So vSphere 6.5 U1 PSOD bug with 10Gb Ethernet NICs has been causing some real messes for our customers for the past few weeks due to network-intensive activities such as backup over NBD or vMotion randomly triggering one. Also, last week one of our users had 2 hosts go into PSOD within 6 hours, which made him realize this bug can trigger not only from high network load, but also from creating vmkernel ports – so something you should avoid doing. They opened a support case with VMware and it appears there is now an ETA for the patch: "Performing vMotion or network related activity with vMotion/vmk add and remove tasks causing host PSOD due to a race condition is a known issue reported internally. As per Engineering team's update this is fixed in the upcoming version 6.5 Patch02 which is tentatively yet to be released in the last week of November or 1st week of December 2017". In other VMware news, the vCenter Server Appliance 6.0 Update 3c has just become generally available, adding SMBv2 support for vCenter Server Appliance to overcome SMB1 vulnerability – which means all VCSA users should consider updating soon #StopUsingSMB1 In other hypervisor news, KVM made the headlines last week with Amazon revealing its new KVM-based hypervisor – what a departure for the biggest Xen shop in the world. This made me remember someone from Veeam jokingly noting just a few weeks ago how Xen developers spent the last few years writing roadmaps, while KVM developers spent the same time writing code. This is certainly the best PR KVM could ever wished for, and it comes at the right time of growing concerns with VMware as the vendor (at least in the enterprise space, this has been a big theme in many of my recent client conversations), and with the new Microsoft having their head up in the cloud - which probably means that down the road, we will see Hyper-V only getting features that are important for Azure and Azure Stack. However, personally I don't see KVM presenting any significant threat to the leading hypervisors any time soon for a simple reason – it needs solid management layer before it can be successful in any market. In simple words, there's no "vCenter for KVM" available today – just a few point solutions which are rather exceptions proving the issue. Proxmox is a great tool for SMB only; Nutanix AHV does not support deployment into the existing, "classic" (non-HCI) infrastructures; and of course there's OpenStack – flexible and powerful solution for those few with an army of developers on staff. So, the issue with KVM is currently not with the hypervisor itself, and there's a huge opportunity to make it wildly successful even in its current state (as Nutanix already proved) – any ISV who decides to take up on this task has all the chances to become the next VMware, albeit in the shrinking "on-prem data center" market. Speaking of which, HPE Is Exiting the Cloud Server Business – meaning it will no longer sell low-end "commodity" servers to large cloud computing shops. Indeed, those companies are big enough to go directly to server manufacturers, so this decision makes sense – but with them setting the precedent, we may perhaps soon see larger enterprise shops starting to do the same? While on the low end, things are shaking as well... seeing vendors like SuperMicro redefining what margins on hardware can be, and with the public cloud adoption skyrocketing – those leading commodity server vendors may have really tough times ahead. So, iPhone X has been finally launched and everyone writes exciting reviews on its animojis. When I was a kid, I thought the future will be about flying cars and space expeditions – now I am almost 40 and it's quite sad that the future has arrived in the form of animated sh*t... oh well, life is life. As you know, I myself am an Android user – but of course I have plenty of i-devices belonging to my family members around the house. And if there was one thing I could ask Apple to deliver instead of FaceID and other "amazing advancements" in iPhone X – that would be a power cable that does not tear apart after a few months of usage. Really Apple, how hard could that be? |
