One OpenStack to Rule Them All: Bare Metal to Clouds

At VMworld 2014, VMware announced its easy-to-install OpenStack distribution, VMware Integrated OpenStack. This got me thinking, as normally OpenStack refers not just to the OpenStack distribution but to a specific underlying hypervisor as well, usually KVM. However, we know that OpenStack works equally well on KVM, vSphere, Hyper-V, and Xen, as it is more of a cloud management layer than a hypervisor. We should probably never lose sight of that little aspect of OpenStack: it is not a hypervisor. As an open-source management stack, it is possible for it to manage cross-hypervisor with a few modifications to its components.

Remote Office Two Server High Availability Discussion At..

At VMworld2014, Michael McDonnell from Walgreens and Rick Terlep, a Sr. Systems Engineer and End-User Computing Partner Advisor at VMware, presented to approximately 5,000 session attendees regarding the reference architecture Michael designed for Walgreens’ 8600 stores. Ease of deployment and maintenance were key factors in the three-year old design. As part of the deployment, Walgreens chose a converged solution. In the session VMware also announced the release of two new vSphere editions, vSphere Remote Office Branch Office Standard and Advanced. As with all vSphere editions, high-availability requires shared storage, either in the form of an external storage array or SAN, or in the form of a software-only Server SAN.

Can Storage Enable Hyper-V to Replace VMware?

In our recent webinar “Don’t let storage eat your Hyper-V Savings” we were asked a question from the audience, “Will Hyper-V ever replace VMware as the predominant hypervisor in the data center?” This loaded question is actually very interesting. While each has unique features VMware probably has the overall lead in that area, and of course, has an unprecedented lead in terms of market share. The appeal of Hyper-V is that it can be much more affordable than VMware and seems to be narrowing the gap in features. Can Storage Give Hyper-V The Advantage Over VMware? A more interesting twist on the above question is “Can storage give Hyper-V an advantage?” Microsoft provides lower level access and allows for more interesting configurations than does VMware. Three examples come from Gridstore, StarWind Software and Violin Memory Systems. Each of these address Hyper-V storage differently, but each can potentially broaden Hyper-V’s appeal.

Hyper-V Software-Defined Storage

During a recent Storage Switzerland webinar, the audience was asked what their plans were for implementing Hyper-V into their environment. 50% of the respondents stated that they plan to exclusively deploy Hyper-V into their data center while another 25% responded that they intend to run a mixed Hyper-V and VMware infrastructure.

Server-Side, Converged Storage vs. Shared Storage

As I discussed at a recent event and covered in one of our top-read articles, “How Will Storage Controller Technology Evolve in 2014?“, this may be a year of significant change in the way we architect storage. There are three things driving this change. The first is the rise of the Hypervisor (VMware, Hyper-V, Xen, KVM, etc…). The second is the seemingly endless supply of CPU power that allows virtualization to work. And the third is the widespread availability of Flash SSD. These three factors are forcing legacy storage architectures to dramatically change while enabling improved storage architectures to emerge.
