I have now been on a steady diet of hyperconverged customer conversations for the last six months. That's my nature -- I learn about something by talking to the people who are actually doing it ...
With all due respect to industry analysts, I’ve now been able to create a fairly accurate model of what most people are looking for — and it’s not exactly the picture that the analysts are painting.
Sampling bias aside, I’m finding that the more I talk to people, the more the observed customer shopping lists tend to converge into a very short, understandable agenda.
Keep in mind, the hyperconverged segment is moving fast, with many players and interesting choices. What was new and innovative a few years ago is simply table stakes today.
There’s now been enough real-world experiences that there are more than a few fully-informed buyers out there. And they certainly have strong opinions! Continue reading
It's time expand and showcase the strength of software-defined storage at the upcoming OpenStack Summit. Take a look at the abstract of the session I'm scheduled to participate as a speaker and lets' get that bad boy vote in and into the schedule.
Getting the Bang for your Buck with Software-Defined Storage in OpenStack
OpenStack has become the standard infrastructure consumption layer for a variety of applications. These applications have different storage requirements and being able to provide a storage solution that matches these requirements is critical to ensure the adoption of OpenStack as the cloud platform of choice across a wide array of applications.
It is also important that enterprises that have made significant investments in storage gear are able to leverage those investments for their OpenStack deployments, while still having the choice of integrating newer storage technologies such as hyper-converged storage as they progress forward in their OpenStack journey.
This session will highlight how software-defined storage can enable enterprises to leverage their existing storage investments in building their OpenStack clouds and allow them to add newer technologies such as Virtual SAN as they go forward. The session will include
- How to use policy driven storage to mix and match traditional SAN and newer hyper-converged storage for providing storage with different SLAs
- Simplifying management and operation of a storage solution for OpenStack instances and volumes
- Demo of a vSphere based software defined storage solution providing multi tier storage (SAN, Virtual SAN, NFS, etc) for OpenStack workloads.
Take a minute and please vote.
VOTE! for session here: Getting the Bang for your buck with Software-Defined Storage in OpenStack

The VMware Virtual SAN Assessment Tool is now generally available!!!!
The Virtual SAN Assessment Tool is a usability and manageability tool that is available to the public free of charge. VMware is providing access to this solution using a software-as-a-service (SaaS) model that is accessible for any new or existing customers interested in Virtual SAN. The tool is designed to provide customers a simple one-stop shop solution for all things related to the assessments of Virtual SAN.
The Virtual SAN Assessment Tool is based on two components, and together they provide data collection and presentation in the form metrics visualization.
- Virtual SAN Assessment Tool Portal - is a public web application that receives the I/O traces from customers infrastructures and presents the detailed results. It also provides the ability to export the results onto different document types excel, powerpoint, etc.
- Virtual SAN Assessment Tool Collector - is a virtual appliance (OVF file) deployed in customer environment that collects data and sends it to the portal. The appliance is configured with 4 vCPUs / 8 gb ram / 200 gb disk space, and it introduces a low of overhead while collecting data.

10 Things You Need to Know About VSAN
VMware Virtual SAN fundamentally changes the way vSphere admins do storage. While there are several items of great material, this blog post covers the bare essentials for busy IT professionals.
The Collapse of Storage
The storage industry is undergoing rapid structural change that has not been seen in decades. Going forward, everything we’ve come to know about storage will be changing. Chuck Hollis takes a closer look at what this means.

From the early days of VMware, it became clear that dealing with storage in efficient and scalable ways were key requirements for the success of virtualization in enterprise environments. Indeed, the storage stack of ESXi, including VMFS, played a key role in the proliferation of virtualization in data centers, where data is stored and managed by high-end disk arrays. Based on those foundations of storage virtualization, over the years, VMware introduced a range of availability and data management solutions ranging from HA, DRS and FT to Disaster Recovery and Data Protection. Moreover, VMware encouraged and supported a vast ecosystem of partners who innovated on the vSphere platform. See for example, the VADP ecosystem and more recently Virtual Volumes and VAIO I/O Filters.
For those of you have been following this thread for a while, you know we’re in the midst of head-to-head performance testing on two identical clusters: one running VSAN, the other running Nutanix. Recently, we’ve updated the Nutanix cluster to vSphere 6 and 4.1.3 — however, no differences have been observed performance since the change.
Up to now, we’ve only been able to share our VSAN results. That's because Nutanix recently changed their EULA to prohibit any publishing of any testing by anyone. It's very hard to find any sort of reasonable Nutanix performance information as a result. That's unfortunate.
By comparison, VMware not only regularly publishes the results of our own tests, but also frequently approves such publication by others, once we’ve had a chance to review the methodology -- simply by submitting to firstname.lastname@example.org.
Since the results are so interesting, we're continuing to test!
As we start to move from synthetic workloads to specific application workloads, we recently finished a series of head-to-head Jetstress testing against our two identical clusters. Previous results can be found here and here.
If you’re not familiar, Jetstress is a popular Microsoft tool for testing the storage performance of Exchange clusters. A busy Exchange environment can present a demanding IO profile to a storage subsystem, so it’s an important tool in the testing arsenal.
TL:DR our basic 4-node VSAN configuration passed 1000 heavy Exchange users with flying colors — and with ample performance to spare. We can’t share with you how the identical Nutanix cluster did, but it’s certainly a worthwhile test if you have the time and inclinations.
That being said, there were no surprises — each product performed (or didn't perform) as we would expect based on both prior testing as well as customer anecdotes.
Now, on to the details!
Duncan Epping brings us a great VSAN story today -- a very early VSAN adopter who now is intent on replacing as much of their existing storage environment as possible with VSAN.
For United Utilities, it's a perfect storm of lower cost, amazing performance and a simplified operational model. All future storage requirements are going on VSAN unless there's a really good reason not to.
But it's not as easy as it sounds, as there are predictable organizational issues at hand
A great read!
