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 […]
