vSphere Client timeout after replacing Machine…

The last few days I have been troubleshooting a very strange issue with the C# vSphere client on a new vSphere 6.0 install for a customer. The vSphere Client was initially working fine, until I replaced the Machine SSL Certificate for vCenter. After the Machine SSL Certificate was replaced, the vSphere client would timeout on connection. The issue was only connecting to vCenter, if connecting the vSphere client directly to hosts the client worked fine.

#VMware Horizon View 7: Instant Clone Desktop Pool [Part 8]

VMware Horizon View 7: Instant Clone Desktop…

In Part 8 of this Boring series I will be setting up an Instant Clone Desktop Pool. This is one of the coolest features announced of Horizon 7 in my opinion! You may have heard of Project Fargo (aka vmFork) announced during the keynote speech of VMworld 2014. This is the result of that project! Instant Clone gives you the ability to rapidly deploy VMs (children) from a already powered on and running VM (parent). The child clones share the memory and disk of the parent for Reads while Writes are placed in a delta disk. To read more about Instant Clone technology check out this VMware Blog post.

VMware Logon Monitor logs a wide array of metrics related to logon, group policy, user profile, and performance. These metrics were selected to provide administrators a detailed view of end user systems during logon time so performance bottlenecks may be more easily root caused.

Micro-Segmentation, the right way.

Last week we attended the Check Point CPX2016 conference in Chicago. We talked to a lot of interesting people including network administrators, security team members & CISOs, each one with his or her own story and pain points. We’ve had fascinating conversations, about floating data centers, securing law firm applications and the usual woes of developers on security teams (and the other way around).

VMware NSX Security Features – Who should pay…

One of the typical questions when considering NSX deployments is who should be the administrator? However this is typically a two horse race, between Network and Virtualization Systems Administrators. Although NSX is SDN (software defined networking) the driver behind much of what it does is due security requirements, using vlans to segregate layer two networks, firewalls and vpns are examples of security driven network features.

The rigorous process of following a VMware Validated Design (V2D) to build a Business Critical Applications (BCA) database architecture was made more interesting by focusing on Virtual SAN and NSX on Quanta Hardware with Intel SSDs. On this All-Flash architecture, we chose to run the Oracle RDBMS version 12c under high workload using the formidable workload generator known as the “Silly Little Oracle Benchmark” or “SLOB”. Six compute nodes were concurrently loaded with the SLOB tool which generated an extreme workload that would be highly uncommon in any practical customer environment. The details are available in the full report linked below, but it should be noted that at 200k IOPS the read latency averaged 5ms. This was truly a BCA…Read More
