IaaS vs. PaaS vs. SaaS

One of the several interesting topics discussed in the recent event Cloud Communities Day, held on Monday 22 in Milan and with the presence of various communities, as well as analysts and academics, was which could be the most interesting type of cloud. If we limiting to the three basic types: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) or Software as a service (SaaS)... Which one could be the more interesting? As often "it depends" could be the answer, but paradoxically, many have very clear opinions about it (though it is not said that all fit together ...). In ...

EqualLogic Replica aborted because the group was too busy processing a max-keep value change

Recently I've got a strange issue with an Dell EqualLogic environment and I've not found any useful info about the related error message: Subsystem: MgmtExec Event ID: 8.3.48 Schedule Replica oraria aborted because the group was too busy processing a max-keep value change to create the operation scheduled for time ... The detail does not help and also the EqualLogic reference guide does not report this error message. This issue happen after a member (to be honest was a group) upgrade and probably the replication sets was damaged during this event. The resolution is really simple (it does not fix itself, also after some days): delete ...

VMware vSphere 5.5 - Upgrade or not upgrade?

The new VMware vSphere 5.5 has some interesting new features and scalability properties that make interesting for each new environment, but also for existing customers (considering that the license key remain still the same of the 5.x feature). So could make sense start using directly this version instead of the 5.1 and upgrade all existing environment to the new version 5.5? Like each new version you have to make some consideration first and especially before starting the upgrade procedure. The main consideration is that each new product (does not matter that is a major or a minor release) bring new features and ...

Storage for VDI: local or shared?

In my interview with Sakthi Chandra (NexentaVSA for View Director), during the last Open Storage Summit EMEA, we have talk about the Nexenta approach of the storage for a VDI environment. Their product has been developed from a collaboration with VMware and some aspects sound familiar: for example the overview of the VSA deployment and design seems similar to the VMware VSA, except the scalability limit (that is limited to max 3 host for the VMware solution). But I don't want talk about the product, yet (I prefer dedicate it a post, when I will be able to make some ...

Purging old data from a View Event DB

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 ...

How to add ESXi custom drivers using an USB key

As written in the previous post, one common issue with recent servers of new generations is that maybe the NIC drivers are not included in the standard ESXi ISO. An if you use the vendor (or a personal) customized ISO, could be possible that during a patch update or a version upgrade you loose the drivers and the system is no working anymore. In those cases you may have an ESXi that complete his bootstrap, but without any network connectivity is not usable and could be hard to fix the missing drivers because VUM and other remote tools tools could not ...

My thoughts on VMware beta exams

The VCP5-DT beta period has already finished, so I would to update my thoughts on VMware beta exams (my first post about them was around one year ago). Beta vs. Regular exams Beta exams usually are for a small period before the run of the regular exams. Usually in the beta exams you have more time, more questions and a way to give feedback. Also the sign-up procedure could be different and is not possible to re-take a beta exam. The results of the beta exam are available not after the exam (as it is usual for most of the regular exam), but ...

Virtual CPU and Virtual Cores

In a physical environment usually the term CPU is used to refer to the physical package (or socket). The real processing unit inside this package are called cores (and not that each core can have inside more ALU and can be seen as more logical cores with hyper-threading feature). More CPU usually define a SMP system, more cores a multi-core CPU, more CPU each with more cores a complex system (usually the NUMA architecture is used in this case). In a virtual enviroment the term vCPU is used to refer to a core assigned to a VM. More vCPU define a ...

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 ...

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 ...

Is VTL dead?

One curios thing of both ExaGrid and Dell DR4000 solutions (but also other solutions) is that they lack of a Virtual Tape Library (VTL) feature and only work as a network share (with CIFS or NFS). In both cases the reason was not technical (but I think that the main reason is still just a way to reduce cost and complexity) but marketing/strategy (customers just don't ask at this feature). But moving from a backup to tape (B2T) to a backup to disk (B2D) solution does not necessary mean move to backup to file (over a share) solution. All backup applications ...

How to verify a VMware Certifications

Some days ago there was a case of one guy that was using VCDX certification (and several other certifications) without having it (or at least without demonstrate it). One of the biggest problem in certification credibility is avoid fraud. Of course some could gain the certification with cheats and other form of frauds, but for some kind of certification (like the VCDX one) this is not possible: who gain it usually deserve it. Actually there is a transcript tool for VMware certifications (and also for some accreditation) but it's not public. You have your transcript in your own account. Also for each ...

VMware View 5.1 – Disable the certificate warning

One year ago, I've described how to disable the certificate warning in the Windows View Client 5.0, by using GPO or a direct change in the local registry (on the client). Now, with the new version 5.1 of the View Client there is a new way client side: As you can notice, there is a new option "Configure SSL..." that can open this window: In this window you can choose the right behavior. Note that on the smartphone and e tablet version of the client, on each connection you can choose the behaviour (in case on not valid certificate). But remember that the right approach ...

VMware Tools 5.1 upgrade may restart your Windows VM

One of the new features of vSphere 5.1 was upgrade procedure of the VMware Tools on Windows VMs: when you upgrade them the first time to version 5.1 (the right version number it's 9.x), other upgrade will not require any reboot of your Windows system. For Linux VMs there is no need to reboot the system (but I suggest in order to be sure that the kernel modules are loaded proprerly), and now also Windows VMs could have a zero downtime upgrade. But it's really true? Honestly I found that on some VMs the automatic upgrade procedure of VMware Tools will also ...

Building a vSphere 5 lab

For people that need to make practice for the VCAP-DCA exam (and the beta of VCAP5-DCA will start soon) a good lab environment is mandatory. But it could also be useful for other reasons, like demo environment. There are several options to build one, but most used solutions are using nested hosts on one physical system with: VMware Workstation/Fusion over a host OS: common for a notebook. ESXi 5 on a server or a whitebox: common if you plan to have a always-on or fixed solution. Actually both solution could be good, but Workstation could not scale too much, expecially if you work with ...

VMware Logo

As written in a previous post, VMware NSX was one of the cool topics during the past VMworld and new version of this products has been announce.

User cases are more and more and probably one of most interesting (and natural) usage of Network Virtualization is the micro-segmentation. This can give an immediate advantage in using this technology, and can also give an answer to a common security issue.

Today’s security models are focuses on perimeter defense, but continued security breaches show this model is not enough. A deep and more granular approach is needed to provide more security and more control.

Of course, in this VMworld 2014 there is space also for NSX with lot of sessions, user cases and related news. Related news maybe are not so big as in the past year (the first official announce of NSX), but anyway there is something interesting.

First to all the certification path on Network Virtualization: as written in a previous post, there are already the first (big) group of VCDX-NV. Now the certification page is update also with the blueprint for VCDX-NV and VCP-NV (you can already ask for the authorization for it) and the new certification VCIX-NV (instead of the VCAP level) will be also available soon.

Other news are related to new product releases: NSX for vSphere 6.1 and NSX Multi-Hypervisor 4.2.

As written in the previous post, there are different approaches for implement a SDDC and EVO:RAIL represent the VMware’s way for implement fast and in a simple way an Hyper-Converged Infrastructure.

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). But in this case will be ONLY thought this way: if you want to play with EVO:RAIL you must buy an entire solution or use the Hands on lab. Announced partners include Dell, EMC, Fujitsu, Inspur, NetOne and SuperMicro.

The 2014 edition of VMworld US is started and, as usal, there are several news related to the VMware world (by the way, if you are not attending at VMworld, don’t miss the VMware NOW online event). Some are well know (like VVOLs or recent company acquisition), other will revealed during this event.

But apart the news themselfvel, the focus and the vision of VMware is evolving in this years to something more cloud oriented, or at least more and more close the cloud’s pillars: Abstrastrion, Automation and Agile.

The VM is still present (and most of the policies are VM centric), but the triple-A is driven the evolution. Starting from the Software Defined Datacenter (SDDC), that (in VMware’s vision) is still the Future of IT.

Atlantis-Logo

I’ve already write about Atlantis ILIO USX in some previous posts (for example look at the one related to Virtualization Field Day 3). Their solution is a in-memory software-defined storage solution that pools existing SAN, NAS and DAS from across the datacenter and then optimizes how server applications and VMs consume this storage.

Now Atlantis Computing has announced the new version 2.0 of this product with the promise to enable enterprises to deliver better than flash performance, for half the cost of traditional SAN.

With USX they are jumping in the storage world making their ILIO solutions more than an storage acceleration product, but also a full software-defined storage that can work also as a storage virtualization.

VCDX-DCV

In the past days a new bunch of VCDXs (around 30) are appear, but the interesting news is that they are (or at least most of them) VCDX-NV: the new track specific for Network Virtualization (that mean mainly VMware NSX).

Seems that they are all coming from the NSX Ninja program and most of them where already Cisco CCIE (matching the criteria described on the VCDX-NV official web page). This also may confirm that there isn’t a real VCAP level for the NX path (as already commented in a previous post and also supposed in this post).

Veeam has released another great free tool: Veeam Task Manager for Hyper-V. Veeam Task Manager for Hyper-V is also one of the many new features in Veeam Management Pack v7 for System Center.

Veeam Task Manager provides detailed Hyper-V performance monitoring metrics for CPU and memory at the individual VM level so you can identify which VMs are using the host resources. The metrics are updated every three seconds by default and can be configured to update less frequently if desired.

And Veeam Task Manager for Hyper-V is not only free, but is also a portable (this lightweight tool can run from any USB device for emergency troubleshooting without any installation or integration) standalone performance monitoring tool.
