VMware has just announced the release of vSphere 6.5 p01 (Patch ESXi-6.5.0-20170304001-standard). While there are a number of different issues addressed in the patch, there is one in particular that I wanted to bring to your attention. Automated UNMAP is a feature that we introduced in vSphere 6.5. This patch contains a fix for some odd behaviour seen with the new Automated UNMAP feature. The issue has only been observed with certain Guest OS, certain filesystems, and a certain block sizes format. KB article 2148987 for the patch describes it as follows: Tools in guest operating system might send unmap…
Last week during a visit to VMware headquarters in Palo Alto, I had the opportunity to catch up with our engineering team who are responsible for developing storage solutions for Docker and Kubernetes running on vSphere. I have written about our Docker volume driver for vSphere and Kubernetes on vSphere already, but it’s been a while since I caught up with the team, and obviously more and more enhancements are being added all the time. I thought it might be useful to share the improvements with you here. There also seems to be some concerns raised about the availability of…
Many readers will be aware that John Nicholson and Pete Fletcha of the VMware Storage and Availability Tech Marketing team run a weekly podcast show called Virtually Speaking. This week I am back as a guest on their show, alongside Cody Hosterman of Pure Storage. We discuss a lot of the new core storage features in vSphere 6.5, which were detailed in a co-produced white paper that we recently created. You can read about how to get the white paper here. You can listen to the podcast through the player below. I hope you enjoy it.
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…
I’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…
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.
A short post to let you know about some upcoming speaking engagements that I am doing over the next couple of weeks. First up, I will be speaking at the TechUG, or Technology User Group event next week. This event will be held on Thursday, November 26th. It will be held in the Westin Hotel in the heart of Dublin city, Ireland. There is a really good agenda for this event (which is not a VMware centric event), that you can find at this link here. I personally will be speaking about Virtual SAN (VSAN), VMware’s hyper-converged compute and storage…
