February 3,2021; Daejon, Korea. Chungnam National University Hospital (CNUH) uses VirtuCache with Intel Optane SSD and host RAM to improve VMware Horizon VDI performance.
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. SSD in the ESXi host will perform…
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…
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.
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.
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,…
ServiceNow’s Dev/Ops team wanted to improve storage performance from their existing HP 3PAR all-flash storage appliance and iSCSI storage network. VirtuCache Deployment Virtucache was installed on 24 ESXi hosts caching to 1.6TB PM1725 PCIe flash cards. Each PM1725 SSD was performing at between 100-250MBps throughput at 1-5ms VM level latencies….
