during a DataCore training was that in this case you can have some delay in the user interface, both on the DataCore GUI, but also on the Windows one. This is related in driver management (and in signign verification) and is well described in a FAQ on DataCore site (DataCore Server GUI takes longer than expected to open). The solution is quite simple and consist in a simple change on the ...

VM replication in VMware SRM 5.0

One of the interesting feature of VMware SRM 5.0.x is the vSphere Replication (VR) technology that is a VM a replication engine (part of SRM 5.0 and that also requires ESXi 5.0 and later) to implement protecting and replicating virtual machines between sites without the need of storage array–based replication (that usually it's costly and too much vendor dependent). It use different elements: VRA (vSphere Replication agent): included in ESXi starting from v5.0 VRMS (vSphere Replication Management Server): one virtual appliance (VA) for each site to handle the communication VRS (vSphere Replication Server): one virtual appliance (VA) on the DR side that is just ...

ESXi - How does the dual bank work?

As written in the previous posts, in the ESXi installation there are two copy of the system image located in two different partitions (see Partitions layout of system disk and More on partitions posts). The actual system image is located on the first 250 MB partition, formatted with plain old FAT16 filesystem, but using a special pseudo-filesystem on it (see VisorFS: A Special-purpose File System for Efficient Handling of System Images). The image itself, s.v00, is a 124 MB compressed file, which is decompressed on boot and contains the hypervisor operating system. Note that the compressed image is larger in 5.0 ...

In the previous post I’ve talk about 3CX and their main product (3CX Phone System), its characteristics and the different users cases. Now it’s the turn to describe the installation, that it’s really simple, easy and fast, and also well describe in the Administrator Manual.

As written this product require a Windows operating system, but it support several version, included client edition of Windows. From NT 6.1 (Windows 7 and Windows Server 2008 R2) almost are supported, but installations on Microsoft Windows server Core versions is not supported. Installations on Small Business Server 2008 are not recommended. However if you wish to use SBS, ensure that you use Abyss as a web server.

Windows embedded or Windows Storage Server are not listed, but I guess that it can work without big issues and can be interesting to build customized appliances.

Microsoft Logo

Last October, Microsoft and Docker, Inc. jointly announced plans to bring containers to developers across the Docker and Windows ecosystems via Windows Server Containers, available in the next version of Windows Server. This was for sure a big announce, considering also the containers momentum, but was just an announce, considering that no details was avaiable (and of course none is available yet in the the beta code of Windows Next).

But finally there are the first details about this new technology and how it will work. Microsoft has announce it both on the Windows Server and Azure blog: continue reading…

APAC edition of #vBrownbag is managed by my friend Alastair Cooke (the creator of AutoLab) and actually he is covering the VCP6-Desktop blueprint. One big news of the new version of this certification is the part related to VMware Mirage: the entire section 5 is dedicated to Install, Configure, and Manage VMware Mirage.

How don’t know how much will impact the related exams (I’ve not took it yet), but for sure mean a more End User Computing perspective rather that something related only to the View part.

In the next APAC #vBrownbag session I will give an overview of VMware Mirage and following the different blueprint objectives:
