The continued rise of HCI, and especially vSAN

This morning, twitter is alive with VMware’s Q4 2016 results. In a nutshell, its been a phenomenal quarter. Of course, the first thing I wanted to check out was how vSAN did. “Outstanding” is the word. At VMworld 2016 in Barcelona, we were somewhere around 5,500 vSAN customers. Today, that number stands at 7,000. In the space of a year we have more than doubled the number of vSAN customers globally. There is no doubt about it, but Hyper-Convergence is hot. The recent acquisition of SimpliVity by HPE demonstrates this. [Update] As does NetApp’s intention of getting into the HCI…

New vSAN Management Pack for vRealize Operations

Last month we announced the release of a new vROps Management Pack specifically for vSAN. Previously the vSAN Management Pack was bundled with the MPSD – Management Pack for Storage Devices. I wrote about this when it entered beta, way back in 2015. Well, for those customers who are only interested in monitoring vSAN, and didn’t want all the other parts of the MPSD, the new vSAN Management Pack is now a stand-alone offering, so no MPSD required. This new vSAN Management Pack focuses on 3 main areas of vSAN: (1) Health and Availability, (2) Performance Analysis and (3) Capacity…

vSAN Stretched Cluster – Partition behavior changes

My good pal Paudie and I are back in full customer[0] mode these past few weeks, testing out lots of new and upcoming features in future release of vSAN. Our testing led us to building a new vSAN stretched cluster, with 5 nodes on the preferred site, 5 nodes on the secondary site, and of course the obligatory witness node. Now, it had been a while since we put vSAN stretched cluster through its paces. The last time was the vSAN 6.1 release, which led us to create some additional sections on stretched cluster for the vSAN Proof Of Concept…

Gathering core dump files when encryption is enabled

One of the key new features of vSphere 6.5 is vSphere VM Encryption, a mechanism to encrypt all virtual machine files. This mechanism not only encrypts the VMDK, but also the metadata files and core dumps associated with a VM. Now, there would not be much point in sending an encrypted core dump file to VMware for analysis, so a mechanism has been put in place to allow these files to be recrypted using a password before sending them to VMware. The password can then be shared with VMware to allow us to examine the core dumps.  This is how…

Extending an ESXi diagnostic core dump partition on a vSAN 6.5 node

This is something very interesting which gained support with the release of vSAN 6.5. It will be of interest to those customers who boot their ESXi hosts from USB/SD devices, and also have vSAN configured. One long-standing restriction with this configuration was the inability to boot from USB/SD when the amount of memory in the host is over 512GB. This is because we could not guarantee that the memory dump would fit in the pre-sized core dump partition. Well, now we have the ability to resize the core dump partition, even when it resides on a USB/SD device. The guidance…

Virtually Speaking Podcast Episode #34 – Core Storage

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.
