Nutanix OS 3.5: Deduplication, New GUI, SRM, Hyper-V Support

Nutanix LogoNutanix, one of the fastest growing IT infrastructure startups around, shows no signs of slowing down with their release of Nutanix OS 3.5. For those not familiar with Nutanix, they offer a truly converged virtualized infrastructure. This generally consists of four nodes in two rack units of space, where each node has CPU, RAM, traditional fixed disk, SSD, and Fusion-IO flash built in. Their secret sauce is really NDFS, the Nutanix Distributed File System, built by the same folks that created Google’s File System, as well as a unified, hypervisor-agnostic management interface.

OpenStack and the Software Defined Data Center (SDDC)

OpenStack Logoopenstack-cloud-software-vertical-smallThe OpenStack Summit this week continued to fan the flames of the software-defined data center. The software-defined data center is just a term for replacing traditional data center hardware functionality with the same features implemented in software, running on commodity x86 servers. While software-defined approaches to data center features are at least nominally less expensive than their hardware counterparts the real promise in the approach is flexibility and management ease with high levels of integration. Reconfiguring a network to support the security requirements of a new application is now just a function of  software and APIs. Expanding storage is just simply adding another node with more storage attached, and the cluster compensates automatically. Even things like firewall rules and load balancer configurations can now be stored as templates along with the applications, to be provisioned in minutes.

Windows 2012 Hyper-V – the hypervisor for your Cloud? Part III

DataCenterVirtualizationWindows 2012 Hyper-V is the hypervisor for the cloud. VMware’s vSphere is a dead man walking?

In parts One and Two I shared a chunk of what I learned from Aidan Finn‘s enlightening and entertaining session “Windows Server 2012 Hyper-V & VSphere 5.1 – Death Match” delivered at the E2E Virtulisation Conference in Hamburg.  We’ve considered pricing, scalability and performance, as well as storage  then gone on to consider resource management, security and multi-tenancy and what a flexible infrastructure can give.

Some have found this a useful comparison. Others have highlighted that this isn’t a feature-by-feature comparison and that if it was, the tables would be very different: they would, they’d be longer for a start.  But more importantly, would they give the high view that many are focused on? Is the goal a technical  Top Trump  victory, or alignment to business goals? If aligned, how aligned? A friend used to often quote the difference between cabinet making, carpentry and joinery is effort and measurement: they each had their place, the trick was knowing what level to apply.

In Part III, lets question further Aidan’s premise that Hyper-V kills vSphere. Here we’ll consider High Availability and Resiliency.

Windows 2012 Hyper-V – the hypervisor for your Cloud? Part II

DataCenterVirtualizationWindows 2012 Hyper-V is the hypervisor for the cloud, VMware’s vSphere is a dead man walking?

In Part I I shared a chunk of what I learned from Aidan Finn‘s enlightening and entertaining session delivered at the E2E Virtulisation Conference in Hamburg tastefully titled, “Windows Server 2012 Hyper-V & VSphere 5.1 – Death Match”. In Part I we looked at pricing, scalability and performance, as well as storage in questioning how bold this statement was.

Pure license-cost wise, it more straightforward to run Microsoft Hyper-V than add another licensed hypervisor: note that Hyper-V does have a free offering (although this version doesn’t cover the virtual Windows Server instance licenses). We showed that scalability wise, Hyper-V can better common competition. Storage-wise Hyper-V, as should be expected from the newest offering, supports the newest technology: 4k sector sizes, and had the largest virtual disk support. Still, if you needed greater than 2TB of storage, you could always join multiple 2TB instances together, or bypass limits by mapping a LUN direct to the VM.

Still, besides pricing simplicity, performance improvements, and updated storage what has Microsoft done for the latest version of Hyper-V? In Part II, lets question further Aidan’s premise that Hyper-V kills vSphere.

Windows 2012 Hyper-V – The Hypervisor for your Cloud? Part I

Windows 2012 Hyper-V is the hypervisor for the cloud, and VMware’s vSphere is a dead man walking. So declared Aidan Finn at a recent virtualization conference in Hamburg during an enlightening entertaining session which he tastefully entitled, “Windows Server 2012 Hyper-V & VSphere 5.1 – Death Match”.

A bold statement? Hyper-V has often been cited as a “nearly ran”; good enough for the SMB space and smaller Private Clouds, but lacking the muscle for a cloud-focused enterprise. Nice for a visit, wouldn’t want to live there.

A biased statement? Aidan Finn is highly regarded Hyper-v Microsoft Most Valuable Professional and regularly writes on his website about changes and features of the product. In Predicatably Irrational, Dan Ariely dedicates a chapter to the possibility of a fan’s judgement being clouded. And yet, the list of features now available in Windows Hyper-V is compelling. Indeed, back in March we discussed if Microsoft would drive a wedge between VMware and EMC with Windows Server 2012 and Hyper-V.

In terms of embedded services and experience, VMware’s vSphere has a significant place in many organisations’ data centres. Licensing alone is unlikely to change hearts and minds to convert, but what about features?

Can Microsoft claim that Hyper-V is the hypervisor for the cloud? What new features are available in the 2012 release, and how does it now compare to vSphere 5.1. More importantly, will  these changes drive wider adoption?

In this first installment, we take a look at pricing, scalability, and performance, as well as storage.

Hotlink’s Cross-Platform Management Technology

DataCenterVirtualizationOne of the companies and technologies to watch is Hotlink with its Cross-Platform Management Technology (winner of Best of Show, VMworld 2012). If you have not heard of this before, I think you will in the near future. This technology allows you to use VMware’s vCenter Server to manage and control all major hypervisors and public clouds to include VMware vSphere, Microsoft Hyper-V, Citrix XenServer, Red Hat Enterprise Linux (KVM), CloudStack, and Amazon EC2, all from within VMware vCenter.
