In part one of Cost to Build a New Virtualized Data Center, we discussed the basic software costs for a virtualized data center based on VMware vSphere 6.0, Citrix XenServer 6.5, Microsoft Hyper-V 2012 R2 and 2016, and Red Hat. If you missed that, please click here to review before continuing.

DAS Is Dead; Long Live DAS!
In a play on the old saying “the king is dead; long live the king!” this post will opine about the current resurgence of locally attached storage in the data center.
Security Questions from VMworld 2013
While at VMworld 2013, I started to ask 5 security questions that have been bothering me for some time now. Some of these questions apparently have no answers currently and others only have operational answers, no technology. Security of a secure hybrid cloud is a mix of procedures, policies, operations, and technology. These questions are about various aspects of virtual and cloud environments that have been nagging at me for some time now as well as problems I have faced managing our own cloud instances. Perhaps you have questions you would like to add to the list, if so please share.
Three Things To Consider About Virtual Storage Appliances
Virtual storage appliances offer great features, flexibility, and pricing, but like most new technology they need us to ask our vendors different questions.
What is the Future of Virtual Storage in a Software Defined Data Center?
What is the future of virtual storage in a Software Defined Data Center (SDDC)? As more and more technology gets moved from hardware to software in the SDDC, I have to wonder which direction virtual storage will go.
If we use networking as an example, the technology has evolved from setting up local virtual switches on each of the hosts to a virtual distributed switch (VDS) model where all the individual host-level virtual switches are abstracted into a single large VDS that spans multiple hosts at the Datacenter level. In this design, the data plane remains local to each VDS, but the management plane is centralized with VMware vCenter Server acting as the control point for all configured VDS instances.
Hard Disk Drives (HDD) for virtual environments (Part I)
Unless you are one of the few who have gone all solid-state devices (SSDs) for your virtual environment, hard disk drives (HHDs) still have a role. That role might be for primary storage of your VMs and/or their data, or as a destination target for backups, snapshots, archiving or as a work and scratch area. Or perhaps you have some HDDs as part of a virtual storage appliance (VSA), storage virtualization, virtual storage or storage hypervisor configuration. Even if you have gone all SSD for your primary storage, you might be using disk as a target for backups complimenting or replacing tape and clouds. On the other hand, maybe you have a mix of HDD and SSD for production, what are you doing with your test, development or lab systems, both at work and at home.
