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...

VirtuCache Improves the Performance of Equallogic Appliances for VMware VMs and Bare-Metal Linux Servers

By deploying VirtuCache in Dun & Bradstreet's VMware environment, we demonstrated sub 10ms VM latencies for high, write-intensive, random storage IO, which in turn facilitated the P2V of their database servers.

Shared Disaster Recovery Infrastructure using CEPH storage.

Why deploy Disaster Recovery(DR) infrastructure when you already have backups? The main reason to deploy DR infrastructure is to protect against the rare case where you lose your entire datacenter. In case of a datacenter wide outage, you can flip over to your offsite DR data center. The DR datacenter is a replica of your entire production infrastructure, from applications running in VMs to servers, storage, and network configuration. DR and backups though related are two different things...

VirtuCache doubles VM densities at Myers Briggs Testing Institute

MBTI is a not-for-profit organization that improves the performance of people and organizations. They are best known for Myers-Briggs tests, the world’s foremost personality assessment tests used by institutions to help employees better understand themselves and how they interact with others. Main Challenges MBTI wanted to repurpose few of their expensive Dell C6420 servers to run additional applications, which meant that they would need to increase the number of existing VMs deployed...

Seagate Chooses VirtuCache for its 1200 Accelerator Product Line to Increase VM Densities for VDI Deployments

Seagate’s Enterprise SSD business unit manufacturers and sells high performance enterprise grade Solid State Drives (SSDs). Seagate realized that enterprise SSDs were well suited for the fast growing Virtual Desktop Infrastructure (VDI) space. Since most VDI deployments use VMware vSphere, Seagate was interested in partnering with a software vendor that could compliment their SSDs to address storage IO issues in VMware based VDI deployments. Listed below are the specific criteria that...

Caching from SAN to in-Host SSD to Improve Performance of Call Center Workflow Management

Call Center Workflow Management software is storage IO intensive since it deals with ingesting and analyzing large volumes of audio. By caching from slower storage to in-host SSDs/DRAM, VirtuCache improves storage performance considerably thus improving performance of Call Center Workflow software running within VMs.
