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 […]

Performance Gains with DRBD 10

A key factor in evaluating storage systems is their performance. LINBIT has been working to further improve the performance of DRBD. The recent DRBD 10 alpha release demonstrates significant gains. The performance gains particularly help with highly concurrent workloads. This is an area that has been steadily rising in importance, and looks set to continue […]
