Ravello ’s Smart Labs have self-contained capsules to run your VMware/KVM development, test, training and demo environments in the cloud without migration. One unique feature of Ravello platform is that you can simple run on AWS or Google Cloud, without any changes,  VMware vSphere workload or also ESXi nested!

It’s very nice for testing or lab purpose, where you don’t need anymore of local resources and you can have the speed and the elasticy of the cloud.

Veeam has realesed the Veeam Backup & Replication 8.0 Update 2b (see KB 2024) that add several performance improvements in the update 2 of the product.

Note that Veeam Backup & Replication checks for updates automatically once a week (unless you have disabled that). This means that everyone who had not updated yet should get a notification within the next 10 days or so.

B&R 8.0 Update 2a was officially released at the begin of June, but there where a new critical issue in VDDK 6.0 that forced Veeam to rebuild the update code again, now as Update 2b, adding a workaround for a single specif issue:

The 2014 spring (EMEA) edition of E2EVC is now over and it’s time to archive it and take some considerations.

E2EVCE2EVC Virtualization Conference is an independent, non-commercial, virtualization community event build from experts to experts.

This edition was from Fri 12 to Sun 14th June 2015 in in Novotel Berlin Mitte Hotel, Fischerinsel 12, 10179, Berlin, Germany.

This was my third E2EVC event (I’ve attend at the E2EVC XX Rome and E2EVC 2014 Brussels) and I can confirm the reason to attend at this kind of event (see E2EVC 2014 Brussels: Why attend).

Until now Microsoft simple does not support nested virtualization in its Hyper-V product. Nothing wrong with it, but it’s a case where not supported means also that it simple does not work at all.

So the only way to test Hyper-V (or other hypervisor) in a lab with a single physical system (server or client) was using other hypervisors (VMware ESXi, Workstation, or also Paralles or others). Or using this trick (useful also with the new hardware requirement of the next Hyper-V) but with the big limit where the VMs cannot be powered on at all.

Now with the next Windows Server release (Windows Server 2016) there will be some changes. According to a Build Conference session (Windows Containers: What, Why and How), seems that Hyper-V Windows Server 2016 will support nested Virtualization.

Recently I’ve got a strange issue on ESXi 6.0: after an host reboot the ESXi hosts display a false positive warning:

Deprecated VMFS volume(s) found on the host. Please consider upgrading volume(s) to the latest version


Starting with vSphere 6.0 the VMFS3 version is now deprecated, but in my case all block based datastores were already at VMFS version 5!

As written in a previous post, during this days I’m attending at the Nutanix .NEXT Conference where several big announces have been revealed during the first keynote.

Really a lot, that I will need more to fix and digest them. Most of them are listed in the press release.

New product, new software, an integrated scale out file server, … make it simple and make it invisible were the main themes for the new infrastructures.

Nutanix is a well know hyper-converged company founded in 2009 with the vision of bringing the benefits of web-scale IT to the masses. They have changed the rules of traditional storage (on 2009 mostly SAN based) and become the pioneer of concepts like no-SAN and no-LUNs, hyper-converged and web-scale storage.

Recently they have also reach five years of history, were they have made significant progress in their products and solution (and also partnership).

And now they are handling their first ever user conference (the .NEXT Conference) at the Fontainebleau Hotel in Miami Beach in 8-10, June 2015.

With the new Windows Server 2016 Technical Preview 2 there are more features as described in a previous post. Some are also releated to the storage part of Windows Server platform where starting with Windows Server 2012, Microsoft has introduced lot of features including SMB3, de-duplication, a new filesystem for huge volumes (ReFS), storage spaces and the Scale-Out File Server solution. And with Windows Server 2012 R2 also a multi-tiering.

With Windows Server Server 2016 are added Storage Replica (to build, for example stretched cluster), an improved storage QoS, a better deduplication engine and a completly new Storage Spaces Direct (S2D).

The last one is the more interesting because it makes the Scale-Out File Server a real scale-out architecture.

Some weeks ago I was invited to as a delegate at the first edition of Data Field Day (#DFD1) event, scheduled in May 13–15, 2015 in California (Silicon Valley and San Francisco).

Data Field Day event purpose was to cover different topics from others Technical Field Day events: from big data to analytics to hyperscale architecture and cloud security, and all waves of innovations that are transforming the IT. A new format for some growing trends, including micro-services, mobile and the Internet-connected world.

As written in a previous post not all presentations where completely in topic: some where too much storage oriented. But for the first edition of #DFD1 this was acceptable. Cloudera was one of the cases where this issue was not present.
