VirtuCache Customer Benefits
  1. Deploying VirtuCache significantly reduces storage latencies regardless of how random or high the storage throughput. This helps our customers realize:

    1. Higher VM density. Typically storage IO is the main reason for a smaller number of VMs deployed on each ESXi host. By eliminating storage IO bottleneck, it is possible to increase the number of VMs deployed on the host.

    2. Improved application performance within VMs. By eliminating storage IO issues, enterprise applications, especially databases, search engines, ERP, business intelligence, log management, SIEM and other IO intensive workloads run a lot better within VMs.

    3. Improved end user experience for Virtual Desktops. If VDI deployments suffer from long boot times, momentary freezing of desktop applications, locking of anti-virus VM – all symptoms of high storage latencies, then our solution can help solve these problems.

  1. Postpones storage network and appliance upgrades. If you are looking to upgrade your storage appliance, HBA or SAN switch for purposes of improving throughput or reducing latencies, it will be a lot cheaper to use VirtuCache with a host based SSD (or spare in-host RAM) to get comparable performance improvement from your existing SAN infrastructure versus doing a SAN upgrade. Furthermore, unlike in a SAN upgrade, you do not need to upgrade your entire infrastructure. You can pick and choose the ESXi hosts you would like to accelerate. VirtuCache with in-host SSD (or in-host RAM) is a good way to get improved performance from your existing storage infrastructure, no matter how slow or old.

  1. 10X cheaper than a SAN upgrade. To deploy VirtuCache, all you need is our software and an enterprise grade SSD (or spare in-host RAM). An enterprise grade SSD cost less than $1/GB and does 100,000 IOPS at less than 10 millisecond latencies from within a VM, and our software license fees start at $3000. On the other hand, for a SAN upgrade, at the very least, you would need SSDs in your storage appliance. Storage vendor branded SSDs cost substantially more than if the same SSDs were bought retail . Additionally you might need to upgrade the HBA in each host, upgrade the SAN switch, and if your appliance supports only a limited amount of SSDs replace the storage appliance itself. In comparison, the cost involved in deploying VirtuCache with in-server SSDs is an order of magnitude less than the cost involved with a SAN upgrade. Also with us you can start small by deploying our solution on only one host as a first step, in which case all you need to spend on is license fee for only one host and one SSD, that’s all. If you like the experience, you can buy a few more licenses and SSDs every quarter for the remaining hosts in your environment. This is in stark contrast to a large one-time capital expense on upgrading the appliance and SAN.

  1. Reduced network traffic. Since the majority of the requests are now being served from in-server SSD (or RAM), traffic on the storage network is substantially reduced.
