This article is Part 3 of a seven-part series that provides best practices and recommendations for configuring VMware vSphere 5.x with Oracle ZFS Storage Appliance to reach optimal I/O performance and throughput. The best practices and recommendations highlight configuration and tuning options for Fibre Channel, NFS, and iSCSI protocols.
The series also includes recommendations for the correct design of network infrastructure for VMware cluster and multi-pool configurations, as well as the recommended data layout for virtual machines. In addition, the series demonstrates the use of VMware linked clone technology with Oracle ZFS Storage Appliance.

The Oracle ZFS Storage Appliance product line combines industry-leading Oracle integration, management simplicity, and performance with an innovative storage architecture and unparalleled ease of deployment and use. For more information, see the Oracle ZFS Storage Appliance Website and the resources listed in the "See Also" section at the end of this article.
Note: References to Sun ZFS Storage Appliance, Sun ZFS Storage 7000, and ZFS Storage Appliance all refer to the same family of Oracle ZFS Storage Appliances.
Be sure to alter the NFS and TCP/IP advanced settings prior to starting the tests or putting your VMware servers in production. These options are extremely important to ensure high availability of the NFS datastores in a failover/failback situation with the Oracle ZFS Storage Appliance.
Table 1 shows the advanced settings. To alter the options listed in Table 1, go to the VMware vCenter 5.x server and select a VMware server. Select the Software tab and click Advanced Settings. See Figure 1 and Figure 2.
Note: This configuration must be performed on all VMware host members of the cluster. A reboot of each VMware host is required in order to activate the new settings.
