Eric Siebert (from Sphere-Land.com) has open again (see the related post of previous year), a contest for voting the ‘Top VMware & Virtualization Blogs’. This contest is becoming a recurring and estemeed in the VMware & virtualization world (see also the history of the top blog voting over the years).
Last year over 1400 people voted from 60 different countries, with over 320 blogs dedicated to VMware and Virtualization – this is definitely an impressive number which is a real indication to how passionate people feel towards the VMware range of products and virtualization in general.
This year the content is sponsored by Infinio and it’s available on this site: http://info.infinio.com/topvblog2015
With the new VMware vSphere 6.0 there are several improvement in the availability related features. Although the vSphere HA apparently has not changed so much (of course now support a bigger cluster with 64 nodes), there several aspects that have been improved or changed:
The primary reason for becoming vExpert certainly should not be related to any possible benefits of the program. And once confirmed (for me is the sixth year in a row) you have to think more about what you can give rather to what is to be expected. But I’d be a hypocrite to deny that there are also practical advantages in being a vExpert!
Officially, VMware, according with the vExpert FAQ, say that the biggest benefit of the award is the public recognition as a VMware vExpert Award winner.
Interesting European IT events:
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.
After the E2EVC 2014 Brussels and E2EVC 2014 Barcelona events, the next European E2EVC event (and the first one for 2015 year) will be in Berlin:
The next Spring E2EVC Virtualization Conference in Europe in summer 2015 will take place in Novotel Berlin Mitte Hotel, Fischerinsel 12, 10179, Berlin, Germany.
E2EVC Virtualization Conference is an independent, non-commercial, virtualization community event build from experts to experts. Started in 2003 with just 4 people and after 23 very successful events grown to awell-recognized event with over 140 attendees.
Maybe we can say with no limit, or at least, to be serious, with really huge numbers compared to the actual needs and the existing compunting power. Those new limits are both for scalability aspect, but also to fit with possible performance requirements, considering that a bigger number of business critical applications are going in the virtual environment.
With the new VMware vSphere 6.0 there are a lot of changes, and some of them are in the new vCenter architecture both for the Windows installable version and the virtual appliance (vCSA) version. For this reason the design aspects and the deployment scenarios are changed from the previous version (see VMware vCenter 5.5 design).
Windows vCenter installation experience has been enhanced with additional capabilities including custom ports, custom paths, uninstall and error messaging improvements and vCenter Server Appliance (vCSA) now has a guided installer. Furthermore, all upgrade paths from Windows vCenter 5.0 and up are now supported.
Some considerations remain still the same (like the DBMS placement, or choosing between a physical or virtual deployment, or finding a good high availability architecture), but other are different, starting from the different vCenter components that now have been simplified with a logical separation between management and core&security roles.
PernixData FVP is a Flash Hypervisor software that aggregates server flash across a virtualized data center, creating a scale-out data tier for accelerating reads and writes to primary storage in a simple and powerful way. Was one of first (probably the first) to implement a fault-tolerant write back acceleration.
Stating from version 2.0 they add both memory support (instead or with flash) and NFS support (previously they where only block level).
Now the latest version of PernixData FVP software (version 2.5) will add following new features:
After the new Virtual Volumes, the most “spoilered” features of the new VMware vSphere 6.0 was probably the new vMotion that allow VMs to move across boundaries of vCenter Server, Datacenter Objects, Folder Objects and also virtual switches and geographical area.
VMware vMotion was probably the first important virtualization related features that make important VMware (and its product) but, much important, that make relevant the virtualization approach: having VM mobility means handle planned downtime and also workload balancing.
Now VMware reinvent vMotion to become more agile, more cloud oriented: breaking the boundaries and going outside the usual limit make possible have VM mobility across clouds. Note that actually it’s not (yet) possible use this feature to live move to or from a vCloud Air service… but of course this is the first step to do this in the future.
In previous versions of vSphere, the vCenter Server was not suitable to provide directly cloud based functions: vCloud Director was the way to build a Software Defined DataCenter (SDDC) at the top of vSphere and provide more functions and concepts that were not available in vCenter. But, during the VMworld 2013, VMware introduced a new product strategy and direction for vCloud Director (vCD): VMware would like to move forward with a plan to converge vCD functionality into the vSphere and vCloud Automation Center (vCAC) product lines or (as another direction) in the virtualization platform (that means inside vCenter Server)
The new vCenter Server 6.0 goes in the second direction that does not exclude the first one (to be more precise, bring some functions in the lower level will help to add more at the top level with tools like vCAC).
During this years, some legacy components of the vSphere suite has been dropped, starting from removing (in vSphere 5.0) VCB, Converter Enterprise, Guided Consolidation, and the historical ESX Server. The latest removal was the TPS memory management (in vSphere 5.5 with latest patches).
In those year the old vSphere Client (the Windows client side) has been deprecated (from vSphere 5.1) and all new features and functions has been introduced only in the vSphere Web Client that is a web oriented client, multi browser and multi platform.
But for several operational tasks and for all the legacy vCenter plugin, the old vSphere Client was still necessary, and of course was necessary to manage a single ESXi host without having vCenter Server (the server part of the vSphere Web Client is a vCenter component). Also there were some limits in the Web Client.
