PowerCLI 6.5 Release 1 and vSAN

The first email I saw this morning in my inbox was from my good pal, Alan Renouf. Alan is our product line manager for APIs, SDKs, CLIs and Automation Frameworks (congrats on the promotion Alan). Anyway, Alan was announcing the General Availability of VMware vSphere PowerCLI 6.5 Release 1. There are a whole bunch of improvements in this release, and much kudos must go to the PowerCLI team. However from a vSAN perspective, things look really cool. [Update] This version of PowerCLI also works with vSAN 6.2 and 6.0, so there is no need for customers to upgrade to vSAN…

Can Storage Policies be used with VIC?

The answer is an emphatic yes. One can absolutely use storage policies with vSphere Integrated Containers (VIC). However, there is currently no way to specify a policy at the docker CLI when creating a container (at this time). Therefore one would have to deploy the VCH, then deploy the container, and then finally modify the storage policy as appropriate. My understanding is that consideration is being given to a way to do this at deployment time, but at the present, it involves a number of steps. Let’s discuss them in turn.

Compare and Contrast – VSAN and VVols

Earlier this month I had the opportunity to meet with a number of VMware customers in both Singapore and in the UAE. Most of the sessions were enablement and education type sessions, where there was a lot of white-boarding of VSAN (VMware’s hyper-converged infrastructure product) and Virtual Volumes (VVols – Software Defined Storage or SDS for the storage arrays). This wasn’t a sales session; I’m not in sales. The objective of these sessions was simply to educate. I guess when you are immersed in this stuff 24×7, it easy to fall into the trap of believing that everyone is well…

The value of Virtual Volumes (VVols)

Regular readers will know that I normally blog about the technical aspects of storage, as opposed to doing opinion pieces. However there have been a number of articles published recently questioning the value of VMware’s Virtual Volumes, commonly referred to as VVols. In general, the pieces I have read ask whether or not VVols (or to be more accurate, per-VM granularity feature of VVols) adds value when NFS is already doing per-VM granularity in the form of files. The point that was missed in these pieces is that VVols is so much more than per-VM granularity. I’ve just come back…

PowerCLI 5.8 Release 1 – new SPBM cmdlets

Yesterday saw the release of vCloud Suite 5.8. While there are quite a few new enhancements to the VMware product line in this release, what really jumped out at me were the new PowerCLI cmdlets for Storage Policy Based Management (SPBM). SPBM is a critical component of VIrtual SAN (VSAN), and will play a major role in the Virtual Volumes (VVols) feature which has been tech previewed at VMworld 2014. VVols will enable our storage array partners to implement out Software Defined Storage vision –  you can read more about there. So what are the new cmdlets for PowerCLI in…
