This topic describes how to customize the initial system set up requirements for memory, number of CPUs, storage disks, and network configuration.
The OVA file that you use to install the Delphix Engine is configured for the minimum system requirements. You can customize these to match the capabilities of your specific system.
- Follow the initial installation instructions for Installing the Delphix Engine.
- Shut down the guest operating system and power off the Delphix Engine.
- Under Getting Started, select Edit Virtual Machine Settings.
- You can now customize the system settings.
|Memory Size||Set to 64GB or larger based on sizing analysis. In the Resource Allocation panel, ensure that Reserve all guest memory is checked.|
|Number of CPUs||Allocate 8 vCPUs or more based on your Delphix licensing. vCPUs should be fully reserved to ensure that the Delphix Engine does not compete for CPU cycles on an overcommitted host.|
|Supported Controllers||Delphix only supports LSI Parallel controllers.|
|Disks for Data Storage||Add virtual disks to provide storage for user data such as dSources and VDBs. The underlying storage must be redundant. Add a minimum of 150GB per storage disk. All virtual disks should be the same size and have the same performance characteristics. If using VMFS, use thick provisioned, lazy zeroed disks. To alleviate IO bottlenecks at the virtual controller layer, spread the virtual disks across all 4 virtual SCSI controllers.|
|Data Storage Multipathing Policy|
For EMC storage, the multipathing policy should always be set to round-robin (default for 5.X). Additionally, change the IO Operation Limit from the default of 1000 to 1. This should be strongly considered for other storage platforms as well.
|Network||The network configuration is set to have a VMXNET3 network adapter. VMXNET3 is a tuned network interface that is included with the VMtools provided in the OVA file. |
It will be assigned to VM Network
Dedicate Physical NICs to the Delphix Engine
- After making any changes to the system settings, power on the Delphix Engine again and proceed with the initial system configuration as described in Setting Up the Delphix Engine.
