  • Please stop stretching your VLANs, virtualize your network

    Published August 9, 2016 by -- 3 Comments

    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 t ...

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 [ … ]
