I had someone reach out to me recently, asking for a way to change the policy on a file that was uploaded to a vSAN datastore, e.g. an ISO image. When a file is uploaded to the vSAN datastore, a VM Home namespace object is created. It is into this ‘file system’ type object that the files/ISOs are stored. Initially, I looked at ways to change the VM Home namespace. I looked at various commands to change the policy and I did find some in RVC, the Ruby vSphere Console. Unfortunately all the spbm.namespace_change commands look for a VM as…
Yesterday, we saw the announcement that VMware has release vSphere 6.7U1. This includes new releases of vCenter Server 6.7U1, ESXi 6.7U1 and of course vSAN 6.7U1. All of the hyperlinks here will take you to the release notes of that particular product. In this post, I just want to briefly run through some of the major enhancements that we have included in vSAN 6.7U1. TRIM/UNMAP Support Top of the list for me is the introduction of automated UNMAP support. Note that the key point here is that this is for in-guest space reclamation. vSAN has never had an issue with…
vSAN readers will most likely be aware that we introduced support for iSCSI on vSAN way back in vSAN 6.5. That is to say, we had the ability to create iSCSI targets and LUNs using vSAN objects, and present the LUNs to external iSCSI initiators. That release also supported Persistent Group Reservations (PGRs) but it did lack transparent failover. We followed this up with an enhancement in vSAN 6.7 which enabled transparent failover. This enabled support for features like Windows Server Failover Cluster (WSFC) to work on iSCSI on vSAN, if using shared disk mode as it uses reservations on…
The content catalog has just gone live with the schedule of break-out sessions for VMworld 2018 in Barcelona. All three sessions that I presented in Las Vegas are also scheduled for the European event. I’m fortunate that I have a chance to co-present with my good friends and colleagues, Christos Karamanolis, Duncan Epping and Paudie O’Riordan. I hope you can make it along to one of these sessions if the topic is of interest.
I’m back in the lab this week, looking at some of the newer features around vSAN. As part of this, I needed vSAN Encryption enabled, so I downloaded the latest HyTrust KeyControl appliance as this has an easy to use KMIP Server. This new version is 4.2.1, and it has a few new steps compared to the previous versions I used, which were a little confusing to begin with. First I deployed the OVA, supplied the password, logged into the web interface, and enabled KMIP as before. However, that is where things are now a little different to before.
VMworld is now officially underway, and as usual, day 1 is full of new announcements. vSAN is no exception. There have been announcements around the next release of vSAN (6.7U1), specific vSAN improvements to VMware Cloud on AWS, a Cloudera Hadoop validation on vSAN and a beta announcements. Since we’ve had quite a number of announcements, I though I would try to capture them all in one place.
It’s here. VMworld 2018 is underway. I’ve just spent a great week in Nashville, a place I have wanted to visit for the longest time. Now it’s almost time to head to the airport and catch my flight to Las Vegas. As is usual at this time of year, there are a lot of announcements and briefing requests. In this post, I am going to share some of the announcements/briefings that I have been privy to, and share some of the things (mostly in the storage space) that I plan to learn more about over the next few days.
