"description":"SSI SCHAEFER has developed its own warm-standby system to meet the customer’s requirements of high IT security and minimal operational restrictions. Originally, a redundant arrangement of external SAN storage solutions was envisaged. This, however, requires expensive HW and its separate network, which cause additional maintenance. Since May 2018 though, DRBD®, Linbit’s OSS, has been SSI SCHAEFER’s preferred solution for systems with a storage requirement of up to several terabytes. Easy to implement, remotely controllable and without expensive SAN hardware DRBD® allows operating highly available databases.",
"description":"WEDOS’ former setup was based on PXE(LTSP) and Kubernetes and provided a fully automated environment. Overall, the system worked well. The best I/O results were seen with BeeGFS providing large shared drivers around the environment. However, due to unknown circumstances, the blades of the system rebooted randomly. . A mixture of upset customers and time consuming resynchronization demanded an urgent change of storage technology for the company. At first, WEDOS set up a DRBD® orchestration with iSCSI on their own, but then learned there was a much easier and much faster solution: LINSTOR®. WEDOS tested this thoroughly, and after yielding wonderful results, they now use LINSTOR for Kubernetes and OpenNebula. With LINSTOR, the use of ThinLVM and DRBD is simple",
