Performance Tiering and Read Caching in HPE MSA versus Virtunet VirtuCache.

December 11, 2017:

Only read performance is improved by HP MSA's internal caching and tiering features.1 In comparison, VirtuCache improves the performance of reads and writes for MSA, and it does so by caching to in-VMware host SSD or RAM. There are other differences as well.

Improving Performance of Log Management Application at a Service Provider

May 2, 2018: 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...

Replaced PernixData for vGPU based VDI

May 10, 2017

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

July 22, 2016:

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.

Improving VDI Performance at Fairbanks Sewer and Water

September 21, 2016:

Fairbanks Sewer and Water (FSW) wanted to improve the performance of their server VMs (especially their server VMs running SCADA) and Horizon View virtual desktop VMs. Their virtual desktop VMs were exhibiting all the classic symptoms of storage related issues – cursor freezes, long boot times, long VM provisioning times, jittery audio/video.

CEPH Storage with Server Side Caching for Genomics

March 7, 2019:

As it relates to storage, genome sequencing workflow has two requirements.

  1. Need for cheap ($/GB) Petabyte scale storage.

  2. Need for faster processing of Genome files under analysis, many of which are a few hundred GB in size.

Reducing Build Times for DevOps

April 12, 2018: ServiceNow's Itapp Dev/Ops team wanted to improve storage performance from their existing HP 3PAR storage appliance and iSCSI storage network without requiring a hardware refresh. VirtuCache Deployment: Virtucache was installed on 3 ESXi hosts caching to 1.6TB PM1725 PCIE flash cards. In our tests the PM1725 SSD did 250MBps at 1ms VM level latencies. VirtuCache was configured to cache both reads and writes for all VMs (Write-Back caching). Writes were replicated to another...

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

June 14, 2017: 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...

Reducing latencies in vGPU assisted VDI

October 1, 2016:

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.

VirtuCache on ESXi 7, accelerating Netapp Ontap Select Storage

April 15, 2020:

City of Mountain View is using VirtuCache to improve the performance of Netapp's Ontap Select storage software. They were one of our first customers to upgrade to ESXi 7.0 and so they had to upgrade VirtuCache as well.

We announced General Availability of VirtuCache for ESXi 7 within 2 weeks of VMware's ESXi 7 release date.
