VirtuCache Improves Hadoop Performance within VMs at Stanford

Typically Hadoop workloads are run on bare-metal servers. However since Stanford’s School of Medicine was 100% virtualized, and because their security, monitoring & management tools were integrated within VMware, it was easier for them to deploy Hadoop within VMs, instead of provisioning new physical servers. The biggest challenge Stanford faced with Hadoop VMs was low throughput and high latencies for writes to disk. Deploying VirtuCache resulted in write latencies in Hadoop reducing...
