Remember how I promised to get back to you about a certain Super Secret Awesomesauce Company? In particular, the Super Secret Awesomesauce Company has me so excited that I want to shout it off the rooftops, but I’m afraid I can’t, at least not just yet. Check back on the 19th of August, and you might be in for a very cool surprise. Joep Piscaer, ‘Tech Field Day Extra (#EVMWU14) at VMworld 2014: check!‘ Well, here goes. …

Update on SMI-S provider causing latency issues

Update on SMI-S provider causing latency issues

In a previous post called Running a Dell PERC with high latency? Check the LSI SMI-S vib!, I mentioned that having the LSI SMI-S provider installed on a host causes significant latency issues on an ESXi-host. I’ve been having a lot of latency issues lately with two Dell PowerEdge R310s. These 1U boxes have a low end controller, an PERC H200. I’ve been having latency spikes in the range of 500-600ms, which is high enough to have the Linux …

VMworld 2014: DevOps, SDN and ITaaS Clouds

VMworld 2014: DevOps, SDN and ITaaS Clouds

The good folks over at VMware’s Community program have assigned me a bloggers pass to attend VMworld 2014 in San Francisco. I’m planning a full week with a mix of keynotes, technical break-out sessions and a lot of community hang time. This year’s VMworld will again feature blogger tables at the community booth in the hang space, big screens to follow the keynotes and enough room to spend some time with the Community Social Media team. As in earlier …

Tech Field Day Extra (#EVMWU14) at VMworld 2014: check!

I am very pleased to announce that I’ll once again be part of the fantastic Tech Field Day event series during VMworld 2014 in San Francisco. I have previously participated in Tech Field Day Extra at VMworld US 2013 and Storage Field Day 4, and this month I’ll attend the Extra at VMworld US 2014, too. These events are very interesting for me as a delegate, because I can directly interact with the top technical dogs from the presenting companies and …

Attend VeeamON, because community

Attend VeeamON, because community

In the pre-VMworld buzz, it’s not hard to forget other virtualization-related conferences. VeeamON, however, is a new kid on the block, and I have high expectations for this conference. Why attend VeeamON? I tend to choose to attend conferences based on the ‘community’ aspect of the conference. Does the event attract a big virtualization community, does it have community events and gatherings (parties, white boarding sessions, blogger space, stuff like vBrownBag and of course User …

Separate ISO datastore and VSAN? Use Veeam vPower NFS!

Separate ISO datastore and VSAN? Use Veeam vPower NFS!

Recently, I have had a design challenge for my non-profit unmanaged VPS hosting project, klauwd.com. The challenge basically comes down to offering ISO files to the platform’s tenants. In earlier design iterations, I’ve always had a separate datastore on shared storage with separate tenant rights assigned to the datastore. I’ve used products like Nexenta, FreeNAS and HP StoreVirtual (LeftHand OS) virtual appliances to transform local storage to shared storage and carve up multiple datastore from there. This has worked …

Running a Dell PERC with high latency?  Check the LSI SMI-S vib!

I’ve been having a lot of latency issues lately with two Dell PowerEdge R310s. These 1U boxes have a low end controller, an PERC H200. I’ve been having latency spikes in the range of 500-600ms, which is high enough to have the Linux VMs remount their filesystems in read-only mode continuously. This basically happens any time any of the VMs does moderate (say, 25+) iops, and causes the controller to lock up and take down multiple other VMs along the …

Can’t delete a Nutanix datastore?

Can’t delete a Nutanix datastore?

During some performance and configuration testing of a Nutanix cluster, I came across an issue where I couldn’t delete a Nutanix datastore (container) from the cluster. I could successfully unmount it from all hosts in the cluster, but I couldn’t actually delete it. Now, you won’t run into this issue very often, but a clear case where you would is when performing the Nutanix Diagnostics test. This test involves creating a container, mounting it on …

Nutanix and Dell to team up to deliver the new XC-series appliances

So remember when I talked about Nutanix going into the software-only market? Today, they’re taking another step in that direction by signing an OEM deal with Dell. Not only are they combining technical powers (running Dell PowerEdge hardware with the Nutanix secret software sauce on top), they’re also joining forces in “sales, marketing, support and service investments, as well as alignment of product roadmaps“. I think this is very smart for both parties, since Nutanix can leverage …
