Improving Performance of Log Management Application at a Service Provider

Business Intelligence, Log Management, Security Information & Event Management (SIEM), Search and Analytic software like Splunk, Elastic Search, Cognos, HP Vertica, HP Autonomy, need to provide real-time visibility into large volumes of fast changing data. When these applications are deployed in traditional VMware VMs connected to centralized storage, such large volume of write and read operations puts pressure on existing storage infrastructure resulting in much slower than real-time...

Replaced PernixData for vGPU based VDI

First of all - PernixData was a good host side caching software. Unfortunately for their customers, after they were acquired by Nutanix, Nutanix end-of-lifed their software. Our software, called VirtuCache, directly competes with PernixData FVP.

Reducing Write Latencies in CEPH Storage

CEPH is a popular open source storage software. However its write latencies are high. VirtuCache caches CEPH volumes to in-host SSDs and by doing so reduces VM level latencies considerably.

Reducing Build Times for DevOps

Problem definition: ServiceNow's Itapp Dev/Ops team wanted to improve storage performance from their existing storage appliance and storage network without requiring a hardware refresh. Solution: Virtunet’s VirtuCache software improves the performance of any SAN based storage appliance and storage network, no matter how old or slow. With VirtuCache, the performance improvement that customers get from their existing storage infrastructure rivals the performance of all-SSD arrays. VirtuCache...

Reducing latencies in vGPU assisted VDI

VirtuCache is installed in VMware vSphere kernel. It then automatically caches frequently and recently used data from any backend storage to any high speed media (RAM/SSD) in the VMware host. By bringing large amounts of 'hot' data closer to the VMware host GPU and CPU, VirtuCache improves the performance of all applications running within VMs including GPU assisted operations.

A Counter Intuitive Approach to Solve the High Capacity, Low Latency Requirements for Video Storage

By not using dedupe, compression, or RAID, using slow HDDs in centralized storage, and moving SSDs to compute hosts, we arrived at low price per capacity and performance for video storage.

Here are unique requirements of video storage, some are obvious and others not so much, that inspired us to put together a different architecture than the conventional storage OEM design.

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. They were looking for the below list of features from their new storage: The ability to sustain a loss of any one component – server, HDD, SSD, NIC card, software instance etc; The ability for this storage to interface with VMware over iSCSI;...

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 improving storage performance, Virtucache was able to improve the performance of Jenkins based Continuous Integration process, which in turn resulted in quicker build-test cycles.
