Hardware recommendations for a host

The following is a hardware recommendation for a virtualization platform host, running PureConnect software as a guest.

The hardware that we recommend for a host is greater than the minimum hardware requirements provided by the virtualization platform vendor to run the virtualization platform. These recommendations are based on extensive lab tests and experience with the PureConnect software. Consult your virtualization platform vendor for assistance in determining appropriate hardware specifications for your environment.

Component	Recommendation
Processor	64-bit x86 CPUs with Intel VT or AMD-V technology enabled.Hardware Data Execution Prevention (DEP), specifically Intel XD bit (execute disable bit), or AMD NX bit (no execute bit), must be available and enabled. Caution! The number of CPU cores that you must assign to the hypervisor host to provide adequate processing for the guest virtual machines varies depending on many factors, such as hypervisor software, hardware specifications, the number of active guest VMs, the processing load of the guest VMs, the amount of network traffic, the need for immediate processing of communications, and others. Minimum Processor Speed: 2.0Ghz or faster in Intel Nehalem class or Intel Xeon 5400, 7100/7300 or 7200/7400 @ 2.5Ghz or greater Recommended: Intel Nehalem 2.40 GHz or greater Examples: E5620 2.40Ghz, X5677 3.47GHz
RAM	Minimum 8 GB RAM for the host. Minimum 3 GB for each CIC guest unless otherwise specified in Supported for virtualization (Hyper-V and VMware).
Available storage space	120 GB or greater for the host partition. 300 GB of Fixed or Thick Provisioned storage space for each CIC guest.This storage space is required for CIC tracing and debugging dump files.
Network adapters	Modern adapters have a speed of 1Gb/s or higher and support RSS and VMQ. Notes: Depending on the number of guests and network transmissions, 1Gb/s may not be sufficient. If you are using Windows Server 2012 R2 Hyper-V, we recommend that you enable the Receive Side Scaling (RSS) feature on your virtual NICs so that Hyper-V uses its vRSS feature to spread the processing of network activity across the multiple virtual CPU cores that are assigned to the virtual machine.
