In the previous post I’ve introduced some concept of the Nutanix approach to the storage (and not only, because it include also the compute and the networking part).

Basically we can use the slogan “No SAN”, but as written is more than a simple local storage approach.

To have more information and some example also of the user interface see this documents:

Nutanix is a start-up company founded in in September 2009 with the scope to realize a new SAN-less virtualized datacenter platform, converging two tiers of infrastructure down to one. On May, 14th 2012, Nutanix has officially started its EMEA division.

The introduction video explains most the the basis concept of Nutanix storage approach. Also there are other blog that have a more exhaustive introduction (see in the final reference).

DataCore Software is an independent software vendor, founded on February 4, 1998 in Fort Lauderdale, Florida, specializing in storage virtualization, storage management, and storage networking.

Its main product, SANsymphony-V (now at the V9.0) forms a transparent, scalable virtualization layer across your storage infrastructure in order to enhance its capabilities and centralize its management. The many nuances that distinguish one model or brand of storage from another and render them mutually incompatible no longer stand in the way of using them together.

Storage is an important part of a virtual infrastructure, but compared with the server part (that provide computational “power”) the different storage vendor’s solutions are not so homogeneous and easy to compare or understand. Of course because there are different positioning but also a lot of different aspects, but in most cases, the most important aspects are also the “hidden” or the less described.

What is probably clear is the difference between local storage (DAS) and shared storage (SAN or NAS, but sometimes also some kind of DAS) and why shared storage is so important: not necessary for the performance aspect, but mainly because it is required by design! In a virtual infrastructure for system virtualization (VMware vSphere, Microsoft Hyper-V, Citrix XenServer, KVM, …) a shared storage is required to provide some core features (like HA and VM hot-migration)… This could change in the future (for example let’s consider Marathon everRun VM without a shared storage), but actually is just a requirement. And of course also a plus, because it can provide different other improvements.

In a previous post I’ve described how ignore the warning in a View 5.x environment. But the right way so solve this “issue” remain replace the self generated and signed certificates with new one signed from a trusted CA (a public on, but also an internal one could be fine, if you can push its certificate on all the clients). This may become a mandatory requirement for future version of View (although it is not yet confirmed).

For how generate and replace the certificates see:

Some weeks after the announce of the DynamicOps acquisition intent, VMware has announced it has signed a definitive agreement to acquire Nicira, a pioneer in software-defined networking (SDN) and a leader in network virtualization for Open Source initiatives.

VMware will acquire Nicira for approximately $1.05 billion in cash plus approximately $210 million of assumed unvested equity awards. The acquisition is subject to regulatory approvals and other customary closing conditions. The parties expect the acquisition to close during the second half of 2012. The acquisition has been approved by the boards of directors of both VMware and Nicira and the stockholders of Nicira.

But what is the Software-Defined Datacenter? Basically could be the foundation of Cloud Computing. Cloud computing is about agile, elastic, efficient, and reliable services, and it is achieved through sophisticated software that abstracts hardware resources, pools it into aggregate capacity, enabling automation to safely and efficiently dole it out as needed for applications. Tenants or customers utilizing the software-defined datacenter can have their own virtual datacenter with an isolated collection of all the compute, storage, networking, and security resources that they are used to. Furthermore, this virtual datacenter can grow and shrink to efficiently utilize physical resources. This is what the software-defined datacenter is all about, and it is the architecture for the cloud. Managing networks and network services to support cloud architectures is complex, time consuming and limits the achievement of full application mobility across clouds. Nicira is at the forefront of software-defined networking, which enables the dynamic creation of virtual network infrastructure and services that are completely decoupled and independent from the physical network hardware. Many industry leaders, including AT&T, DreamHost, eBay, Fidelity Investments, NTT and Rackspace are using the Nicira Network Virtualization Platform (NVP) to accelerate service delivery from weeks to minutes and dramatically reduce complexity and cost.

VMware has also announced financial results for the second quarter of 2012:

  • Revenues for the second quarter were $1.12 billion, an increase of 22% from the second quarter of 2011, and 23% measured in constant currency.
  • Operating income for the second quarter was $212 million, an increase of 13% from the second quarter of 2011. Non-GAAP operating income for the second quarter was $358 million, an increase of 23% from the second quarter of 2011.
  • Net income for the second quarter was $192 million, or $0.44 per diluted share,compared to $220 million, or $0.51 per diluted share, for the second quarter of 2011. Non-GAAP net income for the quarter was $296 million, or $0.68 per diluted share, compared to $235 million, or $0.55 per diluted share, for the second quarter of 2011.
  • Trailing twelve months operating cash flows were $2.05 billion, an increase of 33%. Trailing twelve months free cash flows were $2.01 billion, an increase of 29%.
  • Cash, cash equivalents and short-term investments were $5.3 billion and unearned revenue was $2.9 billion as of June 30, 2012.

Just one year ago this blog has started its life (see the first official post: Blog goes live).

Was a really intense year and a big challenge (more than 300 posts, with different length, but in most cases both in English and Italian), with several satisfactions. For example, I’ve tried to participate at the top virtualization blogs contents and the results where really interesting: I’ve received some votes and vInfrastructure site is 54 in the entire rank and 3rd in the Favorite New Blog list (and some mentions, included one from the Number 1)!

Also the first sponsors has arrived: I’ve choose to accept (to cover some expensive), but I still tried to keep more independence and objectivity as possible.

For the stats side, here some interesting data:

I have to be really grateful with all the people that follow my blog and hope to make better for the next year.
