Considering VSAN

Chuck's Blog - EMC

Although VSAN does many of things a traditional storage array does, it''s not a traditional storage array: it''s a software-based storage array that uses clusters of commodity server hardware to do its work.    The comparison here is a modest three-node cluster supporting 288 VMs.  

VSAN, VSAs and External Arrays

and are basically run like dedicated storage, except using off-the-shelf hardware. VSAs have the obvious advantage of running on most anything, which is especially convenient if you have unused (or underused) hardware on hand.

The Problem With Storage Swiss' Analysis -- On VSAN

Chuck's Blog - EMC

  By comparison, most storage professionals look at the world through an established lens, so -- in general -- it takes them a few ticks longer to appreciate what VSAN is all about. Let''s not forget the obvious comparison with external storage arrays -- it sort of works the same way. 

Five Reasons Why VSAN Is Different

Chuck's Blog - EMC

But I’ve been dismayed to see industry commentary where VSAN gets arbitrarily lumped in with either (a) a gaggle of software-based storage products, or (b) some of the newer software-clothed-in-hardware products.

When Cloud Grew Up

Chuck's Blog - EMC

By comparison, both AWS and Azure don't have much to say in the enterprise application category, which I would argue puts them at a strategic disadvantage. By comparison, AWS is nowhere to be seen in this all-important on-premises operational compatibility discussion.

and are basically run like dedicated storage, except using off-the-shelf hardware. VSAs have the obvious advantage of running on most anything, which is especially convenient if you have unused (or underused) hardware on hand.  Parts is parts, although pricing on server hardware is generally much more transparent than larger array hardware. Most often, you can take your VSA licenses to new hardware, new hypervisor, etc.

IBM And VMware Tie Up: What Does It Mean?

Chuck's Blog - EMC

  The offering will be comprised of commodity hardware (low margin), VMware software products (margin goes to VMware), and IBM's value-added service delivery.  Can these customers take their licenses to IBM's cloud, or do they have to buy again?

Servers/Hardware. Speaking of Pulumi, Kyle Galbraith wrote up a comparison of Pulumi and Terraform for infrastructure as code. These look interesting, but be aware that they are not licensed with an open source license. Additionally, the wording of the license for these extensions has caused some consternation (at least, among the folks I follow on Twitter). Welcome to Technology Short Take #114!

Pluggable Databases Vs. Database Virtualization - Chuck's Blog

Chuck's Blog - EMC

  New functionality inevitably means new licensing terms, which isn't expected to be cheap -- unless there is a viable competitor in the market gnawing away at market share.  Once again, these are only theoretical comparisons.  Chucks Blog.

Servers/Hardware. Kevin Houston’s March 2015 blade server comparisons might be a useful place to start. Yes, you could run Docker on bare metal and achieve (the author’s words) “massive CapEx benefits” by “eliminating expensive licensing” for VMware. Welcome to Technology Short Take #50, the latest in my series of posts sharing various links and articles pertaining to key data center technologies. I hope that you find something useful here!
