Determining if an array supports automated unmap in vSphere 6.5

Many of you will be aware of the new core storage features that were introduced in vSphere 6.5. If not, you can learn about them in this recently published white paper. Without doubt, the feature that has created the most amount of interest is automated unmap (finally, I hear you say!). Now a few readers have asked about the following comment in the automated unmap section.

Automatic UNMAP is not supported on arrays with UNMAP granularity 
greater than 1MB. Auto UNMAP feature support is footnoted in the 
VMware Hardware Compatibility Guide (HCL).

So where do you find this info in the HCL? I’ll show you here.

vSphere 6.5 Core Storage White Paper Now Available

core-storageI’m delighted to announce the availability of a new vSphere 6.5 core storage white paper. The paper covers new features such as VMFS-6 enhancements, policy driven Storage I/O Control, policy driven VM Encryption, NFS and iSCSI improvements and of course new limit increases in vSphere 6.5. There are too many VMware folks to thank for putting this paper together, but you’ll find them all listed in the acknowledgements section. I do want to mention one person however; a very special thanks to Cody Hosterman of Pure Storage who spent a lot of time testing many of these new features, and providing the relevant feedback that could be included in the paper. Thanks Cody.

Photon Controller v1.1 and vSAN interoperability

PHOTON_square140Many of you will have seen the recent announcement for Photon Controller version 1.1. For me, the interesting part of this announcement is the support for vSAN as a storage platform with Photon Controller v1.1. I should think that the first question that those of you are familiar with both vSAN and Photon Controller will ask is “how do I configure vSAN for Photon Controller when there is no vCenter server in the mix?”. This is a very good question, and one which I will highlight in this blog post. There are also a few line items in the release notes which may not be very clear to those of you who are not very familiar with these products. I hope to be able to highlight these to you as well.

PowerCLI 6.5 Release 1 and vSAN

powercliThe 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 6.5 to leverage these new features of PowerCLI.

What’s new in Virtual SAN 6.5

I know that there will be a lot of information coming your way from various sources on this exact topic. Obviously, I would urge you to check out the latest and greatest documentation from our technical marketing guys for deeper detail and “how-to” guides. However, I did want to provide a brief overview of what new VSAN features are available in vSphere 6.5. Note that we also refer to this version of VSAN as 6.5.

What’s new in vSphere 6.5 Core Storage

Hello from VMworld EMEA in Barcelona. Well, we can finally talk about vSphere 6.5 today. In this post, I want to highlight a number of new and enhanced features that you will find in vSphere 6.5 related to core storage. I am not going to discuss Virtual SAN (VSAN), Virtual Volumes (VVols) or I/O Filter enhancements (VAIO) specifically in this post, although you will no doubt see some new features tie directly into the latter. Instead, I want to talk about those features that are specific to core storage.

Rubrik and VSAN webinar recording now available

Logo_Rubrik_400x400If you missed our joint Rubrik and Virtual SAN webinar earlier this week, you can now view it online. In this webinar, the indefatigable Chris Wahl, Chief Technology Evangelist from Rubrik, and myself discuss the merits of policy driven architecture, with particular focus on VSAN and of course Rubrik. The primary goal is to demonstrate the simplicity of a policy-driven approach. We hope you like it.

By the way, a joint VSAN+Rubrik white paper is still available if you would like to learn more details about both products, as well as their respective synergies.

Kudos to the Rubrik team (especially Katy) for setting this event up.
