Virtunet powers storage in 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, along with The Creation Museum, in nearby Petersburg, Kentucky.

AiG's IT department had a few hosts spread across The Ark and The Creation Museum. Their VMware hosts were connected to HP LeftHand Networks appliances. As a result of increased ticket sales and new development projects at the The Ark and The Creation Museum, their VMware workload increased dramatically, which in turn resulted in performance issues within VMs.

AiG turned to VirtuCache to mitigate their storage latency issues. By caching frequently used data to in-host SSDs, Virtunet immediately resolved their storage performance issues and without requiring AiG to upgrade any of their SAN or storage equipment.

Virtunet Systems is excited to present at the upcoming Northern MISAC Chapter meeting this month!

Improving the performance of CEPH storage using host side caching software for VMware

 

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

Healthcare : Virtualizing CPSI and improving end user response times for CPSI running in VMs

 

Virtunet's services and software helped Klickitat Valley Health (KVH) migrate CPSI EMR software from physical hardware to virtual. Our quote for P2V and enterprise wide hardware refresh for KVH was comparable to the quote from CPSI for just the CPSI HIS hardware upgrade.

Virtunet Write-Back Caching Improves the Performance of EMC VNX Appliance Without Requiring Any Appliance or SAN Upgrade

  Accelerating EMC VNX appliances is a popular use case for Virtunet’s VirtuCache host side caching software.
EMC’s VNX appliances have 3 shortcomings that VirtuCache fixes without touching the SAN and Appliance,
  1. They are expensive in terms of $/IOPS
  2. Even the high-end VNX 7500 can accommodate only 2TB of SSDs per appliance
  3. SSDs in the VNX that are used for tiering data from HDDs do not cache writes, hence writes are not accelerated

There are two ways to improve the performance of VNX. One is to install EMC’s FastCache SSDs in the appliance, the other is to use VirtuCache host side caching software to cache data from VNX to in-host SSDs.
