In my day to day jobby, I manage multiple Hyper-V clusters, and these clusters use shared storage. Most of the storage is a JBOD shelf with dual SAS connections to the hypervisor nodes. Because the shelf is JBOD, Windows is the brains for the storage. Enter Windows Storage Spaces. This is basically a Software RAID that you configure a pool of disks, and then you layer a VHD over that pool. After a volume is created on the VHD, it can be used by the hosts. These volumes can be added to Cluster Shared Volumes which allows the volume to move between host nodes, creating redundancy. All the VMs hosted in the cluster, live on the CSV, making them Highly Available.

I work with HPE Systems almost exclusively, and as of late I have been getting very irritated with the browser warning about the self signed SSL cert that is installed on the HPE iLO by default.

I have been 3D printing for about a year now, its had its ups and downs, good times and bad. Some times its the greatest thing, and sometimes I’m glad I don’t keep a baseball bat near my 3D Printer, because I may not still be the owner of one if I did. I know all printers are different and everyone has their reasons for why or what they do and use for the build surface. I have the Ender3, its a great entry level printer for the price and I have spit out some amazing prints. But one the most notorious issues with the Ender3 is the warped bed. It seems like everyone has reported this issue. And I think one thing all 3D Printer Hobbyist could agree on, is the first layer is one of the most important parts of the print. And when you printing around .2mm layer hight, if the build surface isn’t perfect you’re going to have problems, especially with larger prints.
