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…
Storage Performance
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.
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….
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…
There are only a few applications, financial trading software being one example, that require very low latencies, lower even than what’s possible with an all-flash array (AFA). VirtuCache caching to in-host RAM results in lower VM latencies than an AFA. This is because RAM latencies are an order of magnitude…
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.
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…
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.
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.
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…
