vRealize Log Insight internal storage management
Recently I encountered a alert in vRealize Operations stating that on one of my virtual machines the disks-ace was getting low. It turned out to be the vRealize Log Insight server in my test environment. For those of you that don’t know, vRealize Log Insight is a highly scalable log management solution which can collect all log information in your environment and analyse and present this in intuitive, actionable dashboards and sophisticated analytics. Browsing through the vRealize Log Insight interface I could not find any settings regarding retention times, garbage collection intervals, history settings or any techniques to limit the amount of [ … ]
Three Dimensions of Storage Sizing & Design – Part 4: Throughput
In this fourth post of the multi-post Three Dimensions of Storage Sizing & Design we will dive deeper in the dimension: Use and specifically the application Workloads part characteristic Throughput. Depending on the application workload requirements, you will need to size the storage system for Bandwidth. So let us dive deeper into MB/s. What is Throughput? Throughput – measured in Megabytes per second, defines the data transfer rate. Often this is also called bandwidth, but there is a distinct difference between throughput and bandwidth. Bandwidth is the raw capability of a channel to move data through that [ … ]
VMWorld 2016 Europe Must-See Sessions
VMworld 2016 US is well on it’s way. For those of you who have missed the live stream of the keynote, here’s the recording (about 1 hour 20 minutes). One of the key topics is Cross-Cloud Services. Moving your workloads around in different clouds to enable your customers/users/clients to access their apps and data quickly and as resilient as possible. Other hot topics include VSAN and NSX. If you have not already looked at the technology and products, VMworld is the place to do so and to speak with people who have already gone through the move to [ … ]
VMware announces Cross-Cloud Architecture
Companies are increasingly relying on multiple public and private clouds to run their applications, but are daunted by the challenge of managing and securing applications across diverse cloud platforms. When customers combine a best-in-class private cloud with leading public clouds they have the strongest, most flexible hybrid cloud strategy. At VMworld VMware announced the Tech-Preview of their Cross-Cloud Architecture which delivers cloud freedom and control by providing a common operating environment for all clouds. VMware Cross-Cloud Architecture builds on its leading private and hybrid cloud capabilities by offering customers the freedom to innovate in multiple clouds, and is delivered through VMware [ … ]
VMware presents Cloud Foundation
With the Software-Defined Data Center (SDDC), VMware laid out the vision for the architecture of the hybrid cloud. In an SDDC, compute, storage, and networking services are decoupled from underlying hardware infrastructure and abstracted into logical pools of resources that can be more flexibly provisioned and managed. VMware wants to bring customers a standardized SDDC environment with VMware Cloud Foundation. VMware Cloud Foundation is the next step and greatly simplifies private and hybrid cloud development. It is a unified software-defined data center platform that integrates VMware compute, storage, and network virtualization and automates the installation, update, and lifecycle management of private [ … ]
NSX security group misconfiguration
Recently I ran into an issue in which the tenant was not able to connect to its virtual machine from their office network. The tenant environment sits on an infrastructure build with VMware NSX and the vRealize suite. Now the solution to this problem wasn’t really rocket science, but since I am fairly new to NSX and had written down the situation, I thought why not share it here as well. The situation When I received the call the only thing that was mentioned was that tenant was unable to make a connection to the virtual machine using any service. But first things [ … ]
You want micro-segmentation? vRealize Network Insight is your friend!
As many of you have probably heard, in June 2016 VMware acquired Arkin Net. Arkin Net offers 360 degree visibility, enables faster deployments via micro-segmentation planning, and delivers significantly lower time to resources, leveraging constructs like ‘time machine’, natural language search, and contextual analytics. Now 2 months later the impact and position is visible, VMware will be incorporating Arkin Net with its vRealize Cloud Management platform. Under its new name, vRealize Network Insight, VMware vRealize Suite will have the ability to extend across the entire SDDC, including the VMware NSX network virtualization layer. vRealize Network Insight vRealize Network Insight has three [ … ]
Please stop stretching your VLANs, virtualize your network
Network admins hate stretching VLANs across data centers, we absolutely hate it. It causes potential instability on a inter-data center scope, destroys our isolated fault domains; something happens with VLAN X on site A, it also can take down site B (unless you take special precautions). I spent a few hours last week and the week before to help out customers that had that exact issue, which triggered this post. The entire idea of stretching VLANs between data centers is about virtual machine mobility. You can do a failover between sites and don’t have to make adjustments to your applications [ … ]

Three Dimensions of Storage Sizing & Design – Part 3: Speed
In this third post of the multi-post Three Dimensions of Storage Sizing & Design we will dive deeper in the dimension: Use and specifically the application Workloads part characteristic Speed. Depending on the application workload requirements, you will need to size the storage system for The Need for Speed. So let us dive deeper into IOPS. Speed with computer storage devices like hard disk drives (HDD), Solid State Drives (SSD) and Storage Area Networks (SAN) is expressed in Input/Output Per Second (IOPS). Applications will interact with storage for retrieving and storing data. What [ … ]
