Giving accurate values for expected system-level performance on the ZFS Storage Appliance is not possible, as it depends on many parameters - such as client workload, feature set used, memory size, network interfaces type, number of disks, optional use of logzilla and/or readzilla (SSD), pool layout (mirror vs raidz2), filesystem recordsize and FC/iSCSI LUN volblocksize.

However, this document will give you some basics which may help you to estimate what could be expected and give you some best practices to advise on the best configuration for the customer.

Please note : This document is not intended to be used in isolation for performance troubleshooting. Please refer to and use the ZFSSA Performance Troubleshooting resolution path document (See Document 1331769.1) to guide through pre-requisite stages of performance problem separation, clarification, categorization, basic system health-checks and then further information gathering - before looking to compare customer system performance with the information described in this document.


To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - Disk Storage ZFS Storage Appliance.



This documentation provides some guidelines but will not replace a serious and reliable benchmark based on genuine workload from the customer needs.
