VMware SSD and RAM Cache for Dell VRTX

Dell's PowerEdge VRTX hyper-converged appliance can either have all hard drive datastores or all SSD datastores, but you can't have SSDs act as tiering or caching media for VRTX volumes. That's where VirtuCache comes in.

PetaByte Scale Enterprise Grade Server SAN Storage for The Creation Museum

Creation Museum in Kentucky, USA is a museum about Bible history and creationism. Their storage needs were typical of a museum, requiring large amounts of storage for digital multimedia content related to the various exhibits at the museum.

Improving Storage Performance at The Ark

The Ark Encounter, in Williamstown, Kentucky, features a full-size Noah’s Ark built according to the dimensions of the Bible. Answers in Genesis (AiG) is the Christian ministry responsible for The Ark Encounter. AiG's IT department had a few ESXi hosts connected to their HP Store VSA. As a result of increased attendance at the Ark, their VMware workload increased dramatically, which in turn resulted in performance issues within VMs. AiG turned to VirtuCache to mitigate their storage...

CEPH Storage is Ideally Suited for Disaster Recovery (DR) Infrastructure

CEPH storage from Virtunet has all the features of traditional iSCSI SAN with the exception that it is reasonably priced because it uses commodity servers with all off-the-shelf hardware. And so it is ideally suited for backup and DR storage which needs to be cheap above all else.

Improving Jenkins Performance

By caching hot data to in-VMware host NVME SSD and RAM, VirtuCache was able to improve the performance of Jenkins based Continuous Integration(CI) process, which in turn resulted in quicker build-test cycles.

Improving Performance of Microsoft Dynamics AX ERP

Microsoft Dynamics AX transaction processing is write intensive and its reporting is read intensive, thus putting pressure on customer's existing storage infrastructure. By caching frequently used data from customer's existing storage to in-host SSDs, VirtuCache was able to reduce read and write latencies for AX running within VMware VMs.

VirtuCache Helped Reduce Storage Capex at a SaaS Provider

VirtuCache accelerates storage appliances to the same extent regardless of whether they have faster SAS hard drives or slower SATA drives, and regardless of the age and speed of SAN. Thus we help postpone a SAN upgrade, or if the customer is looking at a capacity upgrade, selecting an appliance with cheaper SATA hard drives would suffice. We save them capex dollars either way.


VirtuCache Doubles VM Density at Cloud.com

Cloud.com provides cloud and infrastructure orchestration software for service providers. They have an extensive internal dev/ops environment. Cloud.com wanted to re-purpose few of their expensive Dell C6220 servers to run additional applications, which meant that they needed to increase the number of existing VMs deployed on each host. As is often the case, there was plenty of CPU, memory, and networking capacity available on each one of the servers, and it was only storage latencies...

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.
