How to integrate MinIO with LINSTOR to distribute data on Kubernetes

While LINSTOR is on the way to becoming an industry standard as software defined block storage, MinIO stands out as the number one product in the object storage world. LINBIT has been working in integration with MinIO for a long time and has signed infrastructures that can be used safely in business solutions. The biggest […]

Using DRBD block devices for kubevirt

This demonstrates how to use DRBD block devices provisioned by the LINSTOR CSI driver. We assume that the CSI driver is working (e.g., by installing it via it operator/helm chart), and that kubevirt also works and that live migration is enabled and tested. Live migration is not a requirement, but it a lot more fun. […]

Booting diskless Windows clients via WinDRBD

Those who wonder what we’ve done since posting the previous blog article on WinDRBD will be interested to hear that we have been working hard to get Windows to boot over a WinDRBD device. The remote DRBD device can be hosted on a Linux machine which makes advanced features, such as fine-grained snapshots, readily available […]

IOPS World Record Broken – LINBIT Tops 14.8 million IOPS

In a performance test LINBIT measured 14.8 million IOPS on a 12 node cluster built from standard off-the-shelf Intel servers. This is the highest storage performance reached by a hyper-converged system on the market, for this hardware basis. Even a small LINBIT storage system can provide millions of IOPS at latencies of a fraction of […]

Optimizing DRBD for Persistent Memory

Persistent Memory (PMEM) is an exciting storage tier with much lower latency than SSDs. LINBIT has optimized DRBD for when its metadata is stored on PMEM/NVDIMM. This article relates to both: Traditional NVDIMM-N: Some DRAM is accompanied by NAND-flash. On power failure, a backup power source (supercap, battery) is used to save the contents of […]
