Virtualizing CPSI

Use Case:
Storage Performance

Astoria, OR


  • The physical hardware that CPSI was running on was obsolete.
  • The customer wanted to manage CPSI storage, network, and server infrastructure much like they managed their other EMR apps, using vCenter.
  • They wanted to improve performance / reduce latencies that end users were experiencing within the CPSI application.


  • CMH migrated from obsolete CPSI hardware to virtual CPSI running in VMware VMs, and with better performance than what they were experiencing with physical hardware before.

Virtualizing CPSI

The Virtunet Difference
The customer selected Virtunet because:
  • Virtunet migrated physical CPSI to virtual for much cheaper than Evident's (CPSI parent company) quote.
  • Virtunet's VirtuCache software improved the performance of CPSI by servicing all storage IO from in host NVME flash drives.
  • Columbia Memorial Hospital (CMH) is a hospital on the Columbia river in NW Oregon.

    This project was a combination of Virtunet’s professional services to virtualize CMH’s CPSI EMR system and deploying Virtunet’s VirtuCache software to improve the storage performance of CMH’s VMware infrastructure.

    Needing a Hardware Refresh
    CMH was running CPSI on IBM physical servers backed by IBM SAN based storage appliance.
    CMH’s CPSI hardware was out of warranty. At a minimum CMH was looking for hardware refresh for CPSI.  After receiving a quote from CPSI to upgrade solely the CPSI servers, CMH’s IT Manager explored other options for a complete refresh of their infrastructure.

    Virtunet Systems vs. CPSI
    Below is how our offer competed with CPSI’s proposal for a hardware refresh.

    Quote by Virtunet Quote by CPSI
    Services for migrating all their servers (mix of physical servers and Hyper-V VMs) to a 100% virtual infrastructure running VMware. Evident’s quote didn’t include any other VM or server other than CPSI HIS.
    Hardware included.
    ·        3 new servers (256GB RAM, 48 cores)
    ·        24TB usable storage
    ·        9TB SSDs
    ·        Redundant 10gbps switches
    Hardware included:
    ·        2 servers (128GB RAM, 12 cores)
    ·        24TB usable storage
    ·        600GB SSDs
    ·        No network upgrade
    Software licenses for Virtunet host side caching software and VMware vSphere. No additional software.


    Improving the performance of CPSI VM using VirtuCache
    VirtuCache is software from Virtunet that improves the performance of VMware VMs by caching all VM reads and writes to in-host SSD or RAM. CMH deployed VirtuCache on their ESXi hosts to improve the performance of the newly virtualized CPSI VM, and other mission critical VMs in their VMware cluster.

    Benefit to CMH
    The cost of the entire infrastructure upgrade was comparable to the quote from CPSI to migrate only the CPSI application to newer hardware.

    The performance of all CMH applications (including CPSI) now running in VMware VMs was much better than before because almost all the data was now being served by VirtuCache from in-host NVME drives.
